Current refinance guidelines, updated from one source.
Treat these as the program’s fixed points: the conventional cap on a one-unit principal residence and the line above which mortgage insurance applies, the no-appraisal streamline on an existing FHA loan, the IRRRL fee and seasoning clock on an existing VA loan, and the score floor and ratio ceiling the automated finding works from. The ladder below adds the FHA appraisal route and the jumbo lanes.
One-unit principal residence; mortgage insurance above 80%
Conventional leverage for a rate-and-term file: 95% of value on a one-unit principal residence, 97% on the first-time-buyer programs where allowed, with the old loan, the costs, and a purchase-money second inside the new balance. Mortgage insurance attaches above 80%, may be cancelled on request at 80% of the original value, and ends on its own at 78%.
An existing FHA loan, refinanced with a net tangible benefit and a limited credit review
The streamline is the lightest refinance FHA offers: no appraisal, a limited credit review, and a requirement that the new loan deliver a net tangible benefit, tested against the loan being replaced and its payment history. The premium continues. Where an appraisal is used, FHA’s rate-and-term reaches 97.75% on an owner-occupied principal residence.
An existing VA loan, no VA appraisal; seasoning of 210 days and six payments
For a South San Francisco veteran with a VA loan, the IRRRL replaces it at a 0.5% funding fee, financed or waived for an exempt veteran, with no VA appraisal and no cash returned; the loan being replaced must be seasoned 210 days and six payments, and the new loan must pass VA’s net tangible benefit test. A home the veteran once occupied and now rents is still eligible on the wholesale program.
DTI to 50%; jumbo from 660 on its lanes
Score and ratio for a South San Francisco refinance: 620 is the conventional floor, 50% the automated ratio ceiling, and the finding weighs the rest of the file. The jumbo lanes, for balances above the conforming limit, start at 660, reach 90% of value on the headline lane, lend to $5,000,000, and hold the ratio to 50% on the fixed lanes with reserves per the lane.
| Program | Loan being replaced / occupancy | Maximum LTV | Conditions |
|---|---|---|---|
| Conventional rate-and-term (Fannie Mae / Freddie Mac) | One-unit principal residence | 95% | limited cash-out: the old loan, the closing costs and a purchase-money second roll in, incidental cash only; 97% where the existing loan is agency-owned and the first-time-buyer program allows; mortgage insurance above 80% |
| FHA streamline | Existing FHA-insured loan | No LTV test | appraisal not required; net tangible benefit; limited credit review; the previous loan’s seasoning and payment history apply; FHA mortgage insurance continues |
| FHA rate-and-term | Principal residence (owner-occupied the previous twelve months) | 97.75% | with an appraisal and full credit review; FHA mortgage insurance on the new loan |
| VA IRRRL | Existing VA loan; a home the veteran previously occupied | No LTV test | 0.5% funding fee (financeable; exempt veterans pay none); no VA appraisal; net tangible benefit; seasoning the later of 210 days and six payments |
| Jumbo rate-and-term (wholesale lanes) | Above the conforming limit | 90% | 660+ score on the headline lane, loans to $5,000,000, DTI to 50% on the fixed lanes; reserves and the appraisal count per the lane |
A refinance that returns cash is a cash-out refinance and is covered by the conventional, FHA, VA and jumbo cash-out programs; a line of credit that leaves the first mortgage in place is the HELOC program. Each carries its own leverage and its own rules.

What a rate-and-term refinance is — and how the file is qualified.
A rate-and-term refinance is simple to describe and particular in its rules. The four cards below cover what the new loan is and what it may pay off, which of the four programs applies to the loan being replaced, how the benefit test and the break-even decide whether the refinance pays, and what to do when the real goal is cash rather than terms.
For the program overview, see Lendmire’s refinance program, or the statewide guide at Refinance in California; when the goal is cash, see the cash-out refinance program.
One new loan replaces the old one
Replacing a mortgage means paying it off with a new one on the same home. The new balance is the old balance plus the closing costs, where they are rolled in, and nothing comes back to the borrower beyond an incidental amount; paying off a line of credit or a non-purchase-money second through the loan turns it into a cash-out, which is a different program with its own leverage.
Four programs, one question: which applies
Four programs serve four situations. The conventional refinance fits most South San Francisco homeowners, including FHA borrowers leaving the premium behind. The FHA streamline fits an FHA borrower who wants a lower payment with the least paperwork. The VA IRRRL fits a veteran with a VA loan, including a home once occupied and now rented. The jumbo lanes fit a balance the conforming limit cannot hold.
The benefit test and the break-even
The arithmetic is plain: closing costs divided by the monthly saving gives the months to break even, and the interest over the new term set against the interest remaining on the old loan says what the term reset costs. HUD and VA write a version of this test into the streamline and the IRRRL; the conventional refinance leaves it to the homeowner, which is why Lendmire runs it before anything is ordered.
When the goal is cash, not terms
Equity can be borrowed two ways, by replacing the first mortgage with a larger one or by adding a line behind it, and neither is a rate-and-term refinance. When the question in South San Francisco is how much cash the home can release, the answer is in the cash-out guides; when the existing first mortgage is worth keeping, it is in the HELOC guide. This page covers the loan that changes terms and nothing else.
Every input below is yours: the South San Francisco value, the current balance, the current rate and years remaining, the program, the new term, the new rate, the closing costs, and the escrows. The caps, the mortgage-insurance line, the fee, and the ratio ceiling come from the programs; the new loan, the payment, the saving, and the break-even follow from the arithmetic above.
Where South San Francisco’s mortgages were written — and what a refinance changes.
Three Census figures frame a South San Francisco refinance file. Ownership says how much of the market holds a mortgage that can be rewritten, the median value says how much room a typical balance has under the leverage cap, and household income says what ratio a typical payment produces.
These are context figures, not underwriting inputs. A value well above the balance makes the appraisal a formality and the mortgage-insurance line easy to clear; a value close to the balance makes both decisive. The market sets the cushion, the program sets the cap.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct South San Francisco neighborhoods, distinct refinance questions.
South San Francisco is not one housing stock, and the refinance question changes with it: the vintage of the mortgage, the equity built since, the project review on a condominium, the conforming limit on a high-value home. Sort the neighborhoods by what a refinance there turns on.
Rentals held for years
A South San Francisco rental held for years refinances rate-and-term on the conventional or jumbo route at the investment occupancy’s own leverage, stated for the file, with no rescission period at funding and the rent counted as the agencies allow. A veteran’s former home now rented is eligible for the IRRRL. Cash out of a rental is a different program with its own guide. Median household income in South San Francisco sits near $136,578 on the latest Census estimate.
High-value homes near the limit
A high-value South San Francisco home refinances on the agency route when the new balance fits under the limit and on the jumbo lanes when it does not. The rate-and-term arithmetic is the same; the documentation, the reserves, and the appraisal count change with the lane. An owner near the line sometimes pays the costs at closing to stay conforming. The median owner-occupied home value in South San Francisco runs near $1,188,800 on the latest Census estimate.
Newer infill and recent purchases
Recent purchases refinance for terms rather than for equity. The conventional cap in the snapshot is generous enough for most South San Francisco files, and the question is whether the new loan lands above or below the insurance line; rolling the costs in can push it over, paying them at closing can keep it under, and the review places it before the appraisal. South San Francisco is home to about 64K people and sits within the San Francisco-Oakland-Fremont, CA area.
Long-held close-in homes
An owner on a close-in South San Francisco street with years of payments behind the loan is the classic shorter-term candidate: the appraisal is a formality, the loan sits far below the insurance line, and the interest saved by compressing the remaining years is the whole point. The calculator’s interest comparison is where that decision is made. About 41% of South San Francisco’s households rent — roughly 8,960 renter households on the latest Census estimate.
Condominiums and townhomes
Townhomes in a planned development and condominiums in a tower refinance differently in one respect: the condominium brings the project review. The FHA streamline and the VA IRRRL do not re-review the project on an existing government loan, which is one reason an eligible South San Francisco borrower in a building with questions may prefer them. Roughly 12,878 South San Francisco households own their homes on the latest Census estimate — 59% of all households, the pool a refinance draws on.
Two- to four-unit homes
Small multi-unit homes refinance on every route the existing loan allows, with their own cap and with the rents helping the ratio within the rules. The FHA streamline and the VA IRRRL apply to the government loan on the property exactly as on a house; the conventional route adds the rent schedule and the occupancy’s leverage. On a South San Francisco home at the median value, a conventional rate-and-term refinance at the leverage cap allows a new loan up to $1,129,000 — the existing loan, the closing costs, and a purchase-money second lien are what it may pay off.
The rules do not change with the street. Every South San Francisco file is checked the same way: the loan being replaced against the program, the new loan against the cap where a value test applies, the costs against the saving, and the borrower against the score and the ratio.
Four reasons South San Francisco homeowners rewrite the mortgage.
The purpose of a refinance decides its shape. The four cards below take the common South San Francisco purposes one at a time: what the homeowner is after, which program delivers it, and the figure in the file that decides whether it works.
Shorten the term
A shorter term is the refinance that costs more each month and less in total. The ratio is tested on the new, higher payment, the appraisal and the cap apply as on any conventional file, and the saving shows up as interest avoided rather than as cash in the budget. The calculator sets the interest over the new term beside what remains on the old loan.
Lower the monthly payment
A lower payment comes from a lower rate, a longer term, or both. The first is a saving; the second is a loan stretched across more years, which can cost more in interest even as the payment falls. The break-even on the costs and the interest comparison over the two terms are the figures that separate a refinance that pays from one that only feels like it does.
Get rid of mortgage insurance
Rising values in South San Francisco have put many FHA borrowers at or below the line where a conventional loan carries no mortgage insurance, and the refinance that moves them there removes a premium that would otherwise run for years. The file needs an appraisal and the conventional credit review; the saving is the premium plus whatever the rate change adds or subtracts.
Remove or add a borrower
Adding a borrower, a spouse or a family member whose income helps the ratio, or removing one who no longer belongs on the note, is done through a refinance. The qualifying borrowers must carry the loan on their own numbers, the title is conformed at closing, and the program is the one the existing loan points to; a buyout funded by the loan is a cash-out file.
Estimate the new payment and the break-even on a South San Francisco home before requesting a quote.
Enter the South San Francisco value, the current balance, the current rate and the years left on the loan, choose the program and the new term, set the closing costs you expect, and the calculator returns the new loan, the new payment, the monthly change against the current principal and interest, the months to break even, the interest over the new term beside what remains on the old loan, and the ratio against the ceiling.

Illustrative starting assumptions: a $1,190,000 home value near South San Francisco’s median owner-occupied value, a $833,000 current balance, a current rate and remaining term you enter, closing costs seeded at $16,500 as an editable placeholder (not a fee quote), a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated for California (U.S. Census Bureau). Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

Same home, four ways to refinance it.
The same home can be refinanced four ways, and the routes differ more than the labels suggest: a conventional rate-and-term with an appraisal and the leverage cap, an FHA streamline or a VA IRRRL on an existing government loan with no appraisal and a benefit test, or the jumbo lanes above the conforming limit. The cards below put them side by side for a South San Francisco home.
Conventional, streamline, or jumbo.
The conventional rate-and-term refinance replaces whatever first mortgage is on the home with an agency loan: value tested by appraisal, leverage capped as in the snapshot, mortgage insurance ending at the line, the old loan and the costs inside the new balance. It asks the most of the file and reaches the most homeowners, including FHA borrowers ready to shed the premium. See the conventional loan program.
Two streamlines for two existing loans. The FHA streamline refinances an FHA loan with no appraisal, a limited credit review, and a net tangible benefit; the premium continues. The VA IRRRL refinances a VA loan with no VA appraisal, a small funding fee unless the veteran is exempt, a benefit test, and seasoning on the old loan. Both trade paperwork for a benefit test and return no cash. See the FHA and VA programs.
The jumbo refinance is the conventional file written larger: an appraisal, sometimes two, the lane’s leverage cap, a stricter credit floor, and reserves after closing. It replaces a jumbo first mortgage, or a conforming loan that has grown past the limit through costs, and returns no cash; the cash-out version lives on the jumbo cash-out page. See the jumbo loan program.
Refinance conventionally when the loan is conventional, when an FHA premium should end, or when a borrower must come off the note; use the FHA streamline or the VA IRRRL when the loan is already FHA or VA and the goal is a lower payment or a fixed rate; go to the jumbo lanes when the balance is above the limit. Go to the cash-out guides when the goal is cash.
What to prepare for a South San Francisco scenario review.
A conventional refinance documents income, assets, the property, and the loan being replaced; a streamline or an IRRRL documents mostly the loan being replaced. Here is the full set a South San Francisco review may ask for, so nothing waits on paperwork.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the transaction, the property, the automated finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
The program is simple to state and particular in its exceptions. Here are the local and file-level details that most often change a South San Francisco refinance between application and closing.
Use these checks to keep the South San Francisco file clean and fundable.
Before the appraisal is ordered: run the break-even on realistic costs, compare the interest over the new term with what remains on the old loan, and confirm which program the existing loan points to for the South San Francisco home.
- Run the break-even: Closing costs divided by the monthly saving is the break-even in months.
- Weigh the reset: Read the interest comparison in the calculator before choosing the term.
- Check the project: Conventional and jumbo refinances review the condominium project.
The costs are recovered only through the saving
A refinance that saves a modest amount each month against substantial costs can take years to pay for itself. The rule is simple: if the months to break even exceed the months the owner expects to keep the loan, the refinance does not pay, whatever the new payment looks like. A Lendmire review states the break-even in writing before any fee.
The term starts over unless you choose a shorter one
Resetting the term is the quiet cost of most refinances. The payment falls because the balance is spread across more years, and the interest paid over the life of the loan rises for the same reason. The fix is a shorter new term, which raises the payment back toward the old one and keeps the interest saving; the review runs both versions for the South San Francisco owner.
Condominiums add the project review on the conventional and jumbo routes
For a South San Francisco condominium the project review is the extra step: budget, reserves, litigation, commercial space, owner-occupancy mix, insurance. A project that passed at purchase usually passes again; one that has changed hands or added investors may not. The loan officer collects the association’s documents before the appraisal so the question is answered early.
The rescission period on a principal residence
Federal law gives the borrower a short window after signing to cancel a refinance of a principal dwelling, so the payoff and the funding wait until it has passed. Second homes and investment property refinances have no such window. A South San Francisco loan officer sets the signing date with the window in mind.
Mortgage insurance begins and ends at published lines
Where the new loan lands against the insurance line decides a large part of the payment. Rolling the closing costs into the loan can push a South San Francisco file just over the line; paying them at closing, or a slightly smaller loan, can keep it under. The review places the loan against the line before the appraisal is ordered.
From a South San Francisco scenario review to a new first payment.
From the first conversation to the new first payment, a South San Francisco refinance moves through four stages, and the first one, the review, is where most files should be decided. The rest is documentation, the appraisal where the program needs one, and the closing.
Scenario review
Start with the balance, the current rate, the years remaining, the value, the score, and the costs. A Lendmire loan officer identifies the program the existing loan points to, runs the new payment, the saving, the break-even, and the interest comparison, and provides the terms in writing before anything is ordered.
Application and automated finding
The application goes to the selected wholesale program and the automated finding comes back with the documentation the file needs; the FHA streamline and the VA IRRRL follow their own limited review instead. The finding sets the ratio ceiling and often trims the paperwork; the loan officer reads it before the appraisal is ordered.
Appraisal and underwriting
Value first, then verification. On a conventional or jumbo refinance the appraisal is the one input the South San Francisco owner cannot control; on a streamline or an IRRRL there is none. Underwriting reads the finding’s conditions, the payoff, and the benefit test where it applies, and, where the file supports it, approves the loan on the terms the review set out.
Closing, rescission, and funding
At closing the new loan is signed, the payoff is ordered, and after the rescission period on a home the borrower lives in, the old loan is retired and the new one begins. Second homes and investment property fund without the wait. The new servicer sends the first statement, and any saving the review showed starts with it.
A brokerage that runs the break-even honestly.
Three habits define a Lendmire refinance: the review comes before the application, the recommendation follows the break-even rather than the commission, and the terms are written down before the appraisal. The South San Francisco owner decides with the numbers and nothing has been spent.
The break-even, run before anything else
The arithmetic is run on the owner’s own figures before an application exists: the saving, the months to break even, the term reset. When the refinance does not pay, the recommendation is to wait, and that recommendation is given as readily as the other.
Shopped across wholesale programs
Lendmire places the file with the wholesale program that fits it, conventional, FHA, VA, or jumbo, rather than with the one program a single lender sells. A South San Francisco refinance is compared on the same numbers across programs before a route is chosen.
Terms in writing, before any fee
The review ends with written terms on a cautious value, and nothing is ordered until the South San Francisco owner agrees the plan is worth an appraisal where one applies. The appraisal is not ordered for a plan the review has already ruled out.

South San Francisco refinance FAQs
Before you request a South San Francisco refinance review, learn when a refinance makes sense, what it costs to get there, which program fits the loan you have, and what to expect from the process.
What is a rate-and-term refinance, and how is it different from a cash-out?
The difference is cash. A rate-and-term refinance can lower the payment, shorten the term, end mortgage insurance, fix an adjustable rate, or change the borrowers, and returns only incidental cash. A cash-out refinance exists to return cash. Paying off a line of credit or a non-purchase-money second through the loan makes the file a cash-out even when the borrower receives nothing.
When does refinancing actually make sense?
It makes sense for a reason you can name: a lower payment that recovers its costs, a shorter term that cuts the interest, an FHA premium that ends, an adjustable rate that becomes fixed, a name that comes off the note. It rarely makes sense for a payment that is only slightly lower, because the costs and the term reset eat the difference. The South San Francisco review says which case you are in.
What does a refinance cost to close?
Closing costs on a South San Francisco refinance are the price of the new loan: origination and third-party charges, prepaids, title, and recording, plus the IRRRL fee on a VA file. The written terms list them; the calculator lets you enter your estimate and shows how long the saving takes to recover them. Rolling them in avoids cash at closing and adds them to the balance.
Can I get rid of mortgage insurance by refinancing?
An FHA premium ends only by leaving FHA: a conventional refinance with the new loan at or below the insurance line. Private mortgage insurance on a conventional loan ends by request at the published line or automatically at the lower one, and a refinance is needed only when the value, not the original price, is what puts the South San Francisco loan under the line.
What is an FHA streamline, and who can use it?
Use it when your loan is FHA, you intend to stay FHA, and the new loan passes HUD’s net tangible benefit test. Skip it when the goal is ending the premium, which needs a conventional refinance at or below the insurance line, or when the loan is not FHA at all. A South San Francisco loan officer confirms the case details and the payment history first.
Why is there a waiting period after I sign?
The rescission period is the borrower’s right to change their mind on a refinance of a principal dwelling, written into federal law. A South San Francisco refinance signs, waits, then funds; the old loan is paid through the title company after the period, and the new loan’s term begins at funding.
Can I pay off a second mortgage or a HELOC with a rate-and-term refinance?
Yes for a second mortgage taken at purchase; no for one opened later or for a HELOC, unless the file is treated as a cash-out. Subordination is the other route: the second lien stays, its lender agrees to sit behind the new first mortgage, and the refinance proceeds as rate-and-term.
How long does a refinance take?
The sequence is fixed and the calendar is not. The review comes first and costs nothing; the application and the finding follow; the appraisal, where the program needs one, sets the pace; underwriting and closing follow; the rescission period runs on a principal residence before funding. A streamline or an IRRRL removes the appraisal step.
Can I refinance an adjustable-rate mortgage into a fixed rate?
Yes, on every route on this page. A conventional refinance converts an adjustable loan to a fixed one with an appraisal and the usual review; an FHA streamline or a VA IRRRL does the same on an existing FHA or VA loan with less paperwork, and VA counts the conversion from adjustable to fixed as a net tangible benefit on its own. The new loan is fixed for its full term, and the payment is known for every month of it.
How soon after buying or refinancing can I refinance again?
Conventional: no agency clock on the old loan, only the break-even. VA IRRRL: the seasoning in the snapshot, measured in days from the first payment and in payments made. FHA streamline: the previous loan’s seasoning and payment history. The second refinance pays only when the second set of costs is recovered by the second saving.
A South San Francisco mortgage, rewritten on current terms.
A South San Francisco refinance starts with arithmetic and ends with written terms. Send the mortgage statement and the goal; the loan officer returns the program, the new loan, the payment, the saving, and the months to break even, and orders nothing until you agree.
