Current refinance guidelines, updated from one source.
The block below holds the figures that frame a refinance file, read from Lendmire’s guideline sources and refreshed on this page when the agencies, HUD, VA, or the wholesale overlays change: the conventional leverage and the mortgage-insurance line, the streamline rules for an existing FHA loan, the IRRRL fee and seasoning for an existing VA loan, and the credit and ratio figures. The ladder underneath lists every route.
One-unit principal residence; mortgage insurance above 80%
The conventional rate-and-term refinance reaches 95% loan-to-value on the home the borrower lives in, with 97% only on the first-time-buyer programs for an agency-owned loan. It rolls in the old balance, the costs, and a purchase-money second; paying a non-purchase-money second or a credit line through it makes it a cash-out. Mortgage insurance begins above 80%; the owner may cancel it at 80% of the original value, and it falls away by itself 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
An existing VA loan can be refinanced to a lower rate or from an adjustable to a fixed rate through the IRRRL: a 0.5% funding fee that can be financed and that exempt veterans do not pay, no appraisal required by VA, a net tangible benefit, and seasoning of 210 days and six payments on the loan being replaced. The home may be a primary, second, or investment property where the veteran previously occupied it.
DTI to 50%; jumbo from 660 on its lanes
Score and ratio for a San Diego 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.
This page has four parts on the rate-and-term refinance. First, the new loan and the loan it pays off. Second, the conventional, FHA streamline, VA IRRRL, and jumbo options, and which one the existing loan points to. Third, the benefit test and break-even. Fourth, where a San Diego owner who wants cash goes next: the cash-out programs.
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
The new loan is a complete first mortgage. At closing, it pays off the existing first mortgage. Closing costs and prepaid items are financed into the new loan. On a conventional file, it also pays off a purchase-money second lien taken when the home was bought. The balance is otherwise unchanged, and only incidental cash comes back. The old payment ends; one new payment, on the new term and the new rate, replaces it.
Four programs, one question: which applies
The loan already on the home decides the route. A conventional loan, or an FHA loan whose owner wants the premium gone, refinances conventionally, with an appraisal and the leverage in the snapshot. An existing FHA loan that will stay FHA uses the streamline. An existing VA loan uses the IRRRL. A balance above the conforming limit uses the jumbo lanes, whatever the loan was before.
The benefit test and the break-even
A refinance pays when the owner keeps the loan past the break-even and the term reset does not give back the saving in interest. On an FHA streamline or a VA IRRRL the new loan must also deliver a net tangible benefit as the agency defines it, and VA requires the fees and costs to be recouped within its window when the new loan does not exceed the payoff. The San Diego calculator below runs all three figures.
When the goal is cash, not terms
Paying off a line of credit or a second lien that was not part of the purchase through the new loan makes the file a cash-out under the agency rules even when no cash reaches the borrower, so an owner with a HELOC behind the first mortgage should read the cash-out guide first. The rate-and-term refinance pays off the first mortgage, the costs, and a purchase-money second, and stops there.
Nothing in the formula is a quote. The new rate is a published weekly benchmark you can overwrite, the costs are your estimate, and the result is the shape of a San Diego refinance, not its terms: the loan, the payment, the saving, the break-even, and the interest comparison, which a loan officer then prices in writing.
Where San Diego’s mortgages were written — and what a refinance changes.
Scale, not quotation: the median value says what a typical San Diego balance sits under, the ownership rate says how many mortgages the market holds, and the median income sizes the ratio a typical payment leaves. The program figures above do not move with any of them.
Citywide figures provide general market context, not an appraisal or an income calculation. 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.

Distinct San Diego neighborhoods, distinct refinance questions.
The San Diego submarkets below show where the mortgages sit and what a refinance there asks: the program the existing loan points to, the value the cap is tested against, and the costs the saving has to recover.
Two- to four-unit homes
A San Diego owner living in one unit of a duplex, triplex, or fourplex refinances rate-and-term at the leverage the agencies assign to that occupancy, which the loan officer states for the file, with the other units’ rents entering the qualification as the agencies allow and a rent schedule in the appraisal. The one-unit figures in the snapshot are not its figures. San Diego is home to about 1.39M people and sits within the San Diego-Chula Vista-Carlsbad, CA area.
Rentals held for years
Landlords in San Diego refinance long-held rentals to fix a rate or shorten a term more often than to lower a payment, because the rent carries the loan either way. The conventional and jumbo routes serve the occupancy at its own leverage; the IRRRL serves a veteran who once lived in the home; the investment cash-out guide covers equity taken out. About 53% of San Diego’s households rent — roughly 279,312 renter households on the latest Census estimate.
High-value homes near the limit
A high-value San Diego 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. Roughly 251,100 San Diego households own their homes on the latest Census estimate — 47% of all households, the pool a refinance draws on.
Newer infill and recent purchases
New rows and recent infill in San Diego were bought at recent prices, often with small down payments, and a refinance on them runs into the insurance line first: the new loan, with the costs inside it, must sit at or under the published line to carry no mortgage insurance, and often does not yet. The streamline or the IRRRL serves an FHA or VA buyer there; a conventional buyer waits for equity or accepts the premium. The median owner-occupied home value in San Diego runs near $906,700 on the latest Census estimate.
Long-held close-in homes
Deep equity changes the refinance from a leverage question to a term question. On a long-held San Diego home the new loan sits well under the cap and the insurance line, and the choice is between a lower payment on a fresh thirty years and a shorter term that keeps the payment close and cuts the interest; the review runs both. On a San Diego home at the median value, a conventional rate-and-term refinance at the leverage cap allows a new loan up to $861,000 — the existing loan, the closing costs, and a purchase-money second lien are what it may pay off.
Condominiums and townhomes
Much of San Diego’s stock is attached housing, and a conventional refinance of a condominium adds the agencies’ project review to the file: the association’s budget, insurance, and investor share are checked before the appraised value is applied to the loan-to-value cap. Established buildings usually pass; newer or investor-heavy ones draw questions. A streamline or an IRRRL on an existing government loan skips the review. Median household income in San Diego sits near $108,077 on the latest Census estimate.
Housing stock shapes the appraisal and the equity; the program shapes the loan. The cards above are context for a San Diego file, and the calculator below is the arithmetic.
Four reasons San Diego homeowners rewrite the mortgage.
The purpose of a refinance decides its shape. The four cards below take the common San Diego 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.
Lower the monthly payment
When the goal is a smaller payment, the file is tested on the break-even and on the term reset. Rolling the costs into the loan raises the balance; restarting the term spreads it across more years; the calculator shows what the San Diego owner actually saves after both. The streamline and the IRRRL test the benefit formally; the conventional refinance leaves it to the arithmetic.
Fold in a purchase-money second lien
The agencies draw the line at the purchase. A purchase-money second rolls into a limited cash-out refinance; a non-purchase-money second or a HELOC does not, however little was drawn. The distinction decides the program, the leverage, and the price, so a San Diego loan officer confirms the origin of the second lien before sizing the file.
Get rid of mortgage insurance
Rising values in San Diego 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 San Diego home before requesting a quote.
Start with what you know about the San Diego loan: the balance, the rate, the years left, and the costs you expect. Then pick the program and the new term. The result shows the new payment, the monthly change, and the months to recover the costs. It also shows the interest over the new term against what the current loan still owes. Every field is editable and nothing here is a quote.

Illustrative starting assumptions: a $905,000 home value near San Diego’s median owner-occupied value, a $634,000 current balance, a current rate and remaining term you enter, closing costs seeded at $12,500 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.
Which refinance fits depends on the loan being replaced, the balance, and what the owner wants from the new loan. The cards compare the conventional route, the government streamlines, and the jumbo lanes on the same San Diego questions: the appraisal, the leverage, the insurance, the fee, and the review.
Conventional, streamline, or jumbo.
Conventional is the refinance for most San Diego homeowners: an appraisal, the agencies’ leverage cap, a full credit and income review, and mortgage insurance only above the published line. It fits a lower payment, a shorter term, an FHA exit, an ARM converted to fixed, or a borrower removed, and it is the only one of the four that applies to any loan being replaced. See the conventional loan program.
For a San Diego owner whose loan is already FHA or VA, the streamline or the IRRRL is the lightest file on this page: no appraisal in most cases, a limited review, a benefit the new loan must deliver, and the agency’s own seasoning and payment-history rules on the loan being replaced. The FHA premium stays; the VA fee is financed or waived. Neither reaches a borrower whose loan is conventional. See the FHA and VA programs.
Above the conforming limit the agencies step aside and the wholesale jumbo lanes take over: a higher score floor, leverage set by the lane, reserves measured in months of payments, and a second appraisal on the largest loans. The rate-and-term jumbo refinance fits a San Diego owner whose balance the conforming limit cannot hold, on a fixed, adjustable, or interest-only structure. 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 San Diego scenario review.
Most of what a refinance needs is already in a San Diego homeowner’s files: the mortgage statement, the pay stubs, the insurance declaration, the tax bill. This list says what to gather and why each item matters to the file.
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.
A handful of details decide whether a San Diego refinance closes as planned, closes on different terms, or should not close at all. These are the ones that come up most.
Use these checks to keep the San Diego file clean and fundable.
The order that saves wasted fees: first the break-even and the term comparison on your own figures, then the program the loan being replaced allows, then the value question, and only then the appraisal and the application.
- Run the break-even: Costs rolled into the loan lengthen the break-even slightly; costs paid at closing shorten it.
- Weigh the reset: A longer term lowers the payment and can raise the total interest.
- Check the project: Conventional and jumbo refinances review the condominium project.
The costs are recovered only through the saving
Closing costs are paid from the loan or at the table, and the only thing that earns them back is the monthly saving. Divide the costs by the saving and the result is the number of months the San Diego owner must keep the new loan to come out even; an owner planning to sell or refinance again before then is paying for a loan they will not use.
The term starts over unless you choose a shorter one
Two refinances with the same rate can produce opposite results: one lengthens the loan and lowers the payment, the other shortens it and lowers the total interest. Which is right depends on what the San Diego owner needs each month and how long they will hold the home. The calculator’s interest comparison is where that decision is made.
Condominiums add the project review on the conventional and jumbo routes
The unit is appraised and the project is reviewed, and either can slow a conventional condominium refinance. The dues enter the ratio, the master insurance must meet the agencies’ standard, and a project that fails the review moves the file to a portfolio program on other terms. A streamline or an IRRRL on an existing government loan skips the review.
Removing or adding a borrower rewrites the note
Adding a borrower whose income helps the ratio, or removing one who no longer lives in the San Diego home, is done by rewriting the note. The file is qualified on the borrowers who remain, the program follows the loan being replaced, and no cash moves through the loan unless the file becomes a cash-out, with that program’s leverage and rules.
The streamlines require a net tangible benefit
An FHA streamline and a VA IRRRL cannot close unless the new loan delivers a net tangible benefit as the agency defines it, a lower payment, a fixed rate in place of an adjustable one, or another listed benefit, measured against the loan being replaced. VA adds a recoupment test where the new loan does not exceed the payoff: the fees and costs must be recovered within its window.
From a San Diego scenario review to a new first payment.
From the first conversation to the new first payment, a San Diego 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
The review settles the shape of a San Diego file: which program, which term, whether the saving recovers the costs, whether the term reset gives the saving back, and whether the value supports the plan. The answer is written terms and a break-even figure, or a plain recommendation not to refinance yet.
Application and automated finding
On a conventional or jumbo file the automated finding decides what the underwriter will see: income documents, assets, the appraisal type, and the ratio ceiling. On a streamline or an IRRRL the agency’s limited review applies. The San Diego owner gathers what the finding asks for and nothing more.
Appraisal and underwriting
Value first, then verification. On a conventional or jumbo refinance the appraisal is the one input the San Diego 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.
Why San Diego owners bring a refinance to a brokerage: the programs are compared side by side, conventional, the streamlines, and jumbo, on the same numbers; the file is placed with the wholesale program that fits it rather than the only one a lender sells; and the answer, including the answer not to refinance, is given in writing first.
The break-even, run before anything else
Every Lendmire refinance review begins with the costs against the saving and the interest over the new term against what remains on the old loan. A San Diego owner whose numbers do not work hears so in the first conversation, in writing, and spends nothing finding out.
Shopped across wholesale programs
The conventional route, the streamlines, and the jumbo lanes are compared side by side on the owner’s balance, value, and goal, and the program that delivers the saving at the lowest cost is the one the file goes to. The lender is never the only option because the brokerage is not the lender.
Terms in writing, before any fee
An appraisal fee on a refinance that cannot pay for itself is money wasted, so the written terms come first and the appraisal second. The owner sees the new loan, the payment, the saving, and the break-even before any fee is charged.

San Diego refinance FAQs
Before you request a San Diego 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?
Rate-and-term means the loan’s terms change and the balance does not, apart from the costs rolled in. A cash-out means the balance grows and the difference is paid to the borrower. The agencies treat them as different transactions with different leverage and different prices, and so does every program on this page.
When does refinancing actually make sense?
A San Diego refinance makes sense when the break-even is short relative to how long you will hold the loan, or when the goal is not a saving at all, such as leaving FHA insurance behind by moving to a conventional loan, fixing a rate, or shortening the term. It does not make sense when the saving is small against the costs, when you will sell before the break-even, or when a longer term gives back the saving in interest.
What does a refinance cost to close?
Every refinance has costs, and a refinance advertised without them has moved them into the rate or the balance. Lendmire states them in the written terms before the appraisal, and the calculator on this page treats your estimate of them honestly, recovered only through the saving and never assumed away.
Can I get rid of mortgage insurance by refinancing?
For FHA borrowers, yes, by refinancing conventionally at or below the line; the streamline keeps the premium. For conventional borrowers, often without refinancing, by asking the servicer to cancel at the published line; a refinance helps when rising values would clear the line on a new appraisal before the balance would on its own.
What is an FHA streamline, and who can use it?
Only FHA-to-FHA. The streamline cannot refinance a conventional or VA loan, and it cannot remove FHA insurance; it can lower the payment or fix an adjustable rate with less documentation than any other refinance on this page, provided the new loan passes HUD’s benefit test and the old loan is seasoned with the required payment history.
Will I need an appraisal, and what if it comes in low?
Yes on the conventional and jumbo routes, no on the government streamlines. Improvements count to the extent the market pays for them, not what they cost. If the figure disappoints, the loan is resized to the cap at that value, the insurance line is re-checked, or the file waits for the market.
Does my state treat a refinance differently?
Mostly no: a rate-and-term refinance follows the program’s rules wherever the home sits, and the figures in the snapshot apply in every state Lendmire serves. A few states add their own conditions to particular loans, most often to loans secured by a homestead or to the refinance of an existing home-equity loan, and where that is the case the state guide on this site carries the detail. A Lendmire loan officer confirms any state rule before the file is sized.
Can I refinance to remove my ex-spouse, or to add someone, to the mortgage?
Yes. A name comes off a mortgage only when the loan is rewritten, so a refinance is the ordinary route after a divorce or a change in the household: the remaining borrower qualifies alone on income, credit, and the ratio, and the title is conformed at closing. Adding a spouse or a family member whose income helps the ratio works the same way. If the departing owner is paid their equity through the new loan, the file becomes a cash-out or a special-purpose refinance, which is a different program.
Why is there a waiting period after I sign?
Because the law requires it on a principal residence. The San Diego owner signs, the period runs, the old loan is paid off, and the new one funds; the first payment follows funding. It is also why a refinance appears to skip a month: the payment is not skipped, the interest for that month is paid at closing.
Can I pay off a second mortgage or a HELOC with a rate-and-term refinance?
The agencies draw the line at the purchase date. Two loans taken to buy the home can become one through a rate-and-term refinance; a line of credit taken later cannot, however little was drawn. The origin of the lien decides the program, the leverage, and the cost.
The San Diego refinance file, shopped across programs and explained plainly.
Enter your San Diego figures above, then ask for a review; the program, the cap, the insurance line, the benefit test, and the break-even are checked against the agencies’ rules and the wholesale overlays, and what comes back is a written set of terms, not an estimate, and a plain recommendation if the refinance does not pay.
