Current conventional guidelines, updated from one source.
The block below is the conforming rulebook reduced to the figures that decide a file, read from Lendmire’s single guideline source and refreshed on this page when the agencies or the wholesale overlays change: the down payment by buyer, the credit floor, the mortgage insurance threshold and its cancellation points, and the ratio maximums.
First-time buyer; 5% standard; 97% loan-to-value at the top
The agencies set the floor at 3% down for a first-time buyer and 5% for a repeat buyer, on a principal residence; the whole down payment may be a gift from a relative on a one-unit home, and twenty percent down removes mortgage insurance from the payment entirely.
Priced on the score; no agency minimum with an automated approval
The wholesale programs behind these pages start at a 620 decision score. The agencies themselves set no minimum for an automated approval and ask for 620 on a manually underwritten fixed-rate loan and 640 on an adjustable; the score prices the loan and the insurance more than it gates them.
Required above 80% LTV; removed at 80% by request, 78% automatically
Above 80% loan-to-value the loan carries private mortgage insurance; at or below it, none. The insurance cancels on request at 80% of the original value and automatically at 78%, which is the single largest structural difference from FHA, whose premium at full leverage lasts for the term.
With an automated approval; 36% to 45% on a manual file
Total debt against gross income, up to 50% on an automated approval and 36% to 45% on a manual file. The housing payment counted includes the mortgage insurance while it applies, which is why cancellation changes the ratio as well as the payment.
| Purpose | Occupancy and program | Maximum LTV |
|---|---|---|
| Purchase | One-unit principal residence, first-time buyer (fixed rate) | 97% |
| Purchase | One-unit principal residence, standard | 95% |
| Purchase | HomeReady / Home Possible (income limits apply) | 97% |
| Purchase | Two- to four-unit principal residence | 95% |
| Purchase | Second home | 90% |
| Purchase | Investment property, one unit | 85% |
| Purchase | Investment property, two to four units | 75% |
| Refinance | Limited cash-out (rate-and-term), one-unit principal residence | 95% |
| Refinance | Cash-out, one-unit principal residence | 80% |
| Refinance | Cash-out, two to four units, second home or investment | 75% |
| Combined LTV | Maximum contribution |
|---|---|
| above 90 percent | 3% of the sales price |
| 75.01 to 90 percent | 6% of the sales price |
| 75 percent or less | 9% of the sales price |
| investment property (any) | 2% of the sales price |
| Event | Waiting period |
|---|---|
| Chapter 7 or 11 bankruptcy | four years from discharge or dismissal (two years with documented extenuating circumstances) |
| Chapter 13 bankruptcy | two years from discharge; four years from dismissal (two with extenuating circumstances) |
| Multiple bankruptcy filings | five years when more than one filing within the past seven years |
| Foreclosure | seven years (three with extenuating circumstances, then limited to a principal residence or second home at 90 percent LTV, purchase or limited cash-out) |
| Deed-in-lieu, short sale or mortgage charge-off | four years (two with extenuating circumstances) |
Mortgage insurance: Fannie Mae reports that private mortgage insurance typically ranged from 0.58%–1.86% of the loan amount a year; the premium on a specific loan is priced by the insurer on the score, the leverage, and the coverage, and is never quoted here. Gifts from relatives may fund the entire down payment on a one-unit principal residence. HomeReady and Home Possible lend to 97% with income at or below 80% of the area median; HomeOne lends to the same leverage with a first-time buyer and no income limit.
Current conventional snapshot · updated October 1, 2026 · principal residences occupied within sixty days, second homes, and one- to four-unit investment properties · conforming limits apply by county and are confirmed by a Lendmire loan officer · above the limit, see the jumbo program · no prepayment penalty · Lendmire is a broker, never the lender.
Not a commitment to lend, not an offer of credit, not a quote. The figures shown are current conforming program parameters and wholesale overlays that change without notice and apply only after full underwriting of the borrower and the property; the mortgage insurance range is Fannie Mae’s published typical range and the premium on any loan is set by the insurer. Conforming loan limits apply by county. Lendmire is a mortgage broker licensed in sixteen states for consumer mortgages, never the lender. NMLS #2371349.
What a conventional loan is — and how the file is qualified.
Every San Francisco conventional file is read by an automated underwriting system against the agencies’ guides. The system does not change the rules below; it applies them: how much leverage the occupancy allows, how the score is read, when mortgage insurance attaches and ends, and what the ratios and reserves must show.
For the program overview, see Lendmire’s conventional loan program, or the statewide guide at Conventional Loans in California; for the mortgage insurance cancellation rules, see the CFPB.
Leverage by occupancy and buyer
The agencies lend most on a home the borrower lives in and less as the occupancy changes: a one-unit principal residence reaches the top leverage, with the first-time buyer’s minimum the lowest down payment in the program; two- to four-unit homes, second homes, and investment properties step down from there, as the table in the snapshot shows for a San Francisco buyer.
Credit scores and automated underwriting
A derogatory event does not end eligibility; it starts a clock. Bankruptcies, foreclosures, short sales, and deed-in-lieu transfers each carry a waiting period in the agencies’ guides, shortened by documented extenuating circumstances, and the snapshot shows each one for a San Francisco buyer planning the timing.
Mortgage insurance that cancels
Above the leverage threshold a private insurer covers the lender’s top-slice risk, and the borrower pays for it in the monthly payment. The premium is priced on the score and the leverage, which is why two San Francisco buyers at the same price can pay very different amounts, and it is temporary: cancellable at the request point and ended automatically at the termination point on the original value.
Ratios, reserves, and the DU finding
Total debt-to-income is the ratio that counts: the full housing payment, insurance included, plus every monthly obligation, against gross income. Automated approvals reach the higher ceiling in the snapshot; manual files are held to the lower pair, with the higher of the two needing the matrix’s credit and reserve criteria.
Every input below is yours: the San Francisco price, the down payment, the buyer type, the term, the rate, the insurance estimate, and the escrows. The thresholds and the ratio ceiling come from the program; the payment, the insurance, and the cancellation month follow from the arithmetic.
Where San Francisco buyers borrow — and how a conforming loan fits.
Conventional loans are sized against a local market, and these are San Francisco’s numbers from the U.S. Census Bureau: how many households own, what a typical home is worth, and what households earn. Together they set the scale of a typical down payment, loan, and insurance premium.
Market context only. Higher values mean a larger down payment in dollars and a larger insurance premium; lower values mean a payment that leaves more room under the ratio ceiling. The percentages do not move; what they amount to does.
Data sources: U.S. Census Bureau — ACS 5-Year (2024) housing and population estimates, including tenure, home values, gross rents, and household income.
Distinct San Francisco neighborhoods, distinct conventional files.
No single conventional file describes San Francisco. The neighborhoods below differ in housing stock, price, occupancy mix, and the appraisal questions they raise, and each one shapes how a conforming loan is put together.
Investor and second-home purchases
An investor buying a San Francisco unit to rent uses the conventional program at the investment leverage, documents the rent the agencies allow, and shows reserves for every financed property; the agencies cap how many such loans one borrower may carry. The median owner-occupied home value in San Francisco runs near $1,394,500 on the latest Census estimate.
Two-to-four-unit homes
Owner occupancy of one unit sets the leverage on a San Francisco multi-unit conventional loan; without it, the property is an investment purchase at the lower investment leverage. The appraisal reads every unit and the rents. On a home at San Francisco’s median value, the first-time buyer’s minimum down payment comes to about $41,800 and the standard minimum to about $69,700 — before closing costs, and before the mortgage insurance that comes with either.
Established close-in neighborhoods
Renovated and unrenovated homes sit side by side in San Francisco’s established neighborhoods, and the appraisal values each on comparable sales. The leverage, the insurance, and the ratio do not change with the age of the house. Roughly 139,057 San Francisco households own their homes on the latest Census estimate — 38% of all households, the pool a conventional purchase joins.
Condominiums and townhomes
A San Francisco condominium near the job is a conventional file with the project review added. Established projects usually pass; new or investor-heavy ones draw questions, and a project that fails goes to a portfolio lender on different terms. About 62% of San Francisco’s households rent — roughly 224,913 renter households on the latest Census estimate.
Newer infill and recent construction
New rows and recent infill in San Francisco tend to appraise cleanly, which moves the question to the loan amount: a contract near the conforming limit is confirmed against the county figure before the offer, and a loan above it needs a larger down payment or the jumbo program. Median household income in San Francisco sits near $140,970 on the latest Census estimate.
Higher-value homes
A high-value San Francisco purchase can still be a conforming loan when the loan amount fits under the county limit, and a high-cost county’s higher range extends that reach; above it, the jumbo program takes the file with its own leverage and reserves. San Francisco counts a population near 830K within the San Francisco-Oakland-Fremont, CA area.
What the program accepts is the same everywhere in San Francisco: houses, warrantable condominiums, planned developments, manufactured homes that meet the agencies’ rules, two- to four-unit homes, second homes, and investment property, each at its own leverage. What it declines is the non-warrantable project and the loan above the conforming limit, which belong to other programs.
Four ways San Francisco buyers put a conforming loan to work.
A good use of a conventional loan is one its shape fits: a decent score, a down payment of any size from the minimum up, an occupancy the agencies allow, and a loan inside the conforming limit. Four common San Francisco uses follow.
Buy with twenty percent down and no insurance
The move-up San Francisco buyer selling one home and bringing twenty percent to the next usually lands here: no mortgage insurance, the strongest cost tier the score earns, and a loan the automated system approves on the equity brought forward.
Buy an investment property
The rental purchase is inside the conventional program at a lower leverage than a principal residence: a San Francisco buyer uses the agencies’ rules for counting rental income, shows reserves for every property financed, and accepts loan-level adjustments that reflect the occupancy.
Buy a first home at the first-time-buyer minimum
For a San Francisco first purchase, the conventional route pairs the agencies’ lowest down payment with insurance that cancels and no upfront premium; the file is qualified on the score, the ratio, the reserves, and the automated finding, and a family gift may fund the whole down payment.
Buy a condominium in a warrantable project
The condominium file adds the project review to the house file. Once a San Francisco project clears it, the first-time buyer’s minimum, the insurance rules, and the ratio ceiling are exactly what they would be on a single-family home.
Estimate the payment on a San Francisco price before requesting a quote.
The program’s own math on your San Francisco inputs: price less the down payment, amortized at the benchmark, with the insurance estimate added while the leverage is above the threshold and the escrows added throughout. The actual rate, premium, payment, and costs come in writing from a licensed loan officer.
San Francisco conventional payment estimate
Defaults describe San Francisco, not your purchase: put in the real price, the real down payment, and the real escrows.
Editable benchmark: 7.03% as of September 24, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $750,000 price near San Francisco’s median owner-occupied home value, the first-time buyer’s minimum down payment, a thirty-year term at the current Freddie Mac benchmark, mortgage insurance at the low end of Fannie Mae’s published range, 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 rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a conventional loan quote; your rate is set by the lender at lock. The mortgage insurance figure is an editable estimate seeded from Fannie Mae’s published typical range, not a premium quote; the insurer prices the actual premium, and the cancellation month assumes scheduled payments with no extra principal and no change in value. Taxes, insurance and dues are editable estimates; closing costs are not included. Conforming loan limits apply by county. Licensed in sixteen states for consumer mortgages.
Same buyer, three very different closings.
The alternatives put the conventional loan’s cost in perspective: FHA charges a premium every month and an upfront premium at closing, VA charges a one-time fee, conventional charges a premium only until equity arrives. The comparison below is written for a San Francisco buyer weighing all three.
Conventional, FHA, or VA.
Conventional fits the San Francisco buyer with a solid score: the premium is smaller than FHA’s for strong credit and it ends, there is no upfront premium, and twenty percent down removes insurance altogether. A modest score or a thin file is where FHA competes.
FHA’s leverage is high and its credit standard is forgiving, but its insurance is priced by schedule rather than by score and does not cancel on a full-leverage thirty-year loan. A San Francisco buyer comparing the two sees the premium line stay on FHA and disappear on conventional. See Lendmire’s FHA loan program.
VA beats conventional on the principal residence for nearly every eligible borrower; conventional beats VA on everything VA does not touch: second homes, rentals, and buyers without the certificate. The two often sit side by side in one San Francisco household. See Lendmire’s VA loan program.
Where each one fits: conventional for the solid score, the move-up buyer, the second home, and the rental; FHA for the modest score and the small investment; VA for the eligible borrower buying a principal residence. Above the conforming limit, see the jumbo loan program.
What to prepare for a San Francisco scenario review.
The paperwork is the standard mortgage set, with the automated finding deciding how much of it the file actually needs; here is what a San Francisco scenario review typically draws on.
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 underwriting finding, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
What moves a San Francisco file most often: the insurance and its cancellation, the score and the cost it sets, the appraisal, the condominium review, the conforming limit, the ratio and the reserves, the occupancy rule, and the seasoning after a credit event.
Use these checks to keep the San Francisco file clean and fundable.
A San Francisco file that is ready to review has already answered three questions: what leverage and therefore what insurance, what score and therefore what price, and whether the home is inside the agencies’ rules.
- Plan the insurance: the premium is priced on the score and the leverage inside the published range.
- Confirm the score: the lender’s report sets the decision score; multiple borrowers use the average of the median scores.
- Check the limit: ask a loan officer for the current figure in the county.
Mortgage insurance: how much, and until when
The premium on a San Francisco loan can be paid monthly, by the lender in exchange for a different price, as a single premium at closing, or split; the monthly structure cancels under the federal rules, and the others are priced by the lender. The calculator shows the monthly structure and the month the thresholds arrive on scheduled payments.
The score sets the cost
The score does two jobs on a San Francisco file: it feeds the automated assessment alongside the rest of the credit file, and it sets the cost of the loan and the insurance. A buyer close to a cost tier sometimes gains more from a short wait and a paid-down balance than from any other change.
The conforming limit
The limit caps the loan, not the price. A San Francisco buyer shopping above it has two choices, a larger down payment or a jumbo loan, and the better one depends on the score, the reserves, and the cost on each. These pages do not quote the limit because it changes every year.
Waiting periods after a credit event
A documented hardship beyond the borrower’s control, such as a job loss or a medical event, can shorten several of the waiting periods, and the shortened foreclosure period limits the leverage and the occupancy. A San Francisco file inside a waiting period is written later, not now.
Seller contributions and the down payment
Two rules shape the San Francisco contract: the contribution cap, which falls as the leverage rises, and the source rules for the down payment, which allow a full gift on a one-unit principal residence and require a share of the buyer’s own funds on second homes and multi-unit homes above the threshold.
From a San Francisco pre-approval to keys in hand.
A conventional purchase runs in a fixed order: pre-approval through the automated system on the score, the ratio, and the reserves; contract and appraisal or value acceptance; underwriting that verifies what the finding assumed; and closing with the insurance structure set. Here is that order for a San Francisco buyer.
Pre-approval
The first conversation settles the shape: whether the buyer counts as a first-time buyer, what leverage the occupancy allows, how much insurance the down payment carries, and whether conventional is the right program next to FHA and VA for the San Francisco purchase.
Contract and appraisal
With the contract signed, the lender orders the appraisal, or accepts the value the automated system offers where a waiver applies. Seller contributions are checked against the cap for the leverage, and a condominium’s project documents are collected for review before the file moves on.
Underwriting
The underwriter verifies what the automated finding assumed: the income, the assets and reserves, the credit and any seasoning, the occupancy, and the property. A manual file follows the lower ratio pair instead. Conditions are issued, documented, and cleared before the approval is final.
Closing
The San Francisco closing applies the program’s structure: the insurance premium in the payment while it applies, the escrow account, and no upfront premium. The buyer moves in within sixty days on a principal residence, and the servicer tracks the balance toward the cancellation thresholds.
A brokerage that prices the whole market.
Lendmire never lends. It reads a San Francisco file against conventional, FHA, and VA, matches the program to the profile, and keeps the premium, the cost tier, and the conforming limit in front of the buyer before anything is signed.
Several programs, one set of numbers
The comparison printed on this page is run for real on every San Francisco file: conventional with the insurer’s actual premium beside FHA with its premiums beside VA where eligibility exists, and the written terms follow from it.
The insurance explained before the offer
No San Francisco buyer should learn at the closing table what the insurance costs or how long it lasts. The loan officer walks through the premium for the leverage chosen, the month the thresholds arrive on scheduled payments, and the alternative of a larger down payment.
Licensed, consumer-purpose, in writing

San Francisco conventional loan FAQs
The questions below come up on nearly every San Francisco conventional conversation. The answers are general; the figures in the snapshot above are the program’s current parameters.
What is a conventional loan, and who is it for?
A conventional loan is a mortgage written to the rules of Fannie Mae and Freddie Mac so the lender can sell it to them after closing; no government agency insures it, and a private insurer covers the top slice above the leverage threshold. It fits the San Francisco buyer with a solid score, any down payment from the program minimum up, and any occupancy the agencies allow, including second homes and rentals.
How much do I need to put down on a conventional loan in San Francisco?
It depends on who is buying and how the home will be used. A first-time buyer starts at the lowest figure in the snapshot, a repeat buyer slightly higher, and a San Francisco second home or rental higher still. Twenty percent down removes mortgage insurance entirely.
What credit score do I need for a conventional loan?
The snapshot shows the floor. More useful than the number is what sits around it: a seasoned derogatory event is inside the rules after its waiting period, a thin file may need manual underwriting with tighter ratios, and the score drives the insurance premium on a San Francisco loan.
How does private mortgage insurance work, and when does it end?
It is temporary insurance for the lender, paid by the borrower while the loan sits above the threshold. On a San Francisco loan with scheduled payments the calculator shows the month the balance reaches the request point and the automatic one; extra principal or a rise in value, recognized by the servicer, can bring the request point sooner.
What is the conforming loan limit in San Francisco?
There is a county limit, revised annually, and some counties carry a high-balance range above the standard figure. The loan officer confirms the current limit at pre-approval; above it, the jumbo program takes the file.
Can I take cash out with a conventional refinance?
It is available at the cash-out leverage shown in the snapshot, with the occupancy setting the limit and the score setting the price. A San Francisco owner weighs it against a home equity line on the same numbers.
What are HomeReady, Home Possible, and HomeOne?
Agency programs that open the top conventional leverage to buyers who meet their conditions: HomeReady from Fannie Mae and Home Possible from Freddie Mac for borrowers with income at or below the area-median threshold in the snapshot, with reduced insurance coverage and a homeownership course; HomeOne from Freddie Mac for first-time buyers with no income limit. Each is a conventional loan with its own rules on top.
What happens after my San Francisco offer is accepted?
The file moves into appraisal and underwriting, and the calendar is set by the appraisal and the conditions the underwriter adds. No page can promise a date, and this one does not.
Can I get a conventional loan after a bankruptcy or foreclosure?
Each event has its own period counted from a specific date, and the lender confirms it from the documents. Clean credit since the event and a rebuilt score carry weight once the period has run.
What does the appraisal check on a conventional loan?
Value against the contract price, and condition against the lender’s standard of safe, sound, and marketable. Older San Francisco homes draw condition notes more often; most are settled before closing.
From a San Francisco pre-approval to keys in hand.
Begin with a scenario review: the price, the down payment, the score, the income, and the occupancy. A licensed Lendmire loan officer prices the file across the wholesale programs, runs it beside FHA and VA, and puts the terms in writing.
