Current FHA guidelines, updated from one source.
The figures below are the FHA program’s own parameters, read from Lendmire’s centralized guideline source and refreshed on this page as HUD’s rules and the wholesale overlays change: the minimum investment, the decision score for maximum financing, the mortgage insurance premiums, and the qualifying ratios.
Up to 96.5% loan-to-value on a purchase
A 3.5% minimum investment opens a purchase at up to 96.5% loan-to-value; the investment can be the buyer’s own funds, a gift from a family member or other acceptable donor, or approved secondary financing.
Decision score for maximum financing
580 is the decision score for maximum financing, and the floor of the wholesale programs behind these pages; the decision score is the lowest of the borrowers’ middle scores, and a thin or non-traditional credit file can still qualify under manual underwriting.
Plus 0.50%–0.55% a year on most thirty-year loans
1.75% upfront plus 0.50%–0.55% a year on most thirty-year loans is the price of the leverage; larger base loans carry a higher annual tier, fifteen-year loans a lower one, and the calculator applies HUD’s schedule to the figures you enter.
Housing and total debt, manual reference
31/43 is the starting point: the housing payment and the total debt as shares of effective income. Cash reserves, a minimal payment increase, or residual income stretch the ratios tier by tier, up to 40/50 with two factors.
| Decision score | Housing / total | Compensating factors |
|---|---|---|
| 500–579 or no credit score | 31% / 43% | not applicable — ratios may not exceed 31/43 (energy efficient homes 33/45) |
| 580 and above | 31% / 43% | no compensating factors required (energy efficient homes 33/45) |
| 580 and above | 37% / 47% | one of: verified and documented cash reserves; minimal increase in housing payment; residual income |
| 580 and above | 40% / 40% | no discretionary debt |
| 580 and above | 40% / 50% | two of: verified cash reserves; minimal increase in housing payment; significant additional income not reflected in effective income; residual income |
| Base loan | Leverage | Annual premium | Duration |
|---|---|---|---|
| Standard base loan amounts | at or below 90% LTV | 0.50% | 11 years |
| Standard base loan amounts | above 90% to 95% LTV | 0.50% | mortgage term |
| Standard base loan amounts | above 95% LTV | 0.55% | mortgage term |
| Larger base loan amounts | at or below 90% LTV | 0.70% | 11 years |
| Larger base loan amounts | above 90% to 95% LTV | 0.70% | mortgage term |
| Larger base loan amounts | above 95% LTV | 0.75% | mortgage term |
Refinances: rate-and-term to 97.75% loan-to-value on a home occupied for the past year; cash-out to 80% after twelve months of ownership and occupancy; streamline refinances of an existing FHA loan without an appraisal. Sellers and other interested parties may contribute up to 6% of the price toward closing costs; the entire minimum investment may be a gift.

What an FHA loan is — and how the file is qualified.
An FHA file in San Diego is built from four pieces: the minimum required investment, the decision score, the mortgage insurance, and the qualifying ratios. Each has a rule, and each rule has a reason, which the cards below explain.
For the program overview, see Lendmire’s FHA loan program, or the statewide guide at FHA Loans in California.
The minimum required investment
HUD requires the buyer to invest a set share of the lesser of the price and the appraised value; the loan covers the rest. On a San Diego purchase the investment can be the buyer’s own savings, a gift from a family member or another acceptable donor, or approved secondary financing, and closing costs are separate from it.
The decision score sets the leverage
The decision score is the lowest of the borrowers’ middle scores. At the maximum-financing threshold and above, a San Diego buyer reaches the full purchase leverage; HUD allows lower scores at reduced leverage, but the wholesale programs behind these pages start at the threshold, so that is the practical floor.
Two premiums: upfront and annual
Two numbers to know: the upfront premium added to the loan at closing, and the annual premium paid monthly. The schedule in the snapshot shows how the annual premium steps with leverage and loan size, and the calculator applies it to a San Diego price.
Qualifying ratios and compensating factors
Two ratios decide the payment the file supports: the housing payment alone, and the housing payment plus every other monthly obligation, each as a share of effective income. The ladder in the snapshot shows the manual tiers; the calculator shows where a San Diego scenario lands.
The result is an estimate, not a decision: the appraisal may land below the contract price, the lender sets the rate at lock, and the ratios are measured on effective income. What does not change is the program structure the calculator reproduces.
Where San Diego’s first-time and moderate-income buyers shop — and how FHA fits.
The Census figures below are the San Diego backdrop for an FHA loan: ownership, value, and income. They are context for sizing, not inputs to a credit decision, which rests on the appraisal and the file.
Citywide figures provide general market context, not an appraisal or an income calculation. Values and incomes explain why two buyers at the same decision score can see very different files: one buys at the median and qualifies on the base ratios, the other stretches to a higher price and needs a compensating factor.

Distinct San Diego neighborhoods, distinct FHA files.
A loan follows the house. These San Diego submarkets differ in the property types the program accepts, the condition questions the appraisal raises, and the prices a typical buyer carries, which is what the cards below describe.
Historic districts
San Diego’s historic neighborhoods are where FHA appraisals most often return required repairs: older systems, lead-era paint, and deferred maintenance all touch HUD’s property standards. Repairs are completed before closing or escrowed where the program permits. San Diego counts a population near 1.39M within the San Diego-Chula Vista-Carlsbad, CA area.
Higher-value homes
The higher-value San Diego file is a limit question, not an eligibility question. The county limit caps the loan amount, and the buyer either adds investment to fit under it or chooses the conventional route for the whole purchase. About 53% of San Diego’s households rent — roughly 279,312 renter households on the latest Census estimate.
Two-to-four-unit homes
The multi-unit San Diego file is where FHA’s leverage does the most work: a small investment on a two- to four-unit property, the buyer in one unit, and the other units’ rent documented toward the ratios the way HUD allows. Roughly 251,100 San Diego households own their homes on the latest Census estimate — 47% of all households, the pool an FHA purchase joins.
Newer infill and recent construction
Infill rows and newer San Diego construction appraise cleanly under HUD’s standards, and the question there is price: a contract near the county limit needs the limit confirmed before the offer, and a larger investment where the price runs past it. The median owner-occupied home value in San Diego runs near $906,700 on the latest Census estimate.
Established close-in neighborhoods
In San Diego’s established neighborhoods the appraiser’s condition findings matter as much as the value. Buyers who expect required repairs negotiate them into the contract early and keep the file moving. On a home at San Diego’s median value, the FHA minimum investment comes to about $31,700 — the cash the program asks a buyer to bring before closing costs.
Condominiums and townhomes
Condominiums are often the entry point in San Diego, and FHA finances them in approved projects or through single-unit approval. The lender confirms the project’s status before the appraisal, the association’s dues enter the ratios, and the minimum investment is unchanged. Median household income in San Diego sits near $108,077 on the latest Census estimate.
Each submarket has a typical property story, but the appraisal is the one that counts. HUD’s property standards, the occupancy rule, and the ratio ladder are the same on every San Diego file.
Four ways San Diego buyers put an FHA loan to work.
Because FHA insures the lender, it fits the San Diego borrower who has the income for the payment but not the profile a conventional loan asks for. Four examples follow.
Buy a first home with the minimum investment
For a first purchase in San Diego, FHA pairs a small investment with a forgiving score and a ratio ladder that stretches with compensating factors; the file closes on the appraisal, the income, and the decision score.
Buy a condominium in an approved project
An FHA condominium file in San Diego adds one step to the house file: the project review. Approved projects and single-unit approvals both work, dues count in the ratios, and the minimum investment and premiums are unchanged.
Refinance an existing FHA loan
An existing FHA loan in San Diego can be refinanced on its own record: the streamline path skips the appraisal and most of the documentation, and the rate-and-term path with an appraisal reaches higher leverage when cash to close or equity matters.
Buy a small multi-unit home and live in one unit
The multi-unit purchase is where FHA’s leverage does the most work: a San Diego buyer brings the minimum investment on a two- to four-unit property, occupies one unit, and qualifies with the rent from the others counted as HUD allows.
Estimate the FHA payment on a San Diego price before requesting a quote.
This estimator runs the program’s own math on your San Diego inputs: price less the investment, plus the financed premium, amortized at the benchmark rate, with the monthly premium and escrows added. A licensed loan officer provides the actual rate, payment, and costs in writing.

Illustrative starting assumptions: a $600,000 price near San Diego’s median owner-occupied home value (kept where an FHA loan is realistic in most counties), the FHA minimum investment as the down payment, a thirty-year term at the current Freddie Mac benchmark, 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 an FHA loan quote; your rate is set by the lender at lock.

Same buyer, three very different closings.
Before deciding on FHA, it helps to see what it is not: not the only low-down-payment route, not the only forgiving-credit route, and not the cheapest insurance for a strong profile. The comparison below puts the three next to each other for a San Diego buyer.
FHA, conventional with mortgage insurance, or VA.
FHA fits the San Diego buyer whose profile a conventional file would turn away or price heavily: the leverage is high, the score threshold is low, and the premiums do not rise with a weaker score. The cost is insurance that stays for the term at full leverage.
Conventional financing asks for a higher score and prices it, in exchange for insurance that can be cancelled and no upfront premium. The comparison is worth running for any San Diego buyer whose score sits above the agency norms. See Lendmire’s conventional loan program.
A San Diego buyer with VA eligibility rarely needs FHA: the VA loan carries no down payment and no monthly insurance, and the funding fee is the only program cost. FHA is the fallback where entitlement is used up or the property does not fit. See Lendmire’s VA loan program.
Where each one fits: FHA for the small investment and the forgiving score; conventional for the strong score that wants cancellable insurance; VA for the eligible borrower who can skip both the down payment and the insurance.
What to prepare for a San Diego scenario review.
What the lender looks at on a San Diego FHA loan, and what you can gather before the review.
This is a general preparation guide, not a universal checklist. The selected lender may request additional information based on the transaction, the property, the credit profile, and the income picture. Nothing here is legal or tax advice.
Local details that can change the loan.
A few local and structural details change the size of a San Diego FHA loan, or whether the file is eligible at all. The ones that come up most often are below.
Use these checks to keep the San Diego file clean and fundable.
The checklist is short because the program is specific: the score, the premiums, and the property decide most San Diego files before income is even reviewed.
- Confirm the score: the threshold in the snapshot opens maximum financing and the ratio ladder.
- Know the premium: the exit from the premium is a refinance, not an equity threshold.
- Match the occupancy: second homes and rentals are outside the program.
The decision score decides the leverage
The decision score is the lowest middle score among the borrowers, read from the lender’s report; a self-pulled score can land differently. At or above the threshold a San Diego buyer reaches maximum financing; the wholesale programs behind these pages start there.
How long the annual premium runs
Unlike private mortgage insurance, the FHA annual premium does not cancel as the home gains value. On a San Diego full-leverage loan the exit is a refinance; the calculator shows the premium’s rate and duration for the leverage entered.
Occupancy and the non-occupying co-borrower
Second homes and rentals are outside the program. A San Diego buyer who will not live in the home cannot use FHA for it; a family member who will not live there can still co-sign, with full leverage preserved on a one-unit purchase.
Seller contributions and the minimum investment
Two sources, two rules: the minimum investment comes from the buyer or a gift, never the seller; closing costs can come from the seller up to the limit. Structured that way, a San Diego purchase can close with cash to close near the investment alone.
The county loan limit
FHA caps the loan by county, and the cap changes each year. A San Diego purchase above the county limit cannot close as an FHA loan at the program’s leverage; a larger investment brings the loan under the cap, or a conventional loan takes the file.
From a San Diego pre-approval to keys in hand.
The San Diego process is a standard mortgage process with FHA’s checks layered on: the decision score, the property standards, the project approval where it applies, and the premium schedule. Here is what happens at each step and what the buyer does.
Pre-approval
The first conversation settles the shape: where the decision score lands, what the ratios support, whether a gift will cover the investment, and whether FHA is the right program next to conventional and VA for the San Diego purchase.
Contract and appraisal
The appraisal is the FHA step that surprises buyers most: it reports on condition as well as value. Required repairs are negotiated with the seller, and a low value raises the investment; the San Diego contract is adjusted or the file moves on.
Underwriting
An automated approval follows the system’s finding; a manual file follows the ratio ladder. Either way, the San Diego underwriter verifies the income, the assets, the credit history, and the property, and issues the approval with its conditions.
Closing
The San Diego closing applies the program’s structure: the financed upfront premium, the monthly annual premium, and the escrow account. The buyer moves in within two months and keeps the home as a principal residence for at least a year.
A brokerage that matches the program to the buyer.
The value of a brokerage on an FHA loan is comparison and candor: FHA against conventional on the same numbers, the premium’s duration stated plainly, the county limit confirmed before the offer, and the terms in writing.
Three programs, one set of numbers
FHA, conventional, and VA are run on the same San Diego price, score, and income before a recommendation is made. The buyer sees the payment, the insurance, and the cash to close on each, and the choice is made on the figures rather than on habit.
The premium explained before the offer
No San Diego buyer should learn at the closing table that the premium lasts for the term. The loan officer walks through the upfront premium, the annual premium, and the duration for the leverage chosen, and shows the conventional alternative on the same numbers.
Licensed, consumer-purpose, in writing
Lendmire holds the license in the state where the San Diego home sits, provides the disclosures a consumer mortgage requires, and puts the terms in writing. The program figures on this page come from one guideline source built on HUD’s handbook; the terms for a specific file come from the loan officer.

San Diego FHA loan FAQs
What an FHA loan is, how much it takes to buy, what score it needs, what the mortgage insurance costs, and how the county limit works, answered for San Diego buyers.
What is an FHA loan, and who is it for?
FHA is HUD’s insurance program for home loans, not a lender. A San Diego buyer applies through a lender or broker, the lender follows HUD’s rules, and HUD insures the loan. The program is built for first purchases and recovering credit, and it also refinances existing FHA loans.
How much do I need to put down on an FHA loan in San Diego?
The minimum required investment shown in the snapshot, measured on the lesser of the purchase price and the appraised value. It can be the buyer’s own funds, an acceptable gift, or approved secondary financing, and closing costs are separate; a seller may contribute toward those up to the program’s limit.
What credit score do I need for an FHA loan?
Maximum financing opens at the decision score shown in the snapshot, which is the lowest of the borrowers’ middle scores on the lender’s report. HUD’s rules allow lower scores at reduced leverage, but the wholesale programs behind these pages start at the threshold, so that is the working floor in San Diego.
How does FHA mortgage insurance work, and how long do I pay it?
Upfront and annual. The upfront premium is financed; the annual premium is monthly and depends on the term, the leverage, and the loan size. At the minimum investment on a thirty-year loan it stays for the term, which is why many San Diego borrowers plan to refinance into a conventional loan later.
What is the FHA loan limit in San Diego?
Ask a loan officer for the county’s current limit; it changes yearly and by unit count. The limit caps the loan amount, so a San Diego purchase above it is still possible with a larger investment or on a conventional loan.
Can I buy a duplex or fourplex with an FHA loan?
Yes. Occupy one unit, count the others’ rent as HUD allows, and expect a self-sufficiency test on three- and four-unit homes. The county limit is higher for more units.
How does an FHA refinance work?
The streamline is the simplest: no appraisal, limited credit review, a net tangible benefit, and the existing loan’s payment history as the test. Rate-and-term and cash-out refinances take an appraisal and full underwriting.
Should I choose FHA or a conventional loan?
Run both. A modest score and a small down payment usually point to FHA; a strong score points to conventional, where the private insurance is smaller and cancels as equity grows. The comparison is made on the actual payment and the cash to close.
Can I take cash out with an FHA refinance?
Yes, with a year of occupancy and the program’s cash-out leverage. The premiums apply to the new loan, which is why owners with a low-balance first mortgage often compare a home equity line first.
What does an FHA appraisal check?
It checks what the home is worth and whether it is safe, sound, and secure under HUD’s rules. Older San Diego homes draw required repairs more often; most are settled before closing.
