FHA Loans in San Diego: Limits, MIP, and When They Beat VA and Conventional

Key takeaways

• FHA requires as little as 3.5% down with a credit score of 580 or higher, and its underwriting is more forgiving of past credit issues than conventional financing.
• FHA charges mortgage insurance regardless of down payment: a 1.75% upfront premium (UFMIP), financed into the loan, plus an annual premium billed monthly as part of your payment.
• At less than 10% down — nearly every FHA purchase — that annual premium runs for the life of the loan, not just a set number of years. That is the single biggest long-run cost against VA or conventional financing.
• San Diego County's 2026 FHA loan limit is $1,104,000, matching the county's conforming loan limit and up from $1,077,550 in 2025.
• In a worked $850,000 example below, FHA's estimated monthly total lands between VA (cheaper, but only if you have earned eligibility) and 20%-down conventional (cheaper still, but only if you have $170,000 in cash).
• FHA's flexible-qualifying rules extend past the down payment: condo approval (project-wide or single-unit), the 203(k) renovation loan, gift funds, and non-occupant co-borrowers all give FHA buyers options VA and conventional financing restrict more tightly.

How the FHA loan works

FHA does not lend money itself. It insures loans made by approved private lenders, which is what lets those lenders accept more risk than they otherwise would. The program's core rules, per HUD's Single Family Housing Policy Handbook 4000.1:

• 3.5% minimum down payment for borrowers with a credit score of 580 or higher. Borrowers with a score between 500 and 579 can still qualify, but the minimum down payment rises to 10%.
• More flexible credit qualifying than conventional loans. FHA underwriting allows higher debt-to-income ratios with compensating factors and a shorter waiting period after bankruptcy or foreclosure.
• Owner-occupancy is required. FHA loans finance a primary residence only. A property with up to four units qualifies if the borrower occupies one of them, and rental income from the other units can help with qualifying, subject to lender documentation rules.
• A property condition standard applies. The home must meet HUD's Minimum Property Standards, checked at appraisal — safety, soundness, and sanitary conditions.

None of that is unique to San Diego. What is worth checking locally is whether the math still works once FHA's mortgage insurance is layered on top of the county's above-national-average prices — which is the rest of this guide.

The cost that defines FHA: mortgage insurance

Every FHA loan carries mortgage insurance, in two parts, per HUD Handbook 4000.1 and the FHA annual MIP schedule (Mortgagee Letter 2023-05):

Upfront Mortgage Insurance Premium (UFMIP): 1.75% of the base loan amount, charged once. It is normally financed into the loan rather than paid in cash at closing, which is why an FHA loan balance is always somewhat larger than the purchase price minus the down payment.

Annual MIP, billed monthly as part of the payment, at a rate that depends on the loan's size and its loan-to-value (LTV) ratio. For the 30-year (or any term longer than 15 years) loans most buyers use:

San Diego County's above-national-average prices routinely push FHA loans past the $726,200 threshold, and a 3.5% down payment puts LTV at 96.5% — above 95%. Together, that lands a large share of San Diego FHA borrowers on the 0.75% annual MIP tier, the most expensive one on the schedule.

The detail that matters most: when the down payment is below 10%, annual MIP runs for the life of the loan. Only borrowers who put down 10% or more get MIP cancellation, and even then it takes 11 years, per HUD's MIP cancellation rules in the same handbook and mortgagee letter. At FHA's minimum 3.5% down payment, there is no automatic cancellation point at all — the only way off is to refinance out of FHA once there is enough equity. That is fundamentally different from conventional private mortgage insurance, which by law cancels once the loan amortizes down to 78% LTV, and from VA loans, which never charge monthly mortgage insurance at all.

San Diego's 2026 FHA loan limit

FHA sets its loan limits county by county, and in high-cost areas like San Diego the FHA “high-balance” limit is set equal to the area's conforming loan limit. For 2026, San Diego County's limit is $1,104,000, up from $1,077,550 in 2025, per HUD's FHA mortgage limits schedule and the Federal Housing Finance Agency's (FHFA) 2026 conforming loan limit values. A loan above that ceiling needs a jumbo product; FHA does not insure it. At San Diego's typical purchase prices, most buyers stay well under the limit even with a low down payment, since the limit governs the loan amount, not the purchase price.

FHA vs. VA vs. conventional: a worked comparison

Take an $850,000 San Diego purchase — comfortably under the county's $1,104,000 limit, so all three programs apply cleanly. The figures below use each program's own rules and this site's fallback rate assumptions (conventional 6.50%, FHA 6.25%, VA 6.15%):

These are illustrative estimates from public program rules and this site's fallback rates, not a lender quote. Your actual rate, closing costs, and credit profile will change the real numbers.

When FHA is the right call. FHA earns its place when a buyer's credit score sits below what conventional financing wants, when recent derogatory credit would get a conventional or VA application declined, or when 3.5% down is genuinely the most cash available. FHA's flexible qualifying is a real feature, not a consolation prize.

When VA beats FHA. If you have earned VA eligibility, the VA program in this example comes out $370/month cheaper than FHA (see the VA loan guide for the full breakdown) — VA charges no monthly mortgage insurance at all, and a veteran with a service-connected disability rating pays no funding fee either. There is essentially no scenario where an eligible, qualifying buyer should choose FHA over VA on cost alone.

When conventional beats FHA. At 20% down, conventional has no monthly mortgage insurance and the lowest payment of the three — but that is a function of the much larger cash requirement, not a cheaper structure. Conventional also allows down payments as low as 3-5% with private mortgage insurance that, unlike FHA's, cancels at 78% LTV rather than running for the life of the loan. A borrower who can qualify for low-down conventional financing and expects to build equity within a decade will generally pay less over time than the same buyer on FHA.

Condos, renovation loans, and other FHA specifics

A few FHA rules worth knowing beyond the basic down payment and mortgage insurance structure, per HUD Handbook 4000.1 and HUD's program pages:

• Condo project approval. FHA financing on a condo unit generally requires the project itself to be on HUD's approved list, re-certified periodically. Since 2019, HUD also allows Single-Unit Approval, letting an individual unit qualify without the whole project being certified, subject to owner-occupancy ratios and FHA concentration limits. Confirm a specific San Diego project's FHA status before writing an offer — approvals lapse.
• The 203(k) renovation loan. FHA's 203(k) program finances the purchase (or refinance) of a home together with repair or renovation costs, in one loan. The Limited 203(k) covers non-structural repairs up to a set cap with a simplified process; the Standard 203(k) covers structural work and larger budgets and requires a HUD consultant to oversee draws. It's a genuine option on San Diego's older housing stock, where a fixer often sells below market.
• Gift funds. FHA allows the down payment and closing costs to be covered entirely by gift funds from an acceptable donor — family, an employer, a labor union, or a close friend with a clear interest — with a signed gift letter confirming no repayment is expected.
• Non-occupant co-borrowers. FHA permits a non-occupant co-borrower (commonly a parent) to help a borrower qualify by income, subject to family-relationship and loan-to-value conditions — more permissive than conventional in several respects, with no equivalent on a VA loan.

Common questions

What credit score do I need for an FHA loan?

580 or higher qualifies for the 3.5% minimum down payment. A score between 500 and 579 can still qualify, but the down payment requirement rises to 10%.

Does FHA mortgage insurance ever go away?

Only if your down payment was 10% or more, and even then it takes 11 years to cancel. Below 10% down — which covers most FHA borrowers, since the minimum is 3.5% — annual MIP runs for the life of the loan. The practical way off it is refinancing into a conventional loan once you have enough equity.

Is FHA cheaper than VA?

No, not for an eligible veteran. VA charges no monthly mortgage insurance at any down payment; FHA always does. In the worked example above, VA came out $370/month cheaper than FHA despite financing a larger loan.

What is San Diego County's FHA loan limit for 2026?

$1,104,000, matching the county's conforming loan limit and up from $1,077,550 in 2025.

Can I buy a condo with an FHA loan in San Diego?

Yes, if the project is on HUD's approved condo list, or if the specific unit qualifies under HUD's Single-Unit Approval option. Confirm the project's current FHA status before writing an offer, since approvals lapse and require re-certification.

Can someone else help me qualify without living in the home?

Yes. FHA allows a non-occupant co-borrower, typically a parent, to help with income qualifying, subject to relationship and LTV conditions in HUD's handbook.
