FHA is a government-insured loan program designed for buyers who don't quite fit conventional lending boxes. Lower down payments, looser credit requirements, and easier DTI qualifying make it a genuine gateway product. But FHA's mortgage insurance structure — both upfront and monthly, often for the entire loan term — makes it an expensive long-term hold. The right strategy is often to use FHA to get in, then refinance out within 2-5 years.
The Thesis in One Sentence
FHA is the right loan if conventional rejects you or prices you punitively — not as a default low-down-payment option when conventional would also work.
That distinction matters because FHA's loan structure is expensive to hold for the long term. In San Diego, where homes are often kept for a decade or more, the cumulative cost of FHA mortgage insurance can exceed $75,000-$120,000 on a median-priced home. For buyers who qualify for conventional with PMI, that's real money left on the table.
FHA Limits in San Diego (2026)
San Diego County's 2026 FHA loan limit is $1,209,750 for a single-family home — identical to the conforming conventional limit. That's higher than most California counties and reflects San Diego's high-cost-area designation.
Who FHA Is For
- Credit scores between 580 and 660. Below 680, conventional PMI gets expensive fast. FHA prices more consistently.
- Buyers with higher DTI (45-55%). FHA's automated underwriting is more forgiving than conventional's at elevated DTI.
- Recent credit events. FHA allows borrowers 2 years after Chapter 7 bankruptcy and 3 years after foreclosure — faster than conventional.
- Limited reserves. FHA requires fewer months of reserves than conventional for borderline files.
- Buyers planning to refinance within 2-5 years. Use FHA to get in, refi to conventional once you've built equity and improved credit.
- Gift-heavy down payments. FHA allows 100% of the down payment from gifts. Conventional requires some borrower contribution in most scenarios.
Who Should Skip FHA
- Credit scores above 740. Conventional PMI is dramatically cheaper at this tier.
- Buyers competing for contested listings. San Diego sellers often view FHA offers skeptically due to appraisal and property-condition requirements.
- Condo buyers outside FHA-approved projects. The approval list is short in San Diego; most condos aren't on it.
- Forever-home buyers with good credit. Permanent MIP is a permanent tax. Conventional is almost always cheaper over a 10+ year hold.
- Veterans eligible for VA. VA beats FHA on nearly every dimension.
FHA Mortgage Insurance: The Real Cost
The biggest thing non-specialists miss about FHA is that mortgage insurance is structural, not optional, and mostly permanent.
Upfront MIP (UFMIP)
- 1.75% of the loan amount, paid at closing
- Can be financed into the loan (most buyers do this)
- On an $800,000 FHA loan: $14,000 added to your balance
Annual MIP
- 0.55% of the loan balance annually (for 30-year loans with less than 10% down in 2026)
- Paid in monthly installments as part of your mortgage payment
- On an $800,000 FHA loan: $366/month initially
MIP Duration
- Less than 10% down: MIP required for the full 30-year term of the loan
- 10% or more down: MIP drops off after 11 years
- No natural cancellation: Unlike conventional PMI, you can't request cancellation by hitting 80% LTV
- Only way out: Refinance into a conventional loan once you have 20%+ equity
The MIP Math Compounds
On a typical San Diego FHA loan of $800K held for 10 years, you'll pay roughly $42,000 in annual MIP alone — on top of the $14,000 UFMIP. That's $56,000 in insurance premiums over a decade, none of which builds equity. For the same buyer on a conventional loan with PMI that drops off at 80% LTV, the total cost is often under $15,000.
FHA vs Conventional: The Real Comparison
On a $800K San Diego home with 5% down, 680 credit score:
| Metric | FHA Loan | Conventional 95% |
|---|---|---|
| Loan Amount | $772,000 (includes UFMIP) | $760,000 |
| Illustrative Rate | ~6.50% | ~6.875% |
| Monthly P&I | $4,879 | $4,992 |
| Monthly MIP / PMI | $354 | $507 |
| Total Monthly | $5,233 | $5,499 |
| MI Removable? | Only via refinance | Yes, at 80% LTV |
| 5-Year MI Cost | ~$21,240 | ~$20,000 (then drops to $0) |
| 10-Year MI Cost | ~$40,500 | ~$20,000 (none after year 5-6) |
Look at years 5-10. FHA keeps charging MIP. Conventional doesn't. Over a decade, conventional saves $20,000+ on MIP alone even with a higher initial rate.
FHA Strengths
Lower Credit-Score Pricing
FHA prices loans based on LTV, not credit score. A 640-score FHA borrower often gets the same rate as a 740-score FHA borrower. Conventional adds substantial pricing adjustments below 700.
Higher Allowable DTI
FHA's automated underwriting routinely approves DTI up to 55% with compensating factors. Conventional typically caps at 50%.
Streamline Refinance
If you keep your FHA loan, the FHA Streamline Refinance lets you refinance to a lower rate without an appraisal, income verification, or credit re-check. It's the best refi product in the industry for existing FHA borrowers.
Assumability
FHA loans are fully assumable by a qualified buyer — meaning if you lock in a 6.5% loan and rates climb to 9%, a future buyer can take over your loan. This feature has meaningful resale value in rising-rate environments.
FHA Weaknesses
Permanent Mortgage Insurance
Already covered. The biggest structural drawback.
Property Condition Requirements
FHA appraisers check for safety issues — peeling paint, handrails, water heater strapping. In California's older housing stock (Hillcrest, Golden Hill, North Park), this can kill deals or require seller-funded repairs before closing.
Seller Perception
In contested San Diego markets, listing agents often advise sellers against FHA offers. The concern is appraisal risk and the repair-requirement uncertainty. If you're competing with 10 other offers, FHA lowers your win probability.
Condo Approval
FHA only lends on condos in FHA-approved projects. San Diego's approval list excludes the majority of downtown, Mission Valley, and East Village buildings. Individual unit approvals exist but add complexity.
The Bridge Strategy
For many San Diego buyers with mid-600s credit, the smartest use of FHA is as a bridge:
- Year 0: Buy with FHA at 3.5% down. Accept the MIP.
- Years 1-3: Pay on time, rebuild credit, let the home appreciate.
- Year 3-5: Refinance to conventional. With 720+ credit and 20%+ equity, conventional without PMI is typically 0.50+ points cheaper all-in.
- Result: You got into a house you couldn't have bought otherwise, and exited FHA before the MIP cost spiraled.
This strategy has a real weakness: if rates rise or your home doesn't appreciate, the refinance exit may not be available when you want it. Plan for the possibility of being stuck with FHA for longer than expected.
The San Diego Context
FHA accounts for roughly 14% of San Diego County purchase originations, concentrated in South Bay, East County, and parts of Mid-City. Average FHA loan size is $595K — well below the $1.2M limit, reflecting where FHA buyers actually shop.

Common Mistakes
- Taking FHA when conventional would approve you. Ask your lender to run both scenarios. If conventional approves at similar rate, take it.
- Ignoring the MIP in the payment comparison. Compare total monthly cost (P&I + MIP/PMI), not just rate.
- Not planning a refinance exit. If you're taking FHA, know your escape plan: target LTV, credit score goal, and timeline.
- Assuming FHA is "easier." The appraisal is harder, the timeline can be longer, and the documentation requirements are similar.
- Financing the UFMIP without understanding it. You're adding $10K-$20K to your loan balance and paying interest on it for 30 years. It's a cost.
The Bottom Line
FHA is an excellent gateway product for buyers who can't qualify conventionally. It gets you into a house with forgiving underwriting. But the mortgage insurance structure makes it a poor long-term hold, and San Diego's market dynamics (competitive offers, older housing, non-approved condos) add friction.
If you're using FHA, use it deliberately. Know why conventional didn't work for you. Plan the refinance exit. And don't let a loan officer default you into FHA without a conversation about whether conventional would also approve.
