FHA loans in San Diego: 3.5% down and the 2026 limit
Quick answer: FHA still lets many San Diego buyers purchase with 3.5% down. For 2026, the 1-unit high-cost county figure we use is $1,104,000. The tradeoff is mortgage insurance. Price FHA against conventional on the full monthly number, not the down payment alone.
FHA loans are still one of the most useful tools for San Diego buyers who have solid income but less cash for a large down payment. They are not only for first-time buyers, and they are not automatically the cheapest option. They are a fit when 3.5% down and the 2026 $1,104,000 county limit match the house you can actually close.
2026 San Diego County FHA limits
HUD publishes county FHA forward limits separately from conventional. In high-cost counties they often match the FHFA high-cost figure. That 1-unit San Diego County number for 2026 is $1,104,000. The table below is copied from our San Diego conforming loan limits 2026 post. Confirm the current HUD county table for the property type before you write an offer.
| Property | 2026 San Diego County high-cost limit |
|---|---|
| 1-unit (house, condo, townhome) | $1,104,000 |
| 2-unit | $1,413,350 |
| 3-unit | $1,708,400 |
| 4-unit | $2,123,100 |
3.5% down is calculated from the purchase price. The $1,104,000 figure is a loan-amount cap, not a list-price cap. If the loan (including financed upfront MIP) would clear that line, FHA is not the path unless the price or down payment changes. I am not inventing a max-purchase sticker here. We run that math on your contract price. The dedicated 2026 FHA loan limits table for San Diego County is on FHA loan limits San Diego 2026.
What an FHA loan is designed to do
FHA financing is backed by the Federal Housing Administration. That backing lets many buyers put 3.5% down and still qualify when credit or cash-to-close is tighter than a conventional loan prefers.
In practical terms, FHA can help you compete in San Diego when you need a lower entry point without waiting years to save 20%.
Down payment and mortgage insurance
FHA typically allows 3.5% down. The tradeoff is mortgage insurance. You will want a clear monthly number that includes principal, interest, taxes, insurance, and FHA MIP.
Do not compare FHA to conventional on rate alone. Compare total monthly cost and how long you expect to keep the loan. The full MIP vs PMI explainer is on FHA MIP vs conventional PMI. Snapshot from that post:
| Piece | Typical FHA purchase (from MIP post) |
|---|---|
| Upfront MIP | 1.75% of the base loan amount, usually financed |
| Annual MIP | Often 0.55% of the base loan on many 30-year files since HUD's 2023 cut. Confirm the factor on your Loan Estimate. |
| Duration, under 10% down | Annual MIP typically lasts for the life of the loan |
| Duration, 10% or more down | Annual MIP typically ends after 11 years if the loan is current |
On the MIP post's $850,000 San Diego example, 3.5% down is $29,750 and the base loan is $820,250. That is a cash-to-close win. It is not automatically a payment win once financed UFMIP and life-of-loan MIP are in the number.
When FHA is often a strong fit
- You have reliable income but limited liquid cash for down payment
- Your credit is acceptable for FHA but not ideal for the best conventional pricing
- You want to buy sooner rather than wait to stockpile a bigger down payment
When conventional may be better
- You can put more down and qualify cleanly conventional
- You want a clearer path to removing mortgage insurance with equity
- The total cost over your expected timeline favors conventional
Local process still matters
In San Diego, the loan program is only one piece. Property condition, HOA details on condos, and clean documentation still decide whether your offer and underwriting stay smooth.
If you are weighing FHA versus conventional, get both paths priced for your actual credit, down payment, and target payment. That is the only way to decide with real numbers.
