Quick answer: FHA loans in Fairfield require 3.5% down with a 580 credit score, up to the 2026 Solano County FHA limit of $685,400 for a one unit home. On a $600,000 Fairfield home, close to the August 2026 median, that is $21,000 down and an estimated $4,887 a month before homeowners insurance. The City of Fairfield’s own down payment loan is on hold, but eligible first time buyers can still use CalHFA MyHome Assistance.
FHA is built for buyers who have steady income but are still building credit or savings. It allows lower scores and higher debt ratios than most conventional loans, and it welcomes help from family. In Fairfield, where the median home sold for about $600,000 in August 2026, that flexibility is often what turns renting into owning.
As an independent mortgage broker based in Solano County, I shop FHA across many wholesale lenders, because lender minimums and pricing vary more on FHA than most buyers expect. Here is how FHA works on a typical Fairfield purchase.

A $600,000 Fairfield Purchase With FHA
| Step | Amount |
|---|---|
| Purchase price | $600,000 |
| Your down payment (3.5%) | $21,000 |
| Base loan amount | $579,000 |
| Upfront mortgage insurance (1.75%), added to the loan | $10,133 |
| Total loan amount | $589,133 |
| Principal and interest at 7.32% | $4,047 a month |
| Annual mortgage insurance (0.55%) | About $265 a month |
| Property taxes (about 1.15%) | About $575 a month |

FHA rates are often a bit lower than conventional rates for the same buyer, so your real payment may come in under this example. I pull live pricing from several lenders before you write an offer.
Family Can Help With an FHA Loan
FHA is one of the most family friendly loan types. A parent, grandparent, or other relative can give you money for the down payment and closing costs, documented with a simple gift letter. FHA also allows a family member who will not live in the home to sign on as a non occupant co borrower, so their income helps you qualify. For many Fairfield buyers, that is the difference between a 3.5% plan that works and one that does not.
City of Fairfield Programs and the Help Available Now
The City of Fairfield’s Affordable Housing Division lists its Silent Loan Down Payment Assistance Program and its CalHOME Program as on hold until further notice, and says it is out of Mortgage Credit Certificate allocations. You can confirm the latest status with the division at 707-428-7095.
That leaves statewide and lender programs. First time buyers can pair a CalHFA FHA loan with CalHFA MyHome Assistance, a deferred payment junior loan of up to 3.5% of the price or appraised value, which can cover the full FHA down payment. The 2026 CalHFA income limit for Solano County is $246,000, and homebuyer education is required. I also work with other FHA down payment assistance programs through my lender partners. The Fairfield first time buyer guide compares them.
Buying a Duplex or Triplex in Fairfield With FHA
FHA can finance a two to four unit property as long as you live in one unit. Rent from the other units may count toward qualifying, and FHA loan limits are higher for multi unit homes. Three and four unit purchases also require cash reserves and a self sufficiency test on the rents, so I confirm the exact Solano County limit and the numbers for the specific building before you make an offer.
FHA Requirements
- Credit score: 580 for 3.5% down, or 500 to 579 with 10% down. Many lenders set their own floor near 600 to 620, so shopping lenders matters.
- Debt to income: approvals into the high 40s or low 50s are possible with strong compensating factors.
- Occupancy: must be your primary residence. FHA does not finance second homes or rentals, which is where a conventional loan in Fairfield fits.
- Property: must pass FHA minimum property standards at appraisal. Condos must be in an FHA approved project.
FHA or Something Else?
If your credit score is under about 680 or your debt ratio is high, FHA often wins. With stronger credit, conventional usually costs less because its mortgage insurance is lower and removable. If you have served, including at Travis Air Force Base, a VA loan in Fairfield needs no down payment and no monthly mortgage insurance and is usually the first one to price.
Frequently Asked Questions
What is the FHA loan limit in Fairfield for 2026?
Fairfield is in Solano County, where HUD set the 2026 FHA limit for a one unit home at $685,400. With 3.5% down, that supports a purchase price up to about $710,000. Limits are higher for two to four unit properties.
What is the monthly payment on a $600,000 Fairfield home with FHA?
With 3.5% down at the October 22, 2026 Freddie Mac average of 7.32%, principal and interest is about $4,047 on a total loan of $589,133, which includes the financed upfront premium. Add about $265 for annual mortgage insurance and about $575 for property taxes, for roughly $4,887 a month before homeowners insurance.
Is the City of Fairfield down payment assistance loan available right now?
Not at the moment. The City of Fairfield lists its Silent Loan Down Payment Assistance Program and its CalHOME Program as on hold until further notice. FHA buyers can still use CalHFA MyHome Assistance, which can cover up to 3.5% of the price for eligible first time buyers.
Can a parent help me qualify for an FHA loan in Fairfield?
Yes, in two ways. FHA allows gift funds from family for the down payment and closing costs, and it allows a family member who will not live in the home to join the loan as a non occupant co borrower so their income counts toward qualifying.
Can I buy a duplex in Fairfield with an FHA loan?
Yes, as long as you live in one of the units. FHA finances one to four unit properties for owner occupants, and the rent from the other unit may help you qualify. Three and four unit homes also need cash reserves and must pass a rental income test, so I review those early.
How long does FHA mortgage insurance last?
With less than 10% down, the annual premium stays for the life of the loan. With 10% or more down, it ends after 11 years. Many owners refinance into a conventional loan once they reach about 20% equity to drop it sooner.
Examples are illustrations only, not a loan offer or rate quote. Rates change daily and your actual terms depend on your credit, income, property, and the lender. Figures above use the Freddie Mac 30 year fixed average of 7.32% from October 22, 2026.
