The short version
FHA is a government-backed loan built to help buyers who don't have a big down payment or a spotless credit report. You can put down as little as 3.5%, the credit bar is lower than conventional, and the qualifying is more forgiving if your debt-to-income is a little tight. That's why it's often the first program I look at for a first-time buyer in Santa Rosa or Petaluma.
The trade-off is mortgage insurance. Every FHA loan carries an upfront fee plus a monthly one, and on most FHA loans today that monthly piece never falls off — it stays for the life of the loan unless you refinance out. So FHA is fantastic for getting in the door, and for a lot of buyers the plan is to refinance to conventional later once you've got equity and a stronger file. I'll tell you straight whether FHA is the right first move or whether you're actually close enough to qualify conventional and skip the insurance drag.
What is an FHA loan, and who is it for?
It's a mortgage insured by the Federal Housing Administration. The FHA doesn't lend you the money — a lender does — but the government backs the loan, which lets that lender say yes to buyers they'd turn down on a conventional file. That's the whole point of the program: open the door a little wider.
In practice, here's who it fits. First-time buyers who've got steady income but not 20% saved. People rebuilding credit after a rough patch — a medical thing, a divorce, a couple of late payments a few years back. Buyers whose debt-to-income is on the high side because student loans or a car payment are eating into the math. And it's not first-time-only, despite the reputation — you can use FHA more than once, as long as it's the home you're going to live in. What it isn't is a landlord loan. FHA is owner-occupied, primary-residence financing. You have to move in.
- Owner-occupants only — you have to live in the home, generally within 60 days of closing.
- 3.5% down with a credit score of 580 or higher; 10% down in the 500–579 range.
- Steady, documentable income and a two-year work history the lender can verify.
- The home has to pass an FHA appraisal for safety and condition.
- Not just for first-timers — repeat buyers qualify too, as long as it's their primary residence.
What credit score do I actually need for FHA?
On paper, FHA allows a 580 score for the 3.5%-down option, and technically down to 500 if you can put 10% down. That's the FHA's floor. But here's the part people miss: the individual lender sets its own minimum on top of that, called an overlay, and a lot of them won't touch a file under 600 or 620. So the 580 you read about online and the score the lender in front of you actually wants can be two different numbers.
This is exactly where working with a broker earns its keep. I'm not stuck with one bank's overlay — I can shop your file to lenders whose FHA minimums fit where your score actually sits. I've had buyers get told 'no' by their own bank at a 590, then close an FHA loan through a different lender the same month. And if you're sitting at, say, 570 and close, sometimes a few targeted moves — paying down a card below 30% of its limit, clearing one collection — bump you over the line in a billing cycle or two. Don't assume you're out. Let's look at the real report first.
How much can I borrow? Sonoma County's FHA loan limit.
FHA caps how much you can borrow, and the cap is set county by county based on local home prices. Sonoma County is designated a high-cost area, so our FHA limit runs well above the national floor — for 2026 it's approximately $861,000 for a single-family home, though you should verify the current figure for your scenario since these numbers reset every year.
That limit matters here because Sonoma County isn't cheap. A national FHA floor around the mid-$500Ks wouldn't buy much locally, but the high-cost adjustment gives you real room — enough to make FHA workable on a lot of Santa Rosa, Rohnert Park, and Petaluma homes. If the house you want lands above the FHA ceiling, that's when we look at other routes: a conventional loan, or a jumbo if you're up in the higher price tiers. The limit is a ceiling, not a target — plenty of FHA buyers here are well under it.
- 2026 Sonoma County FHA limit: roughly $861,000 for a single-family home (verify the current number).
- The limit is higher for 2–4 unit properties if you're house-hacking a duplex or triplex you'll live in.
- Above the FHA ceiling, conventional or jumbo financing takes over.
- Limits reset annually and track local home prices, so last year's figure may be stale.
What does FHA mortgage insurance really cost?
This is the piece I make sure every FHA buyer understands before they sign, because it's where the surprises live. FHA charges two mortgage insurance fees. First is the upfront premium — currently 1.75% of the loan amount — which almost always gets rolled into the loan instead of paid in cash. Then there's the annual premium, currently around 0.55% of the balance, split across your twelve monthly payments. On a $500,000 loan that annual piece is roughly $230 a month on top of principal, interest, taxes, and insurance.
Here's the catch that trips people up. On conventional loans, PMI drops off automatically once you hit about 20% equity. FHA doesn't work that way anymore. On most FHA loans today, if you put down less than 10%, that monthly insurance stays for the entire life of the loan. The only way off it is to refinance into a conventional loan once you've built enough equity. That's not a reason to avoid FHA — it's a reason to go in with a plan. For a lot of my buyers the move is: use FHA to get in now, build equity, and refinance to conventional in a couple of years to shed the insurance. Those percentages shift over time, so verify the current numbers, but the shape holds.
FHA vs. conventional: which one's actually cheaper?
The knee-jerk answer is 'FHA, because the down payment's lower,' and that's often wrong. Conventional loans let you put as little as 3% down, and if your credit is decent — mid-700s and up — conventional PMI can actually cost less than FHA's insurance and, crucially, it falls off at 20% equity instead of hanging around forever. So a strong-credit buyer is frequently better off conventional even at a low down payment.
Where FHA wins is when your credit is thinner or your debt-to-income is stretched. Conventional pricing punishes a lower score hard — the rate and the PMI both climb as your score drops. FHA is more forgiving there, so below roughly a 680 score FHA often comes out cheaper on the monthly payment even with its insurance. The honest answer is: it depends on your exact score, your down payment, and the rate environment that week. I run both side by side for every buyer who's on the fence — same house, same down payment, FHA versus conventional, so you're looking at real monthly numbers instead of a rule of thumb.
- Strong credit (roughly 700+): conventional at 3–5% down is usually cheaper, and PMI drops off at 20% equity.
- Thinner credit or high DTI: FHA is more forgiving and often the lower monthly payment.
- FHA insurance can stay for the life of the loan; conventional PMI cancels — factor that into the long game.
- The only way to know is to price both on your actual numbers, not a general rule.
Where FHA loans get tricky in Sonoma County
The program's a workhorse, but it has edges worth knowing before you write an offer. The big one is the appraisal. FHA appraisers check condition, not just value — peeling paint on an older home, a bad roof, exposed wiring, a broken water heater, safety issues around the property. On the wine-country housing stock out here, plenty of it decades old, that matters. A true fixer can stall an FHA loan until repairs are made, which is a problem if the seller won't do them before closing.
The second edge is the offer itself. In a competitive situation, some listing agents see 'FHA' and get nervous about the appraisal and the timeline, and they'll steer their seller toward a conventional or cash offer. That's not fair to FHA buyers, but it's real. The fix is a lender who packages your offer to look as strong as it is — solid pre-approval, a realistic timeline, and an agent who knows how to answer the FHA objection head-on. Done right, an FHA offer competes just fine. I've closed plenty of them against conventional buyers by making sure the file gave nobody a reason to worry.
- Budget for FHA's property-condition standard on older Sonoma County homes.
- A true fixer may not pass an FHA appraisal without repairs first.
- Come in with a strong, fully documented pre-approval so listing agents take the offer seriously.
- Have a lender who can answer the 'it's FHA' objection instead of losing the house to it.
