The short version
A renovation loan rolls the purchase price and the cost of repairs into a single mortgage, and it qualifies you against the home's value after the work is finished — not what the tired, dated house appraises for today. That's the whole trick. You're borrowing against the finished product, so you can buy a place that a normal loan would reject and turn it into the house you actually wanted, without a second loan or a pile of cash for the remodel.
The two workhorses are the FHA 203(k) and the conventional versions — Fannie Mae's HomeStyle and Freddie Mac's CHOICERenovation. They all do roughly the same thing with different rules on down payment, credit, and how much red tape comes with the work. Out here, where a big share of the listings are older homes that scared off the last three buyers, this is one of the more useful loans I write and one of the most underused. It's also one of the easiest to mess up if you go in without a plan. Here's how it actually works.
What is a renovation loan, exactly?
On a normal purchase, the lender appraises the home as it sits and lends against that number. If the kitchen is from 1978 and the roof is shot, that's the value you're stuck with — and good luck getting a conventional loan to close on a house with a failed roof anyway. A renovation loan flips the order. You get bids for the work up front, the appraiser assigns an 'after-repair value' based on the finished scope, and the lender funds the purchase plus a construction budget against that higher number.
The repair money doesn't land in your checking account. It goes into an escrow account and gets released to your contractor in stages — draws — as the work passes inspection. So the seller gets paid at closing like any sale, and the renovation funds sit in reserve and pay out as the project moves. You make one monthly payment on the whole thing. When it's done, you've got an updated house and a single mortgage, instead of a fixer plus a HELOC plus a credit card you swore you wouldn't touch.
FHA 203(k) or conventional renovation — which one?
The FHA 203(k) is the more forgiving of the two on credit and down payment — 3.5% down and it tolerates lower scores, which makes it the go-to for first-time buyers and anyone whose credit isn't pristine. It comes in two flavors. The Limited 203(k) is for cosmetic-to-moderate work with a repair cap (the limit was raised recently — verify the current figure for your file), and it skips a lot of the paperwork. The Standard 203(k) handles bigger, structural projects, has no repair cap under the FHA loan limit, and requires a HUD consultant to oversee the scope and the draws. The catch with any FHA loan is mortgage insurance, which sticks around for the life of the loan on most 203(k)s.
The conventional route — HomeStyle and CHOICERenovation — usually wants a stronger credit profile but rewards you for it. Down payments can start around 5% (sometimes 3% for eligible first-time buyers), the private mortgage insurance drops off once you hit 20% equity instead of hanging on forever, and the programs allow work FHA won't touch, including certain luxury items and, on the conventional side, financing renovations on a second home or investment property. My rule of thumb: if your credit and down payment are solid, run the conventional numbers first, because losing the permanent mortgage insurance is real money over time. If you're tight on either, the 203(k) is what gets you in the door.
- FHA 203(k): 3.5% down, flexible credit, but mortgage insurance typically stays for the life of the loan.
- Limited 203(k) — lighter work, a repair cap, less paperwork; Standard 203(k) — big/structural work, HUD consultant required.
- Conventional (HomeStyle / CHOICERenovation): stronger credit, as little as 5% down, PMI drops at 20% equity.
- Conventional can finance second homes and investment properties; FHA is owner-occupant only.
- Down payment percentages and caps are approximate — verify the current numbers for your scenario.
What kind of work can I actually finance?
More than people assume. Kitchens and baths, roofs, windows, HVAC, electrical and plumbing, flooring, a new foundation, additions, dialing in a permitted ADU, accessibility upgrades, even landscaping and a pool on the conventional programs. If it's attached to the house and adds value, it's usually in bounds. Structural work, mold and pest repairs, bringing an old system up to code — all fair game, and often the whole reason the house was cheap.
What you can't do is bankroll your lifestyle with it. The money has to go into the property, on the scope the appraiser valued, done by a licensed contractor with a real bid. You can't pad the budget to cover your moving costs or pocket the difference. And there's a timeline — the work has to start and finish inside a set window (commonly around six months, program depending), so this isn't the loan for a someday-maybe remodel. It's for a house with a defined project you're ready to run.
- Eligible: kitchens, baths, roofing, windows, HVAC, electrical, plumbing, foundation, additions, code upgrades, ADUs.
- Conventional programs also allow pools, landscaping, and some luxury finishes FHA won't cover.
- Work must be done by a licensed contractor against a documented bid — no DIY sweat equity on most programs.
- There's a hard start-and-finish window, so it's for a defined project, not an open-ended wish list.
How is the process different from a normal mortgage?
It's a mortgage with a construction project bolted on, so there are extra moving parts and you should plan for a longer timeline — figure several weeks past a standard purchase, sometimes more on a Standard 203(k). The big difference is the contractor. Before we can close, you need a licensed, insured contractor with a detailed written bid tied to the scope the appraiser used. A vague 'about forty grand for the kitchen' won't fly. The lender is underwriting the contractor and the plan almost as hard as it's underwriting you.
Once you close, the repair funds sit in escrow and release in draws as the contractor completes phases and inspections sign off. The budget also carries a contingency reserve — usually in the 10% to 15% range — because old houses hide surprises, and you want cushion built in before you open the walls. If you don't spend it, on most programs it either goes toward principal or comes back to you. The paperwork is heavier than a plain purchase, no way around it. That's exactly why doing it with someone who's closed these before matters more here than on a vanilla loan.
Where do these loans go sideways in Sonoma County?
The contractor is where most deals live or die. Good contractors out here are booked, and a lot of them don't want to deal with the draw schedule and inspections a renovation loan requires — they'd rather take a cash remodel. So you have to find one who'll work within the program and put a real bid on paper, on your closing timeline, not theirs. Start that search the day you go under contract, not after. I've seen more of these stall over a contractor who ghosted than over anything on the lending side.
The other Sonoma County wrinkles: permits and older systems. A lot of our housing stock is genuinely old, and once you open it up you find knob-and-tube wiring, a foundation that needs bracing, or work a prior owner did without a permit that now has to be corrected and re-permitted through the county or city. Build that reality into the scope and the contingency instead of hoping. And a note on fire rebuilds and homes in high fire-risk zones — the renovation math still works, but insurability drives everything out here, so get a real insurance quote on the specific address early, because a house you can't insure is a house you can't close on regardless of how good the remodel budget looks.
- Line up a licensed contractor willing to work the draw schedule the moment you're under contract — this is the #1 stall point.
- Older homes surface hidden issues: dated wiring, foundation work, unpermitted prior work that must be corrected.
- Budget the contingency reserve honestly — old houses always find a way to spend it.
- Confirm insurability on the specific address early; fire-zone insurance can make or break the deal.
Is a renovation loan right for me?
It's a strong fit if you've found a house in the right location that's priced low because it needs work, you don't have a spare pile of cash for the remodel, and you're willing to run a real project with a real contractor for a few months. It's also a smart play in a market like ours where move-in-ready homes get bid up — the fixer everyone else scrolled past often carries less competition and more room to build equity as you improve it. Buy at the dated price, finance the upgrades, own a house worth more than you're into it for.
It's the wrong tool if you want to close fast, can't commit to a defined scope, or you're really hoping to do the work yourself over a couple of years. If that's you, buying move-in-ready or using a straight purchase and improving over time is cleaner. The way to know is to run your specific numbers — the house, the scope, the after-repair value, and which program leaves you in the best spot. That's a twenty-minute conversation, and it'll tell you fast whether this is your move. Bring me a listing you're eyeing and a rough idea of the work, and I'll tell you if it pencils.
