The home, and whether you will live in it
FHA's 203(k) is for a home you will live in, from one to four units, and it can also renovate the inside of an eligible condominium unit; FHA does not insure one on an investment property, except for HUD-approved nonprofits and government agencies. Fannie Mae's HomeStyle Renovation and Freddie Mac's CHOICERenovation can also finance a second home or an investment property with one unit, within each program's rules, and a condominium or planned development unit when the association's rules allow the work. On a HomeStyle loan, work on a condominium stays inside the unit. Each starts from a home that exists: neither conventional program pays to demolish a house and build a new one, and FHA's Standard 203(k) can rebuild only on the foundation that is there.
Your income and credit
The lender documents and verifies your income, assets and credit, and the credit rules are FHA's, Fannie Mae's or Freddie Mac's own. Expect to provide records such as pay stubs, tax returns and bank statements. On a CHOICERenovation loan, if you will rent somewhere else while the work is done, Freddie Mac's rules can require that rent to be counted with your other debts.
The contractor, the plans and the budget
The lender reviews the job as well as you, before closing. You choose the contractor, licensed where the law requires it, and on a HomeStyle loan the lender may not choose one for you or steer you to one; the lender checks the contractor's credentials and a signed contract that sets out the work, the price and the schedule. A Standard 203(k) adds an FHA-approved 203(k) Consultant, chosen by the lender, who inspects the home and writes up each item of work and its cost; that inspection is not a home inspection, and the consultant's agreement with you has to say so. A Limited 203(k) needs no consultant but takes only minor, nonstructural work, under a cost cap FHA sets. Bring real bids, not an estimate from a calculator.
The value with the work finished
The appraiser values the home as it will be once the work is done, working from the plans, the bids or the consultant's write-up, and that value is one of the limits on the loan. If it comes in lower than the plan assumed, the loan can be smaller than the job needs, and if the plans change during the work, the appraiser may have to value the home again. HomeStyle and CHOICERenovation also cap the cost of the work as a share of the value, and the Limited 203(k) has a cost cap of its own, so set the budget against those limits before you commit to a contractor.
Where a renovation loan is not the answer
A job small enough to pay for from savings may not need a loan at all, a new house on a lot is a construction loan, and a property bought to renovate and resell is what a fix-and-flip loan is for. On a home you own, a renovation loan replaces your first mortgage if you have one, and so does a cash-out refinance: either way, the new loan's rate and terms apply to the whole mortgage balance, not only to the new money. If you have a first mortgage you want to keep, a home equity line of credit (HELOC) leaves it in place, at the cost of a second payment and a rate that can change. Our refinance page sets out what a cash-out refinance does to your balance and your payment, and a second unit on your lot starts on our ADU page.
