A renovation loan for an older home lets you borrow for the purchase (or a refinance) and the planned work in one mortgage, instead of buying first and hunting for repair money later. For a mid-century modern house that needs a roof, new glass or a heating update, that structure can decide whether a project happens at all.
This guide walks through the main programs: FHA's 203(k), Fannie Mae's HomeStyle Renovation and Freddie Mac's CHOICERenovation, plus the home equity options open to current owners. It covers the rules that shape a mid-century project, including what counts as structural, how long the work can take and how money is released, and ends with questions to ask a lender. Program rules change, so treat this as a starting point and confirm details with a licensed mortgage professional.
Why mid-century houses and renovation loans go together
Palo Alto's Eichler design guidelines list the concerns owners raise about these homes: flat roofs prone to leaks, foundations without crawl spaces, single-pane glass, a lack of insulation, inefficient radiant heat, nonstandard siding and carports instead of garages. Several of those items can show up on the same inspection report, and tackling them one at a time can mean several rounds of work.
A renovation mortgage is built for that situation. Fannie Mae describes its HomeStyle Renovation loan as one that lets a borrower purchase a property or refinance an existing loan and include funds in the loan amount for renovation costs. The limits are tied to the home's "as completed" appraised value, meaning its value after the planned work, not only its value today.
Condition matters for ordinary financing too. Fannie Mae's Selling Guide rates condition from C1 to C6. A home rated C6, which has substantial damage, isn't eligible as is: it must be repaired to at least C5, and the appraisal is made subject to completion of those repairs. A renovation loan is one way to fund that work as part of the purchase. (New appraisals submitted on or after November 2, 2026 use a redesigned appraisal dataset with its own Fannie Mae policy supplement; Freddie Mac says the rating scale is unchanged but the definitions were rewritten, so ask your lender whether anything differs for your loan.)
FHA 203(k): Standard and Limited
HUD's Section 203(k) program comes in two versions:
Standard 203(k) is for major rehabilitation and repair, including major renovations and structural additions. The rehabilitation cost must be at least $5,000, and the total value of the property must fall within the FHA mortgage limit for the area. The lender selects a HUD-approved 203(k) consultant from HUD's roster for the project.
Limited 203(k) is for minor remodeling and non-structural repairs or improvements, including preparing a home for sale. Borrowers can finance up to $75,000 into the mortgage, and a consultant is optional.
HUD raised the Limited 203(k) cap from $35,000 to $75,000 in 2024 and said the limit will be reviewed annually; as of November 2026, HUD's program page still lists $75,000, but confirm the current figure with your lender. The same update set the rehabilitation period at 12 months for the Standard version and 9 months for the Limited version, extended the time a Limited borrower may be unable to occupy the home during work from 15 to 30 days, and allowed consultant fees to be financed on Limited loans. HUD's 203(k) program page has the current rules.
For a post-and-beam house, the structural line is the one to watch. Adding a room or reworking beams is a different kind of project than repainting or replacing fixtures. Before you finalize bids, ask the lender how it would classify each item on your scope, since that decides which version fits.
Fannie Mae HomeStyle and Freddie Mac CHOICERenovation
Fannie Mae's HomeStyle Renovation mortgage has its own rules, published in its Selling Guide:
Property types: a one- to four-unit principal residence, a one-unit second home, a one-unit investment property, a manufactured home, or a unit in an eligible PUD, condo or co-op project.
Renovation budget: for a purchase, renovation costs can't exceed 75% of the lesser of the purchase price plus renovation costs, or the "as completed" appraised value. For a refinance, the cap is 75% of the "as completed" value. Manufactured homes have a lower cap of 50%.
Type of work: there are no required improvements or restrictions on the types of renovations, but improvements should be permanently affixed to the property, with exceptions for certain appliances in kitchen and utility room remodels. Complete tear-down and reconstruction isn't allowed.
Do-it-yourself work: it may not represent more than 10% of the "as completed" value.
Timing: work must be completed no later than 15 months from the date the loan closes. Fannie Mae may allow a limited extension, not to exceed 18 months from closing.
How money moves: renovation funds go into an escrow account. The lender may fund up to 50% of planned costs at closing as an initial draw, then releases funds only as work is completed, after periodic inspections, by a check issued jointly to the borrower and contractor or by a wire to the contractor with the borrower's written consent.
Contingency and overruns: a contingency reserve isn't required for a one-unit property, though the lender may set one up; for two to four units it's 10% of renovation costs, and the lender may raise it to 15%. If costs rise, the lender may not increase the loan amount to cover them.
Freddie Mac's CHOICERenovation mortgage works on a similar idea: the borrower uses the loan proceeds to pay for the renovations. Freddie Mac lists one- to four-unit primary residences, one-unit second homes, one-unit investment properties, condo, PUD and co-op units, and manufactured homes as eligible. Lenders may add their own requirements on top of either program, so compare offers side by side.
Options if you already own the house
Owners who plan to stay put have other choices besides a renovation refinance. The Consumer Financial Protection Bureau explains the difference between the two common home equity products:
Home equity loan: a specific amount of money borrowed against the equity in your home, received in a single payment, with a fixed or adjustable rate.
Home equity line of credit (HELOC): a line of credit, like a credit card, borrowed against your home's equity. You can draw funds several times up to a maximum, and HELOCs usually carry adjustable rates.
If you already have a mortgage, the CFPB notes that either one is a second mortgage you pay in addition to your first. Its comparison page is a useful plain-language read before you talk to a lender. A HomeStyle refinance, by contrast, sizes the renovation budget against the home's "as completed" value.
Planning a mid-century project around the loan
Renovation financing rewards preparation. These steps keep the loan and the house working together:
Write the scope before the offer. Get an inspection, then a prioritized list: envelope and systems first (roof, glazing, heat, electrical), finishes second.
Design for the house you're buying. Clerestories, glass walls and exposed beams define these homes, so a remodel should work with them. Our mid-century modern design services and design guidelines page help keep a remodel in character.
Plan for permits and code items. In California, when a permit applicant alters or improves a single-family home built on or before January 1, 1994, noncompliant plumbing fixtures must be replaced with water-conserving ones before the city gives final permit approval. Ask your contractor to include that in the bid, and check with the city's building department on how it applies.
Build the schedule around the program clock: 12 or 9 months for the two 203(k) versions, 15 months for HomeStyle.
Keep cash in reserve. Because a HomeStyle lender can't raise the loan amount when costs rise, plan for surprises such as hidden decay under a flat roof.
Decide what to keep. Our Eichler renovation guide covers which original features are worth restoring and which updates tend to be reversible.
Questions to ask a lender
Which renovation programs do you offer, and which would you suggest for this scope?
How will you classify each item on my list as structural or non-structural?
How do you order the "as completed" appraisal, and what do you need from my contractor?
What is your draw schedule, and who inspects before each release?
What contingency reserve will you require, and what happens to unused funds?
What requirements do you add beyond the program rules?
For a buyer's checklist that pairs with these questions, see our buyer resources.
Frequently asked questions
What is the difference between the Standard and Limited 203(k)?
The Standard 203(k) covers major rehabilitation, including structural additions, has a minimum rehabilitation cost of $5,000 and requires a HUD-approved consultant chosen by the lender. The Limited 203(k) covers minor, non-structural work, lets borrowers finance up to $75,000 into the mortgage, and makes the consultant optional.
How long do I have to finish the work?
Under HUD's 2024 update, the rehabilitation period is 12 months for the Standard 203(k) and 9 months for the Limited version. Fannie Mae's HomeStyle requires completion no later than 15 months after closing, with a possible limited extension to 18 months.
Can I do some of the renovation myself?
Rules differ by program. Fannie Mae's HomeStyle allows do-it-yourself work up to 10% of the home's "as completed" value. Ask your lender about its own rules before you plan on sweat equity.
Can a renovation loan fund work on a home with substantial damage?
Often that's the point of one. Fannie Mae requires a home rated C6 to be repaired to at least C5, with the appraisal made subject to completion of repairs, and a renovation mortgage can include those costs in the loan amount. Your lender decides what's eligible for a specific house.
