Using a HELOC for a renovation

Renovations are paid in stages, and a HELOC is built for that. You draw for the deposit, the rough-in and the finish, and pay interest only on what's out.

Why it fits renovation

• Draw when invoices are due. No interest on money still waiting for the cabinets to arrive.
• Room for surprises. Size the line 10%–20% above the bid. Unused room costs nothing on most lines.
• Possible tax deduction. HELOC interest can be deductible when the money buys, builds or substantially improves the home securing it. Keep contracts, permits and receipts, and confirm with your tax preparer.
• Keeps your first mortgage. No need to refinance a low rate to pay for a kitchen.

Common projects

Questions to ask the lender

1. What's the margin over prime, and is there a rate floor?
2. Is there a minimum draw, an annual fee, or an early-closure fee?
3. Can I lock part of the balance at a fixed rate once the project is done?
4. Is the value based on today's home or the finished one? Most HELOCs use today's value.

HELOC vs. other ways to pay

Contractor financing is quick but often carries promotional rates that jump after 12–24 months. Renovation mortgages such as Fannie Mae HomeStyle or FHA 203(k) can lend against the after-repair value, but they replace your first mortgage and take longer. A personal loan works for projects under about $20,000. For most remodels on a home with a low first-mortgage rate, a HELOC is the default to beat. Check your line with the borrowing calculator.

Sizing the line for a project

Start from the contractor's bid, then add room for the things bids leave out:

• Contingency: 10%–20%. Older homes hide surprises behind walls: knob-and-tube wiring, rot, undersized beams. Kitchens and bathrooms run over most often.
• Permits and design: architect or designer fees, engineering, plan check and permit fees can add 5%–15% on larger jobs.
• Living costs during the work: takeout while the kitchen is gutted, a short-term rental if you have to move out.
• Finishes you'll choose later: appliances, lighting and window coverings often end up above the allowance in the bid.

A $90,000 bid often becomes a $105,000–$115,000 project. It's better to open a line with room and not use it than to come back for a second loan halfway through.

How draws line up with the work

Most contractors bill against milestones: a deposit (often capped by state law; California, for example, limits home improvement deposits to $1,000 or 10% of the contract, whichever is less), then payments at demolition, rough-in, drywall and completion. With a HELOC, you draw each payment when it's due and pay interest only on what you've drawn. Keep a simple ledger of each draw against the invoice; it helps at tax time if you deduct the interest.

Protecting yourself while paying a contractor

• Check the contractor's license and complaint history with your state licensing board before signing.
• Never pay far ahead of the work. Match each payment to work you can see.
• Get lien releases from the contractor and major suppliers as you pay. In many states, an unpaid supplier can put a lien on your home even if you paid the contractor.
• Keep the final payment until the punch list is done and the permit is signed off.

Will a home renovation pay for itself at resale?

Usually not dollar for dollar. Industry cost-versus-value surveys consistently show most remodels recover well under their cost at resale; smaller, practical projects (a garage door, siding, a minor kitchen refresh) recover more than large luxury ones. Renovate because you'll use and enjoy the space, and treat any added value as a bonus. Projects that fix a real problem (a failing roof, a leaking window) protect value that would otherwise be lost.

Deducting the interest

HELOC interest can be deductible when the money is used to buy, build or substantially improve the home that secures the line, and you itemize. Repairs and maintenance don't count on their own, but repairs done as part of a larger improvement project can. Total mortgage debt limits apply. Keep invoices and your draw ledger together. The rules in detail.

More questions

Can I get a HELOC if the house needs major work right now?

Often yes, if it's safe and livable. Lenders may not lend against a home with a missing roof, no working kitchen or a serious structural problem. For a home that needs a lot before it's livable, look at a renovation loan.

Can I do the renovation work myself with a HELOC?

Yes. The lender doesn't control how you spend the line. Keep receipts for materials if you plan to deduct the interest, and pull permits where they're required; unpermitted work can cause problems when you sell.

What if my renovation costs less than my HELOC limit?

You pay interest only on what you draw, so unused HELOC room costs nothing on most lines. Leave the rest of the line open, or ask the lender to lower the limit.
