Lending family money for a house: gift, loan, or family mortgage?

For parents, grandparents, and relatives helping someone buy a home. Last reviewed October 2, 2026.

The short answer: if you don’t need the money back, gift it. If you do, skip the informal IOU and set up a recorded family mortgage: a written note at or above the IRS minimum rate, secured by a mortgage or deed of trust recorded with the county, with payments tracked and a matching interest statement for both of you each year. It protects the lender, lets the borrower deduct the interest, and keeps the rest of the family in the loop.

Why the informal IOU causes the most trouble

The handshake loan is the most common choice and the one that most often goes wrong. Without a recorded lien, the lender has no claim on the house if it’s sold, refinanced, or caught up in a divorce or a creditor’s claim. Without a written schedule, nobody agrees on what’s been paid. Without the right rate, the IRS can treat part of the arrangement as income to the lender and a gift to the borrower. And because the loan isn’t secured, the borrower can’t deduct the interest.

Seven steps to a family mortgage done right

  1. Agree on the terms in writing: the amount, the term, the payment, what happens if a payment is late, and what happens if the home is sold.
  2. Set the rate at or above the IRS AFR for the loan’s term, in the month the loan is made. See this month’s AFR rates.
  3. Sign a promissory note. A real estate attorney in the property’s state should prepare it.
  4. Secure it with a mortgage or deed of trust, and record it with the county. Recording is what protects the lender and makes the interest deductible.
  5. Set up the payment schedule and method. Automatic bank transfers create a clean record.
  6. Keep a shared ledger that both of you can see, updated whenever a payment is made, missed, or doubled up.
  7. Exchange matching year-end interest statements so the borrower’s deduction and the lender’s income agree. See who sends the 1098.

Two cautions before you lend

  • If a bank mortgage is involved too, tell the bank. Most lenders count a family loan as debt when they qualify the borrower. Signing a gift letter for money that is really a loan can be mortgage fraud.
  • Selling your own property on terms is regulated differently. If you’re the seller carrying the note, rather than lending cash, federal and state rules may limit how many seller-financed sales you can do and what you must disclose. Talk to a real estate attorney in the property’s state.

Common questions

What is the best way to lend money to family for a house?

If you expect to be repaid, a recorded family mortgage is usually the cleanest option: a promissory note at or above the IRS AFR, secured by a recorded mortgage or deed of trust, with payments tracked and matching year-end interest statements. It protects the lender and lets the borrower deduct the interest.

Should I just gift the money instead?

If you don’t need it back, a gift is simpler. In 2026 you can give $19,000 per recipient without filing a gift tax return, and larger gifts usually just use part of your lifetime exemption. A gift can’t be “called” later, though, and it doesn’t create a deduction for the recipient.

Can a family loan be used for a down payment with a bank mortgage?

Sometimes, but you must disclose it. Most lenders count a family loan as debt in qualifying. Describing a loan as a gift on a gift letter when it’s really a loan can be mortgage fraud.

How much does it cost to set up a family mortgage?

Costs range from close to nothing for a do-it-yourself note to a few thousand dollars with a full-service company. Most families need an attorney to prepare and record the note and mortgage, plus a way to track payments and produce year-end statements.
