Buying a home from a family member: gift of equity and the non-arm’s-length file
Buying your parents’ house at a friendly price looks like the simplest transaction in real estate and underwrites like one of the most scrutinized. The price is not the product of a market, so the lender stops trusting the contract and starts trusting the appraisal — and a set of rules that exist only for sales between people who know each other.
What “non-arm’s-length” means in the file
An arm’s-length sale is one between strangers, each acting in their own interest. When the buyer and seller are related — parents and children, siblings, grandparents, in some programs a fiancé or domestic partner — or otherwise connected (employer and employee, a builder selling to its own staff, a tenant buying from a landlord), the transaction is flagged as non-arm’s-length or as an identity-of-interest sale. Nothing about the flag is disqualifying. It changes three things: the appraiser is told about the relationship and works without the usual assumption that price equals value, the underwriter looks harder at where every dollar came from, and some programs cap how much can be financed.
Gift of equity: the down payment nobody has to wire
When a relative sells below market value, the difference between the appraised value and the contract price can be treated as a gift of equity and credited as the buyer’s down payment. No money moves; equity the seller already owned is transferred at closing. Conventional financing allows the entire down payment on a one-unit principal residence to come from an acceptable donor, and a gift of equity is one of the accepted forms.
| Line | Amount | Where it shows up |
|---|---|---|
| Appraised value | $400,000 | Appraisal report — the number the lender lends against |
| Contract price paid to the relative | $340,000 | Purchase agreement |
| Gift of equity | $60,000 | Gift letter, then a credit on the Closing Disclosure |
| Loan amount at 85% of the lower of price or value | $289,000 | Note |
| Cash the buyer actually brings | Closing costs only | Bank statements sourcing the funds |
Two mechanics decide whether that table survives underwriting. First, conventional loan-to-value is computed on the lower of the sale price or the appraised value, so the discount does not automatically become spendable equity — it becomes a smaller loan. Second, the gift has to be documented the way a cash gift is: a signed letter naming the donor, the relationship, the amount, and stating that no repayment is expected, plus the credit shown on the settlement statement. Our guide to gift funds for a down payment covers the letter and the sourcing rules that apply to both forms.
The LTV caps that only exist here
- FHA. Identity-of-interest sales are generally limited to 85% LTV, with exceptions listed in HUD Handbook 4000.1 — among them a buyer who has been a tenant in the property for at least six months before the contract, and certain purchases of a family member’s principal residence. Ask the lender in writing which exception it is applying before you sign anything; the answer changes the down payment by tens of thousands of dollars. The rest of the program is covered in our guide to FHA loan requirements.
- Conventional. Non-arm’s-length purchases of a principal residence are eligible on standard terms; lender overlays are common on second homes and investment property, and a few lenders decline family sales of non-owner-occupied property outright.
- Appraisal waivers. A gift of equity generally makes the file ineligible for value acceptance — you will get a full appraisal, which is the point. See appraisal waivers for the eligibility list.
Taxes: two separate questions
The seller’s side and the buyer’s side are taxed independently, and a friendly price complicates both.
- Gift tax reporting. As of 2026 the annual exclusion is $19,000 per donor per recipient ($38,000 from a married couple electing to split gifts), against a lifetime exemption in the millions. A $60,000 gift of equity from two parents to a married child can often be spread across four donor-recipient pairs; anything above the exclusion means a Form 709 is filed, not that tax is owed. This is a filing question for a tax professional, not a mortgage question.
- The seller’s gain. Selling below market does not create a deductible loss, and the seller still computes gain on the price actually received. A seller who has owned and lived in the home may be able to exclude a large part of that gain; a seller who moved out years ago may not.
- The buyer’s basis. Buying at a discount means a lower cost basis, which can mean a larger taxable gain on a future sale. The savings today are partly borrowed from tomorrow.
What actually goes wrong
The failures in family sales are rarely about the rate.
- Nobody ordered a title search. A parent’s home can carry a forgotten second mortgage, a judgment lien, a Medicaid estate recovery claim, or an unreleased satisfaction from a loan paid off in 1998. Order the commitment the week the contract is signed — our guide to title insurance explains what the exceptions page is telling you.
- The seller’s mortgage was never paid off. A relative cannot simply hand over the deed and keep making payments. The existing note almost certainly contains a due-on-sale clause, and the informal version of this arrangement leaves the buyer with no title protection and the seller with the debt.
- The price was set to avoid a debt. Pricing a house below value to keep it away from a creditor, or to strip equity before a bankruptcy, can be unwound as a fraudulent transfer. That is a question for a lawyer before, not after.
- The relationship was not disclosed. Concealing it from the lender is misrepresentation on a federally related transaction. Disclose it; it is routine.
- No one closed properly. Family or not, the deed has to be drafted, signed, notarized and recorded, and transfer taxes assessed — many states exempt transfers between close relatives, and many do not. Our page on Pennsylvania mortgage laws shows the kind of state-level lines that decide it.

Frequently asked questions
Can a gift of equity cover the whole down payment?
On a conventional one-unit principal residence, the entire down payment may come from an acceptable donor, and a gift of equity qualifies. Closing costs and any required reserves can often be covered as well, though reserve rules are stricter than down payment rules. On FHA, a family gift may fund 100% of the minimum required investment, but an identity-of-interest sale may still be capped at 85% LTV unless an exception applies.
Does the house have to be appraised if we already agreed on a price?
Yes, in practice. The lender lends against value, not against a family agreement, and a gift of equity is defined by the gap between the two — which cannot be measured without an appraisal. Expect the appraiser to be told about the relationship, and expect no appraisal waiver.
What if the appraisal comes in below the family price?
Then the loan is sized on the appraised value and the gift of equity shrinks or disappears. The usual fixes are the same as in any purchase: renegotiate the price down to value, bring the difference in cash, or challenge the report with better comparable sales. Our guide to the appraisal gap walks the options.
Is a gift of equity taxable income to me?
A gift is not income to the person receiving it. The reporting obligation, if any, sits with the donor and is a filing rather than a tax bill for most families. Confirm the specifics with a tax professional, because the seller’s capital gain and your future basis are affected as well.
