When you buy or sell real property to a family member, the IRS requires that the transaction be documented at arm's-length fair market value, regardless of the actual purchase price. A parent selling to a child, a sibling buying from another sibling, or any family property transaction requires professional appraisal documentation to satisfy lenders, the IRS, and avoid gift tax complications. Family transactions that are underpriced or overpriced without proper appraisal support can trigger IRS audits and unexpected tax liability.
The IRS treats family transactions differently from arm's-length sales. If a parent sells a $400,000 home to their adult child for $250,000 as a "gift" or "discount," the IRS may view the difference as a taxable gift requiring gift tax returns and potentially consuming gift tax exemptions. An appraisal that establishes fair market value allows the transaction to be documented properly and protects both buyer and seller from IRS scrutiny. Lenders financing family transactions also require appraisals to document that the purchase price is reasonable and that there is adequate collateral for the loan.
An arm's-length fair market value appraisal analyzes comparable sales and market conditions as if the transaction were between unrelated parties. This appraisal becomes the documentation that proves the transaction price is defensible and compliant with IRS regulations. Whether you're buying from parents, selling to a sibling, or transferring property within the family, the appraisal establishes that no gift or tax evasion was intended—just normal market-rate real estate activity.
If the transaction involves financing from a bank or mortgage company, the lender will require an appraisal regardless of family relationship. Additionally, if the purchase price differs from fair market value, you'll want appraisal documentation in your records to support your IRS reporting if the return is ever audited. I prepare family transaction appraisals specifically designed to meet lender requirements and withstand IRS examination.
Federal gift tax law allows you to give up to a certain amount annually without filing a gift tax return (the 2026 annual exclusion is $18,000 per person). If a family property transaction involves a below-market price that exceeds this threshold, you may need to file Form 709 (Gift Tax Return). An appraisal establishes the actual gift amount for tax reporting purposes and ensures you're in compliance with IRS rules.
Family property transactions can create tension around pricing and fairness. An objective, professional appraisal removes emotion from the transaction and gives both parties confidence that the price is fair and market-based. The appraisal protects both buyer and seller and provides documentation for your records that will satisfy any future IRS inquiry.
Family transaction appraisals start at $299 for standard residential properties. I recommend ordering the appraisal early in the transaction process so both parties can plan with confidence.
