A Bargain With Strings
Your parents want to sell you their house for substantially less than what it's worth. That sounds like an extraordinary opportunity, but the discount can have tax, mortgage, Medicaid, and inheritance consequences. Before signing anything, you need to understand that the IRS may treat part of this "sale" as a gift.
Start With Market Value
First, establish what the house is actually worth. For federal gift-tax purposes, fair market value generally means the price willing, informed parties would agree upon without either being compelled to act. An independent appraisal can provide crucial documentation if the IRS later questions the transaction.
The Discount May Be Gifted
Suppose the house is worth $500,000 and your parents sell it to you for $300,000. The $200,000 difference can generally constitute a gift for federal gift-tax purposes. Calling the transaction a "sale" does not necessarily prevent the bargain element from being treated as a transfer of value.
You Usually Owe Nothing
Receiving a large gift generally doesn't mean you immediately owe federal gift tax. Gift-tax reporting and any gift-tax liability ordinarily fall on the donor, meaning your parents. More importantly, filing a gift-tax return doesn't necessarily mean your parents will actually have tax to pay.
Annual Exclusions Are Smaller
For 2026, the federal annual gift-tax exclusion is $19,000 per recipient from each donor. Thus, two parents can potentially provide $38,000 of qualifying present-interest gifts to one child using their individual exclusions. A substantial discount on a house can easily exceed those amounts.
Then Comes Lifetime Exclusion
Amounts above the annual exclusion can generally reduce the donor's available lifetime gift and estate tax exclusion instead of producing immediate tax. For 2026, the federal basic exclusion amount is $15 million per individual, meaning many families will face reporting requirements without ultimately owing federal gift tax.
Form 709 May Apply
If your parents make a reportable gift through the transaction, one or both may need to file IRS Form 709. The IRS instructions specifically request supporting information for certain gifts, including appraisals, transfer documents, and documentation concerning partially gifted assets, making good records especially important with real estate.
Your Basis Gets Complicated
The bigger surprise may come years later. Your tax basis is important because it helps determine taxable gain when you eventually sell. Property received partly as a gift can carry basis consequences that are much less favorable than simply assuming your basis equals the home's market value when you acquired it.
Gifts Can Carry Basis
With gifted property, the recipient generally needs to know the donor's adjusted basis, the property's fair market value when transferred, and any gift tax paid. Consequently, your parents' original purchase price, improvements, depreciation, and other basis adjustments can remain important long after the house becomes yours.
Inheritance Works Differently
Had you instead inherited the house after your parents' deaths, federal tax rules would generally establish its basis using fair market value on the date of death, or an alternate valuation date when applicable. That difference can dramatically affect the capital gain generated by a later sale.
Consider A Simple Example
Imagine your parents bought the house decades ago for $100,000 and it is now worth $500,000. Transferring it cheaply during their lifetimes can preserve some of that old basis under gift rules. Inheriting a $500,000 property, by contrast, would generally establish basis around its date-of-death market value.
The Difference Can Matter
If you later sell for $550,000, a basis near $500,000 creates a very different potential gain from one connected to your parents' much lower adjusted basis. Other rules and adjustments can change the calculation, which is why comparing a lifetime transfer with an eventual inheritance is essential.
Home Exclusions Can Help
If the property becomes your principal residence, you might eventually qualify to exclude up to $250,000 of gain, or up to $500,000 on many joint returns. Generally, you must satisfy ownership and residence requirements covering at least two years during the five-year period preceding the sale.
Your Parents Have Taxes
Do not focus solely on your side of the transaction. Your parents must consider their own potential gain from selling the property. If it is their principal residence and they meet the requirements, they too may qualify for the federal home-sale exclusion of up to $250,000 or $500,000.
Financing Needs Attention
If you need a mortgage, tell your lender exactly what is happening. A below-market family sale can involve a "gift of equity," where part of the seller's equity is effectively transferred to you. Fannie Mae permits qualifying gifts of equity for principal-residence and second-home purchase transactions.
Equity Can Fund Closing
Under Fannie Mae rules, an eligible gift of equity can fund some or all of your down payment and closing costs, including prepaid items. It cannot be counted toward financial reserves, however, and the lender must retain documentation including a signed gift letter and settlement statement showing the gift.
Get The Appraisal Anyway
Even when everyone agrees on the family price, an independent appraisal can establish a defensible fair market value. That figure helps quantify the gift, supports tax documentation, and gives lenders information they may need. Without reliable valuation evidence, you could be arguing years later about what the discount originally represented.
Think About Your Siblings
Tax law is only half the problem. If your parents have other children, decide whether the discount is intended as an extra gift to you or an advance against your eventual inheritance. Those are very different family arrangements, and leaving the answer unwritten can invite disputes when their estate is settled.
Put Intent In Writing
Your parents' estate-planning documents should reflect what they actually intend. If a $200,000 equity gift should reduce what you later inherit, their attorney can advise how to coordinate that intention with their will, trust, or other estate plan under applicable state law rather than relying on family memories.
Medicaid Changes Everything
There is another issue families sometimes overlook. Medicaid rules can penalize transfers for less than fair market value when someone later applies for certain long-term care benefits. For applicable long-term services and supports, Medicaid examines transfers made during the five years preceding the application.
Timing Could Become Costly
If your parents are older and could potentially need Medicaid-funded long-term care, a bargain sale deserves specialized elder-law advice before it happens. Selling a valuable house substantially below market can be treated as a less-than-fair-market-value transfer for Medicaid purposes and potentially delay eligibility for covered long-term care.
State Rules Matter Too
Federal taxes are only one layer. State estate or inheritance taxes, property-tax reassessments, transfer taxes, homestead rules, Medicaid administration, and real-estate requirements vary by jurisdiction. Before using federal rules to estimate the overall cost, have someone examine the consequences specifically in the state where the property sits.
Compare Your Alternatives
Ask an estate-planning attorney and tax professional to compare several scenarios: buying now at market value, buying now with a documented gift of equity, receiving a larger lifetime gift, or inheriting the property later. The cheapest purchase price today is not automatically the option producing the lowest lifetime tax cost.

Document Every Number
Keep the appraisal, closing statement, gift letters, Form 709 filings, records of your parents' original basis, receipts for major improvements, and your own subsequent improvement records. Decades from now, those documents may determine your taxable gain, and reconstructing a parent's property records after death can be frustrating or impossible.
Make It A Real Deal
Your parents can absolutely choose to give you a financial advantage, but treat the transaction like the significant asset transfer it is. Establish market value, disclose the gift element, involve your lender, document your parents' estate-planning intentions, and calculate the future basis consequences before deciding how good the "deal" really is.
