Yes, you can legally sell your house to your son for $100, but the transaction carries significant tax obligations, legal requirements, and financial risks that most homeowners do not anticipate. The low sale price does not eliminate your responsibilities — it often creates new ones. Understanding what the IRS, your state, and future buyers will see in this transaction is essential before you sign anything.
Is It Legal to Sell Your House to a Family Member for $100?
Selling your home to a family member for $100 is legal in most jurisdictions. A valid real estate sale requires an offer, acceptance, and consideration — meaning something of value exchanged. One hundred dollars qualifies as legal consideration. The transaction can be recorded, the deed transferred, and title conveyed just as it would be in any standard sale.
However, legality and financial consequence are two separate things. The IRS does not treat a $100 sale between family members as a standard arm’s-length transaction. It treats the difference between the sale price and the home’s fair market value as a gift — and gifts above certain thresholds trigger federal gift tax rules.
What Makes a Below-Market Sale Valid
For the sale to hold up legally, it must follow the same procedural steps as any real estate transaction. A purchase agreement must be signed. A deed — typically a warranty deed or quitclaim deed — must be prepared, signed, notarized, and recorded with your county recorder’s office. Title should be searched to confirm there are no liens or encumbrances that would complicate the transfer. Skipping these steps, even in a family transaction, can create title defects that affect your son’s ability to sell or refinance the property later.
The Role of Fair Market Value in Family Transfers
Fair market value is the price a willing buyer and a willing seller would agree on in an open market. When you sell a home worth $350,000 for $100, the IRS considers the $349,900 difference a taxable gift. This does not mean you automatically owe gift tax — the federal lifetime gift and estate tax exemption is substantial — but it does mean you must file IRS Form 709, the United States Gift Tax Return, for the year the transfer occurs. Failing to file, even when no tax is owed, is a compliance error that can create problems later.
How the transfer is structured legally affects both the deed type chosen and the disclosures required in your state — details that vary significantly depending on where the property is located.
What Are the Tax and Financial Consequences?
The tax consequences of a $100 home sale fall on both sides of the transaction — yours at the time of sale and your son’s when he eventually sells the property.
Gift Tax Rules and the IRS Annual Exclusion
The IRS allows individuals to gift up to $18,000 per recipient per year (as of 2024) without filing a gift tax return. A home worth hundreds of thousands of dollars far exceeds this annual exclusion. The excess counts against your lifetime exemption, which is currently over $13 million per individual. Most homeowners will not owe actual gift tax, but the filing requirement still applies. Your estate planning attorney or CPA should be involved before the transaction closes.
Capital Gains Exposure Your Son Inherits
This is where many families encounter an unexpected problem. When you sell your home at fair market value, your son receives a stepped-up cost basis — meaning his taxable gain is calculated from the current value. In a $100 sale, he inherits your original cost basis instead. If you purchased the home for $80,000 decades ago and it is now worth $350,000, your son’s cost basis remains $80,000. When he sells, he could owe capital gains tax on the full $270,000 appreciation — a liability that a standard inheritance would have largely eliminated.
Capital gains exposure your son inherits through a below-market sale is one of the most misunderstood consequences of family property transfers, and it deserves careful review with a tax professional before the deed is signed.
What Risks Should You Know Before Proceeding?
Beyond taxes, a $100 home sale carries practical risks. If you receive Medicaid benefits or anticipate needing them within five years, transferring your home for below fair market value can trigger a Medicaid look-back penalty that delays your eligibility for long-term care coverage. Creditors can also challenge below-market transfers as fraudulent conveyances if you have outstanding debts at the time of the sale. Your son’s mortgage lender, if he ever refinances, will also scrutinize the acquisition price and may require a full appraisal to establish current value. None of these risks make the transaction impossible — but each one requires advance planning to manage correctly.
Conclusion
Selling your house to your son for $100 is legally possible, but it is rarely as simple as it appears. Gift tax filing requirements, carryover cost basis, Medicaid look-back rules, and title integrity all require careful attention before the transaction closes.
Homeowners considering this type of transfer benefit most from working with a real estate attorney and a tax advisor together — when a real estate attorney is essential is a question worth answering before you commit to any structure.

Frequently Asked Questions
Does selling my house for $100 avoid probate?
A $100 sale transfers ownership immediately, which does remove the property from your probate estate. However, the gift tax filing requirement and Medicaid look-back rules still apply regardless of probate avoidance.
Can I sell my house to my son for $1 to avoid Medicaid clawback?
No. Medicaid’s five-year look-back period reviews all below-market transfers. Selling for $1 or $100 is treated the same — the difference between sale price and fair market value is counted as a disqualifying transfer.
Do I need a real estate attorney for a below-market family sale?
Yes. A real estate attorney ensures the deed is properly drafted, recorded, and legally defensible. They also identify state-specific disclosure requirements and title issues that could affect your son’s ownership rights later.
Will my son owe property taxes differently after a $100 sale?
Possibly. Some states reassess property taxes upon transfer of ownership, even between family members. Others offer exemptions for parent-to-child transfers. Check your state’s property tax reassessment rules before completing the sale.
Is a $100 home sale the same as gifting a house?
Functionally, yes. The IRS treats the difference between the sale price and fair market value as a gift. The legal structure differs — a sale requires a deed and consideration — but the tax treatment is nearly identical to an outright gift.
