Yes, someone can legally buy a house on your behalf, and there are four well-established ways to do it: they can sign for you under a power of attorney, give you the money as a documented gift, join you on the mortgage as a co-borrower or co-signer, or purchase the property through a trust. Which route fits depends on whose name should end up on the title, whose credit and income will qualify for the loan, and how the tax consequences land years down the road. The one rule that runs through all of them is transparency with the lender. Hide who is really buying or who will really live in the home, and a legal arrangement turns into federal mortgage fraud.
Signing for You Under a Power of Attorney
A power of attorney lets you (the principal) authorize someone else (the agent) to sign legal documents for you. In a home purchase, the agent can attend closing, sign the loan documents, and execute the deed in your name. You are still the buyer. Your credit and income qualify the loan, and you end up on the title as the owner.
Lenders and title companies almost always want a special or limited power of attorney rather than a general one. A special power of attorney names the specific property, identifies the lender, and spells out exactly what the agent can do. Fannie Mae’s selling guide, for example, requires the document to expressly identify the property and state an intention to secure a loan from a named lender. A general power of attorney grants broad authority over someone’s financial affairs, and lenders treat it as too open-ended.
One detail catches families off guard. A standard, non-durable power of attorney stops working the moment the principal becomes mentally incapacitated. If you are setting this up because a parent is aging or ill, you need a durable power of attorney, which stays in effect after the principal loses capacity. Otherwise the document can be worthless on the day it matters.
When the agent signs, they must sign in a representative capacity, using a form like “John Doe, as attorney-in-fact for Jane Smith.” That signature block is what attaches ownership and loan obligations to you rather than to the person holding the pen.
Someone Gives You the Money to Buy the Home
The most common way a family member helps is by giving money for the down payment or, sometimes, the entire purchase price. You are the buyer on paper and in fact. The lender simply needs to confirm the money is a real gift and not a hidden loan that would change your debt load.
What Lenders Require
Conventional mortgage lenders following Fannie Mae guidelines require a signed gift letter from the donor stating the dollar amount, that no repayment is expected, and the donor’s name, address, phone number, and relationship to you.1Fannie Mae. Personal Gifts Expect the lender to also want a paper trail: statements showing the money leaving the donor’s account and arriving in yours.
Not every donor is acceptable. Fannie Mae allows gifts from relatives (by blood, marriage, adoption, or legal guardianship), domestic partners, fiancés, and individuals with a long-standing family-like relationship with the borrower. The donor cannot be the builder, developer, real estate agent, or anyone else with a financial interest in the transaction.1Fannie Mae. Personal Gifts
Gift Tax Falls on the Giver
The donor, not you, handles any gift tax paperwork. In 2026, one person can give up to $19,000 per recipient without filing a gift tax return.2Internal Revenue Service. Whats New – Estate and Gift Tax A married couple can combine their exclusions and give up to $38,000 to the same person tax-free.
Gifts above $19,000 require the donor to file IRS Form 709, but filing is not the same as owing tax.3Internal Revenue Service. Instructions for Form 709 The excess reduces the donor’s lifetime estate and gift tax exemption, which sits at $15,000,000 for 2026.2Internal Revenue Service. Whats New – Estate and Gift Tax Most people who fund a home purchase for a family member end up filing the form and owing nothing.
If someone buys the entire home outright and puts it in your name, the IRS treats the full purchase price as a gift. The same rules apply, but the numbers involved almost always trigger the Form 709 requirement.
Going on the Loan With You: Co-Borrower vs. Co-Signer
Instead of gifting money, a parent or partner may join the mortgage application so that their income and credit help you qualify. There are two ways to do that, and they are not interchangeable.
Co-Borrower
A co-borrower is a full partner in the purchase. Their name goes on both the mortgage and the title. They share ownership and share responsibility for the debt. Lenders evaluate both people’s income, credit, and assets. This is the standard setup for couples or family members who both intend to actually own the home.
The catch is complete financial entanglement. Every late payment hits both credit reports. If the relationship breaks down, neither party can simply walk away, because both have a legal claim to the equity. Untangling co-ownership usually means selling or buying the other person out.
Co-Signer
A co-signer lends their credit to help you qualify but does not go on the title. They have no ownership interest and no claim to equity. They do carry full legal liability for the loan if you stop paying. This is how many parents help an adult child buy a first home.
FHA Loans and Non-Occupant Co-Borrowers
FHA loans handle this situation with a specific rule. If a non-occupant co-borrower is a family member, the standard FHA terms apply, with down payments as low as 3.5% at a credit score of 580 or higher. If the non-occupant co-borrower is not a family member, the FHA treats the deal more like an investment property and requires 25% down. On a $300,000 home, that is the difference between roughly $10,500 and $75,000.
Buying the Home Through a Trust
A trust is a legal entity that holds property for the benefit of designated people. When a home is bought through a trust, the trust appears on the deed as the owner. The person who creates it (the grantor) funds it and names a trustee to manage the property under the trust’s written terms for one or more beneficiaries.
The version most homebuyers use is a revocable living trust, where the grantor typically serves as both trustee and beneficiary during their lifetime. The main draw is probate avoidance. When the grantor dies, the property passes directly to a successor beneficiary without court proceedings, which can otherwise take months or years depending on the state.
If you already own a home with a mortgage and want to move it into a trust, the loan documents likely contain a due-on-sale clause. Federal law blocks the lender from enforcing it in this situation. The Garn-St. Germain Act prohibits lenders from calling a loan due when property is transferred into a trust, as long as the borrower remains a beneficiary and continues to occupy the home.4GovInfo. 12 USC 1701j-3 – Due-on-Sale Clauses That protection is one reason estate planning attorneys routinely recommend revocable living trusts.
Tax Consequences You Inherit With the House
The tax story does not end with the donor’s Form 709. The bigger issue is your cost basis, which the IRS uses to calculate your taxable profit when you eventually sell.
When you receive property as a gift, you generally inherit the donor’s original cost basis rather than a new basis equal to the home’s current market value.5Internal Revenue Service. Publication 551 – Basis of Assets Say a parent bought a home for $200,000 twenty years ago and gifts it to you when it is worth $500,000. Your basis is $200,000, not $500,000. If you later sell for $600,000, you owe capital gains tax on $400,000 of profit (minus any qualifying exclusions), not just the $100,000 of appreciation that happened on your watch.
Inheriting the same home at the donor’s death works very differently. Inherited property gets a stepped-up basis equal to its market value at the date of death, which wipes out all the unrealized appreciation. From a pure tax standpoint, that often makes inheritance more favorable than a lifetime gift. It is worth discussing with a tax professional before deciding how to structure the transfer.
Where Legal Help Becomes Mortgage Fraud
Every method above depends on the lender knowing the truth. A power of attorney discloses the principal. A gift letter documents where the money came from. A co-borrower or co-signer appears on the application. A trust hands over its governing documents. The lender can make an informed decision because it knows who is actually involved.
Two situations flip the arrangement into a federal crime.
The first is occupancy fraud. Lenders offer their best interest rates and lowest down payments to borrowers buying a primary residence. Investment property loans typically run a quarter to three-quarters of a percentage point higher, with substantially larger down payments. Claiming you will live in a home while actually intending to rent it out or leave it vacant induces the lender to offer terms it would not have approved. If someone is helping you buy a home you will not occupy, the correct move is an investment property loan, not a better rate obtained by lying on the occupancy certification.
The second is a straw buyer scheme. One person’s name and credit obtain a mortgage that another person, who cannot qualify, will actually benefit from. The lender never learns who is really behind the purchase. That concealment is the crime, whether or not anyone plans to make the payments.
Two federal statutes reach this conduct. Under 18 U.S.C. § 1344, executing a scheme to defraud a financial institution carries fines up to $1,000,000 and up to 30 years in prison.6Office of the Law Revision Counsel. 18 US Code 1344 – Bank Fraud Under 18 U.S.C. § 1014, knowingly making a false statement on a loan application to a federally connected lender carries the same maximum penalties.7Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally Beyond prosecution, the lender can call the loan due, foreclose, and pursue civil claims against everyone involved. Lenders have gotten considerably better at spotting these arrangements by cross-referencing tax returns, employment records, and post-closing occupancy checks.
Pick the route that matches what you actually want—a signer, a gift, a co-owner, or a trust—and put it on paper the way lenders and the IRS expect to see it. That is the whole difference between a family helping a family member into a house and a federal case.
