Sell your house subject to the existing mortgage

What "subject to" the existing mortgage means

Buying a house "subject to" the existing mortgage means the buyer takes ownership while the seller's loan stays where it is. The deed transfers to the buyer, but the loan is not paid off at closing and is not refinanced. The mortgage remains a lien on the property and the loan remains in the seller's name.

Usually the buyer agrees to make the monthly payments going forward, and may pay the seller some amount for their equity. Sellers often hear about subject-to when they owe close to what the house is worth, so a traditional sale would leave little or nothing after commissions and closing costs.

The most important thing to understand is what does not change: a subject-to sale does not transfer or eliminate your mortgage obligation. You signed the note, and you stay responsible for it until the loan is paid off or the lender formally releases you.

You stay liable, and your credit stays tied to the loan

The lender's agreement is with you. If the buyer pays on time, the loan is reported as paid on time. If the buyer pays late or stops paying, the late payments are reported on your credit, and the lender can pursue foreclosure on the house and, depending on state law, may seek a deficiency from you.

That is why the payment arrangement matters so much. Many sellers ask for a way to confirm each payment, such as online access to the loan account, a third-party servicing company, or regular statements, and for clear remedies in the agreement if a payment is missed.

The loan also stays on your credit report, which can affect your debt-to-income ratio and your ability to qualify for a new mortgage until the old one is paid off or refinanced.

The due-on-sale clause and the Garn–St Germain Act

Most mortgages contain a due-on-sale clause, which lets the lender require the full balance to be paid if the property, or an interest in it, is sold or transferred without the lender's consent. Federal law, the Garn–St Germain Depository Institutions Act (12 U.S.C. 1701j-3), generally allows lenders to enforce these clauses.

The same law lists transfers for which a lender may not use a due-on-sale clause on a loan secured by residential property with fewer than five dwelling units. A sale to an unrelated buyer or investor is not on that list.

Whether a lender actually calls a loan due is up to the lender. Some never notice or never act; others do. If the lender accelerates the loan, the full balance becomes due, and if it is not paid or refinanced, the lender can move toward foreclosure, with the loan and any damage to credit still in your name.

• A junior lien or encumbrance that does not relate to a transfer of rights of occupancy
• A purchase-money security interest for household appliances
• A transfer on the death of a joint tenant or tenant by the entirety
• A lease of three years or less with no option to purchase
• A transfer to a relative resulting from the borrower's death
• A transfer where the borrower's spouse or children become an owner
• A transfer to a spouse under a divorce decree, legal separation agreement or related property settlement
• A transfer into an inter vivos (living) trust in which the borrower is and remains a beneficiary, not involving a transfer of occupancy rights
• Any other transfer described in the federal regulations that implement the law

Insurance, escrow, taxes and title

Insurance is easy to get wrong. Once you no longer own the house, a homeowner's policy in your name may not respond the way you expect, and the lender requires the property to stay insured. The coverage needs to reflect the new owner and the interests of everyone involved, including the lender as mortgagee; talk to a licensed insurance agent before closing.

If your loan has an escrow account, property taxes and insurance are paid from it, and the escrow payment can change each year. The agreement should say who covers escrow increases or shortages, and what happens to the existing escrow balance.

Title matters too. The deed should be recorded, and a title company or real estate attorney can check for other liens, judgments or unpaid taxes and issue title insurance where available. Ask what happens to any other liens on the property and who is responsible for them.

Subject-to vs a formal loan assumption

A loan assumption is a different thing. In an assumption, the buyer applies to the lender, and the lender agrees to let the buyer take over the loan. Depending on the loan and the lender, the seller may be released from liability.

Some government-backed loans have assumption rules. FHA regulations limit restrictions on assumption but require a creditworthiness review of the person acquiring the property where the mortgage requires approval (24 CFR 203.512). For VA-guaranteed loans, federal law provides that a seller is relieved of liability to VA if the loan is current, the buyer qualifies, the buyer assumes the obligations, and the holder is notified in writing before the transfer (38 U.S.C. 3714).

A subject-to sale skips the lender's approval entirely. That is faster and avoids qualification, but it is also why the seller stays liable and the due-on-sale clause remains a live issue. If an assumption is available for your loan, it is worth asking your servicer about it.

Risks for the seller

The risks in a subject-to sale fall mainly on the seller, because the seller keeps the debt while giving up the house. Some can be managed with good paperwork and verification; none can be eliminated entirely.

Before agreeing, picture the worst realistic case: the buyer stops paying two years from now, the house has lost value, and the lender is sending notices to you. If that outcome would be unmanageable, a sale that pays the loan off is likely the better choice.

• The buyer pays late or stops paying, and your credit is damaged.
• The lender calls the loan due under the due-on-sale clause.
• Foreclosure happens on a loan still in your name.
• Insurance gaps leave the property, or you, exposed after a loss.
• Escrow shortfalls or tax delinquencies are not covered.
• The open loan makes it harder to qualify for your next mortgage.
• Disputes arise over who pays for repairs, HOA dues or other obligations.

Protections sellers commonly ask for

If you are considering a subject-to sale, have your own real estate attorney review the documents. Sellers often ask for independent payment verification, a deadline by which the buyer must refinance or pay off the loan, proof of insurance listing the right parties, and clear remedies if payments are missed.

Also ask how and when the loan will be paid off. A subject-to arrangement with no plan for ending your liability leaves you exposed for as long as the loan exists, which may be decades.

When a cash sale or a loan payoff is the cleaner route

A cash sale pays off your mortgage at closing. The lien is released, the loan is closed, and your liability for it ends. If you have enough equity to cover the payoff, a cash sale or a traditional listing is usually the cleaner path, even if the amount you walk away with is modest.

If you owe more than the house is worth, a short sale negotiated with your lender, a loan modification, or talking to a HUD-approved housing counselor may be worth exploring before a subject-to arrangement. Subject-to may make sense for some sellers in specific circumstances, but it should be a deliberate choice made with full knowledge of the risks, not a default.
