FHA loan assumption rules and qualifying

What an assumption is

The Handbook defines an assumption in one sentence: it is the transfer of an existing mortgage obligation from an existing borrower to the assuming borrower. Nothing about the interest rate, the remaining balance or the monthly payment changes, because the new borrower steps into the old loan as it stands. That is the reason people search for the topic. A loan taken out at a lower rate than today's market can pass to a buyer, and the buyer inherits that rate. The rules below decide who is allowed to take that step and what the lender must do before agreeing.

Occupancy: the 1989 line

The first test is how the new borrower will use the home, and it depends on when the original mortgage closed. If it closed on or after December 15, 1989, the person assuming it must intend to occupy the property as a principal residence or as a HUD-approved secondary residence. If it closed before December 15, 1989, the assuming borrower may take it on as a principal residence, a HUD-approved secondary residence or an investment property. For a loan that closed after that date the practical meaning is simple: an FHA assumption is for someone who will live in the house, not for a landlord. The calculator above applies this test first.

Loan-to-value limits for non-owner use

Two limits apply when the property is not the new borrower's main home. For an investment property the maximum loan-to-value ratio is 75 percent. For a HUD-approved secondary residence it is 85 percent. In both cases the lender may measure against either the original appraised value or a new property value, whichever is used to check compliance. Notice that the Handbook sets these limits only for those two uses. For a principal residence it states no loan-to-value ceiling in this section, and it adds that the assuming borrower is not required to make a cash investment: the borrower may assume 100 percent of the outstanding principal balance, subject to the two limits above.

A worked example

Suppose the outstanding balance is $180,000 and the home is valued at $200,000 for the purpose of the test. The ratio is 90 percent. As a principal residence it passes, because no ceiling applies. As a secondary residence it fails the 85 percent limit, and as an investment property it fails the 75 percent limit. To satisfy the secondary-residence limit with the same value the balance would have to be $170,000 or less, and for the investment limit $150,000 or less. These numbers are an illustration of the arithmetic, not a statement of what any lender will approve; type your own occupancy and ratio into the checker to see the same logic.

How the lender processes it

Three steps stand out. First, the lender must tell HUD through FHA Connection within 15 days of any change of borrower, or within 15 days of learning of a transfer of ownership. That notice by itself does not release the original borrower from the promissory note. Second, release happens through form HUD-92210.1, Approval of Purchaser and Release of Seller, which the lender prepares when the assuming borrower signs an agreement to assume the mortgage and pay the debt. Third, a direct endorsement underwriter registered by the lender in FHA Connection must complete the review. If the lender does not originate loans or lacks direct endorsement authority, an authorized agent may do the review.

Credit review and its exceptions

The new borrower is underwritten under the same Handbook rules as a purchase, with a list of exceptions that do not apply: ordering a case number or appraisal, transferring or updating an appraisal, property eligibility criteria, statutory and nationwide loan limits, underwriting the property, and underwriting with the TOTAL Mortgage Scorecard. The scorecard must not be used at all, so an underwriter reviews the file by hand. One narrow exception removes the credit review. If the transfer is by devise or descent, or in another situation where the transfer cannot legally trigger the due-on-sale clause, such as a divorce in which the person staying on title keeps occupancy, the lender may process the assumption without a credit review. That borrower must show they made the mortgage payments for at least six months before applying.

Fees and who may pay them

The lender may charge the assuming borrower a reasonable and customary processing fee that does not exceed $1,800, plus other allowed costs described elsewhere in the Handbook. The seller or other interested parties may contribute toward the assuming borrower's actual closing costs, within the Handbook's interested party contribution rules. The $1,800 figure is stated in the section without a year attached, so confirm it with the servicer; it is a cap on one fee, not an estimate of the total cost of assuming.

Limits of this page

This page covers the Handbook's assumption section for forward mortgages. It does not tell you whether your servicer is currently accepting assumption requests, how long one takes, whether your particular loan has a restriction in its own documents, or how a court order in a divorce interacts with title. It also does not compute the equity the seller may need to cover, since a buyer who assumes a loan still has to fund the difference between the purchase price and the remaining balance. For loan size ceilings see the FHA loan limit page, and to see what mortgage insurance would cost on an FHA loan use the FHA MIP calculator.
