Inherited House With a Mortgage: Can the Lender Call the Loan?

The lender’s right, and the nine events it cannot use

Most mortgages carry a due-on-sale clause, a contract term that lets the lender declare the loan due if the property is transferred without its consent. The Garn-St Germain Depository Institutions Act of 1982 defines it in 12 U.S.C. 1701j-3(a)(1) as a provision that “authorizes a lender, at its option, to declare due and payable sums secured by the lender’s security instrument if all or any part of the property, or an interest therein, securing the real property loan is sold or transferred without the lender’s prior written consent.” Subsection (b)(1) lets a lender enforce it despite state law, and (b)(2) leaves the exercise to the contract “except as otherwise provided in subsection (d).”

Subsection (d) is the list that matters to an heir. It applies to “a real property loan secured by a lien on residential real property containing less than five dwelling units” (the statute adds cooperative stock and manufactured homes), and says the lender “may not exercise its option pursuant to a due-on-sale clause upon” nine events. Three bear on death: (3) “a transfer by devise, descent, or operation of law on the death of a joint tenant or tenant by the entirety”; (5) “a transfer to a relative resulting from the death of a borrower”; and (6) “a transfer where the spouse or children of the borrower become an owner of the property.” Item (8) protects a lifetime transfer into a living trust, the subject of our guide to deeding real estate into a living trust.

Nothing in these items asks whether the relative lives in the house. That condition comes from the regulation.

The occupancy gap: statute, regulation and Fannie Mae

The implementing rule, 12 CFR 191.5, is the Office of the Comptroller of the Currency’s; paragraph (a) says that due-on-sale practices “of Federal savings associations and other lenders” are governed by it. Paragraph (b) begins “With respect to any loan on the security of a home occupied or to be occupied by the borrower,” and its relative item reads: “A transfer, in which the transferee is a person who occupies or will occupy the property, which is: (A) A transfer to a relative resulting from the death of the borrower; (B) A transfer where the spouse or child(ren) becomes an owner of the property.” The joint-tenant item, 191.5(b)(1)(iii), has no occupancy condition. The rule also leaves out a reverse mortgage (“except with regard to a reverse mortgage”).

Our reading: for an heir who lives in the house, all four sources point the same way. For an heir who does not, the statute text has no occupancy condition, the regulation does, and Fannie Mae’s own guide drops it for loans from June 1, 2016 onward. The texts we saved do not say which controls for an older loan owned by another investor, and we found no case in them. The practical step is to ask the servicer in writing which investor owns the loan and how it treats the transfer. Our page on assumable mortgages explains why the regulation’s occupancy language matters for investors.

Two more passages in 12 CFR 191.5 matter to an heir. Paragraph (b)(2) says a lender “shall not impose a prepayment penalty or equivalent fee” when it declares the loan due under a due-on-sale clause or starts foreclosure to enforce it. Paragraph (b)(5) cuts the other way: the exemptions do not restrict the lender “upon the subsequent occurrence of any event which disqualifies a transfer for a previously-applicable exception.”

Transfer type by transfer type: can the lender call the loan?

A note on the DSCR row. Subsection (d) is written by property type, not by the borrower’s purpose, and a one-to-four-unit rental is residential real property. But 12 CFR 191.5(b) speaks of “a home occupied or to be occupied by the borrower,” an LLC cannot die, and the death of a member is not itself a transfer of the property. We did not find a passage in the saved texts that settles an investor loan; treat the contract as the starting point.

What a successor in interest gets from the servicer

Regulation X, which implements the Real Estate Settlement Procedures Act, defines the term in 12 CFR 1024.31. A “successor in interest” is “a person to whom an ownership interest in a property securing a mortgage loan subject to this subpart is transferred from a borrower,” provided the transfer is one of five kinds: (1) “by devise, descent, or operation of law on the death of a joint tenant or tenant by the entirety”; (2) “to a relative resulting from the death of a borrower”; (3) one where the spouse or children become an owner; (4) a divorce or separation transfer; or (5) into a trust where the borrower remains a beneficiary. Regulation Z, 12 CFR 1026.2(a)(27), uses the same five items for a “dwelling securing a closed-end consumer credit transaction.” Neither definition mentions occupancy.

The Consumer Financial Protection Bureau’s 2013 bulletin on this duty (CFPB Bulletin 2013-12) described the problem the later rule addressed: servicers “demanding documents to prove the successor in interest’s claim to the property that either do not exist (e.g., probate court documents for an estate that is not required to go through probate) or are not reasonably available.” It listed as a reasonable practice giving a claimant a list of documents that “might include, for example, a death certificate, an executed will, or a court order determining a succession to real property.” The rule text itself leaves the list to the servicer, so what to send depends on the reply to your first letter. Our guide to probate and real estate covers when a court order is needed at all.

Does the lender have to let you keep the loan?

Not under the Garn-St Germain list, which stops the lender from calling the loan but does not oblige it to put you on the note. The statute says a lender “is encouraged to permit an assumption of a real property loan at the existing contract rate” (12 U.S.C. 1701j-3(b)(3)). On July 17, 2014 the CFPB published an interpretive rule (79 FR 41631) saying that where a successor who has already acquired title is added as obligor, the creditor’s written acknowledgment is “not subject to the Bureau’s Ability-to-Repay Rule” because it is not an assumption under Regulation Z. The Bureau wrote that in these situations “the successor is not personally liable for the associated debt, but may choose to assume the debt,” and that “creditors may agree to add the successor as a named obligor.” So a servicer can add an heir without a new income test; whether it will is for the servicer and the investor that owns the loan. A successor who wants a modification may need to be on the note first, a problem the 2014 notice itself describes.

Worked example: two siblings, a $420,000 house, a $160,000 loan (our arithmetic)

Assumptions, all ours: the house is worth $420,000 at the date of death; the balance is $160,000 on a fixed 3.1% loan with 22 years (264 months) left; two siblings inherit equally; neither lives there. The 6% sale cost and the 6.5% comparison rate are illustrations, not quotes.

What the arithmetic shows. The 3.1% loan is cheap money: $304 a month less than the same balance at an assumed 6.5%, or $3,648 a year, and the remaining interest to maturity is about $60,913 against about $141,145 at 6.5%. Whether that is worth keeping depends on whether the siblings can carry a house they do not live in, and on whether one wants to buy out the other. A buyout moves title from one heir to another, and 12 CFR 191.5(b)(5) says an event that disqualifies a transfer restores the lender’s right, so ask the servicer in writing before recording that deed.

The basis, which the siblings can document with a date-of-death appraisal, does most of the tax work. The step-up applies to the whole $420,000, not to the $260,000 of equity: the statute says the basis is “the fair market value of the property at the date of the decedent’s death,” with no subtraction for debt (our reading). A sale within one year of the death is treated as long-term (26 U.S.C. 1223(9)), so a quick sale at $420,000 has no gain, and even a sale at $450,000 shows only $3,000 of gain after the same 6% costs of $27,000 (our arithmetic: $450,000 less $27,000 less $420,000). Our page on the step-up in basis for inherited real estate covers the valuation date and the estate tax return.

Interest, rent and the tax return

Federal tax rules let an owner deduct mortgage interest without being on the note: 26 CFR 1.163-1(b) says interest paid by the taxpayer “on a mortgage upon real estate of which he is the legal or equitable owner, even though the taxpayer is not directly liable upon the bond or note secured by such mortgage, may be deducted as interest on his indebtedness.” What kind of deduction it is depends on how the house is used.

If an heir moves in and later sells, the home-sale exclusion in 26 U.S.C. 121(a) requires that the property have been “owned and used by the taxpayer as the taxpayer’s principal residence for periods aggregating 2 years or more” in the five years before the sale. The heir’s own use is what counts. For rentals, depreciation starts from the stepped-up basis; see our rental depreciation calculator.

Decision points for an heir

• Keep paying while you sort out the paperwork. An exempt transfer protects you from acceleration, not from default. A lender with a security interest still has “a right to foreclose” if payments stop (12 CFR 1024.32(c)(1)(ii)).
• Write, do not phone. A written request under 12 CFR 1024.36(i) starts the 30-day clock and creates a record.
• Ask who owns the loan. The occupancy question turns on whether Fannie Mae owns or securitized it on or after June 1, 2016. After confirmation the servicer must give the owner’s identity within 10 days (12 CFR 1024.36(d)(2)(i)(A)).
• Decide who will be on the note. You can stay a non-liable owner who pays, ask to be added as obligor (the 2014 interpretive rule removes the ability-to-repay test, not the servicer’s discretion), refinance, or sell.
• If the house is shared, plan the title before the loan. Heirs who cannot agree face a different problem; see our guide to partition actions and heirs’ property.
• If the loan is on five or more units or in an LLC’s name, read the transfer clause now. The federal exemptions on this page are not written for that loan.

What a reader can do with this

• Write the first letter. Name the deceased borrower, give the loan number, say you may be a successor in interest, and ask for the list of documents under 12 CFR 1024.36(i). Keep the date you mailed it.
• Order a date-of-death appraisal before the house is cleaned out or repaired. It supports the basis in 26 U.S.C. 1014(a)(1).
• Ask the servicer three questions in the same letter: who owns the loan, whether it treats the transfer as exempt, and whether it will add you as obligor.
• Put your own numbers into the example table: balance, rate, months left, payment, and what the same balance would cost at today’s rate. The gap is what you give up by selling.
• Check the use of the house before the return, because the same interest is a rental expense in one case and possibly personal interest in another.
