Buy-to-let mortgage on inherited property: what happens to the loan
Published · Updated
A buy-to-let mortgage on inherited property is a debt of the estate: it doesn't disappear when the borrower dies, and it is deducted from the estate's value for Inheritance Tax [1]. GOV.UK tells the person dealing with the estate to ask the lender whether payments must continue while probate is applied for, and if so to pay them and reclaim them later, or check for a life or mortgage protection policy [1].
Tell the lender quickly. Keep payments up if the lender requires it, using the rent if there's a tenant [1]. The mortgage reduces the taxable estate [1]. When the property passes to you, the lender will usually want the loan repaid or replaced, typically by selling the property or by you taking out your own mortgage; lenders set their own rules, so ask early. If you keep the property in your own name, mortgage interest isn't deducted from your rent; you get a 20% tax reduction instead [2]. A lender can also seek possession on a ground for missed payments, with four months' notice to the tenant [3].
General information only. Lenders' policies vary and this isn't financial advice.
The first call: the lender
Write to the lender with a copy of the death certificate. Ask:
- Do payments need to continue during probate?
- Is there any life or mortgage protection cover on the loan?
- What's the redemption figure at the date of death? (You'll need it to value the estate [1].)
- What options does the lender offer to a beneficiary who wants to keep the property?
- How long will the lender wait before expecting repayment?
Keep the replies in one file. If the estate has more than one mortgaged property, keep a separate thread for each loan.
Buy-to-let mortgage on inherited property: how it affects Inheritance Tax
Mortgages are debts that you must tell HMRC about if you report the estate [1]. They reduce the value of the estate on which Inheritance Tax is worked out. For example:
| Item | Value |
|---|---|
| Rental property | £300,000 |
| Buy-to-let mortgage outstanding | minus £170,000 |
| Net value of the property in the estate | £130,000 |
The mortgage also matters for the 40% rate, which only applies to the part of the estate over the threshold [4]. A heavily mortgaged portfolio can have a much smaller taxable value than its headline property values suggest.
Who pays the mortgage during probate?
The estate. In practice, there are three ways it gets paid:
| Source | How |
|---|---|
| The rent | If the property is let, the rent collected by the executor covers the payment |
| The deceased's accounts | Banks may release funds to pay certain bills, but often need the grant |
| A family member | GOV.UK says you can pay the bills yourself and reclaim from the estate after probate [1] |
If payments stop and the lender takes action, the tenancy doesn't protect the property from the lender. Since 1 May 2026, the grounds for possession include one a lender can use to get possession to sell if mortgage payments are missed, with four months' notice to the tenant [3].
Options once the property passes to you
1. Sell the property and repay the loan
The simplest route for many. The sale price clears the mortgage and selling costs; the rest is yours (or the estate's). If the sale price is above the value at death, Capital Gains Tax may be due on the increase, reported within 60 days [5][6].
2. Take out your own buy-to-let mortgage
You apply to a lender in your own right and the new loan repays the old one. Your lender will look at your income, the rent and the property. Plan for this early, because the existing lender may not wait indefinitely.
3. Pay off the mortgage from other inheritance
If the estate includes cash, the will or the beneficiaries' agreement can use it to clear the mortgage before the property is transferred.
4. Inherit with siblings and refinance together
Where several people inherit, the lender will look at all the borrowers. If one sibling wants to buy the others out, they'll need to borrow enough to pay both the mortgage and the others' shares. See our siblings guide.
Tax on the mortgage interest once you're the landlord
If you own the property personally, you can't deduct residential mortgage interest from your rent. Since 6 April 2020, individual landlords get a tax reduction worth 20% (the basic rate) of the lower of their finance costs, property profits or adjusted total income [2]. Companies are different: a company paying Corporation Tax "can claim interest on property loans as an allowable expense" [7]. See our section 24 guide and limited company guide.
Worked example
Daniel inherits a flat with £1,050 a month rent and a buy-to-let mortgage of £120,000 at 5% interest only. He's a higher-rate taxpayer.
| Line | Annual |
|---|---|
| Rent | £12,600 |
| Other allowable expenses | minus £1,800 |
| Taxable property profit (interest not deducted) | £10,800 |
| Tax at 40% (assuming all of it falls in the higher-rate band) | £4,320 |
| Mortgage interest | £6,000 |
| Basic-rate reduction (20% of £6,000) | minus £1,200 |
| Tax on the flat | £3,120 |
| Cash left after interest and tax | £1,680 |
The basic-rate reduction is limited by the "lower of" test and can carry forward if unused [2]. Use our section 24 guide to check your own figures.
Insurance and the lender's conditions
Most buy-to-let mortgages require landlord buildings insurance and that the property is let on the terms the lender allows. GOV.UK says that if you have a mortgage on a property you want to rent out, you must get the lender's permission [8]. If you inherit a house without a buy-to-let mortgage, perhaps a residential mortgage on the deceased's own home, and want to let it, ask the lender before anyone moves in.
A timeline for an inherited mortgaged rental
| When | Action |
|---|---|
| Week 1 | Death certificate to lender; ask about payments and cover |
| Month 1 | Redemption figure for valuation; payments set up from rent |
| Month 6 | Inheritance Tax due by end of the sixth month after death [9] |
| Probate granted | Decide: sell, refinance, or clear from other assets |
| After transfer | New mortgage in your name, or sale completes |
If the estate is short of cash
Mortgaged portfolios often have little spare cash, and Inheritance Tax, mortgage payments and repairs can all fall due before probate. Options set out by GOV.UK:
- Pay Inheritance Tax on the property in instalments. Tax on land and buildings, including let property, can be paid in equal yearly instalments over 10 years as long as you don't sell [9][10]. Interest usually applies to later instalments [10].
- Use the deceased's bank accounts. Under the Direct Payment Scheme, banks can pay Inheritance Tax straight to HMRC before probate [9].
- Postpone. If you can't release funds and can't pay another way, you can ask to postpone paying Inheritance Tax [9].
- Pay and reclaim. Family members can pay the mortgage and reclaim from the estate once probate is granted [1].
Documents a new lender will usually ask for
If you plan to refinance in your own name, gather these early:
| Document | Where to find it |
|---|---|
| Grant of probate or letters of administration | Probate registry [11] |
| Current tenancy agreement and rent statements | Deceased's files, agent, or Gaffy vault |
| Gas safety record, EICR, EPC | Deceased's files or contractor |
| Redemption statement on the existing loan | Existing lender |
| Your proof of income | Your own records |
Questions to settle with the other beneficiaries
If more than one person inherits, agree in writing before probate is granted:
- Will the mortgage be paid from rent, from estate cash, or by one of you (and reclaimed later [1])?
- Is the plan to sell, or for one beneficiary to refinance and keep the property?
- Who deals with the lender and who receives its letters?
- If one beneficiary takes on a new mortgage, at what value are the others' shares bought out?
Clear answers early stop the lender's timetable from forcing a decision nobody wanted.

Check the person's papers and ask the lender [1].
