Buy to Let Interest Only
What is a Buy to Let Interest-Only Mortgage?
A buy-to-let interest-only mortgage is designed for landlords looking to purchase a rental property as an investment. With this type of mortgage, your monthly payments cover only the interest on the loan amount, meaning your payments are typically lower than they would be with a repayment mortgage.
However, the capital debt (the amount borrowed) remains unchanged throughout the mortgage term unless you choose to make extra repayments. At the end of the term, the full loan amount must be repaid, which can be done by selling the property, refinancing, or using other funds. This option may suit landlords seeking to maximise cash flow or those planning to sell the property for a profit at the end of the term.

Eligibility Criteria for Buy to Let Interest-Only Mortgages
Eligibility for a buy-to-let interest-only mortgage depends on your rental income, deposit size, and personal circumstances. Lenders typically require that your rental income exceeds the monthly mortgage repayments by a specific margin, usually between 125% and 140%.
While criteria vary by lender, some general requirements include:
- A minimum annual income of £25,000
- A minimum age of 21 (with some lenders also having an upper age limit)
- Being a homeowner (many lenders do not accept first-time buyers)
- A deposit of 15%-25% of the property value (though higher deposits often secure better rates)
Additionally, as a landlord, Tax relief on mortgage interest is subject to current regulations. We recommend consulting a qualified tax adviser for advice specific to your situation. For specific advice on tax matters, we recommend consulting a qualified accountant.
Finding the Best Buy to Let Interest-Only Mortgage Deals
Interest-only mortgage rates for buy-to-let properties are generally higher than standard residential rates, reflecting the perceived higher risk of tenants compared to owner-occupiers. However, putting down a larger deposit, closer to 25% of the property value, can increase your chances of securing better rates.

Repayment Strategies for Buy to Let Interest-Only Mortgages
When your mortgage term ends, you’ll need to repay the full loan amount as you’ve only been paying interest. It’s essential to have a clear repayment strategy in place from the start, whether that involves selling the property, refinancing, or using personal savings.
Many landlords plan to sell their rental properties at the end of the term, ideally at a higher value than the purchase price, to repay the loan and potentially make a profit. Whatever your repayment plan, it’s important to review it regularly to ensure it remains achievable.
