Repayment vs interest-only, what’s the difference?

Your mortgage repayment type determines how your monthly payment is structured. There are two main options: repayment (also called capital and interest) and interest-only. The vast majority of residential mortgages are on a repayment basis, but understanding the difference is important, particularly for buy-to-let investors.

Repayment (capital & interest) mortgages

A repayment mortgage means each monthly payment covers both the interest charged by the lender and a portion of the outstanding loan. Over time, the balance reduces until it reaches zero at the end of the term. You’re guaranteed to own your home outright at the end, assuming you make all payments.

Why Choose Repayment

You gradually reduce your debt with every payment. At the end of the term, your mortgage is paid off and you own your property outright. The most secure long term approach for residential buyers.

How Payments Work

Monthly payments are higher than interest-only but your balance reduces over time. In early years, most of the payment is interest, this shifts to mostly capital in later years.

Interest-only mortgages

With interest-only, your monthly payment covers only the interest, the capital balance stays the same throughout the term. At the end of the mortgage term, you still owe the original loan amount and must repay it in full (from savings, sale of the property, or another source).

Lower Monthly Payments

Monthly payments are significantly lower than on a repayment mortgage, improving cash flow. Commonly used for Buy to Let investments to maximise monthly yield.

Repayment Plan Required

For residential interest-only, lenders require a credible repayment vehicle (ISA, pension, investments, or planned property sale). Harder to qualify for residential use.

Part & Part

Some lenders allow a split: part repayment and part interest-only. This reduces monthly payments while ensuring a portion of capital is paid down. Useful for cash flow management.

Which repayment type suits you?

For most residential homeowners, repayment is the right choice, you build equity and own the property at the end. Interest-only is most commonly used for Buy to Let, where cash flow and yield are the priority and the property itself forms part of the repayment plan.

Residential interest-only: Lenders have tightened criteria significantly since the 2008 financial crisis. Most require a clear repayment vehicle, higher equity (lower LTV), and proof of income. Speak to us about whether you qualify.
