Buy-to-let mortgages explained

A mortgage designed around a rental property

Buy-to-let finance is secured against a property intended for tenants. Unlike a standard residential mortgage, the expected rent is central to how lenders assess the borrowing.

The lender will still consider the applicant, deposit, property and ownership structure. Many products are interest-only, so the original capital remains due at the end and needs a credible repayment plan.

One market, different landlord journeys

Advice that starts with how you plan to invest

Experience, portfolio size, ownership and property type can all change the suitable lender. We research the case in context, rather than treating every let as the same.

Growing

Experienced landlords

Purchase or refinance with the wider portfolio, future plans and overall leverage in view.

Existing property performance can form part of the assessment.

At scale

Portfolio landlords

Navigate lenders with the appetite, systems and criteria to assess multiple mortgaged properties.

Portfolio schedules and supporting documents need careful preparation.Read the use-case guide

Ownership route

Limited company & SPV

Explore lender options for an eligible company structure while keeping mortgage advice separate from tax advice.

Independent tax and legal advice should shape the ownership decision.Read the use-case guide

Specialist property

HMO & multi-unit

Research specialist criteria where the property, tenancy or valuation falls outside a standard single let.

Licensing, experience and property configuration may affect availability.

Rental-led affordability

The rent needs to work on paper, not only in the listing

Lenders usually apply an interest coverage ratio to a stressed mortgage payment. The exact calculation varies, and the valuation rent may differ from the advertised or current rent.

ICR
Interest coverage ratio

A lender's test comparing expected rent with a stressed interest payment. It is a lending test, not a forecast of profit.

Expected rent

The valuer’s market rent and the lender’s own coverage calculation.

Deposit & LTV

Your contribution, property value and total borrowing required.

Applicant position

Income, commitments, credit profile and landlord experience.

Property

Type, condition, location, value, tenure and intended occupancy.

Portfolio

Existing balances, rent, values and the performance of other lets.

Ownership

Personal name, eligible company structure and relevant guarantees.

Personal or limited company?

Choose the structure before the mortgage

Ownership affects the borrower, application and available lenders. It can also have tax and legal consequences, so the cheapest-looking mortgage should not decide the structure.

Mortgage advice is not tax or legal advice.

Tax treatment depends on individual circumstances and may change. Speak to a qualified tax adviser and solicitor before choosing or changing how a property is owned.

Look beyond the monthly rent

Build the costs and quiet months into the plan

Lender affordability is only one test. A resilient investment plan also allows for purchase costs, maintenance, compliance, void periods and the eventual repayment of capital.

Purchase taxes

Higher rates or surcharges may apply to additional property purchases, with different systems across the UK.

Mortgage costs

Deposit, interest, product fees, valuation, legal work and adviser charges all affect the real cost.

Running the property

Insurance, repairs, safety requirements, licensing, agents and service charges need space in the budget.

Voids & resilience

Allow for empty periods, unexpected work and changes to mortgage payments rather than relying on full occupancy.

Buy-to-let mortgage FAQs

Useful answers for landlords and investors

These answers are general. Lender policy, regulation and tax treatment depend on the property and your circumstances.

Ask a landlord mortgage question

A buy-to-let mortgage is borrowing secured against a property that is intended to be rented to tenants rather than occupied as your own home. Lenders normally assess the expected market rent, property, deposit and applicant or company position. It should not be used to purchase a home for you to live in.

Your property may be repossessed if you do not keep up repayments on a mortgage or other debt secured on it.

Most buy-to-let mortgages are not regulated by the Financial Conduct Authority. Some buy-to-let mortgages, such as those involving close family occupation, may be regulated differently.
