Buy-to-let mortgages

A buy-to-let mortgage is for a property you intend to rent out rather than live in. Lenders assess it on the rent it will earn as well as on you.

Demand for rented homes is strong and a well-chosen property can be a sound investment, but the mortgage works differently. Lenders look at the expected rent against the interest, usually want a bigger deposit, and many offer interest-only terms.

We arrange buy-to-let mortgages for first-time landlords, people moving out and letting their old home, and investors building a portfolio, including purchases through a limited company.

How it works

Buy-to-let, step by step

  1. Rental assessment

    We check the rent the property should achieve against the lender's stress test before you commit.

  2. Structure

    Personal name or limited company, repayment or interest only, and how it fits any other properties you own.

  3. Application

    We submit to a lender that suits your situation and manage it through to offer.

  4. Protect the investment

    Landlord insurance and rent guarantee options arranged alongside, so the property is covered from day one.

These figures are for illustration only. They are not a quote, an offer or advice. The rate and the amount you could borrow depend on your circumstances and on the lender.

Your home may be repossessed if you do not keep up repayments on your mortgage.

Good to know

Buy-to-let questions

How much deposit do I need for a buy-to-let?

Usually at least twenty to twenty-five per cent of the purchase price. A larger deposit improves the rate and makes the rental calculation easier to pass.

How do lenders decide how much I can borrow?

Mainly on the rent. Most want the monthly rent to cover the mortgage interest by a margin, typically 125 to 145 per cent at a stressed rate, and many also apply a minimum personal income.

Should I buy through a limited company?

It depends on your tax position and plans. Company mortgages can carry higher rates and fees but the tax treatment of interest differs. We explain the mortgage side and your accountant advises on tax.

How much does WeSure charge?

Our broker fee starts from £495 and depends on your circumstances. We tell you the exact figure before you commit to anything, and lenders may also pay us a procuration fee, which we disclose.

Does asking for a quote affect my credit score?

No. Talking to us and getting an idea of what you could borrow involves no credit search. A lender only runs a search when you decide to apply, and we tell you before that happens.

Do you cover the whole of the UK?

We are based in London and advise clients across England, Wales, Scotland and Northern Ireland by phone and video. Most of the process happens online, so where you live rarely matters.
