How to apply for a buy to let mortgage

We aren't currently offering buy to let mortgages directly through NatWest

We regularly review the mortgages we offer. Please check back at a later date, when we hope to be able to provide you with a buy to let mortgage.

Your steps to applying for a buy to let mortgage

  1. 1

    Find out if you're eligible

    The following criteria applies for NatWest buy to let mortgage applications:

    • You're a UK resident aged between 18 and 80
    • Your expected rental income to be at least 125% of your monthly interest payments
    • You have at least a 25% deposit, or 35% for any new build houses or flats
    • The property is worth at least £50,000
    • You're borrowing at least £25,000 over a minimum of 3 years
    • Your total aggregated borrowing with NatWest brands will be less than £3.5 million

    We will not consider multiple tenancies, Homes of Multiple Occupancy (HMO), bedsits, ‘Related Person’ tenancies, properties that fall under a selective licensing scheme or properties that will be used as a holiday home or holiday let

    You cannot apply for a buy to let mortgage with us if you do not meet the above criteria

  2. 2

    If you're remortgaging a buy to let property, check how much is left to pay on your mortgage

    Look at the latest mortgage statement you received from your current mortgage provider to see how much is left to pay.

    Your current provider might ask for an Early Repayment Charge. Check your paperwork to see whether they apply. If you haven't yet thought about how you will pay off your current mortgage early, read our mortgage repayment guide.

  3. 3

    Compare our mortgage rates

    Enter a few details into our mortgage calculator and we’ll show you all the NatWest mortgages that could be right for you, based on what you've told us.

    Thinking of borrowing more? No problem, it's easy to vary the amounts in the calculator.

  4. 4

    Get an indicative decision

    You’ll need to get an Agreement in Principle to see if we think we may be able to lend you the amount you require.

    This isn't a firm decision, but it’s the most accurate result we can give you without performing a full credit check. It won't take long and it won’t affect your credit score.

Before you apply

What you need to have

It will help if you have the following documents handy

Three months' worth of payslips and bank statements to work out your income, plus any loan or credit card statements to help work out your monthly expenses.

Eligibility info

We don’t currently offer buy to let mortgages for multi-party (three or more applicants), guarantor, Help to Buy, Right to Buy, or shared equity mortgages.

Credit checks

What is the difference between a soft and a full credit check?

When you apply for an Agreement in Principle, we'll need to do a “soft credit check”. But don’t worry, this won’t affect your credit score. If you go on to apply for a remortgage, we'll do a full credit check, which will show up on your credit file.
