Buy to let

How to apply for 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 need to be a UK resident aged between 18 and 70

    You need at least a 25% deposit, or 35% for any new build houses or flats

    You must be borrowing at least £25,000 over a minimum of 3 years

    Your maximum borrowing amount cannot exceed £3.5 million

    The property you wish to purchase, or remortgage to us, must be habitable and worth at least £50,000

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

    Please note, we cannot offer mortgage where the household will have or has multiple occupants, or multiple tenancies.

  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.

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.
