What is a Buy to Let remortgage?

Remortgaging a Buy to Let is when you switch to a new mortgage on a property you rent out. It could involve moving to a different lender or staying with your current lender and getting a new deal (referred to as a product transfer).

What are the benefits of remortgaging a Buy to Let property?

There are a numbers of reasons for remortgaging a Buy to Let property. These include:

1. Saving money

Remortgaging when your current Buy to Let mortgage deal ends could save you thousands of pounds a year on your mortgage payments. The amount you can save will depend on the rate on your current Buy to Let mortgage deal vs the mortgage rate you can get.

If you’re coming off a cheap fixed rate mortgage in 2025, your new Buy to Let mortgage is likely to cost you more than your current one. But remortgaging could still save you money because if you do nothing and end up on your lender’s standard variable rate it could cost you significantly more.

If your current mortgage deal ends in the next 6 months, and certainly if it ends in the next 4 months, you should get mortgage advice.

How to remortgage a Buy to Let

Remortgaging a Buy to Let is a similar process to switching to a new deal on a residential mortgage:

  1. You’ll start by needing to know what Loan to Value (LTV) you’re looking for. For example, if your rental property is worth £300,000 and you need to borrow £150,000, your LTV is 50%. The lower the LTV, the wider the range of mortgages you’ll typically get access to. And you’ll usually get better rates too.
  2. The next step is to start shopping around for the best mortgage deal. This is something a mortgage broker can help you with.
  3. And remember, when you remortgage, you’ll go through the same financial scrutiny as when you applied for your current mortgage. This includes a full credit check and affordability assessment.

However, when it comes to Buy to Let mortgages, lenders will view your application differently than if you were applying for a residential mortgage. This is because the amount you can borrow is based on how much rent the property can generate compared to the cost of the mortgage. Lenders will look for the expected rental income to meet at least 125% of the monthly mortgage payments. For some lenders this figure is at least 145%. Bear in mind lenders may also require you to have a minimum salary too, usually £20,000 to £25,000. Find out how much you can rent your property for with our rent calculator.

How long does it take to remortgage a Buy to Let?

We recommend starting the process of remortgaging your Buy to Let around six months before your current deal ends. This will give you plenty of time to speak to a mortgage broker and consider your options. The next step is to apply for the mortgage you’ve chosen. It then typically takes four weeks from the date you receive your mortgage offer for your Buy to Let mortgage to complete, according to our partners at award-winning mortgage brokers L&C.

If the property is leasehold it can take a bit longer to remortgage, usually around six weeks from your mortgage offer date, as extra information will be needed by your conveyancer.

Can I change my mortgage to a Buy to Let?

There are various reasons for wanting to let out your property. These include moving in with a partner, relocating because of work, going travelling or wanting to buy a new home but still keep your current one as a long-term investment.

If you are planning to move out of your property and let it out, you’ll have three main options:

  • Obtain consent to let from your current lender. This doesn’t involve remortgaging; it allows you to let your property while maintaining your current mortgage. But your lender may introduce some new terms and conditions.
  • Remortgage onto a Buy to Let product: This means switching from a residential mortgage to a Buy to Let mortgage. However, as we explain above, it’s important to realise that with Buy to Let mortgages, lenders assess your affordability differently, compared to residential mortgages. This is because they will look at how much monthly rental income you’ll achieve when deciding whether and how much to lend.
  • Let to buy: with this option you can let your current property out to tenants and take out a new “Let to Buy”mortgage to buy your next home.

Can I be refused a Buy to Let remortgage?

Just because you currently have a Buy to Let mortgage doesn’t mean you’re guaranteed to get a deal from a new lender. There are various reasons for this. For example, if you have a low credit score. And if the property has a short lease, of 80 years or below, you may find it harder to remortgage.

However just because one lender has turned you down, doesn’t mean you won’t be accepted elsewhere. This is because each lender has a different lending criteria. This is why it can be helpful to use a mortgage broker as they know every lender’s criteria and will be able to match you to the lender most likely to accept your personal circumstances.

Can I remortgage my current home to help me purchase a Buy to Let?

If you don’t own a Buy to Let property but would like to, remortgaging your current home to release equity is one way you could do it. However, there are some factors to consider. For example:

  • Do you have enough equity in your home? Raising enough money to fund the purchase of a Buy to Let will depend on the amount of equity you have in your home.
  • Are you prepared for the costs and responsibilities involved in becoming a landlord? For example, all landlords are now responsible for checking their tenants have the right to rent in the UK. And you’ll need to check gas appliances once a year using a gas safe registered tradesman. For more on Buy to Let landlord responsibilities, read our guide Buy to Let Explained.
