How Can I Switch to a Buy to Let Mortgage?

Switching from a residential to a buy to let mortgage can be a daunting process, especially if you’re unsure if you’ll pay any early repayment charges or mortgage set-up fees.

But if it can unlock the rental potential of your current residential property and help fund your ambitions to move or go travelling, it’s well worth the costs.

There are a few different ways to switch to a buy to let mortgage from a residential one and some key points. This guide will cover everything you need to know about the process and how to go about it.

Switch to a Buy to Let Mortgage

When is a good time to switch to a buy to let mortgage?

If you’re thinking of switching from a residential mortgage to a buy to let mortgage, you’re probably in one of the following situations:

  • You’re moving into a new property with a partner and retaining your own
  • You’re moving to a new city for work and won’t be using your home for several months
  • You’re going travelling and won’t be living in the property for some time
  • You’re buying a new home to live in but want to retain your current property for a rental income source
  • You’re moving abroad but want to maintain a UK base and rent it out 

What are my options for switching to a buy to let mortgage?

There are two main options you have when it comes to swapping to a buy to let mortgage:

  • Getting ‘consent to let’ from your current residential mortgage provider.
  • Remortgaging to a new buy to let mortgage product with either your existing provider or a new lender.

We will go over the differences in more detail next, but generally, a consent to let agreement is more relevant for shorter-term let arrangements than long-term buy-to-let plans.

Can I just rent out my home without telling my mortgage provider?

In short, no.

There are different regulations for residential mortgages and buy to lets.

This means that if you let out your home without your mortgage provider's knowledge, you could be breaching the terms and conditions of your loan.

If you speak to your current provider about renting out your home, they might let you do it without requiring you to remortgage.

Swap to a Buy to Let Mortgage

Could I get consent from my current mortgage provider to rent out my home?

Yes, depending on your exact plans.

Getting consent from your current mortgage provider to let out your home can be the simplest and most cost-effective way of getting the right to rent out a property you own.

You’ll need to have a conversation with your current lender about what you’re planning to do and for how long:

  • Usually, the maximum duration you can let out your home for is between 12 and 24 months to qualify for consent to let
  • You could be rejected if your projected rental income is too low to cover your mortgage and other monthly outgoings.
  • And you could be rejected if your mortgage lender suspects that your original intention was to rent out your property when you secured your residential mortgage to secure lower rates.

Can I swap my residential mortgage for a buy to let mortgage?

If you cannot convert your existing mortgage, then remortgaging onto a buy to let product instead may be your only option.

You can remortgage with your current mortgage provider or entirely go with a new lender. You may get a loyalty discount from using the same mortgage provider, but make sure you check what’s available to compare to the rest of the market.

If in doubt, speak to a mortgage broker. We have saved our clients thousands of pounds on interest payments simply by switching to a new lender for a remortgage instead of accepting their current provider’s mortgage rates.

Example Case of Switching Mortgage Lenders

You’ll need to pass your lender’s buy to let affordability criteria to ensure that you can keep up with your mortgage payments:

To qualify for a buy to let mortgage, your projected rental income will need to cover approximately 145% of the monthly interest repayments from your mortgage.

You are also likely to need at least a 25% deposit for a rental deposit - more than you’ll typically need to put down for a residential mortgage.

Remortgaging could also be an excellent opportunity to release some equity from your main home to put towards a new property or another asset.

How many buy to let mortgage products are out there?

Moneyfacts recently reported that there are now approximately 2,200 buy to let mortgage products on the market compared to just 1,311 in February last year, marking a 65% increase. It's undoubtedly a prosperous area of the mortgage market at the moment.

What are the costs of remortgaging to a buy to let?

It can be challenging to gauge the full range of costs you’ll incur by remortgaging your property to a buy to let, simply because there are some charges you might not expect to pay.

Here’s a list of all the costs you might need to pay when switching to a buy to let mortgage:

  • Early Repayment Charges (ERCs) on your existing mortgage

If you’re currently on a fixed-rate mortgage deal, switching to a BTL mortgage before the end of your fixed term of interest could cost you roughly between 1-5% of your outstanding loan amount in ERCs.

  • Set up costs for a new buy to let mortgage

These could range from £500 to £1,999 depending on the lender you go with, the interest rate you pay, and the complexity of your case.

And don’t forget about:

  • Legal fees and valuation fees
  • Property maintenance and agents’ fees
  • Income tax on your rental profits

You may also need to consider whether you want to take out a fixed rate or tracker mortgage product. We have a guide on deciding: Should You Get a Tracker or Fixed Rate Mortgage in 2022?

Can I let out my UK property if I am moving abroad?

Yes, you can.

However, you will likely need to remortgage completely if you intend to move abroad, and you may have a smaller pool of lenders to choose from.

And you’ll need to pay UK income tax under the Non-Resident Landlords (NRL) Scheme for the rent you earn from your UK buy to let property.

We recommend speaking to a mortgage adviser if you are becoming an expat and renting out your UK home in the near future on a buy to let mortgage.
