Let to Buy

Let to Buy is a handy option if you’re ready to move home but don’t want to sell your current property. Instead of selling, you let out your existing home and use the rental income to help fund the mortgage on your new one.

It’s especially useful if:

  • You want to keep your current property as an investment

  • You’re struggling to sell but still want to move

  • You want to keep a foothold on the property ladder

With Let to Buy, you apply for a Let to Buy mortgage on your existing home — this is a special type of buy-to-let mortgage that acknowledges you’re letting out the home you used to live in. At the same time, you arrange a residential mortgage for your new home. Both mortgages run alongside each other, and the rent from your old home helps cover the Let to Buy mortgage payments.

How does Let to Buy work?

Here’s a step-by-step example:

  1. You find a new home you want to move to.

  2. Instead of selling your current home, you rent it out to tenants.

  3. You switch your current residential mortgage to a Let to Buy mortgage.

  4. You use any equity in your old home (and possibly rental income too) towards the deposit on your new home.

  5. You take out a new residential mortgage on the new property.

You now have two properties: one you live in, and one you rent out — and two mortgages to go with them.

What are the benefits of Let to Buy?

✅ Hold onto your property
You stay on the property ladder with a second home that could grow in value and generate income.

✅ Avoid selling in a slow market
If it's not a good time to sell, Let to Buy lets you move without waiting for a buyer.

✅ Flexible future options
You can sell the original property later, keep it as a long-term investment, or use it as a stepping stone for further property ventures.

What should you consider?

Let to Buy can be a smart move — but it’s not for everyone. Here are a few things to keep in mind:

  • Affordability: You’ll need to show you can afford both mortgages, even if rental income helps.

  • Deposit size: Most lenders require at least a 25% deposit for the Let to Buy mortgage.

  • Rental potential: Your lender will assess how much rent the property could achieve, and whether that supports the mortgage.

  • Tax implications: You may have to pay additional Stamp Duty and be liable for Capital Gains Tax when selling your old home later.

  • Landlord responsibilities: You’ll become a landlord, which comes with legal and maintenance obligations.
