Let to Buy
Helping your clients move home while keeping their current property.
Let to Buy is a solution for clients who want to retain their existing home and rent it out, while purchasing a new residential property. Whether your client is relocating for work, upsizing, downsizing, or simply not ready to sell, Let to Buy offers a flexible way to transition between homes.
What is Let to Buy?
Let to Buy allows clients to convert their current residential property into a Buy to Let, using the rental income to support the mortgage, while simultaneously securing a new mortgage for their onward residential purchase.
Key features:
- Available for both standalone Let to Buy applications and where we’re also providing the mortgage for the onward residential purchase
- Up to 75% Loan to Value (LTV)
- Maximum individual loan of £750,000
- Maximum portfolio size of 3 mortgaged Buy to Let properties per applicant across all lenders, including Bank of Ireland Group.
- Property must have a valid Energy Performance Certificate (EPC) rated A-E (or A-D in Scotland).
Affordability assessment:
- Assessed using Interest Cover Ratio (ICR) or Top Slicing, depending on the client’s income and rental yield
- Rental income must be in GBP and meet minimum coverage requirements.
Best for clients who:
- Are moving home but want to retain their current property as an investment
- Need to complete both transactions simultaneously
- Have sufficient equity in their existing home to support a Let to Buy mortgage.
