Let to Buy mortgages are a structured financial arrangement designed for homeowners who wish to retain their current property while purchasing a new residence. This type of borrowing involves converting an existing residential mortgage into a rental-based loan, while simultaneously taking out a new mortgage for a primary home. The approach is commonly used where relocation, upgrading, or lifestyle changes are required without immediately selling the original property

It is a dual-loan arrangement where the borrower keeps their existing home and rents it out, using anticipated rental income to support affordability. At the same time, a new residential mortgage is obtained for the property that will become the borrower’s main residence. Lenders assess both transactions together, and approval is subject to underwriting standards, risk assessment, and regulatory compliance. How does Let to Buy work? Typically, the borrower applies to refinance their current home onto a rental basis. The lender will evaluate the expected rental yield and may require a minimum rental coverage ratio. Concurrently, a separate mortgage application is made for the onward purchase. Both loans are interconnected in the assessment stage, and completion often occurs simultaneously. Legal, valuation, and affordability checks apply to each property independently, even though they form part of a single strategy. Who is a Let to Buy mortgage suitable for? This arrangement may be appropriate for individuals with sufficient equity in their existing property, stable income, and a clear intention to become a landlord. It is generally considered by borrowers relocating for work, upsizing, or retaining a property for long-term investment. It may not be suitable for applicants with limited equity, unstable income, or insufficient rental demand in the property’s location. Let to Buy vs Buy to Let: what’s the difference? While both involve rental properties, a Buy to Let mortgage is used specifically to acquire an investment property, often without prior ownership. In contrast, Let to Buy applies to an already owned residential property being converted into a rental asset. The borrower in a Let to Buy scenario also takes on a new residential mortgage, making the structure more complex and subject to additional scrutiny.
