Clear Advice for Property Investors

Whether you’re buying your first rental property or growing an existing portfolio, buy to let mortgages work differently to residential lending. We help landlords understand the rules and secure finance that fits their plans.

At The Mortgage Heroes, we help you understand how buy to let lending works and guide you towards lenders whose criteria align with your investment goals.

What is a buy to let mortgage?

A buy to let mortgage is designed for properties that will be rented out rather than lived in by the owner. Lenders assess these mortgages differently, placing more emphasis on rental income, property type, and long-term sustainability.

Many people assume buy to let mortgages are simply residential mortgages with a different label. In reality, the criteria, affordability calculations, and tax considerations are distinct and can vary significantly between lenders.

Who can qualify?

Buy to let mortgage criteria varies by lender, but you may be eligible if the property is being purchased to rent out, the expected rental income meets lender requirements, and the property type is acceptable. Lenders will also consider your personal income and whether it meets minimum thresholds.

A suitable deposit is usually required and is often higher than for residential mortgages. Whether you’re a first-time landlord or an experienced investor, we’ll explain what’s realistic and where you stand.

FAQs

  • Do I need to already own a home to get a buy to let mortgage?

    Not always. While many lenders prefer applicants to already own a residential property, some will consider first-time buyers or first-time landlords. Criteria varies widely, so lender selection is key to avoiding unnecessary declines.
