First-Time Buyer Buy to Let Mortgages

For many first-time buyers, the property ladder traditionally begins with a residential home. However, some people are choosing to enter the market as investors. A First-Time Buyer Buy to Let mortgage gives you the chance to purchase your very first property with the intention of letting it out, creating both a potential income stream and long-term financial security.
At Mercantile Trust, we specialise in supporting new landlords — even if you don’t yet own a property.
What is a First-Time Buyer Buy to Let Mortgage?
A First-Time Buyer Buy to Let mortgage is designed for individuals purchasing their first property specifically to rent it out. Unlike a standard residential mortgage, this type of loan is tailored for those looking to start a property investment journey rather than buy a home to live in.
Not all lenders accept applicants without property ownership history — but at Mercantile Trust, we take a different approach. We assess each case individually and look at the full story, not just your credit score or background.
