The portfolio landlord, the first-time landlord or even the accidental landlord… wherever you are in your investment property journey, we are here to help.

Securing a buy-to-let (BTL) mortgage may not seem that different to the mortgage taken out on your home. However, differences in the way they are calculated, their varied criteria and the risks involved in getting it wrong can make finding the right product a slow and lengthy process.

Enlist the help of a mortgage consultant from Crystal Private Finance, and we’ll steer you through the best channels of this potentially lucrative market.

What is Buy-to-Let?

A buy-to-let mortgage is the type of funding used on a rental property.

The laws surrounding affordability calculations has been subject to change as of late, and some lenders can implement these changes more rigidly than others, which is why now it is crucial to enlist the help of our experienced mortgage consultants.

BTL lending is not regulated by the FCA unless a close family member will be letting the property.

Common Uses

The use of BTL finance can seem self-explanatory. However, this adaptable set of products can do more than your average mortgage:

This branch of BTL is assessed with the same rigid criteria as a residential mortgage, as “landlords of circumstance” are viewed as consumers and need to be protected as such.

A let-to-buy allows you to purchase a new property while renting out your previous residence. The amount a lender is willing to lend is calculated by rental coverage and does not take your existing mortgage into consideration.

The are many positives to refinancing. Whether you are looking to raise funds for a light refurbishment or purchase a new property, the equity stored in a rental property can prove useful. Refinancing could also prove lucrative with those looking to save, enabling landlords to transfer to a lower rate product.

Whether the transaction is straightforward or a more unusual arrangement, our highly talented team will be able to assist you.
