Understanding buy to let mortgages

If invest in residential property to let to paying tenants, you cannot use an ordinary mortgage. A specialist buy to let mortgage is required. 

Demand for buy to let finance has soared since it first took off in 1996. By the end of 2014, around 15% of all outstanding mortgages in the UK were buy to let loans. Competition has led to a booming market, with diverse products available to suit all kinds of property investors.

As a specialist buy to let mortgage broker, our goal is to find you a great deal on a product tailored to your requirements. Your advisor will undertake a comprehensive search of products from a wide range of lenders.

Buy to let mortgages are based on the rent, rather than personal income

Buy-to-let mortgages are specialist products that allow you to borrow based on the rental income-generating potential of your property.

Therefore, even if you have a low personal income, we may be able to help you. As long as your rental income sufficiently covers your mortgage interest payments, there are lenders who will consider funding your venture.

Lenders use rental income to calculate how much you can borrow. Lower rent limits how much you can borrow against a rental property. But different lenders use different rental calculations. We understand where your application will have the best chance of acceptance.

The minimum buy to let deposit is 15% of the property value

Buy to let investors must put down larger cash deposits than owner-occupiers. The most any lender will agree to lend is 85%, leaving the borrower to cover the remaining 15%. (This is an 85% loan to value, or LTV, mortgage.)

Compare low-deposit mortgages

Not all lenders allow borrowing up to 85% LTV. Most lend no more than 70–75% of the property value. And if you want to qualify for products with the lowest interest rates, you will need to borrow no more than 60%.

60% LTV mortgages are more suitable for risk-averse investors who prefer a larger equity buffer. Between the lower interest rate and smaller loan size, they also allow investors to keep their repayment costs down. And if your eventual goal is to have an unencumbered property, 40% of equity gives you a good start.
