Expect to need a minimum deposit of 25 percent, and quite possibly more for a first-time buyer BTL application. Some lenders who will accept first-time buyers on a buy-to-let basis require 30 to 40 percent. This reflects the additional risk they perceive in lending to a borrower with no prior experience of property ownership.
Because you are a first-time buyer, you do not lose your first-time buyer stamp duty relief on your eventual primary home purchase. However, you do pay the 3 percent SDLT surcharge on the buy-to-let property you are buying now.
The rental coverage test is the same as for any buy-to-let: the expected monthly rent must cover a set multiple of the interest payment. For first-time buyer applications, some lenders apply a higher coverage threshold such as 145 percent at a stressed rate. A property generating 1,200 pounds per month might comfortably pass the rental test for an established landlord but come up short at the higher threshold applied to a first-time buyer.
