With a Buy to Let mortgage, the amount you can borrow is usually based on the rental potential of a property, not your salary. Providing you have a sufficient deposit, and you are able to obtain at least 10% over your monthly mortgage repayments in rent from the property, you should be in a good position to borrow.

NB In most cases lenders will ask for around 15% deposit of the value of the property, however this can vary.
