How do buy to let mortgages work?

A Buy to Let mortgage is a loan secured against a property which you own and intend to rent out. The main difference to a residential mortgage is that with a buy to let mortgage the amount you can borrow is based primarily on how much rent the property can earn, rather than your own income – our calculator can give you an idea of what you could borrow. When you have a tenant paying rent, the rental income should cover the cost of the mortgage, ideally with some left over, but that's not guaranteed. As with a normal residential mortgage, it's your responsibility to meet the mortgage repayments each month even if the property is not let out.

Becoming a landlord is not for everyone, and there are multiple things to consider before getting a buy to let mortgage.

Here are some questions worth considering for each potential area you're thinking of buying in:

  • Does the area have good transport links? Are there any plans to improve these?  
  • What about schools, shops and local amenities (cinemas, restaurants, parks etc.)?  
  • Is the area 'in demand' right now? Is that demand expected to grow long term?  
  • What type of tenants are living in this area today (married couples, students, families on housing allowance etc.)?  
  • Is that demographic expected to change any time soon?  
  • What type of properties do tenants in this area desire most?  
  • Is there a benchmark level of rent I can expect to receive here?  
  • Are the majority of letting properties in this area furnished by the landlords?  
  • Is there a certain property type which is expected to grow in this area, potentially even to a point of oversupply?  
  • Are there any major developments due to begin here within the next 10 years?
