“Buy-to-Let" is a form of residential investment where you buy a property, usually with the aid of a mortgage, and rent it out. The 1988 Housing Act made investment in residential property more attractive to landlords when it introduced a new type of tenancy giving landlords more control over their properties and there has been a modest recovery in the private rented sector since then. The increased availability of loans at attractive rates of interest for Buy to Let purchasers, has also increased the appeal of owning rental property. 

The majority of buy to let loans are assessed on the expected rental of the subject property, although there are a few schemes that will base the loan on your income.  Loans are available up to 90% of the property value.
