Buy to let mortgages fall into two categories which are consumer buy-to-let and investor buy-to-let mortgages.
Consumer buy-to-let mortgages are for those individuals who become accidental landlords who do not intend to run the property as a business. Accidental landlords arise when there is a change in circumstances. A typical example would be a single person owning their own home living by themselves. At some stage they may decide to buy a new home with their partner. As a result of a change in their circumstances, as a short term solution, they may decide to rent their former home to save themselves from paying two mortgages. A consumer buy-to-let mortgage is designed specifically for this type of instance.
