There are now many mortgage lenders competing in the buy-to-let market. Since lenders profit margins are down within the 'normal' residential mortgage arena, more lenders than ever are now offering buy-to-let mortgages.
Broadly speaking you will need a deposit of at least 15% for a buy-to-let mortgage. A deposit of 25% or more will give you a lot more choice.
Buy-to-let investors should be aware that Buy-to-Let mortgages are not regulated by the Financial Services
Authority. Therefore, Home.co.uk recommends that all potential landlords
should contact an qualified independent mortgage advisor for the best
buy-to-let mortgage advice
