The amount of equity that you can release from doing a buy to let remortgage will depend on your current loan to value ratio, i.e., how much of the property do you own already.
A buy to let remortgage for capital raising is different from a residential mortgage as you can only borrow a maximum of 75% to 80% of the property value compared with 90% or even 95%.
We find that many of our landlords choose to release equity for 3 main reasons, one to buy another investment property, two to repay debts and three to pay for property improvements.
