Exactly Uncle ~ Remortgage to pay off your debts and existing mortgage ~ and when house prices and interest rates rise again, as they surely will, leaving most who have fallen for their scheme unable to pay the new mortgage, the b@st@rds will repossess the house and sell it at a handsome profit. Given the decline in construction they know that the shortage of housing can only get worse and that in five years or so they will own a nice fat portfolio of properties to sell on.
My advice ~ hang on to what you have, make do for now, go without if necessary but whatever you do, borrow nothing.
