Nearly all of them.
At one point the bank offered to keep the house and they could pay the same rent as the mortgage they were paying to stay in it but they've stopped that now.
I'll be with the pair of them within the hour (my 65th today) so I'll ask what percentage sell up or try to pay it off.
Me and the wife had an interest only but we took an endowment out with it at the same time (a type of insurance).
We were told in 1983 that the endowment would pay £30,000, £14,000 for the house and £16,000 in our pockets.
We were very lucky compared to some, at the end of the 20 years we owed £1200 because the endowment didn't pay out what we were promised.
One of my very close friends has only paid the interest but has lived in hope that the day their Mum dies they get the money to pay off the mortgage.
If the Mum doesn't die in the next 3 years they are buggered.
