Our mortgage was/is 75k, house cost us 79k, its a full repayment mortgage, 2 bedroom mid terrace, 3 floors. Lovely area.
I think the house is worth 100-120k (at the current overinflated prices). My mum and dad bought their current house, a 5 bedroom detached converted bungalow with a huge garden in one of the best areas in Bradford for 93k 8 years ago. Its now worth more than a quarter of a mil. Scary world isn't it.
A crash is overdue but what good it will do I don't know, there would be a lot of people in trouble who had just bought houses.
