Got married in 1976 and we bought a 1900s semi to do up, it was all we could afford at £7,900. The house didn't have central heating but had 2 coal fires. The walls were of wood and the house was full of woodworm. The mistake agent said that we would be able to do it up. Being young in our early twenties we believed him!
The first thing I did was to buy a saw and cut out the wooden walls, they were like aero, full of holes. The next thing was to get Rentokil in to treat the remaining wood. We were never bothered by flies for years, a bit strange as we lived next to 2 farms.
We struggled for several years before we managed to put the house right. As my wife says if we could have been given a bigger mortgage we could have bought a 2 bedroom masionnet and saved money whereas we ploughed money and effort in with little return.
I think we sold it in 1985 and bought a new house.
