Same here. This seems lost on many.
Instead of a huge chunk of money being handed over to the builder in the cost of a house, I handed thousands to the mortgage lender at upto 15% interest rates. The proportion of my monthly pay that went on the mortgage and basic bills such as gas/electric/water/poll tax was massive. As I said, I had to think carefully before buying a hifi magazine.
Some will never understand, they don’t want to.
Gas fitters for BG must have been amongst the most highly paid people in the land then and pay hasn't kept up with inflation. Either that or he was just better with money than most.
