No, I wouldn't. Different to a natural death in old age. Couldn't buy a house where someone had died violently or had been so desperately unhappy it had driven them to kill themselves.
It may not be rational. But I couldn't do it.
We bought this house because it was the one ds (then four months old) was happiest in when we were looking round! (It was a rational choice in terms of price and location, too.)
I once went househunting with a family friend. She was looking at a lovely big Victorian house, loads of character. Opened a cupboard in one of the attic bedrooms and the atmosphere was just horrible. I'm not kidding when I say the temperature in the room dropped (and no, there wasn't a draft or a big hole in the wall or anything). It was really dramatic and awful. She didn't buy it. Couldn't stand whatever was up with that room and certainly couldn't put one of her children to sleep there.
