Before we moved into our current home 3 years ago, we (total of 8, with 6 children) lived in a 1300 square foot house with 3-4ish bedrooms and 2 bathrooms. 1 bedroom and 1 bath was in the basement, so the kids didn't like using it, so it may as well have been a 3-bed 1-bath house (not easy for 8 people). And the bathrooms were tiny, the size of a largish closet ... which of course women and girls can't abide. We did however have about 700 square feet of finished space in part of the basement that served well as a family room. I got that for $125K. I actually loved that place. Had 2 acres, and it was a beautiful large wooded lot. Was on a big road, however, and no sidewalks. So it wasn't my wife's cup of tea. I on the other hand really enjoy nature. I think the kids really miss the place. Plus it had a wood-burning fireplace, a well, sceptic, no need for a sump pump in the basement, etc. I regret leaving that place behind.
It was built in the 1940s. One thing I notice. They used REAL lumber to build it. I've never had as much difficulty driving nails into the studs and joists that I did in that house. That was some incredibly solid and hard wood.
Thankfully, though, when we bought this house a couple years ago, we got a really good interest rate and were able to later refi at 2%. We'll never see those interest rates or those housing prices again.
