Last time I was looking to buy a house I was struck by how “the same” everything in my price bracket was.
By that I mean nearly everything was 3000+ sq ft, but was always 3 bed 2 bath. Maybe you got a bonus room or “play” room. But not a lot of really cool or useful extras for the increased cost.
So outside of just those rooms being larger, there was not much difference in the $150k house and the $300k house. They all had the same number of bedrooms and bathrooms, a garage, a decent kitchen, dining room, and “bonus” room of some description. I also noticed that the $300k houses also tended to be in a quarter acre of land while the $150k houses tended to be a half acre.
Did not really feel like you were getting more for doubling the price to me. Once you got enough square footage to meet your basic needs it was all diminishing returns.
