where are you?
I’m in Utah, and we’re in the same situation (our house doubled since we bought, which was ~9 years ago). The numbers I cited are national though, so obviously it’ll lose a bit of nuance that’s more relevant to specific states, and numbers can vary wildly from city to city. Also, other expenses can vary wildly as well, such as auto insurance being much more expensive in Florida (from what I hear) vs Utah, despite both being no-fault states.
But even in my area, there are still affordable houses. Mine may have doubled, but houses just 15 miles or so away haven’t increased nearly as much.
