Move to a rural place where everyone is moving out and you'll find a place that is not densifying over time, but the opposite. And buying land & housing there is incredibly cheap, probably less than the cost it would be to build it! This is pretty much happening in every small-ish town in japan for example.

Your social life and neighbors will more skew towards the grey haired spectrum, but that is the sacrifice you will need to make!
