Taking that a step further, I've been interested recently in the feasibility of moving entire structures/homes to new locations. There's plenty of houses in rural America that are withering away. If there was a way to economically move homes to land in urban areas, it could help to solve the problem. I'm assuming the unit economics and feasibility simply don't work out, or else my million dollar idea would've been taken already.

Older houses in urban areas are typically seen as a negative rather than a positive. If you could sell the land without a house at all, you could save on demolition costs when the buyers of that high value property knock down the old house and build the house they really want.

Houses really do depreciate with age, even if it is less noticeable in the USA than it is in say Japan.

Good luck building a new home to replace many older urban homes in US cities with the same quality of building materials and workmanship. Also, it is typically much cheaper, easier, and quicker to utilize existing structures by expanding or modifying the layout, especially given the high costs and lack of availability of building materials.
