The lesson I learned, is that the longer you are in a house, the more obsolete it is, buyers are looking for certain things, and if the house isn’t “modern” they won’t want it, and it seems the things people want in a house change every couple years.
So if you don’t intend on constantly upgrading the house, best just to move every five years or so, so the house isn’t “out of date”, or requires you to spend tens of thousands of dollars just to get it to sell.
Someone should have given us that advice when we moved into our house in 1976 and it was already 70 years old :)
