The house I grew up in was built in 1865.
My mom moved to a different house built in 1857 and I spent a year there after college and visited there for 25 years before she moved to TV.
The house my wife and I have lived in the past 25 years was built in 1949 although we did 2 additions to this one.
The first TV house we bought was built in 1992, the second 1998. Two built after I was born, I must be moving up
.
Every house has quirks and issues and you make it your own. Pretty soon that new house is 3 years old, are you going to turn the lease in for a new one?
I'd much rather move into a shed and enjoy my retirement than to wait a year just because it's new. New is nice I suppose, but it's just things. Things come and go, get older and break.
