I am 4 years older than you. My wife and I have lived in our current home for 38 years. So we don't move much, either.
We still love our current house, but the staircase is getting to be a bit much for my wife. So we will probably move in the next couple of years.
Hint: Those stair lifts can be installed for around $2000. Waaaaaaaaay cheaper than moving.
“...but the staircase is getting to be a bit much...”
I hear you. I’m making a move in a few years to single story that is ADA compliant. I don’t need the ADA compliance (yet) but it sure makes moving things around a whole lot easier (i.e. wider doorways and hallways).
