What is the lifespan of the average home?

I live in a 1 1/2 storey home built in 1922. I have totally updated the home, (wiring, plumbing etc.). There has been some settling mainly on the second floor, not enough to prevent doors from closing. I purchased the home in 1999. I have not noticed any new settling since. I am wondering how long a lifespan a home built in 1922 has. I like my home but it is 84 years old. I will be entering retirement when this house turns 100. I maintain this home accordingly but I wonder if it is wise to have a 100 year old retirement home. I would appreciate some comments on my delima. Thank you.

As long as you have updated everything that needs to be, you should be safe.

I have installed new furnaces in homes that are well over 100 years old, and house looked great after they updated everything.

Working in many different aged homes, I've noticed back in the day they built houses to stand forever, now days they put the houses up as fast as they can and move on to the next one.

My house is over 100 yrs old now. Shouldn't be a problem if it has been updated.

Ideally, you could sell it and buy a motorhome at retirement.

When you can't operate that anymore, a retirement apt.

I think it can be old as you want it be. Meaning if you take care of it . It could last another 100 years.
