Sounds like more work to me! Plus you will have to worry about heat, air conditioning, plumbing, electricity, all the machinery associated with those things, probably some lot upkeep, maintenance of the home exterior, ah, the roof, the windows!
Right now, in my apartment, i dont worry about anything. Ever. I just dont have the temperament. I worried about EVERYTHING CONSTANTLY when i was in my parents house and for many years beyond. I just dont have any more energy.
I am probably a little older than you (69 is near!), but i jusr want to spend my time doing fun stuff, not chorey stuff! There are plenty of chores as it is!
