To be fair, my father had rentals when it was much harder to do background / credit checks. It might be easier to screen prospective tenants now.
He has long since sold his rentals.
But better tenants still won’t eliminate the midnight “the water heater just went” phone calls…unless you go with a prop mgt company. Then you have a whole new set of problems of the fox watching the henhouse sort…
Buying rentals is tempting, granted. I still re-evaluate it in my mind from time to time. But then I realize how successful I’ve been at keeping my life simple and streamlined and chuck the idea altogether.
