And yes, have a list of plumbers, electricians, etc, so that if something happens you can get it fixed in a timely fashion. Stuff always seems to happen at the worst time. I had a tenant’s sink back up while they were cooking thanksgiving dinner for family.
My advise would be to charge on the high side, be very picky about choosing tenants, and never raise the rent on a good tenant. You do not make money on turnover.
