Given its age, we’re planning for a roof replacement and two new AC units within the next few years, which we estimate will cost around 15 - 20k in total.Our single family rental, built in 2020, is newer, so we don't expect major repairs anytime soon.On average, the duplex runs about $400–500 per month in maintenance and repairs (including significant repairs like AC replacements), whereas the SFR averages under $100 per month.

But according to Zillow, tenants stay on average 3-5 years in a rental.
