I am surprised they are running out of hot water fast, the smaller tanks should heat the water faster than the larger 50 gallon tanks, maybe look into small tank heaters with more heating coils to heat the water even faster. take a look at this one, available from HD too https://www.rheem.com/product/marathon-30-gallon-e...that one may deliver enough hot water for your tenants.

You will always have a mortgage payment eventually, pay interest, insurance, water/sewer, save for your reserves such as vacancies, cap ex, and repairs, and of course, can't forget property management if you are not planning to manage them yourself.
