Your question about hydrostatic pressure is getting into the weeds for sure...I would ask myself, does the potential water infiltration have the possibility to damage the unit and tenant property?  

We have had many water leaks that have damaged the flooring.

Both Ecobee and Honeywell are great options for smart thermostats so you can remotely control the temperature settings and set temperature ranges. 

Hi MichaelFor a seller-financed deal, especially for a multifamily property like a six-unit or larger, a typical down payment could range from 10% to 20%, depending on the terms you negotiate with the seller.

@Sharma Parth the company is out of Arizona and in 12 markets.Just a few years ago, Flint had a major crisis due to lead water line poisonings.

They take the path of least resistance and always seem to blame their PMC for everything that goes wrong.Recommend you take some time to understand what the above graph represents and why your PMC is probably not the problem.Regarding your two PMC idea - how many water meters are there?

:)As for LTR rental terms, usually we sign a 1 year lease where tenants are expected to pay Electric and Gas if applicable, while the owner typically pays water/sewer/trash with the city. 

In Ohio you can find a lot of single family in the $100-200k range or 2-4 units in the $150-400k range that do pretty well cash flow.

@Shafi Noss Improving the land would be the simplest since there's already a driveway, electricity, and an old water well that needs to be jetted again.

I’m in a similar situation but plan to meter water and power with my own units that can be read.
