Looking at it, tenants pay only electric so you'd be paying water,sewer, garbage, landscape and maintenance.

as far as how much electric , its all relative to how much water being used .

Also, the supended ceiling in the basement clearly is wrecked from water damage, although during inspection no source could be found and above the ceiling everything looks good. 

Two of the homes are on one lot, and the water is NOT metered seperately.

If market rent is $1000, and you are renting for $750, you are leaving a lot of money on the table. 

My interpretation would be that if you can't move in within 60 days because rehab took longer than expected, so be it, but that wouldn't waive the 12 months of occupancy thereafter promise that you will make at the closing table. 

Obviously it is a benefit to pay for water because perhaps the tenants could water the landscape. 

Unfortunately I live in southern Alabama, so basements aren’t common here because of the water table.
