Often these properties are unlivable without working heat or water.

If a Property Management company is managing enough properties it's only a matter of time before one insurance bill falls through the cracks and boom of course Murphy's Law will kick in and that'll be the one that has a no heat in the winter or something of that nature causing uninsured damage.Going forward I'd vet your PM's more carefully to see that they are more established.

Anyone find one of these ? 
Trulia USED TO have a great one but took it down for some reason (I got confirmation from their support team).  Neighborhood Scout is another one but not very detailed if you zoom in / out...

Keep in mind if you fill hole with concrete in warm weather the sun will heat the concrete and make the grass above it brown. 

If so, crank the thermost up really high, and see if it finally heats up.

Recommend cleaning and / or generalservicing of the heating unit by a licensed / qualified heatingcontractor prior to close.Heating - Air 16 Tenants complained about not having heat on the 3rd floor.

The property is old (1913) but I updated it mostly (plumbing, HVAC including heat and ac, new ducts new roof, plumbing fixed flooring redone.)

I don't have anyone in mind for you as I don't invest in Ohio, but if you're iffy about your agent now wait until the heat goes out in Jan and you need to get it fixed asap and your agent/ PM is nowhere to be found. 

Ivy City, Union Market, H Street development, and Bladensburg Road development is heating up.

(Just replaced the heating boiler in one of the houses and that was an $8500 expense). at your $200/month expected maintenance bucket, you would need almost 4 years of savings to be able to cover a similar expense.
