This seems to be breaking down new construction and is a national average so kind of hard to read into this what it means in general but I would not expect a 665k new construction house to be my target for a rental property. 

Personally, I would not keep a rental that is not expected to cash flow. 

Yes, distributions have been below expectations and way below NOI projections. 

They've been very underhanded and petty though, I do expect a court filing if we simply ignore.

The rental market has slowed in recent months but expected in winter.

I expect that means it needs to be 15 years or more.

It is something I am interested in doing in the future, potentially even this year, but I am curious how to put concrete numbers to this decision.  

I would say to expect a floor rate of 6-6.50%

Tenants should pay  utilities - they're consuming those and landlords should 'inspect' what they expect on a quarterly basis and that includes verifying that utilities are current.
