Horror story #2: while selling off one of the Class C Indianapolis properties, buyer asked me to pay replace the sewer line before closing... absolutely not...here's a partial credit (check to written out to contractor from closing proceeds so buyers don't pocket the money) 

Conceptually you want to take an approach that minimizes your need to be on site - and for that reason I would advise against BRRRR.

I see no value in it for evaluation.Realestate.com has always been a good site for accessing properties, but they do a poor job of evaluation. 

Our site is RIDICULOUSLY sensitive to spam.

Which sites do you recommend for pricing? 

If you have a 10% interest rate on a car loan, then paying that off would give you a risk free 10% rate of return.  

Insurance is paying for the stay.

After paying a competitive rate for the property management and ASSET management that the small operator does himself.  

I am aware of Crexi, Bizbuysell, and Loopnet and reach out when I see something for sale on those sites.

Some sites are not able to provide back a credit score, because they don't know how you will handle the data.
