I look at listings 3x a day.

And that’s pretty close to the response I have planned for anything that was obvious, in plain sight, or as minor as some of the things you listed.

Ironically its the investors in the layered LLC's who believe they are hidden in the cloaks of secrecy and better protected who end up in  the most costly and drawn out litigation while giving the plaintiff attorneys reason to take a more thorough look under the hood.Keep your LLC ownership simple, carry appropriate insurance, make sure ever vendor you work with carries appropriate insurance and those who perform work functions most likely to lead to liability exposure list you ad additional insured (not merely certificate holder) and it should go without saying, avoid negligent conduct.

All three had not been listed yet.  

There are many options for skip tracing, most just send a query to a single database while others hand-scrub the lists for the results.

To research the market, we look at other Furnished Finder listings in the area to help determine competitive rental rates.

You could offer listing service for them.
