@Donald @Donald Hathaway...We are an authorized HUD Brokerage and can talk you through the "process" of how to win.We also provide links to comps, CMA's, etc. to help you ascertain value.Let me know if we can help you be successful.

You simply must ascertain if the guest is permanent or not.

In order for me to ascertain the property I must first ADD my name to the DEED.

Would you recommend using home advisor's estimate costs tailored to the specific zip code I'm working in to ascertain costs?

After conducting the above due diligence, I would do market research and ascertain what kind of venues are in demand there.

Then do regular inspections to ascertain they have not done so.

I'd look at any property under appraisal techniques first, but figure yours both ways and get comps and try to ascertain marekt value.

You might want to have your plumber do a use analysis to ascertain the correct system. 

I searched Air B&B and VRBO but only came always with a date specific rate that seems to be highly dependent on demand (difficult to ascertain annual average) and no info on vacancy, what am I missing?  

I care far more about length and type of employment, as certain jobs and time on the job may show the person is able to conduct themselves in a manner that makes conflict with me less likely.
