I'd ask for a copy of their lease agreement for good measure.

If they are a REALTOR you might can get them sanctioned for Ethics violations.Another last step is contacting the state real estate commission and filing a formal complaint.

Among those remedies are both civil and criminal sanctions that may exist in your particular jurisdiction.

BTW we always put up craisgslist test ads to measure demand at a price higher than the subject parks rents.  

Crying over taxes taken by the government and taking some measurements and video of a flip to send out to contractors for ball park estimates.

Then approach that person and ask them if they would be willing to mentor you for a specific length of time, for a set fee, with measurable results ( the best result is doing a profitable deal in the new manner you wanted to learn).I would shy away from individuals who are affiliated with TV Realty stars or self-styled Real Estate "gurus." 

It is great to be in a store and have a list of items needed, pictures, and measurements on a device I never go anywhere without.

They came out and measured then ordered a new low-e dual pane panel and l ater came out to the house and replaced it in like 15-20 minutes.

The only sign of the  long term weakness is the measure of,  "can the average worker afford the average house?"  

., would I just take the last 15 bookings for each of the 2 units as a time measurement, and then average out how well they did?
