I found a LOT of success with a site called Furnished Finder as well. 

Welcome to the site and best of luck on the journey! 

Lurid story, but boils down to a basic eviction for cause as you've laid out.You can send an email to the domain owner for that Czech site, but I would probably leave it at that.

Did a lot of people leave this site?

Their income reports are great.Really easy to export constant changes to Airbnb, VRBO, direct site.

For example, if your place rents for $3500 (and lets assume 6% vacancy) Nomad charges 4% with a flat $1250 listing fee to take professional pictures and list it on 20 different sites for you that would cost $2697.60 for the year. 

This is what I and many many others on this site did when we started. 25 is a great age to work very hard and see benefits in a very short time compared to a 35 year old with kids who has to outsource everything shooting for a 8-12% returns due to life obligations.

According to the IRS guidelines, mobile homes set on concrete blocks and that are always capable of being moved from their sites on their own wheels are considered personal property (5 year).  

Also, if I do, is there certain information that I should be gathering/evaluating, and certain questions that I should ask of the people working at the site to make the most of the visit?

I am not familiar with the site.
