Even though I myself have a S8 rental, what you hear online is completely false.

What are the chances that someone would search this online forum, find this thread, and create an account just to make a positive comment on this thread about this company?

Find ways to consistently and systematically add more people to your database each week - i.e. cold calling, networking, online marketing4.

You can also check their reviews online at Google, Facebook, or Yelp.

I could not find any details that confirm that online. 

Each town is a little different, some require you to do a landlord registration and/or will want to do an inspection before you put a tenant in (calling the town would probably be the easiest, or they may have the info right online).

You'll need good contact info for them to be able to collect, and ideally the new address for the tenant however which if you don't have can probably be found easily with some online sleuthing/ contacting their employer, skip tracing software, etc. 

Sometimes these types of deals require that you purchase a software to help search for lots,so we'll see.Most of the time,established people in industry are not going to come online and scam people,why would they ruin their own business in the offline arena?

A friend advised me to check reviews online and look for someone local with experience in single-family homes.
