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?

Now syndications have become a team sport intended to mislead.

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

I could not find any details that confirm that 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. 

Then just yesterday, I come across the 1099 / 1099-NEC form requirements online from my own research.

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).

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

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

A specific property you find online would be even better.
