@Yosef Ajami, we use Quickbooks Online for all of our Clients (including syndicators).

I wanted a cohesive, fairly upscale look, so bought new from a variety of places including a local furniture store, Amazon, Wayfair, Target online, Home Depot online, Pottery Barn, Article, and others.

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.

I could not find any details that confirm that online.

They sell you on the platform before you can actually get in and play around.  

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

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.
