I haven't seen this one circulating online in a while but the advert stated that those who attend are provided a list of 300 CRE brokers.

Plenty of information online about them so I wont go into too much detail as information is easily available - but that would be another great option for both parties. 

Searching online, it seems all the property managers have awful reviews. 

Their online rent collection also deposits directly into these accounts, which is super convenient.It really simplifies the financial side of things.

If you;re after the 'knowledge', you really don't learn that much by becoming an agent, you can study online and gain that info anyway, and a lot cheaper.

I understand I can use the different EINs to setup accounts for each child LLC but looking more for recommendations on whether there are banks in and around Washington state (or online banks in other states) that allow having Primary-Cell type accounts where all accounts are housed under one roof but with the ability to have different EINs.

If she left the utilities on and her possessions were still present inside, you'd have a hard time making the case to a judge that she absconded.One "short cut" you could try is reaching out to her and explaining your situation with her still in legal possession of the unit and not paying rent to ask her to send you a "return of possession" notice (search it up online) to stop the accruing charges to her. 

Most of the big stuff never gets listed online.

That's why they are agressively promoted online and through social media. 

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