If someone's looking to start LLCs layered under different entities it ain't me lolI would add expecting "push the Zillow button and expect $400 cash flow buying in 2023-2024 marketing using Other People's Money" because some social media guru told them RE investing is so easy after the run up in property values 2013-2022 and the guru quit their W2 jobs before the age of 40.

But everyone basically signed those agreements late into the search right before an offer was made, and because the seller almost always paid, it wasn’t the traditional negotiation you’d have upfront with a seller, 2ndly while I do think this is a net win for the consumer, the idea that the doj “solved a problem that didn’t exist” 1st of all it wasn’t doj it was a jury in Missouri 2ndly the issue is regardless of impact on consumer’s they were almost certainly violating anti-trust law which is illegal lol, the publishing of commissions and the fact that something like 98% of all agents were paid between 2.5-3% was textbook, imagine if the price for a ritz and a motel 6 we’re basically the same, you’d think collusion right? 

She has a co-signer willing to sign, but I'm hesitant with her age/safety (the garden unit has a steep staircase) and with rent being $1800 is that doable for her?
