We're in Ithaca now but I'd be happy to connect with you. 

Plenty of people are happy they took those kinds of risks.

I'd talk to brokers in your specific asset class and market.Do you already own similar assets?

I'd venture to say that an experienced attorney propbably wouldn't charge much, if anything at all, to set up your LLC if you are working with them on an operating agreement. 

I'd say the amount of time for the labor seems high.

Bonus Tip: If this quadruplex is out of state, I’d highly recommend building a reliable local team (cleaners, handymen, etc.) and maybe consider hiring a co-host or VA to help with day-to-day tasks, especially if you scale up. 

I'd be seeking someone to fund the down payment of the deal and I would be responsible for property management/bringing in funds for initial renovations for a profit/split.

They have no 2-factor authentication and don't email you to confirm that you want to update your login, both of which I'd consider industry standard these days.

I'd suggest that there is essentially no tax implication for this as compared to your alternatives.
