None of which I never actually met in person. 

My grandfather, along with his twin brother, were home builders who transitioned into building and managing a significant multi-family portfolio, which remains family managed to this day.With my personal family background, as an agent I have largely engaged in the multifamily space working with legacy owners in the sale of their properties - from 6 unit, single building properties to 19+ unit, multi-building properties.

can anyone you know in person vouch for this lender? 

Therefore, most lenders will require a personal guarantee.

I've found the people who want to charge for their time and "mentorship" typically need the money because they are struggling- maybe not the best person to take financial advice from. 

If someone injures themselves and sues, they will sue the LLC, not you personally.

Jeremy, I hope you don’t take this badly…..I noticed your posts don’t get much “traction” The reason is they read like slick marketing “puff” pieces you find posted on LinkedIn all the time, rather than personally engaged discussions, If you want significant engagement, just write something out, and don’t even “edit” it, just go with the first draft, giving the effect like a personal conversation with someone.  

I understand that each person's situation is different and unique and can appreciate the insight you all offered. 

Offer a personal guarantee (reduces investor risk if you have the balance sheet for a PG to be worth anything).  

You could use an LLC, Trust, personal name, etc.
