Seeking real estate opportunities to invest in Joint Ventures or providing "Bridge Loans"   Prefer Florida but will do deals along east coast.

I've joint ventured with others to repair and sell later, I've rented them out, I've bought them for myself, I've wholesaled them....

All occupants age 18 and older will be held accountable to the terms of the rental agreement and be named jointly and severally liable.

I would contact all three tenants and tell them, they signed a joint contract to rent the property.

That may mean joint venturing with someone else and splitting profits to achieve that but any successful investor in it for the long haul realizes education and connections are an investment in your business and are vital in building your reputation in the industry on the right foot.  

@Mike YorkThey are jointly and severely liable.

Do a quick learn on joint and severable liability and add the necessary language to your contract for the next tenant(s). 

Joint Venture/Area Partner side, where we work with the seller and come in and fund the rehab(with no $ out of sellers pocket) and instead of the seller getting the as-is cash price, we go on to retail sell for "x" amount of dollars more..2.

A joint member LLC is treated differently because you're "inheriting" half a business, which owns the asset.

You could either open an LLC and structure it as a partnership or structure it as a Joint Venture which is less costly.
