HELOC is harder to get for investment property but not impossible, similar LTV restraints but would work for lower dollar amounts, basically think of it as credit card backed by your house.You'll probably find that closing costs on a cashout might make small amounts seem unattractive... plus if the loans older you're going to have higher rates.

From my business school days in college, I specifically remember learning that a legal contract is anything two parties agree on, including a hand shake, so I wasn’t too worried about it.

I've never heard him suggest that one way or another I would expose myself legally from under my LLC. 

Explain in the letter that legal action will be taken to reclaim the amount they owe. 

Wholesaling is legal.

Corporations are considered separate legal entities, so the dealer status does not pass through to you as an individual.The other issue to consider is self-employment taxes. 

Trying to evict the tenant, but not sure what loopholes are available or if we should seek legal help! 

Nothing outside of apartment communities zoned MF in beachwood, but there is still a way to rent out a "room" legally in beachwood, and you don't have to do a yearly rental inspection ($500 annually!). 

It really depends.You also have to know if local zoning even allows an additional ADU and if so, can it be legally rented.

It is more of a legal question and I am not a lawyer, but from my experience, it doesn't really matter in which state you create an LLC since you will have to register your LLC in both states anyway.
