Some Type of partnership or a 50/50 LLC member ownership with his brother and can buy under that LLC because both of their credit scores are 700+, and3.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

You could use a home equity line of credit to put a down payment on your rental(s).

Assuming the person you have in mind has the capital and credit necessary to purchase the property and meet the lenders requirements, that would get a deal done.

This was a lot that was under contract for a purchase price of $500 and all in closing costs, hoa dues, back taxes, affidavit of heirship fees, was about ~$7300 to close and I used my business credit to purchase.Reason I purchased it was because all other "buyers" wanted to purchase at a super low price point where I wouldn't make any money.

I figure for now I would self manage sense I've had bad experiences with PM, one, being very slow at getting things resolved and two, the contractors they usually get seem to charge the highest rates possible!

I attribute this to bad information on the internet and “Gurus” who sell the novice investor on the notion anyone can scale to a  large portfolio quickly.

More so, going under contract and backing out on someone is a bad look and not one you want affecting your reputation starting out as a wholesaler.

Many PMCs will not charge if Class A property due to evictions being rare when tenant has 660+ credit scores. 

I know mobile home has a bad reputation therefore not that many people are doing it and the competition is not that big.
