I have a partner that has flipped houses before but he just moved here a year ago and over time his credit isn't the best and he doesn't know any investors or any way of obtaining the funds.

Even if you figure one out, many lenders don't know and/or don't care about the exceptions, like being able to obtain a second FHA or rules for more than 4 mortgages, etc.

The alternative is she obtains the financing as a natural person and you vest title in the name of the LLC.

It's why banks don't follow this arrangement as they did in the old days.To obtain profits, you need to participate in the partnership, active or passively, and loan the money to that entity, not as an outside lender.

Impressive, but I have a hard time believing any mortgage broker would set up such a deal even with the most naïve of his or her clients.I would also suggest you not use any form of transactional, hard, or private money until you are certain you can make those payments and also know positively you’ll be able to obtain a traditional loan.

Has anyone been successful obtaining a mortgage from a traditional lender without having a credit score?

They should be paying rent to the listing agent & therefore she should have obtained a copy of the lease or rental agreement.

What about obtaining the deposits the PM has received?

If the buyer and seller don't come to agreement and/or settlement, the EM will sit there until one of the parties sues the other and obtains a judgment.  

I recently obtained a judgement against a tenant who stopped paying rent.
