What kind of loan/mortage,lender should I use?

[Tarik Abdullah]

I have two rental properties free and clear of any mortages or liens with a combined value of $90,000. My problem is poor or "slow" credit. I have found a family member with better credit (750) that is willing to partner with me, he uses his credit or good name and I put up my properties. What kind of lender should we be looking for that would get us the best interest rate, on money, to fund our fix and flip deals?
