Portfolio lending and other finance options

[Leo Johnson]

I paid cash for a property, and also did a full gut and rehab. I poured about $25k into the rehab making it worth about $65k-$70k.  I'm looking to refinance the property but got denied for a conventional loan due to my credit score not being up to par. Will a portfolio lender do a cash out refinance? What are some other options to consider? This property will be used as a rental.
