HELOC or Mortgage with bad credit but 100% equity

[Kris Murphy]

Looking for advice on this:

I own a short term rental property with no debt (value ~250k) and would like to get a HELOC or even just cash out with a 15/30 year mortgage. My problem is that I have poor credit (under 600). I recently worked with a broker who said that because of my credit I was looking at 10% interest on a 1-2 year loan. Obviously that's not super helpful.

Any suggestions as to who would work with me to either set up a HELOC or reasonable long term mortgage?
