Anyone used a Portfolio/Private loan for investment property

[Todd Pippin]

Hi everyone,
I'm an investor that has filled up all my conventional loan spots and I have more properties that I have purchased in cash, rehabbed, and looking to pull my money out.  (Single Family) I'm having a hard time finding a legitimate portfolio or private lender that will do a fixed 30 year loan/cash out refi for these investment properties. 

I'm finding some companies out there, but not sure how legitimate they are.  Almost seems too good to be true regarding their rates/terms.

Haus Lending?

American Financial Network?

Any info or experiences would be great, appreciate it!
