Non-Recourse Loans, Best Lenders to Use?

[Dan Barman]

Am interested in using a non-recourse loan with my SDIRA to purchase investment properties and am wondering who are the best lenders to speak with? 

This is my first time doing this (I've used my SDIRA to buy property, but not with a loan). Any tips/advice etc. on terms to look for, general navigation of this method of financing would be most appreciated! 

Can I refinance or use a HELOC to leverage the equity from this type of property, or not possible with an SDIRA / non-recourse?

Thanks everyone!
