Should I pay off my non-recourse loan?

[Harold Groetsema]

I'm sure this question might have been brought up in another post, but unfortunately I cannot find it. I own a duplex in a SDIRA with a non-recourse loan. In six months I will turn 59-1/2 years old, and am thinking of rolling over my current employers 401K to my SDIRA. Is it wise for me to then pay off the current non-recourse loan or keep it in place and invest into another property?
