I inherited a partnership in a 22 unit commercial building with 8 restaurants, a grocery store, a couple of personal care services, and various other businesses.

But, you need to talk directly to the person whose name is on title. 

For comparison, a Navy Federal FCU personal loan will be in the 15s%

(Either with the roofing company, a heloc, or a personal loan.)Either way you will probably be way ahead on interest saved unless you have a sub 6% interest rate.

I try not to let it get personal...there are some members that have been 'inappropriate' in the past, but I will still give them a vote if their post actually deserves it

Personally, I would pay off the higher rate first. 

I’ve had a few “Gurus” personally try to recruit me into $20K+/year mentorships at networking events, along with paid workshops and masterminds.

My personal opinion is that, while shifting investments into real estate may be the right move for your situation, there is likely a lot of work to be done before you get to that step to avoid a potentially costly mistake. 

I'm hoping for some input on the best way to write up the lease contracts, as that is my next personal assignment.

When the deadline approaches you need a person to push it through in time.
