re: question about commercial property I inherited and what to do with it

I'd love to keep it, its just the taxes, insurance and electric bill of this warehouse would be a lot for me if it were not making money, right now its covered, but I spoke with this tenant and he is retiring when his lease is up in February.

I can list it for rent again or I could sell it, Im sure neither happens quickly but I was thinking more of what can I do and maybe get out of teaching. It's a great opportunity if I can figure out how to do something with it and I'm trying to learn more about that.

I called a couple commercial brokers already and all seem too busy to call you back/answer an email. I think I reached out to maybe 7 and 2 replied.

I've read some about getting a NNN tenant online to come in, build them a place like a fast food restaurant and lease it to them, I'd love to do something like that if wife and I cash in our retirement accounts/borrow but again the realtors haven't been much help to this point, that's why I'm trying to figure out the best course of action online. Thanks again
