Higher education, medicine, farming, ranching, rail, mining, tourism, oil & gas, financial center, tax free shopping for Wyoming residents ;), Billings has it all. 

Take your medicine, learn your lesson, and get a better tenant (perhaps improve your screening process as was suggested in an earlier post - we use a third party verifier and the prospective tenant pays for the application - that alone screens a bunch of riff-raff from ever applying).Blessings!

I am in medicine so new to investing and finance.

Food and medicine or not. 

I'd suggest you take a pass...Would you let a doctor operate on you if he's "read about" modern medicine, but not seen a patient in 20+ years?
