@Blake LowdermanI would look deeply into the properties past rental performance. if the numbers are EXACTLY as you mentioned I would consider the deal.buying at these terms can be tempting but you have to make sure you are not "buying" some one else problems. definitely research the past years income and expanses and verify the numbers.I have personally dealt with properties in small towns like these - its a bumpy ride:-)

Enjoy the short lived niche opportunity while it lasts.... or has already passed.Even the local dispensaries won't want to deal with local growers because the consumer will soon want potency and purity testing, consistency, and name branding etc., and the dispensaries will stock what sells and that will be "Willie Nelson's Best Weed" and not your "grown down on 5th street" brand.
