Stay healthy  give back  try to keep a good reputation in these days of social media  etc. 

Even the program in which I enrolled was a healthy chunk.

(Already investing ~20% of salary for retirement in various forms of the stock market) Even after putting 20% down, we should still have a healthy sum of money in the bank.

if healthy maybe trim well and watch close.  

Now with a more healthy market in Denver, it's hard to say whether those class C warehouses would have leased to non-MJ uses. 

You deserve to make a healthy profit if you can pull it off.If you dedicate yourself to a structured system I believe that you can create homeowners out of people who have simply never been properly educated to make responsible financial choices.

The upside is that from your post it seems that you bought it to hold and are now changing your mind only because you had tenant problems and your neighbor made an unsolicited offer to purchase and the return is healthy enough that it is prudent to consider it.  

Real estate will always be about jobs.Denver and Silicon Valley has such good appreciation due to the the healthy job market. 

All of my properties are not leveraged, and I maintain a healthy level of reserves, and I have a "day" job besides, so I'm probably a little less aggressive on rent levels, as I prefer easy, low-maintenance tenants to getting a few extra bucks and dealing with PITA tenants. 

Another option is to go the more traditional route using a real estate agent and searching for a fixer upper with upside pore too that is in good enough condition to qualify for traditional financing.
