If your numbers are solid and I mean rock solid it might not be a smoking deal but I bet there is an investor that would put it in there portfolio. 

So I close on a multifamily property on Friday and one of the upstairs tenants smokes...my lease is non-smoking.

We are implementing a no smoking policy on a four unit we purchased last month.   

GO SMOKE-FREE!

Rule breakers don't feel comfortable renting from us and either don't apply or move on.We also have a strict "no smoking" policy, which doesn't allow smoking anywhere on the premises, and that alone weeds out many undesirable people and helps preserve the property.

Our clause: we can come in monthly (with notice) to inspect the smoke detectors.

I think the best appreciation plays in the county are more like Rockville and parts of Silver Spring, but you should get ok appreciation in Germantown.

The subtext of what your guy is saying is that he's moving to Colorado and hopes to work in a dispensary, but if he can't get a job, he'll just grow his own and sell it outside of the process.The laws in Colorado were set up to specifically discourage a bunch of out of state "businessmen" from coming in and "making you an offer you couldn't refuse".If I recall correctly, the principals of a MJ business in Colorado must have been Colorado residents for the prior two years.There are plenty of people in Colorado who neither smoke it nor grow it.  

There are places like Habitat to Restore which often have smoking deals on things you use for every rehab.
