As for the party on the 3rd floor, if they are breaking the lease by having unsanctioned pets, you can move to evict as well.As far as the weed goes, this is becoming a difficult grey area for me, as 'medical marijuana' is legal and getting a card seems to be trivial.

I've been looking at doing a little more in the stock market (i.e. options, new IPO's, robotics, lithium, Marijuana related investments, etc) as I've done quite well during the past 6 to 7 years.

No one else will make them submit to thatDrug tests are weak indicators of drug usage and tenant responsibility. drug tests are pretty much only good at picking up marijuana, and to deny someone a living space because of marijuana use is just crazy imo.

Are you sure he didn't have a prescription for medical marijuana?

There are weapons lying around, marijuana everywhere, all the windows are covered, he has cameras outside the house, ect.

A loaf of hearty wheat bread, a shack in the Bay View District, and that’s about it.When looking at Denver, it still has some potential for property value improvements, and commercial rental property is still a strong choice for those who don’t have a problem hosting a marijuana growing operation.

Also be wary of letter of intents as they are not legally binding, specifically as there is a current tenant in place, and I'd imagine you likely will not be able to get a signed contract in place from this potential tenant.If the borrower won't reveal who the tenant is, I think that might be red flag enough to turn this down.Just a thought, in Southern California, there are a lot of tenants who are willing to do this in the marijuana industry. 

Yes I understand that others doing business knowingly with a marijuana business could be found complicit in money laundering, or w/e. however I'd rather be open about it then not disclose that to potential associates.

Although much of this may be due to the recent change in our marijuana laws.

And I've seen medical marijuana businesses in these.
