I realize state laws are changing around the country, but marijuana is still illegal in MN, and to top it off, he was the one who drove the couple to the unit.After they left the showing, we sent them an email saying that we noticed he was under the influence and we wouldn't feel comfortable approving them as tenants and our landlord would not either (he's a police officer).

I was convicted of felony possession of marijuana in early 2015.

That's because of the peculiarity of each unit.

Was I given bad information or is this simply something peculiar to the 401K?

I wouldn't buy a house with a basement since my experience has been that tenants sublet them or grow marijuana in them.The tenants in different areas are going to have different expectations.Storage space is always an issue when renting.

They are listed as the owner of a house that is being used as a marijuana operation along with SG Capital Partners L LC.

The tenants downstairs have complained of marijuana smell from upstairs several times already.

Medical marijuana patients can use edibles.

my Airbnb tenant is smoking marijuana in front of my house and then bringing girls to her rooms hahaha :) not just I got trouble from the neighbor but also another tenant, HOA and my wife. 

This may sound peculiar .
