As long as their dirtiness isn't causing any issues (like roaches, animal piss soaking into the floor, tobacco smoke/etc.) and they're not damaging anything I don't really care what the inside of their place looks like. 

At that point you'd need to get into education process about crops, see if you can swing something to get in on anything that would be more beneficial financially like a USDA tobacco base etc (that's just a girl from a farming family talking who does this personally) or something like wind turbines.

Bought a place that had a couple of HEAVY tobacco users previously owning it. 

Big burly guys with neck tats that drive jacked up 4x4s, chew tobacco for breakfast and smell like diesel fuel. 

Incidentally, there are both tobacco and marijuana smokers in that unit, and only medical MJ is currently legal in MD, which i really doubt is the case here…  I am considering reaching out to an attorney to better understand my options.

The key is details and a lot of labor (below also similar for tobacco, too).

Similarly, I have seen some manager's advertise all turn arounds take a set time (be it a 1 or 2 weeks or a month) but so much depends on the condition of the unit (think tobacco or cat urine), what it needs, and available resources (be it your time or a contractor's schedule)...My philosophy: it takes as long as it takes.

They smell like diesel fuel and chew tobacco in their sleep.
