Well, after seeing the house, I have an update...It's still in perfect condition and I have just acquired 2 beds, 2 couches, a fridge, washer/dryer, 2 desks, a kitchen table, pots and pans, etc.

The business is booming - not just the pot smoking but also the edibles, creams, salves and the list goes on.  

You are right that any real estate investment has risks but you can mitigate much of that by deciding what you will and won't voluntarily take on.  

I think it could be worth offering quite a bit to entice them to leave voluntarily..What do you think is the maximum amount we could pay them, and still make it a good investment?

Even had a condo burn completely down because a tenant left a pot on the stove.

If a tenant becomes a problem, we can easily raise rent to cover our extra work or to encourage the tenant to voluntarily move out.  

It's certainly trickier to do it that way, but it is doable.Oh, and don't give up on trying to get them to move voluntarily. 

Now if I was to talk to the 2nd and 3rd and they agree on settling for 1/2 of their position on the property it would look like thisDelinquent amount and 1st remains the same2nd $ 27,0003rd $ 12,500Total $ 217,500I could sweeten the pot and offer $ 100,000 to the owners for the keys bring my grand total to $ 317,500Comparable sales as of 2-4 months ago is low to high $ 600,000.

A third option would be for each of us to throw more money into the pot.
