Found out tenants are getting divorced. Only husband is employed

[Kevin C.]

As the title states, we just found out today from the neighbors next to one of our properties that the tenants in our house are getting divorced. This poses a very serious potential problem for us because only the husband is employed. The wife is a stay at home mom. I want to head off any potential issues before they become more serious problems.

We were thinking of calling them up and telling them we need to come by to do the 6 month inspection (which is true) and while there, try to start a conversation with them on how they like the house, are there any improvements that can be made to it, are they happy, etc.. and reinforce what we've told them before, which is that if they have a problem, to please come to us and not just ignore the problem. That if they come to us before it becomes a huge issue, we can normally resolve it amicably. This would give us a chance to inspect the house and give them a chance to let us know if they're planning on abandoning the house. 

To complicate matters, if they are leaving, I want them gone now because in 2 months, the house will not be as desirable as it is now (Too many renters, not enough houses right now with school starting). 

Thoughts? How would you approach this situation if you had a heads up that you might be losing a tenant mid-lease?
