^ My exact reaction after reading this.

I probably would’ve tried to negotiate with the buyer to wait to move in a couple months later. That way at least if I was successful I could say to the tenants that “I’m trying to look out for them, but I need to sell this property”. 

But damn that sucks in a not-my-problem-but maybe-it-should-be kinda way

I'm a Realtor and can say this.

We can certainly negotiate through stuff like this. Post-occ is highly, highly inadvisable, but can be done.

But the better bet is what you said - "Hey, look - so here's the situation. My tenants have been there ***5 years*** and have always been really excellent to me, through thick and thin. Very reliable. ***insert horrible situation in tactful manner here.*** Would it be bad to request us move our closing date out to ***date XXYY***?"

And then go talk to the tenants ***in person*** and let them know about this stay of execution, you accept that it's hard, but also be sympathetic.
