Tenants miraculously find ways to move or pay for things when they learn you don't care about their hard luck stories.  

You'll get back to them next week, kind of thing.Then, miraculously tell them you've decided not to charge them for the cost of the ruined furnace, but they need to agree in writing that they will not overload the circuits in the future and how about we just call it even - you won't charge them for the furnace and they will have to replace their own TV and suggest they plug everything into surge protector strips.And then, maybe you could be magnanimous and give them a couple surge protector strips to show them what a nice landlord you are :-)That's what I'd do. 

If this one miraculously does not cause issues for you.

Let's say I miraculously got the property for $262,865 and took a $10,000 assignment instead.  

I think it's miraculous how many trillions our economy has absorbed without inflation since 2008. 

So a day goes by and he comes back to say that he talked to his agent and he miraculously found a buyer within 24 hours at $275k and wants us to match that offer.
