The issue is that you cant cold call people in New York 

If so make they have their earnest money held by the attorney and not the agents broker.

Lets go under at $800 so now monthly expenses are $3,800.

Call 3 references:  Verify that they work there, or that it is an actual person by asking where they work first, and don't mention who you are until after.

What would you do in my shoes I don’t invest there so take this with a slight grain of salt but I’ve heard multiple stories of basically this exact scenario someone getting offered a big payday for something in Cumberland, rejecting it & always for some reason (house burned down, block got worse, sheetz decided they actually didn’t want someone’s land for a car wash after all) always selling for like 10-20k and regretting not selling.
