Umm, lady? Your house did not appreciate by $100,000 in the last 3 years. You seem to have forgotten the insanely good deal YOU got on it. People know you are out of the country and left a beautiful house just sitting there. I imagine you will be getting all kinds of offers on the low side. Were you not prepared for that?
Do you have any idea how expensive that house is for this area? And, by the way, if I am planning on spending that much on a house, it damn well better have closet space.
I am glad I saw your fb rant (you probably want to make your page private while you are going through this) about the people who made the offer. You were a jerk.
