To this I say: WHO KNEW? (Answer: me, obviously!)
Somehow I have contorted the situation into being my issue (something about my house not appraising high enough so I had to do something to remedy the situation) and not his which resulted in much gnashing of teeth and near-ulcer inducing stress. So, per the recommendation of our Agent... we are proceeding as dictated by our signed and legally binding Purchase Agreement and heading towards our closing date of October 5th. Until we hear differently from them, its business as usual. And that thud you heard? It was the massive weight on my shoulders falling to the floor, through it and into the basement.
In the interest of full disclosure, this whole thing could fall apart like a house of cards, but we are prepared to put it back on the market (begrudgingly) to hopefully snag a less batshitcrazinsane buyer if need be. Our Agent is confident it will sell just fine, especially if we lower the price a bit ('round about the number where we would still break even).
So, color me relieved. As hokey as it sounds, I feel like someone has breathed life back into me... like I can finally focus on something, anything else. It is good to be back. Let's just hope its a nice long stay...
Thanks for your patience and kind words and support through all of this. Y'all are rock stars!
