Seattle-relo,
I’m sympathetic to your situation…but you seem to be blaming everyone but yourself. For such a large purchase maybe you should have done more homework before making the purchase. You have blamed:
1) The real estate agents.
2) The locals for being in denial of market conditions.
3) The seller for non-disclosure of problems.
4) The inspector for not finding problems.
It’s sounding like excuse after excuse with no personal accountability for your actions.
Sorry you’re in a bad situation…but no one held a gun to your head to buy the house.
