A: The requirement is that you send the request to the address used by the board of directors or the President. There is no requirement that the board read your demand. Your demand is made whether they read it or not.
Time for an attorney to communicate with them once they have breached the statutory time limits.
A: great question -
If there is still a mortgage on the house, the first thing that will happen is the person at the mortgage company that is supposed to monitor these things may be fired.
Second is that the mortgage lien on the house is gone. You have no mortgage anymore - but neither do you own the house (unless it was YOU who bought the house at the tax deed sale, which raises more complex issues).
Third is that you STILL owe the money on the mortgage note to the lender.
If you have more questions - and I realize my answer may have raised more issues than you expected - contact a real estate attorney.
A: Not enough information but enough to see you need an attorney to review the contract and the events leading up to entering into the contract. Based on that review it should be able to be determined if you have a chance to get damages, or if you already purchased it, have you waived rights to sue for these deviations.
