As for taxes, you will very much want to look up all your records and count all the capital costs to add to your original base value to reduce the amount of capital gains you will owe. If you are married or your spouse died within 2 years of the sale, you will get a $500,000 allowance before having to pay capital gains on anything above that. If you are single, you will have only $250,000 off the sale before having to pay capital gains. So every bit you can add to the basis is very important in your case.
