As a CPA, I'll confirm that all of the above are giving you correct info. One more tidbit. In order to deduct first and second home mortgage interest, the combined mortgage balances can't exceed 1,100,000.00. If it does, the interest deduction is prorated to the equivalent of a 1,100,000.00 maximum. The IRS has a worksheet to calculate this if it applies.
Also, re: your annuities, most of them have a provision that you can start taking monthly withdrawals at any time, up to a specified amount, penalty free, even if you are still in the initial penalty period. Just a thought if you were looking for funds to make a monthly payment on a MH. If you are looking for a large lump sum withdrawal, this wouldn't work for you.
