Your question is unclear.
What happens on October 21? If it's a preforeclosure, you contact the owner. You can buy the property from him or her for the amount owed--which, with a foreclosure, would be the outstanding mortgages plus penalties, interest, and back payments. Let's say the house is worth $500,000. The owner owes $250,000 in mortgages, plus $20,000 in back payments, penalties, and interest. You can purchase the house for $270,000, and it's yours. (Use a Realtor for all of this. And time is very short. You'd need cash--either your cash, or money from a private investor or hard money lender.)
Unfortunately, today, a lot of properties going into foreclosure don't have any equity. In the example above, all the owner would have had to do is put the house on the market for, say, $450,000 (if it's really worth $500,000), and it'd have sold quickly. In today's market, with the scenario above with the owner owing $250,000 in mortgages--he probably bought 2-3 years ago, paid $250,000, and the house today is worth $150,000. So it wouldn't make sense to go in and buy a house worth $150,000 by spending $270,000.
In a short sale, you could offer $125,000 or so for the house and maybe get it. But short sales take months to transact. There isn't any time at all from now until October 21. And, working with that scenario, if the bank forecloses, when it comes back on the market with a Realtor, it'll probably be priced around $150,000. Not a bargain, but certainly less than you could buy it for today.
Hope that helps.
