Talk this over with your Buyer's Agent and have them run comparable home sales prior to making an offer. Just throwing out numbers without facts to back them up is useless online.
There are at least two reasons the redemption period might be longer than 180 days. First if the property is more than 3 acres, And, if the home is involved in a court dispute with the government.
Some aspects of your question confuse me. My first piece of advice would be that you get a buyer's agent to protect your interests and guide you through this. Purchasing a foreclosure has some pitfalls that a regular purchase does not.
2. I don't think Coldwell Banker makes loans. They are are real estate brokerage.
3. The home could be in the redemption period, which is 180 days. Or is the sheriff's sale on March 19th? That would be the day the redemption period starts. Until the redemption period is over, you are negotiating with the current owner, not the bank. If he owes more than it is worth and he does not have the cash to bring to close, then he will have to ask the bank for a short sale.
4. Nobody can tell you now what the bank will take. My assumption is that it will be something close to market value.
5. Once it becomes an REO it will be listed, typically within a month or so of the bank getting it back.
