Dear Richard: The real-time MLS data shows that the home is still active which means it does not have an "accepted" offer yet by the bank. The Bank does not want the home statused "Pending" until the addendum that they issue has been signed by them and the buyer.
So, to answer your question, if you want this home, make your "highest and best" offer and do it soon and base it on your agent's comparative market analysis. You'll need your agent to submit your offer with a pre-qualification letter from a Countrywide lender along with the as-is addendum for this home. It's a real good idea to go through the home yourself with a fine-tooth comb and a checklist and make sure you think the home's condition will meet your requirements, because although you can ask the bank to make repairs, they usually won't, so you want to make sure you like the home's condition.
Find youself a great agent to represent you if you don't already have one and GOOD LUCK!
