Can you post an answer to the question and provide more data? Are you talking about foreclosures you see in a specific source online, or through some other means? Knowing where you are seeing the info would help me to answer the question better.
For your best interests, get your financing in order, and make a buyer representation agreement with a good REALTOR. Some of these deals can be a bit tricky, and someone who is experienced in foreclosed properties will be a valuable asset for you.
