At least here in CO there's no such thing as a daily list. The get posted by the county once a week. Talk to some investors in your area and you'll probably find a local company that aggregrates counties in your area and sends out the lists as soon as they're available. Going to a REIA meeting is another good place to ask around and find such a company.
Otherwise, your source is the courthouse. Some counties have it online, though there my be a fee for a full list. If you can't find it online, go to the court house and talk to the folks there. They should be able to help you out. Even if it is online, these systems can be very obtuse.
