For searching if the property is in the foreclosure process, search for your countys clerk of the circuit court website(probably will be linked to from the county site). Find a link to search the records online, many have a link to "mortgage foreclosures", if not, then search by the name of the owner and see if any cases have been filed against him/her.
For Hillsborough county where you are, the websites to search for properties is: http://www.hcpafl.org/CamaDisplay.aspx
For the county clerk it is: http://www.hillsclerk.com/publicweb/home.aspx
For foreclosures cases it is: ftp://www.hillsclerk.com/civil/foreclosure_list/.
Hope that helps!
