You'd be better off contacting a local realtor in Seffner to find a home that is actually on the market for sale, instead of services like Realty Trac that entice you to pay to view these default notices, which any Realtor can do for you for free.
Thanks and I look forward to hearing from you,

The property you inquired about is just a notice of default - it could be a second loan or line of credit for 10k or could be the amount of money needed to be repaid in order to bring the loan current.
