Prosperity Bank is offering a special 6-month CD with a yield of 4.35% APY. The minimum deposit is $5,000, and the maximum is $250,000. The special CD is only for personal deposits, and it's only offered in Volusia County. The special doesn't seem to be listed at the bank's website. It was advertised in today's Daytona Beach News Journal. The ad is available online here.
Volusia County branches are located in Ormond Beach, Daytona Beach and DeLand.
Properity Bank has some weak financial ratings for soundness: 2-star rating (problematic) at BauerFinancial and 1-star (lowest) at Bankrate.com. Both are based on 6/30/08 data. As I recommend with any bank, make sure you stay under the FDIC limits. The bank has been FDIC insured since 1984 (Certificate # 24963).
