Cj,
The hyperlink below (be sure to scroll to the bottom of the page) lists an wide variety of grants (free money) for first time home buyers in Florida. Also be sure to check with the individual city you're interested in, because they sometimes have small unadvertised programs as well. Most importantly, use a mortgage professional familiar with these programs, because the paperwork can be tedious and complex. Of course, I also recommend a buyers agent to represent your interests solely. Get referrals from friends and family to find a good local REALTOR and lender in your area.
On a personal note, thanks for your work/service, and be careful out there. Best of luck and happy hunting! - Thu Jan 10, 2008
