The condo community has to be on the approved list you can find at HUD.gov. Sorry but this site won't allow me to post the direct link for you.
HUD has guidelines that must be met by the condo community, things such as number of investor owners, number of units delinquent on fees, required reserve funds for major repairs and maintenance, adequate insurance coverage.
A lot of FL condos have too many rentals, too little in the reserve funds or insurance coverage is not sufficient to meet FHA guidelines. It also requires the condo board and management complete documents for HUD, which not all are willing to do. Some were previously approved but let the certification lapse. It makes it difficult for FHA buyers to purchase condos, but it's not impossible. As I mentioned at the top of my post, all approved condo communities must be on the HUD approved list, so that is where I would start my condo search.... by seeing what options are open to you in your area.
Good luck with your search.
