Which condos have financially strong HOAs?

Doubt you'll find any condo's on 30a for under $180,000. I don't know your requirements but, there are the Private Residence Clubs (fractional ownerships) at Watercolor, Rosemary, and Magnolia which might suit your needs for well under that price point. As for the financial strength of their reserves, you would have to look at their reports but I would think that the first two would be very strong and are managed by the same person (Jay Seine).

At this point they have all become fairly stable. Find a good agent and he/she can guide you. There are a few that are still going through some lawsuits that should resolve but even those seem to be stabilizing. The real trick is when you place an offer on a unit give yourself some time for due diligence. 10-14 days should be appropriate.
