Developers are tapping the brakes on new condo sites in South Florida, wary of mounting inventory levels across the market. A September Miami Realtors report shows Miami-Dade has 14 months of condo inventory, more than twice the six-to-nine months seen as balanced. “That's a lot of inventory,” Two Roads Development partner Taylor Collins said on stage at the Waterford Business District. Miami’s condo inventory surged 25% over the past year, with listings up from 10,094 to 12,637 in August, according to the report. The result has been a condo market “doom loop” — units saddled with repair costs, dwindling values, higher association fees and soaring insurance premiums.
