Property values surged 8.6 percent across Miami-Dade last year, priming local governments for a windfall in tax revenue in 2016 and offering another measure of a surging real estate market.
New estimates from the county’s Property Appraiser detail the second housing boom under way along the coast, with waterfront cities posting some of the largest gains. Sunny Isles Beach took
the top spot, with a 15.7 percent gain. No city saw more valuable new construction than Key Biscayne, which recorded an additional half-billion dollars’ worth of real estate when 2015 began.
