NEW YORK (AP) — Defying the national housing slump, property values in New York City rose 19 percent last year, double the gain in 2005, according to the city's finance department.The biggest increases were in the Bronx and Brooklyn, where property values soared nearly 28 percent. Manhattan registered a 16.9 percent gain.

The figures are based on the annual assessment roll that includes market and assessed values for all property.

City officials said the total value of New York City real estate was $802.4 billion, up from $674.1 billion in 2005. The city has 980,911 taxable properties.

The most expensive building was the Time Warner Centre on Columbus Circle, with an estimated market value of $1.1 billion, up almost 10 percent from the previous year.

The assessment roll will help set taxes for the fiscal year beginning July 1.

"Taxes are likely to be up as a result of this," Finance Commissioner Martha Stark said.
