HEMPSTEAD - Nassau County homeowners who missed the deadline for challenging their property assessments received an extension today.

One day after the original March 1 deadline, County Executive Ed Mangano (R-Nassau) announced an extension, giving everyone until April 23 to file their grievances.

"There were certain rules and regulations that had to be reviewed to make sure that we could extend this period of time," he says.

There was a group of about 12,000 mailed assessment letters that Mangano says were somehow damaged and sent out late. As News 12 Long Island has reported, many Nassau homeowners didn't receive their letters until February, leaving them scrambling to meet the original deadline.
