Don't want to hang out in the county clerk's office just to find out about a recent home sale?

PropertyShark.com can do it for you.

The real estate Web site is now sending people out to Nassau County offices and courthouses to gather real estate data, including recent home sales, mortgage defaults and foreclosures, in an effort to ramp up the site's content.

Previously, the site relied on data obtained from the state, but that would often have a significant lag time, according to PropertyShark chief executive Ryan Slack. "We've decided that Nassau is a very high priority for us," Slack said. "It's worth getting the data in real time."

For now, PropertyShark has home sales from the past six months available on its site, and will be work to get data going back 10 years, Slack said.

PropertyShark started its records-driven Web site solely for New York City, but has since spread to Nassau, Westchester and other nearby counties.

Eventually, PropertyShark hopes to include Suffolk County data, but it will be a far slower process, Slack said, because the records are more difficult to obtain because it's not centralized.

PropertyShark's site is similar to one provided by the county itself at Mynassauproperty .com, but some of its data now looks to be more recent and detailed, according to an analysis of the two sites done by Newsday.

And unlike newer national sites like Zillow.com, PropertyShark doesn't provide its own calculated property values, instead sticking to the data in actual available records.

The site also will start sending people to Nassau foreclosure auctions in the county, to gather information about the process and the bidding, Slack said.

Through hands-on examination of records, Property Shark.com can also post more updated, detailed information on a home's ownership and title, as well as recent comparable sales data, Slack said.

In the future, the site also hopes to include other information, from building permits to violations, but that data is more difficult to obtain, as it involves dealing with each individual town and city in the county, Slack said.
