There is no price because this home is NOT for sale. You need to know that websites like Zillow, Trulia, etc. pay 3rd party vendors to copy information from public records at county buildings across the U.S. The listing does NOT say it's for sale. Scroll down and you will see Trulia just lists the facts that was given to them from Westchester County.
At this point, the home may be for sale in the future but there is no guarantee it will. Then again, the owner may end up paying all the late bills and continue to own the home.
If you are looking to buy a foreclosure or a home, you need to work with a local realtor in southern Westchester. Are you pre approved by a lender or will you be a cash buyer? Realtors in Westchester will ask to see a pre approval or proof of funds before showing you any homes.
