    Questions about this listing

    Is 2399 UNION Boulevard in Islip still available?

    Inventory changes daily. 2399 UNION Boulevard is currently listed as Closed in OneKey® MLS. Contact East End Luxury Ltd. at (516) 449-2783 for the most up-to-date status, including any pending offers, auction date, or short-sale lender response.

    Can I tour a foreclosure or short sale on Long Island?

    Yes. Most distressed properties on Long Island, the Hamptons, and East End are available for showings by appointment. We coordinate access with the listing brokerage, asset manager, or seller's attorney and can typically schedule a tour within 24–72 hours.

    How do offers work on a short sale or REO listing?

    Short sales require lender approval and typically take 60–120 days from accepted offer to closing. REO/bank-owned listings follow asset-manager addenda and usually close in 30–45 days. Cash offers and pre-approved buyers receive priority. We guide you through every step.
