3. $130 million: Beekman Place and East 51st Street – New York, New York (10022)

Moving out to New York and into the more than $100 million range, we come to this eight-bedroom, 10-full bath co-op in the heart of New York City’s Midtown. Listed at $130 million on Trulia, The Residence at River House is up for sale for the first time in its 82-year history. According to its posting, it will be the largest single-family home in New York City thanks to a 62,000-square-foot renovated plan designed by Tony Ingrao, but no buyers have made it theirs yet; it’s been listed on Trulia for 52 days now.

Nonetheless, the estate was built in 1931 and offers a private entrance for residents, a garden/leisure level, a staff level, and a bedroom level.
