Check your couch cushions, kids, because you're gonna need every penny for this one: Jackie Kennedy Onassis' estate on Martha's Vineyard has hit the market with a hefty $65 million pricetag, reports CBS News. "Now that our children are grown, it is time for them to spread their wings, and for us to explore new places," daughter Caroline Kennedy tells the Vineyard Gazette. That $65 million will get you a 6,400-square-foot house on 340 acres on the vacation hotspot, as well as a guest house, pool, tennis court, and a boathouse. When the former first lady bought the Red Gate Farm back in 1979, it was a little more modest: It had only a hunting cabin and cost $1.1 million. It's something of an ecological gem, notes the Gazette, citing "stunningly beautiful windswept coastal dunes, wetlands, hillocks and salt-blasted heathlands."
