David Spade Sells Beverly Hills Mansion for $19,500,000

David Spade just got a lot richer -- not that he needs the loot -- because he flipped his longtime Beverly Hills mansion and cashed in at $19.5 mil ... TMZ has learned.

For context ... David plunked down $4 million for the 4 bedroom, 7 bathroom home back in 2001, and you know what's happened to the housing market since then. True, he made a bunch of renovations, but still ...

The house is located in the super-exclusive Trousdale Estates in Bev Hills. A ton of stars make Trousdale their home, including Elton John, Ringo Starr and Charlie Puth. Among those who once lived there but are no longer living ...  Elvis Presley, Ray Charles and President Nixon.

The house is 6,426-sq ft ...  with sweeping, jetliner views from downtown L.A. to the blue Pacific

There are a bunch of bells and whistles, including a tennis court and an entertainment lounge.

Outside of its impressive looks, the mansion has a cool pedigree ... Prince, Eddie Murphy and Warren Beatty all lived there ... no, not all at once.

D.S. listed the house last month with Stuart Vetterick of Hilton & Hyland for $20 million, so it sold for just a skosh under asking.
