Sheryl Crow -- Desperate to Sell L.A. Pad ... Knocks Off $2 Million!

Sheryl Crow REALLY wants to unload her Hollywood Hills mansion ... so much so she's offering a little incentive ... as in $2 MILLION OFF the original asking price, ahhhhhhh!!!

Unfortunately ... even with a discount ... it still costs a hefty $14 million. Awwwww.

TMZ broke the story ... Sheryl listed her rustic 11-acre-estate -- which contains THREE houses on one property -- back in October for $15,950,000. Turns out in this economy ... no takers.

Trying to spice things up ... Sheryl drastically reduced the price this month. So now the infinity pool, campsites, hiking trails, 3 separate abodes, wine cellar and palapas can all be yours ...
