Sheryl Crow -- All I Wanna Do ... Is Sell My Mansion For $16 Million

Sheryl Crow is unloading her rustic, Hollywood Hills estate for $16 million ... but there's a bright side to the hefty price-tag -- the property comes with not one ... but THREE HOUSES!!!

The 11 acre compound is listed for a cool $15,950,000 -- and boasts an infinity pool, a campsite area, hiking trails ... and ya know, a whopping 3 separate cribs.

House #1 (the main house) includes 4 bedrooms, 3.5 baths, Spanish-style architecture, a library, wine cellar and chef's kitchen.

House #2 is rocking 3 bedrooms, 3 baths, and panoramic views of Hollywood.

House #3 dates back to 1895 and has 2 bedrooms, 2 baths and an eagle claw tub ... um yeah.

So if you're keeping score, all in all you get ... 9 bedrooms, 8.5 baths, plus a bunch of rustic, outdoorsy stuff like canyon pathways ... a teepee ... and a palapa (which is a thatched roof dwelling).

We had to Google it too.
