The "Boom Clap" singer -- who also collaborated with Iggy Azalea on "Fancy" -- put her place on the market for a cool $3,650,000. The tri-level crib has 4 bedrooms, 4 bathrooms and tons of charm thanks to floor-to-ceiling diamond-paned windows, hand-carved dark wood doors and beams ... plus 3 brick fireplaces.

The whole home is 4,423 square feet with a pretty sick master suite ... featuring canted ceilings and a chic chandelier. Fan of speakeasy style? Check out the large lower level with its own entrance and movie theater.

There's lots of outdoor space too. Take the party outside to the expansive deck where there's a hot tub and surrounding gardens.
