Hilary Duff's older sister, Haylie, is about to pocket $865k ... if she gets the asking price.
It's pretty incredible ... Haylie, who's an aspiring TV chef, bought the 3 bedroom, 3 bath Studio City pad only 18 months ago. She paid $1.33 million back then, but is now selling it for $2.195 mil.
The 3,150 sq foot home appears to have been updated. There's a sleek pool, plenty of outdoor space and a kitchen with 2 islands, which Haylie's gotta hate to see go.
