Michael Strahan hates to see her go, but he loves the look of $23 million in the bank -- so he's finally ready to part with his most beloved and prized ... L.A. area mansion.
TMZ Sports has learned the NFL Hall of Famer is pocket listing his Brentwood pad ... which buyers have been drooling over ever since Michael and Nicole Murphy broke up in August.
Our real estate sources tell us ... Michael is emotionally attached to the 15,600 sq. foot palace -- he just bought it in December for $16 million -- but recently decided he'll let it go IF, and only IF, he gets an offer of $23 million ... or more.
The spread includes 9 bedrooms and 14 baths ... but NOT Nicole. We're told she moved out back in the summer.
