'Breaking Bad' Star Bob Odenkirk -- You Want A Real Estate Lesson? ... Better Call Saul

Bob Odenkirk made a career playing a guy who protected drug kingpins and their money on "Breaking Bad" ... and now he's ready to cash in legitimately in real life.

The actor who played Walter White's shady lawyer Saul Goodman on BB just listed his home for $2.5 million ... not bad, because he bought it in '98 for $675K.

The single-level house is in the same exclusive Oaks area of Los Feliz -- home to celebs like Brad Pitt and Angelina Jolie, Zac Efron, Jon Hamm, Alexander Skarsgard and Naya Rivera.

It vaguely resembles the Heisenberg's digs from the outside.

And one more celeb connection. Bob listed the house with real estate guru Sharona Alperin -- she's the inspiration for "My Sharona."
