The owner of the suburban Albuquerque home from “Breaking Bad” ain’t budging on their nearly $4 mil price tag — claiming it’s a steal, especially since the next owner could cash in by turning it into the ultimate fan magnet!

TMZ spoke to current owner Joanne Padilla — whose late parents owned the famous pad — and she’s hoping whoever drops $3,995,000 on it will finally give fans what they’ve been dying for … turning it into a full-on museum.

Joanne tells us the 1,900-square-foot, 4-bed, 1-bath home could rake in some serious cash as a museum — even 12 years after the show ended. She says they still have an average of 300 carloads of fans a day from all over the world who come to New Mexico just to see it.

She’s convinced the place has so much potential, she could’ve slapped a way higher price tag on it — especially compared to other famous TV homes that have sold … but at this point, she’s ready to move on.
