After the events of X-Men: Schism, Wolverine and half of the X-Men return to Westchester, New York and the X-Mansion. The name of the school is now the Jean Grey School for Higher Learning. Its grounds are in fact a spawn of Krakoa the Living Island. In the first issue of Wolverine and the X-Men an entirely new school is built on the grounds. It is funded mainly with scientific advancements by the students and diamonds from Krakoa.[9]

Under the All-New, All-Different Marvel re-branding, X-Haven was a sanctuary founded by Storm and her Extraordinary X-Men to protect mutants from the Terrigen Mist. The Jean Grey School for Higher Learning was temporarily teleported to a pocket dimension within Limbo with the help of Doctor Strange, the Scarlet Witch, and Wiccan. It also has magical defenses created by Magik to keep the Demons away.[11]

Following the War between the Inhumans and mutants which resulted in the destruction of the remaining Terrigen Cloud, Kitty Pryde, now the new Headmistress of the Jean Grey School for Higher Learning had Magik teleport the school back to Earth, more precisely to Central Park, New York City[12] and renames it as the Xavier Institute for Mutant Education and Outreach.[13] It was demolished after the events of Extermination.[14]

In the Age of Apocalypse reality, the remains of the X-Mansion were the headquarters for a mutant resistance cell against Apocalypse – a mutant that had conquered North America. The Mansion survives, and many new mutants come to the School in hope of shelter.[15]

In the darker continuity of Mutant X, the X-Mansion is run by Magneto, who had long ago taken up Professor X's dream. The mansion is vaporized in a nuclear explosion.

In issue #2, the X-Mansion is shown to be an orphanage for troubled kids that is run by Professor X and the teachers include Storm and Beast. Some of the orphans include kid versions of Deadpool, Scott Summers, Wolverine, Angel, and Colossus.[16]

In the Ultimate Marvel universe, the X-Mansion does not differ much. However, it is not entirely funded by inheritance. Though the school originally was funded from Magneto's inheritance, allowing them to neither accept nor seek out donations. Its policies have since changed after Magneto's departure and Xavier's subsequent control over the facility. Later, the students question and ridicule the unlikeliness of the facility simply being funded by inheritance. It is then revealed that numerous donors fund Xavier's projects and remain anonymous due to heavy anti-mutant sentiments present in public opinion. One of the biggest donors was the Hellfire Club, who were revealed to have an ulterior motive for doing so. In Xavier's conversation with Lilandra Neramani, it's discovered that S.H.I.E.L.D. were former financiers before their falling out with Xavier; it is unknown what their intentions were. The Church of the Shi'ar have become major investors.

The school's location is concealed by a projected image of a Jehovah's Witness chapter, as revealed in Ultimate X-Men #1.

The mansion is purposely demolished by Iceman in "Ultimate Requiem" following the events of the "Ultimatum" storyline. This is because the team had been devastated by Magneto's attack and the survivors were going on the run.
