After Secret Wars, the Tower and Mansion were both sold off, the main team moved into a hangar in New Jersey, then the Baxter Building which was owned by Spider-Man at the time (the FF was gone and Reed believed dead), then GIRL's facility at Pym Labs. The Unity Squad used an abandoned movie theatre before taking back the Mansion thanks to Johnny Storm (using Reed's money). Sunspot's team had a couple of different bases. During No Surrender they all moved into the Mansion, but it got trashed again. At the end of that event it was restored, but the new team soon got the Celestial, so it was eventually turned back into a hotel. Janet Van Dyne created a bar called Jarvis Lounge to serve as an HQ, but that ended up being only a temporary replacement for the Celestial as they then moved into the Impossible City. The Fall of X Unity Squad never established a HQ.
