Noida's resale market for large flats feels dead.

Spent the whole weekend looking at 2BHKs in Sector 150 and Noida Extension. Kids have moved out, honestly don't need such a big place anymore. We want something manageable, low maintenance, with an elevator. But the resale of our current large 4BHK is taking ages. Is Noida's resale market for bigger flats just dead right now? Everyone talks about new projects, but selling older ones feels impossible. Should we just hold on, or is there a trick I'm missing?
