The hidden truth about resale flats for downsizers

Since selling our big family home last month, I'm finding it tough to buy a manageable, low-maintenance 2BHK in Noida Extension. Everyone glorifies new launches, but the resale market for ready-to-move flats in Sector 150 or 78 seems wild. Prices are almost matching new construction. Is finding a reasonably priced, good society resale flat impossible here? Change my mind.
