When purchasing a resale flat in Kondapur, it's crucial to investigate if the land falls under Urban Land Ceiling (ULC) regulations. Even with an OC and building permit, a property's survey number might be subject to ULC. If the land is deemed surplus, it could be on the prohibited list, preventing registration. It's highly recommended to get a title search done by a local lawyer and ensure the land isn't on the Section 22-A prohibited list before finalising your purchase.
