Eyeing Ghaziabad 3BHK: Investor due diligence

Raj Nagar Extension – the appreciation numbers are tempting. I'm eyeing a 3BHK for investment. For builders like AMR Infrastructures, what critical RERA compliance checks should I do beyond just the registration? How can I verify their legal track record and ensure clear title deeds for projects like Mahadev Kaveri? Want to avoid issues affecting future exit options.
