Gurgaon RERA: paper tiger ya real deal

Honestly, even working in real estate, buying my own property is a different ball game. I'm looking at a project near Dwarka Expressway, and builder ka track record check karna is a headache. Everyone says RERA, but is HRERA truly effective ya sirf paper pe hai? Specially for builders like Lion Infra Developers, how do you guys actually verify their past project compliance? What title verification steps do common buyers miss? I know the super area vs carpet area games, but legal clarity is key for exit options. Kya Gurgaon mein RERA complaints se kuch hota hai? Any personal experiences?
