Critical title checks buyers often overlook in Gurugram

Dwarka Expressway – this area has my attention for an investment flat. I work in real estate but buying for myself is different. Looking at a K Raheja Corp project, I need real insights on RERA compliance checks. What are the actual red flags beyond just registration? How do you verify a builder's clean legal track record, off the record? Also, what critical title verification steps do buyers often miss? I'm thinking about future exit options. Is an encumbrance certificate enough, or should I go deeper?
