First time buying: The overwhelming start in Manesar

Manesar — I've been looking at properties here for a few months now. It's my first time buying, and honestly, the shortlisting process feels overwhelming. My parents keep saying location is key, but then how do you compare projects from different builders? Yashika Real Estate has a project I visited, but I wasn't sure what specific questions to ask or things to observe during the site visit beyond the basic amenities. Are there critical points I should add to my checklist? Also, regarding legal verification, I've heard bits about RERA and title checks. Is there a standard, comprehensive list of legal documents or steps a first-time buyer in Gurgaon should absolutely verify before committing? Any advice on this would be really helpful.
