Kharar investment: RERA discrepancies are confusing me

Budget finalized, loan pre-approved – ab Kharar mein atak gaya hoon. Sab bolte hain investment ke liye accha hai, but honestly, builder brochures aur site pe jo dikhate hain na, it's so different. Ek project mein toh RERA website pe kuch aur hai, aur sales team kuch aur bol rahi hai about possession date. Ab samajh nahi aa raha, is it even a good long-term investment agar pehle se hi itni discrepancy hai? What's the real ground reality for investment in Kharar? Kya ye sab common hai? Koi advice please.
