What nobody tells you about Rajkot pre-launch deals

Spent the whole Sunday checking out options near Kalawad Road and 150 Feet Ring Road. Family upgrade karna hai, kids bade ho rahe hain, so need at least a 3BHK. My wife's priority is a safe neighborhood aur achhe schools paas mein. Mota Mava, Nana Mava, ya University Road side kaisa hai for families? AIIMS aur Airport ka impact in areas pe kitna dikhega? I'm looking at some projects by Balaji Group, Madhav Group. Unka track record kaisa hai? Aur yeh pre-launch offers, kya sach mein deals hote hain ya bas builder ka trap hai? Not sure if it's worth blocking money so early. Resale market kaisa hai Rajkot mein? Should I worry about selling later if we need to upgrade again? Any advice would be great.
