Gurugram Affordable Housing: Missed the boat?

Visited a couple of Affordable Housing projects near Sohna Road last weekend. My first property hai, toh thoda nervous hoon. Builders bol rahe hain prices will only go up, but pichle 1-2 saal mein already kaafi badh gaye hain, right? Matlab, is it still a good time to buy in Affordable Housing Projects, ya wait karna theek rahega? My budget is strict, so ROI matters a lot. Not sure if I missed the bus already. Any thoughts on price trends?
