Kohinoor Famville rental yield claims are just builder talk?

Since last month I've been seriously checking out projects in Pune for investment, aur Kohinoor Famville kaafi attractive lag raha hai. Pre-launch se ab tak kitna appreciation hua hai actually? Builder toh bahut numbers dikha rahe hain, but real picture kya hai? Koi first-hand experience share kar sakta hai regarding price movement?. Also, rental yield ke baare mein kya lagta hai? Matlab, 1BHK ya 2BHK pe kitna expect kar sakte hain monthly? Builder ke track record pe bhi thoda doubt hai, on-time delivery ka record kaisa hai inka? Kya kisi ko delays ka experience hua hai inke previous projects mein? Honestly, long-term ROI ke liye sahi hai ya nahi, not sure. Is it worth buying now given the current pricing? Ya wait karna chahiye?
