Capital appreciation in Sai Dham Greens is just marketing hype

Sai Dham Infra Projects Greens – I'm looking at this project for investment. Currently in a 2BHK in Sector 137, Noida, thinking of upgrading to a 3BHK here for better capital appreciation. But is the price jump worth it? My budget is around ₹60L max. Kya kisi ko idea hai iska actual capital appreciation forecast kya hai? Launch se ab tak prices kitne move hue hain? Aur rental yield ka kya scene hai yahan? Builders toh bahut kuch bolte hain, but ground reality mein kya milta hai? Also, resale market kitna liquid hai? Will it be easy to exit in 5-7 years? Already have a home loan, so ROI is critical.
