Yelahanka upgrade search – what am I missing?

Yelahanka keeps coming up every time I shortlist something. Currently in a 2BHK in Marathahalli, thinking of upgrading to a 3BHK or villa. But yaar, Yelahanka mein hidden risks kya hain? Builders ka track record, water issues, ya connectivity problems? Already home loan chal raha hai, is the premium worth it? Any red flags?
