From 2BHK to villa: Yelahanka's real challenges

Something about Yelahanka doesn't add up to me. I'm in a 2BHK in Marathahalli, upgrading to 3BHK or villa. Home loan chal raha hai, so this next move is big. Yelahanka keeps coming up. But yaar, I'm worried about hidden risks. Connectivity and airport access are great, but water situation ka kya? Suna hai borewell dependency bahut hai, especially new projects mein. Aur PRR jaise infra projects ka noise aur dust? Temporary headache ya long-term issue banega? How do people check water sources and future development plans beyond builder brochures? Kya ground reality hai? What crucial due diligence steps do builders often hide? Is the 3BHK premium worth it if basic things are an issue? Any tips on spotting these red flags?
