My own property hunt: Kumbalgodu's ground reality

Visited a couple of projects in Kumbalgodu last week. Prices are tempting, but the commute is a big question mark. Metro extension kab tak aayega, aur usse daily office travel kitna improve hoga? I know builders don't always tell the full story. Also, water supply ka kya scene hai wahaan? Is it mostly borewell dependent, ya BWSSB connection bhi hai? Tanker dependency kitni hai? Buying for end-use, so these things matter a lot. Any real resident experiences please?
