Sector 93A overpriced? Resale value isn't guaranteed, I say!

Everyone glorifies 93A, but nobody talks about the high maintenance costs. Seriously, it's insane! Kids have moved out, don't need such a big place anymore. I'm thinking of selling my bigger house and buying a smaller flat there. But is it really worth the premium? Resale value bhi toh dekhni hai. Is it easy to sell if needed? What about waterlogging during monsoon? Change my mind. Disagree? Tell me why.
