Rental potential isn't what brochures promise in Delhi

Rental yields in Delhi's high-end properties are barely worth the hassle these days. I'm so fed up of renting, finally looking to buy. Padam Punjabi Bagh looks great, but its total cost of ownership seems crazy. For Nirankari Affordable Floors, rental potential kitna hoga, honestly? Which one is a better investment for 5-year appreciation? EMI vs rent calculations are driving me mad.
