Hyderabad's rental market is a bubble waiting to burst.

Rent in Uppal shot up 35% in just two years. I'm currently in a 2BHK nearby, thinking of upgrading to a 3BHK. Seeing these crazy rental hikes, I wonder if buying a second place for rental income still makes sense. Are landlords actually seeing good ROI or is it just inflated? Will these rents stabilise?
