What a waste of time. This site is useless. If you post your property for free. Your property will be visible for agents only for couple of days. And you will be bombarded by the agents only, no real customer.
After looking at 10 responses ( all from agents ). Your account will become chargeable. So nothing for free, only you can get the contacts of agents. Instead of posting on magicbrick, you can better directly approach agents.
