There are only two ways, either you take help of an online real estate website or you go out on street and find property agents who can get you a decent house and in turn they'll take their commission.

Some of the online real estate websites from where you can start looking are:

1. www.99acres.com (I have had a bad experience with them, see here - http://snooptank.com/why-99acres-need-get-its-act-together-a...)

2. www.housing.com (The new rising star in Indian market)

3. www.sulekha.com

4. www.commonfloor.com

5. www.magicbricks.com
