I am not sure why do you need Real Estate Script for Indian market exclusively? Our script works with any language and we can import thousands of locations in India. It has flexibility like no other solution on internet and it is built to grow. We have several Indian customers and there has been no complaints about our software.
You can probably use any real estate scripts that is used anywhere in the world. I don't see the point of some thing specific to India.
