Please visit the site in person, and post your about the builder. For NRI please join the owners community in facebook and post your query.
Now a days positive feedback are posted by there own IT.
From my past bad experiences, below are the lessons learned.
They do promises during the one on one but never ever keep the promises.
They never ever respond to eMail, delay payment interest is applicable for customer and not for builders.
Please dont dream about the amenities. Its always a dream for you.
Dream house they mean is to get the house in dream.
Please dont ask about the quality of construction or water provided during DLP period.
They never bother about the quality of the design. Since they are not going to stay.
Still the list goes on.
Please ask your relatives to visit one of the site which has been handover in last one as per the website. You can see that site might be under construction. This will show the gen-unity of the builder.
As per website 60% completion is completed.
