Based on my experience as a buyer in the Kondapur project RV Panchajanya. There was been substantial delays in project completion which is still under construction.
Expect to speed up the registration which means pay the full money for an in-progress flat. Extra charges for even the smallest of change, and expect to additional charges when you get your furnishing like woodwork or false ceiling done.
Mr. Venkatram Reddy is a big pain to talk to as he does not see the difference between his labour and the customer(existing or even prospective).
This twice and speak to couple of the existing flat owners, as they tend to influence few to act against people who stand up against the inappropriate charges and defects.
