Since your wife is from Bangalore,then why dont you ask one of their people to check,but be carefull dealing with relatives,now a days we will be in very akward position when we come to know that they only have hiked the prices as to coverup tehir margins (Sorry telling out of experience) can trust good friends ask for refernce please don't go with real estate agents many cheat to the core,try good Builders with good track of record,ask their projects done,their properties developed,even if it is little more they will be professional.Every idle person is a real estate agent there,wants to make fastbuck with out hard work,we know how we slog to save every penny and sacrifice many things to save.
DONT GO WITH AGENT GO WITH A BUILDER OR DEVELOPER AFTER CHECKING THEIR TRACK RECORD.
