Greenbay or Dridha: My first home decision in Noida Ext.

What's the actual total cost of ownership for projects like Dridha Elite versus Greenbay Golf Village in Noida Extension? I'm a first-time buyer and honestly confused by all the hidden charges. Dridha is upcoming and cheaper, but Greenbay is ready. Beyond the initial price, what about stamp duty, interiors, and ongoing maintenance? Also, how's the metro connectivity from Greenbay for daily commutes? Green space is important too. Which one offers better long-term value for an end-user?
