JMD Anand Height: What's the real delivery truth?

Builder delays are just a nightmare, it's such a scam sometimes. I'm looking at JMD Anand Height, around ₹52L, for investment. Currently in a 2BHK in Sector 150, thinking of upgrading for better ROI and capital appreciation. But seeing it's an upcoming project, I'm genuinely worried about their delivery track record. Are they known for delays? What's the real ground situation for RERA compliance here? I've heard horror stories about projects dragging on for years and messing up investor calculations. My existing home loan already restricts my options, can't afford more uncertainty. Has anyone invested with JMD before? Share your experience, please.
