I work in real estate, but buying for myself is different

I work in real estate, but honestly, buying for myself is a whole different ballgame. Looking seriously at Saini Bhawan in Chandigarh for investment. The prices, ₹50L–₹8Cr, seem okay, but I know what builders don't tell you upfront. My big worry is RERA compliance. Is it fully compliant, ya any hidden issues that could delay possession or cause legal headaches later? I've seen too many projects get stuck. Also, what's the real delivery track record for this builder, specifically for Saini Bhawan? Not the brochure stuff, but actual ground reality. Lastly, what's the investor vs end-user ratio like? Don't want to buy into a ghost society with no community feel or rental demand. Any actual owners or channel partners here with off-the-record opinions? Trying to get honest insights on long-term ROI.
