Umang Winter Hills has a hidden resale challenge

Done with paying rent for years, finally taking the plunge into property investment. Looking at Umang Winter Hills, Sector 74A. It's a completed project, so delivery risk zero hai. But I'm wondering about the actual resale market for it. Is it liquid enough? What kind of capital appreciation have people seen since its launch? Builder ka track record on other projects kaisa hai for timely delivery? Any negotiation tricks for a completed project, like for PLCs or maintenance deposits? Hope this helps someone else too.
