Smart interim investment: Shree Green Court?

Sector 109 – been looking at this area for a potential investment property. I'm currently in a 2BHK in Sector 56 and honestly, evaluating options. Should I save more for that 3BHK upgrade I want, or add a smaller property like Shree Green Court to my portfolio for rental income? It's completed, which is a big plus, no construction delays ka tension. Price range ₹38.40 L–₹75.22 L seems okay. What's the actual rental yield like yahan? Log bolte hain 3-4% but real mein kitna milta hai? Capital appreciation potential kaisa hai for a completed project? Has its price moved significantly since launch? Aur iski resale market kitni liquid hai? Investors zyada hain ya end-users? Koi ghost society ka issue toh nahi hoga long term mein?
