My Smartworld One DXP 2 investment dilemma

Been paying rent for over 10 years now and I'm honestly fed up. Landlord ne phir rent badha diya, so finally taking the plunge. Smartworld One DXP Phase 2 dekh raha hoon for investment, the 3.5 BHK units. Price point ₹6.30 Cr feels quite high, not sure if pre-launch mein itna hi tha ya kaafi badh gaya hai already. Iska capital appreciation forecast kya lagta hai? Aur resale market kitna liquid hai, matlab agar 5-7 saal mein exit karna ho toh buyer milenge kya? Under-construction project hai, toh delivery timeline ki reliability bhi dekhni padegi. Builder ka track record kaisa hai for on-time possession? ROI is key, so any insights on actual rental yields and future resale value would be super helpful.
