First home in Noida Extension: worried about resale timeline

Been looking for 8 months now and it's getting exhausting. Noida Extension mein ek 2BHK ya 3BHK chahiye, budget ₹80L tak hai. Godrej aur Gaursons ke projects dekhe hain Sector 150 aur 137 mein. Prices toh yaar, upar hi jaa rahe hain, lagta hai Jewar Airport ka hype sahi mein chal raha hai. My parents keep saying abhi sahi time hai but I'm honestly not sure. Mera main concern hai ki agar 5-7 saal baad bechna pada toh resale market kaisi hogi? Kya tab tak achha appreciation mil jayega? Ya phir I'll be stuck with it? Koi batao kitna time hold karna chahiye property for maximum gain? Ya phir kya abhi market peak pe hai already? Kuch log bolte hain FNG aur Aqua Line extension se aur badhega, but kitna aur? Should I wait ya abhi le lun?
