Lakshya Apartment: Real rental numbers, anyone?

Honestly not sure if I'm thinking straight with these prices. I'm scouting for a small investment property, alongside my own 2BHK upgrade plans. Lakshya Apartment ka ₹16-18L price dekh ke thoda confused hoon. It feels low for Delhi. Kya actual rental yield yahan se nikal payega? Matlab, real numbers kya hain, kitna expect kar sakte hain per month? Aur iske resale potential ka kya scene hai? Active secondary market hai ya ghost society ban jayegi? Investor ratio vs end-user ratio kya hai? Don't want to get stuck with something jo bikta hi nahi hai.
