Working in real estate, but buying for myself is a maze

Okay I'll be honest — I thought working in real estate would make buying my own place easy, especially in Sohna. Nope. It's a whole different game when it's your own money. I'm looking at Basai or maybe near Sohna Road for investment, eyeing a 2BHK. My budget is around ₹1.2 Cr, maybe stretching to ₹1.5 Cr for something really good. I'm trying to figure out if secondary market deals give more negotiation room than new launches. Builders like Candeo Projects or even M3M are firm on price, but brokers for resales sometimes seem more flexible. Are brokers actually getting better deals off-market, or is it all just commission games? Also, are there specific pockets in Sohna where prices are still genuinely under-corrected, away from the Golf Course Extension hype? Any real-world experiences on how much you could actually knock off in resale?
