Investing from Dubai, confused on Bangalore broker tactics

POA ready, funds allocated – I'm based in Dubai and looking to invest in a 2BHK in Bangalore, probably Richmond Town side. My budget is around ₹1.2 Cr to ₹1.5 Cr for good rental yield. I saw some Jai Constructions projects online. Problem yeh hai ki, I can't do site visits easily. Brokers are hounding me, har koi bol raha they'll get the 'best deal'. But I'm hearing mixed things – some say direct builder se better negotiation hoti hai, others swear by brokers for market insights and hidden discounts. Kya sach mein brokers extra commission ke alawa kuch value add karte hain? Or should I just push the builder directly once I finalize a property? How much negotiation leverage do they actually have? Koi experience share karo please.
