When we brought this place I had put in 3 offers on other places and got royaly dicked around. So I called the agent and went "My offer is 5k below asking range. Take it or leave it. Present it to your clients and if they agree you'll have the writing in offer 2 seconds after you call me. But Im not sending you a deposit to just talk to them". Turns out we were the only one, got it for 5k below the asking range (which even then was probably 10k too much). Worst case, they come back and say "Nah, how about X instead". But you never open negotiations high in the vendors favor. You miss 100% of the shots you dont take. Good luck!
