convo with seller how did i go wrong?

[Account Closed]

Ok so a seller called me yesterday basically told me he was about to list with a realtor but had it rented out in mean time. He asked how I got his name i said I am looking to buy houses in your neighborhood and this was one of the one's I had looked up then asked him the address as I said multiple neighborhoods we looked in. I asked him about his house and what he would want for it he told me he was going to list with a realtor for 132500, I said for me to come in close quick, buy as-is and not collect realtor fees we buy at a discount etc. He said well what kind of discount, I said I would look more into it and he said well like 80k are we talking? I said if it is worth 130k or whatever he thinks I would offer around 90-100k he quickly said delete my number lol. Just wanted to know if I should have not told him a number or what I could have done better? Or maybe he simply wasn't motivated enough? thanks
