We put our house on the market recently. Before it went on the market the agent gave us a figure and told us his commission. The figure was in line with what we were told by other agents. Within the last couple week a few houses near us have gone above what was expected and now or agent is saying we are likely to get a higher figure but he is trying to push for higher then that. (New figure is 1.3 times old figure) and he's asked for a higher commission.
Is this normal?
