Sounds like the house is sensibly priced if you have received decent offers.Depending on where you live and if you are moving up or sideways on the ladder, I might wait, OR
You could always ask the agent to phone them back and see if they will up the offer to the asking price ( you are paying them for this service make them work for their money.) Also consider who is in the best position : they have sold, short chain behind them, mortgage in principal approved. It is in the agents interest to make you wait for the asking price to up their commision for no effort on their part!
If the house you want is an absolute gem/ rariety the benefit certainly outweighs the loss. Have you asked for the house you want to be removed from the market.
