It looks a perfectly nice house to me, but I don't know what the prices are like in your area. Where I live (east London), you wouldn't get a decent flat for that price.
Personally, I am not keen on the two-level arrangement at the back of the house - not that good for families with young children - and it is a bit overlooked. I agree that the front of the house looks a bit shabby and unattractive. I'm sure that can be rectified. Apart from these issues, the interior of the house looks very nice to me, modern and well maintained.
Do you get any feedback from the agent and have you checked the prices of similar houses in the same sort of locality? I am sure it will be sold in time, but you may have to reduce the price if you find it is way out of line with other properties nearby.
