I am trying to sell my house but despite many viewings, one thing in particular is putting people off. Our driveway is at the back of the property and accessed via a shared access road. As this access road is not owned by anyone it's not maintained and effectively a pot hole filled, dirt track. Some residents have filled some of the large holes with gravel but when it rains it is a mess. We don't have to walk down it to get into our house as there is access via the back garden but I'm not sure that the estate agents are making this clear to people. Regardless it is still off putting that the parking is down there. What, if anything can we do about this please? Is there anything relatively cheap that could fill the holes to flatten it out a bit? I have attached two pics, when it's dry it doesn't look too uneven but when we've had heavy rain it's awful. The rain picture doesn't show how bad it really gets.
