Jack it looks amazing and an excellent buy. But you really do need to market it properly for maximum audience to get a sale.
I would up the price (you can always come down!) to cover an estate agent's commission and get it with a decent agent on rightmove. You need the world to see it in order to get a sale - not a few select people on here and on an obscure website, that many have never heard of.
You also need a "For Sale" board outside. Did you know that up to 33% of buyers find their dream house by driving round the area in which they would like to live? it may be a negative point to you that you are 400 yards from the motorway, but may be a positive factor to someone else who otherwise would not be able to afford to live in your area. By the way - I think you're far too cheap. A property like that, with 2 acres, in the Golden Triangle of Yorkshire, would fetch about £750K! And Surrey is in another league altogether.
The agent will describe it however you want, but I'm pretty sure your description and photos will be enough to sell it. I would however, get them to put a floor plan on.
Do not choose the cheapest agent, or even the nearest. Look at the ads of some local ones and see if they appeal to you. Some will then clearly stand out as having no idea about how to market a house, as opposed to merely having it listed for sale. Examples of crap marketing are an unattractive photo of the front. You get one chance to make a first impression but so many agents take a full on picture showing only the extent of the front wall, with door and windows. By not standing back a bit and taking it sideways they may miss out the attractive front garden or the pleasant tree lined street, which immediately puts the house in a pleasant setting. Other common faults are pics of the bathroom/ en suite etc with toilet seat up and/or towels all over, stuff all over the kitchen surfaces, 3 photos of the same boring room that had nothing about in the 1st photo, and didn't look better in either of the other 2. If the agent is not sufficiently passionate enough to only show features that will attract the potential buyer to at least come and look at the property, then he's not going to put his all (limited though it may be) into selling it.
You may have gathered by this that I am into property and have learnt a lot over the past 40 years. I have used the same agent for the past 10 years and he is brilliant and passionate about property. When marketing he always puts the price as "offers over £x,000" and the last 2 properties we have actually achieved more than than asking price.
Another reason for using an agent is that it gives credibility to your asking price and also cushions you from the stupid offers that some people will start with. It is easy to take offence and fall out with someone over an insulting offer, when that person could end up ok after all and be the one to buy it.
Anyway, good luck with the sale. It's a lovely house.
