The house has a "twin" that sold in August 2012 for the same price as our offer, but was in much better decorative condition internally.
I think it was a fair offer as it has been on the market for a while, houses in this area are not moving fast, most come down in price after a few weeks. I am not sure about raising the offer because I think I might be getting too "attached" (in poker terms)
I know I can't make them sell it to me, but do you think there is any point in mentioning the other house, what it went for?
