When buying a house, it’s a bad idea to make an offer based only on a first impression. Take this house in Hillingdon, Middlesex, for example. You would never want to buy this property, sight unseen. Although the multi-story house looks well-kept and attractive from the outside, once you cross the threshold it’s an entirely different story.At least with this kind of interior decorating, potential buyers would be able to negotiate a better price. That is, of course, this particular part of the country highly valued homes modeled after the one-eyed, one-horned, flyin’ purple people eater.
