After 6 months of house hunting we have finally seen a house that is almost perfect (could be a little larger and slightly further away from the road but I can live with that). Houses in this area only come up when people retire to somewhere else or die so not many have come up for sale. The problem is nothing like this house has been sold on the road for the last 20 years so the vendors have had a valuation and we have no recent like for like sales to compare it with. The asking price is at the top end of our budget and we're thinking of offering this just to seal the deal. Are we mad to do this or do some houses justify their asking price?
