Argh, after a long time looking we've just found a lovely house in a nice part of west london. Problem is, it's off market and being done up by a property developer with a bit of an ego. It is a 4 bedroom period property that he is doing up with an architect to a very high spec. We have been trying to do a deal with him and have made him a very good offer to keep it off the market (it will likely go to bids if it goes on the market). The offer we made was already over what the going rate is for similar houses in the road but he's come back and asked for a minimum of £1,000 per sq ft, Arguing that it is a unique product and there is nothing else like it on the market. what he's asking for is a whopping 30% more than its value had it not been done up to a high spec. Sad truth is, he will probably get the money he wants for it if it goes to market.
Do we try to negotiate further for this house we love, or do we accept that it is way overpriced and walk away?
