I recently put in an offer on a lovely house which was accepted and have been going through the usual stages, paid for the survey etc and all looking good. Suddenly my mortgage lender, having done their valuation have now come back to say the property is worth 8k less than the price I've agreed.
As far as I know I can either stump up the extra cash myself (I don't have enough) or ask the sellers to reduce the price. We live in a very buoyant local housing market so I expect if I ask that they'll simply put the house back on the market and I'll lose it. 
How common is this to happen? Do I have any other options? I really don't want to lose the house as it's perfect for us and there's so little else available on the market.
