The market is quite upbeat in Lincolnshire and you can see the sold signs going up all over. Location, Location. Location
I have just placed my house on the market, 2 x valuations of the same price and only £5k less than what my neighbour sold for in October 2007 (highest price point for this area).
It has nothing to do with governments etc. You will own and live in your house through many changes of governments, it's all down to available money. When the financial market crashed, lending stopped but banks are now starting to release money for mortgages.
I was offered a deal for a mortgage last week and only 3 days later it was bettered by 0.5% with the same company, due to the fact that more money had been released for the market place.
Your house is worth what someone is willing to pay for it, my advice is to market the property at the price you want rather than the price you are told.
Good Luck.
