Too little, too late. Bearing in mind that house buyers already pay the government to register their ownership with the Land Registry, this is an outmoded tax on the majority of the populace.
The average house price for a average family is probably, even at today's prices between £180K and £275K so the Government is giving nothing away.
It makes better sense for me for the Government, if they HAVE to tax us on property purchase, to raise the threshold on the lower end to £150K and on the higher end to £350K and then only charge the tax on the balance above the threshold. e.g. price of £340K tax 340-150= 90K Tax is £900. price of £1mil 1000-350= 650K Tax is £6500. Sure the government might lose a bit to waste on their useless projects and MPs expense accounts but what a way to kick start the market!!
I am in the middle of changing home, so far I had to drop £10K because people wern't prepared to pay the 3% tax as it was up at £260K then another £40K because of the market. Total loss £50K. Will the Government re-imburse me? Will they hell!!
