People spend so much time and effort moaning about stamp duty, even though the money goes to government to pay for valuable public goods (such as health, defence, roads, infrastructure etc).
Meanwhile moving house involves other hefty costs, the worst one of which is paying the estate agent's fee when selling, which is usually 1% of the selling price (though some agents will negotiate a flat fee). In London this is as much as 2.5% of selling price. I have very little sympathy for estate agents saying that the government package "isn't enough". If they want sales, they should slash their fees.
It's weird we've got into a situation where people think paying 1% in stamp duty which goes to govt to purchase valuable public goods = bad, but paying 1% of selling price to rip off estate agent = good. It should be the other way round, as you don't get similar value for money from the estate agent fee - all they do is take some people round your home (and nine times out of ten you have to do this yourself).
My advice to home movers - if you want to cut your costs, bargain mercilessly with the estate agent over their fees. You can also use the online DIY sites such as mypropertyforsale.co.uk, where you list your home for £99, and arrange your sale privately.
