In Kwasi Kwarteng's controversial mini budget, he announced that no tax is to be paid on properties up to the value of £250,000, a doubling of the previous threshold. Meanwhile the threshold for first time buyers has increased to £425,000, up by £125,000. It's certainly a bold move by the new Chancellor and one he says will be permanent, but what will the impact of these changes be on house buyers and the market in general?Under the new system, which came into immediate effect, the first £250,000 of a property's value will be exempt from taxation, after which a five per cent levy will be charged, rising to ten per cent over £925,000, topping 12 per cent over £1.5m. In real terms it means that those buying homes in the £250,000 to £925,000 bracket (which is the majority of home buyers in England) can expect to save £2,500 on stamp duty compared to previously.
