Average prices reached a record high of £266,000 in June 2021, £31,000 higher than the same time last year.
Sam Mitchell, chief executive of Strike, said:“House prices continued on their upwards trajectory in June, with the latest ONS figures capturing the final frenzy amongst buyers and sellers before the stamp duty holiday scaled back.
“Despite the tax break now only being available to properties under £250,000, there are still other factors at play that will likely contribute to further house price increases in the months ahead.
"Historically low interest rates, an uplift in 95% mortgages and savings accumulated during lockdowns are all going to allow more people to enter the market.
“Let’s also not forget that the UK is still faced with a major supply and demand imbalance issue.
"A lack of new stock that fails to meet the demand we see today is enough on its own to push prices up.
"Particularly when we all appear to be looking for the same thing – a desire for more space, bigger gardens, and that now essential home office.”
Hugh Gibbs, co-founder of SearchLand, added: “House prices always consume a lot of attention in the UK, and that is particularly true right now, with homebuyers, investors and developers eagerly waiting to see the impact of the first stamp duty holiday deadline. "Clearly, the ONS data shows us that even in the build-up to the deadline on 30 June, house price growth continued its rapid march upwards – although this is a trend that is unlikely to have continued into July and August. “The statistics underline that the stamp duty holiday has more than achieved its goals; it has incentivised a huge amount of transactional activity and fuelled growth across the property sector. "And, while the remarkable surge in property values over the past 14 months will eventually come to an end, the predictions of a sudden market crash this summer have certainly not come to fruition. “Make no mistake, the market remains highly competitive even as the stamp duty holiday tapers down, with desirable properties and land still attracting a great deal of attention from prospective buyers. Do not expect this to change any time soon.”
