“Alan Fitzpatrick, vice president of lending operations at Habito, said: "This ONS data reflects the year of the Stamp Duty Holiday – from the first deadline in March, the extended deadline in June, and the lower threshold which was payable until the end of September.
"To put this incredible one-year price rise into more context, £27,000 would be the 2022 take-home salary post-tax, of someone earning £35,000 (more than the UK average full-time salary which is £31,285)."

Real estate experts say the high rate of growth is likely to let up in the coming months.
Karen Noye, mortgage expert at Quilter, said: “Any hopes of a downward tick in house prices have once again been dashed.
“While a reduction in house prices has not yet materialised, it seems inevitable that there will be a slowdown during the coming year and there are many factors currently at play that could contribute.
Michael Bruce, CEO and founder of property portal Boomin, commented: “While the scales of supply and demand remain firmly tipped in favour of the nation’s home sellers, there’s a good chance that the high rate of house price growth seen during the pandemic will now subside, replaced by more incremental gains during the year ahead.”
Sarah Coles, senior personal finance analyst at Hargreaves Lansdown, added: "Right now, there’s a floor under prices, because of the shortage of properties for sale, after a year and a half of buyer numbers rising and seller numbers falling.
"However, early indications from RICS are that the new year encouraged more sellers into the market, which should make life easier for buyers, but could weaken price rises."
