Help to Buy ISAs are available until 30 November 2019.
Reading is the most expensive area of the market where a 5% deposit using a Help to Buy ISA would allow borrowers to buy, estate agent comparison site GetAgent has found.
This is based on a deposit of £13,205 based on the current average house price.
With £13,250 and a 5% deposit, a Help to Buy ISA could help borrowers buy a house in 71.5% of areas in the UK.
Colby Short, founder and chief executive of GetAgent, said: “Help to Buy in its various forms certainly has its critics and while the original Help to Buy scheme has no doubt pushed up prices by fuelling demand without the additional supply, the ISA has at the least, spurred more people to save with one eye on climbing the ladder in the future.
“Unfortunately, this only goes a small way in bridging the huge affordability gap that keeps many priced out of the market and as a result, many are turning to much higher rates of loan-to-value in order to take their first step.
“Although the November deadline is looming to take out a Help to Buy ISA, you have until 30November 2029 to pay in and 1December 2030 to claim any bonus accrued, so it’s well worth looking into if you’re thinking of buying in the near future.”
East Dorset, Basildon and Aylesbury Vale are also amongst the best markets to buy with a Help to Buy ISA.
