The current average first-time buyer house price is 28% cheaper than the price paid by former occupiers, estate agent comparison site GetAgent has found.
The average first-time buyer house price is £193,701, while the average price paid by former owner-occupiers is £268,119.
Colby Short, founder and chief executive of GetAgent, said: “Of course, first-time buyers are always going to pay less, generally due to the size of the property and the fact they are a lot more willing to compromise on location and other property features in order to get that first foot on the ladder.
“But first-time buyer value isn’t just about the overall price tag of a home, it’s also how relatively affordable it is when compared to the wider area and while a £400,000 home may seem steep for first-time buyers in some areas of Great Britain, in the likes of South Bucks and Elmbridge it represents good value for money.
“Of course, schemes such as Help to Buy have provided a leg up for many but the inadvertent consequence of fuelling demand without addressing supply is that Help to Buy prices have actually shot up.
“So while there are many areas where a healthy gap can still be found, this isn’t the case across the board with some paying just 10% less than wider market value.”
In England, first-time buyers are currently paying 27% less than those already on the ladder, with this gap marginally smaller in Wales at 26%, but the highest in Scotland at 31%.
