Houses in national parks typically costs £119,000 more than elsewhere, Lloyds Bank research reveals.
The average house price in England and Wales’ 12 national parks is £360,671, compared to £241,959 for their surrounding counties.
New Forest is the most expensive national park with an average price of £577,979, 98% (£286,442) higher than properties in the surrounding area.
Snowdonia in Wales is the most affordable national park, with an average price of £173,170 – 3% cheaper than the surrounding area.
Andrew Mason, mortgage products director at Lloyds Bank, said: “Quality of life and an attractive environment are two major factors for people eyeing their next home move, and our National Parks provide both of these in abundance.
“It’s therefore not surprising to learn that many homemovers are prepared to pay a premium to live in some of the most beautiful parts of the country. These highly attractive areas are also very popular with second home purchasers.
“However, as some of the homes in these areas can cost as much as 15 times the local average wage, there is a risk that some people living and working in these areas could be priced out of the market.”
