A report published by the Daily Mail says house prices can be substantially lower in neighbourhoods adjacent to the UK’s most expensive postcodes. It claims that homebuyers who shift their search to nearby, less expensive areas can reduce the price of a property by up to 47%. The outlet frames the issue as a postcode “swap” effect: while the most desirable or fashionable addresses command higher prices, immediately surrounding areas may offer similar access to local amenities and transport links at a discount. The story emphasizes that the potential savings can be large, describing reductions as reaching “hundreds of thousands” of pounds depending on the location and property. The reporting does not provide detailed methodology or specific case studies in the supplied text, but it presents a general market pattern—prices fall when moving away from top-priced postcode areas to nearby postcodes. The underlying message is that adjusting the geographic radius of a property search can materially change costs.
