Buyers on the hunt for a home in a fashionable postcode can save as much as 47 per cent – by looking in the area next door.House hunters can slash up to hundreds of thousands of pounds from the purchase price of their home by looking in areas neighbouring the most expensive locations across the country, fresh research from Lloyds Bank reveals.It looked at the most expensive areas in each region across the country and then looked at the cheapest neighbouring postcode that shares its border.Buyers are currently grappling with sky-high house prices, averaging £271,000 across the country, which has dented affordability and pushed many households away from their dream property.However, there's also been a rise of postcode envy, a term used to describe a desire to live in a prestigious address.But families after these stylish neighbourhoods could save 28 per cent on average by looking in less sought-after areas right next to chichi postcodes - with some able to cut the purchase price by 47 per cent. Here's where you can make the biggest savings. Wellesbourne, West Midlands, offers cheaper homes than trendy Leamington SpaBiggest postcode price gap is in the North EastThe North East region's most expensive location is NE26, which covers scenic Whitley Bay and Seaton Sluice in North Tyneside.Homeowners can enjoy the beautiful St Mary's Lighthouse and a Blue-Flag winning beach – but they must pay a hefty £304,022 for the privilege.However, if they instead shift their house hunt to NE24, which includes port town Blyth, they can snap up a property for £162,075 – a £141,947, or 47 per cent, saving.Of course, the area won't be exactly the same, but buyers will be just a 17-minute drive from the exclusive Whitley Bay.Amanda Bryden, head of mortgages at the bank, says: 'It's easy to focus on the must-have locations when you're searching for a home, but this highlights just how much value can sit right next door.'Of course, neighbouring areas aren't always directly comparable and each will have its own distinctive character, housing stock and local appeal. 'But in many parts of the country, looking just beyond the most sought-after postcodes can reveal more affordable options while still keeping buyers close to jobs, transport links, amenities and the communities that matter to them.''For first-time buyers in particular, a small shift in location could make a big difference – not just in getting on the ladder, but in what kind of property is within reach.'
