The cheapest house prices in the UK are now in the North of England, according to Nationwide, replacing Northern Ireland.
House prices in the North have fallen 1% over the past 12 months, whereas prices in Scotland and Northern Ireland have continued to grow.
The average house price in the North of England is now £123,914, while Northern Irish prices rose 1.6% to £128,562.
Overall, house prices in the UK rose 5.1% to £204,968 in the year to June, up from 4.7% in May.
On a monthly basis, prices grew 0.2% between May and June. The figures do not reflect any impact voting the result of the EU referendum.
Robert Gardner, Nationwide's chief economist, said: "Ultimately conditions in the housing market will be determined by conditions in the wider economy, especially the labour market.
"It is too early to assess the impact of the referendum vote on the economy."
East Anglia (5.5%), South West (5.6%), South East (8.8%), Outer Metropolitan (12.4%) and London (9.9%) all outpaced the UK average.
According to Nationwide, the gap between prices in the North and South also hit a record high in June. The gap almost hit £169,000, £24,000 more than a year ago.
