41 per cent of first time buyers in the Dublin commuter belt area are buying outside of their home county.
According to the Banking and Payments Federation, more than three quarters of people buying in the counties surrounding the capital are moving from Dublin.
The figures come as the Central Bank yesterday decided not to make any changes to mortgage lending rules, which limit the amount people can borrow.
The organisation is warning that rising house prices are seriously limiting the ability of people to buy houses close to where they work or currently live.
Economist Ali Ugur says the commuter belt 'drift' puts pressure on amenities in counties such as Louth, Meath, Kildare and Wicklow:
"Housing is just one component of the overall infrastructure and once you put housing you need to put transport and obviously education."
The latest Housing Market Monitor from the federation shows housing supply continued its upward trend in quarter 3 of 2019, that was mainly driven by a significant increase in apartment building.
The number of apartment completions increased by around 81 percent during the three months, compared with the same period in 2018.
That's the highest share since 2011 when the current CSO data series began.
