That's despite the sale of the 30 properties not starting until tomorrow.
More first-time buyers have queued up today for houses being sold in Leixlip.
That's despite the sale of the 30 properties not starting until tomorrow.
People with young families have been sleeping in their cars, some for a number of days, in a "desperate" attempt to get on the property ladder.
The homes, some of which are selling for half a million euro, are being sold at Harpur Lane.
Kildare North TD Aidan Farrelly said it shows "the level of desperation that people feel when trying to buy a home in Ireland".
He said it's a "damning indictment of failed housing policy by successive governments", which has resulted in a chronic "under-supply" of homes.
“Some of the houses in this development cost close to or above the half a million-euro mark, yet the queues we are witnessing here today show the pent-up demand that exists – even for homes that are not affordable," he said.
Taoiseach Micheál Martin says the Government is taking steps to make sure incidents like this don't become more common.
