Megan O'Shaughnessy has maintained a determined presence at the top of the queue outside Millers Glen in Swords, county Dublin, since Tuesday.
But after four days dreaming of her new home, she and her fiance have had a change of heart.
The first time buyers are still buying one of the 60 newly built houses - but they're going to stretch their budget and try and land an even more expensive home.
"We're not going for the three-bed end terrace anymore, we plan to buy the three bed semi-detached now," the 23-year-old told Independent.ie
"It's about €10,000 more, but we're just thinking of the long term, and what we'll need in the future."
Millers Glen is a new development of 60 houses, consisting of two, three and four bed family homes.
Three-bedroom end terrace houses are on the market at €279,950.
Three-bedroom semis cost €289,950, while a four-bed detached house is selling for €399,950.
The young couple have saved €30,000 - 10pc of the house price they had originally planned to buy.
They secured a mortgage for the remaining €250,000.
But Megan believes that by eking out the additional cash from their savings, they'll reap the rewards in years to come.
Six other separate buyers were also eagerly sitting it out, determined to hit the ground running when the houses go on sale tomorrow. (Sat)
One mother, holding a place for her 23-year-old daughter, said a chronic shortage of second hand homes in Dublin has provoked a "bidding war" among first-time buyers.
"At least with this development the prices are set, and my daughter and her partner know exactly what they're getting," she said.
"It will cost exactly €279,950 for their home here - with second hand houses they were being constantly being outbidded."
The housing development - the first new housing estate in Swords since 2006 - opens to the public at 2pm tomorrow.
