I have never been to New Ross but the minimum wage is €11.30, for a 39 hour week that is €440.70 or €1,908 per month. That is €3,816 for 2 people.
€1,200 is 31% of €3,816 so a couple,
on minimum wage, can rent a 2 bed apartment for just less than a third of their income.
According to
https://www.housingagency.ie/housing-information/affordability-calculator
Housing cost affordability is measured by looking at the proportion of household income that is spent each month to meet the basic cost of accommodation. This internationally used way of assessing housing cost affordability suggests spending
less than 35% of monthly disposable income on basic accommodation costs is generally affordable for most households.
Hardly a broken market.
