The Central Bank of Ireland has launched a public survey as part of its review of the policy framework around the restrictions on mortgage lending.
The curbs were put in place in 2015 to prevent another credit fueled house price bubble and put limits on how much people can borrow to buy a home.
Now the regulator is to conduct a deep review to ensure they remain fit for purpose for the future.
This is separate to the annual review which takes place later in the year.
As part of the process it is inviting members of the public to take part in a new online survey at centralbank.ie/survey.
The poll aims to tap into the public's views of the mortgage market and to ascertain what areas they think the review should focus on.
"Engagement with the public will be a core element of our review," said Director of Financial Stability, Vasileios Madouro.
"We know that behind the economic data and evidence that we look at, lie people’s own lived experiences."
"Understanding those experiences better will strengthen the effectiveness of our review. So I encourage people to complete our online survey."
The survey remains open until July 30.
The review is scheduled to continue into and through next year.
"The rule on how much people can borrow being linked solely to gross income rather than repayment capacity creates anomalies," said Kevin Johnston, CEO of the Credit Union Development Association, when represents over 50 credit unions.
"Furthermore, that mortgage measures disproportionately impact first time buyers, particularly single applicants, who are under further pressure to save a deposit to satisfy LTV rules."
Mr Johnston added that the Central Bank could consider switching to rules used in some other European countries where the mortgage borrowing limits are based on a maximum percentage of a person's net income that can be spent on all debt repayment including their mortgage.
