The Central Bank is unlikely to make any changes to its mortgage lending rules when it reveals a review later today.
They determine how much banks can lend and the size of a deposit needed.
Currently first time buyers need a 10% deposit and can only borrow three-and-a-half times what they earn.
It comes as latest figures reveal house prices are rising by an average 13% across the country.
The Central Bank Governor Phillip Lane has previously indicated he's unlikely to change the rules.
