New Mortgage rules and the salary multiple cap

According to Rte the central bank rules for new buyers would be 10% on the first 220k then 20% thereafter so on a 300k house (not unrealistic in Dublin) you'd need a deposit of 38k which equates to 12.6%.
However there was a mention of a borrowing cap of 3.5 times salary so if you want to but that 300k house you will need a combined income of nearly 75k.
Hopefully house prices will reduce but even with the relaxed deposit rule for first time buyers the income multiple threshold may cut them out of the market.
