This really is the key.
Your priority is to pay down your mortgage and build up plenty of equity to allow you to trade up when you want to.
So, only pay the minimum required into the pension. No AVCs or back dating.
On a salary of €80k, you will get a maximum mortgage of €280k.
At the moment, you have €60k between equity and savings.
So you could buy for €340k.
You need a deposit of €68k or 20% of €340k.
So it's very tight.
Build up equity or cash which will allow you to trade up. That is your absolute priority.
With more equity, you will have more choice of houses and more choice of mortgages and probably a lower rate.
When the trade up is sorted, you can start stuffing your pension fund.
