My husband and I bought our first home at the height of the boom in 2006 for 360k. We moved out in 2019 and bought our current family home. We have about 165k remaining on the original mortgage (tracker currently 4%) and are getting about €1950 per month rent (repayments are 1695 a month, overpaying a little). We’re trying to decide whether we should sell now and pay a chunk off our primary residence mortgage and maybe put some money into pensions or hold on to it. With tax and maintenance we are not making any money on it so our feeling is that we should sell.
