Thank you for the objective response, its a difficult thing to find on the web!
WRT debt aversion, we had hoped to clear the mortgage relatively early, but it was always a stretch goal, dependent on circumstance.
WRT social circle, BofM&D definitely is a significant factor for some. Not all, but a few circa 600-800k properties in the most desirable locations in Dublin, but there is no point in comparing with them, the circumstances are too different. Others have not and just took on more debt that we did.
WRT kids, we may have another.
WRT more utility, it depends. Primary area of potential benefit is proximity to a secondary school, as we are not particularly close to a secondary school which will become an issue in 10 years. A house with a bigger garden, shed etc would allow for more freedom for hobbies, but its not a big deal.
