Re: Review of mortgage and savings
You have (by your estimated value) about 82% equity. What percentage would you need to have to avail of significantly better rates? How much of a saving would that rate present? How much of your savings would you need to achieve that rate?
You have a pot of €175k savings, supposing you look at getting the mortgage down to <60% LTV you need to spend at least €100k to achieve that. Only you can determine if the savings that will accrue to you by doing so will be worth the up-front cost.
The important question you need to ask yourself is what do you want to do with your money? Have you set any goals or have any plans as to how you want to use it? Do you wish to retire early? Set up your own business? Pay off your mortgage in ten years? Buy a yacht and sail around the Mediterranean? You don't need to answer those questions in public but you do need to sit down and look at what you expect your savings to do for you. Set out aspirations for the next two years, the next ten years, the next twenty years and then see how best you can use the money you have built up to work towards those achieving those aspirations.
As you have been a careful saver rather than an investor (based on the list you have supplied), if you are now looking at taking on more risk, perhaps give yourself a "play" fund out of your savings that you can use in a higher risk fashion, this will give you a learning ground to try out new investment patterns.
Good luck, well done and enjoy.
