Thank you for your advice. However, I have done a lot of research into this over the last 6 months, and feel this is the way to go. Several of my family have been investing overseas over the last 2 years, and have seen excellent rewards on their initial investment as well as the guaranteed rental doing what it says on the tin. I would save over 200 euro a month by remortgaging and paying of what is left of the car loan. In five years, I should like to relocate, at which time I could either sell the current property in Ireland, or rent it out. The rental expected for a property in my area currently is 250 euro above the mortgage repayments for 100k.
My family will not require as much of my time after 5 years, and I can work full time. I was trying to keep the initial query relatively short and did not fill in these details. But you may rest assured these plans are not tentative and are backed up by research over the past years, more intensively over the last 6 months. There must be some way, other than selling, to realise the equity in my home, keeping in mind I have lived within my means and always made the books balance.
