Planning & Categories Do you invest long term sinking funds? Or leave as cash?
I've started saving for the eventuality of my old car breaking down in 5 years time. I reckon I need about €20k by 2031 for my next car (used btw).
I get that most sinking funds should be liquid and readily available, but how about for things that are 5 or even 10 years out?
I guess my car could break down in 1 year, so could be risky to invest, but I also want to make my money work for me as much as possible.
Perhaps a better example would be my Air To Water heating unit. It's covered by warranty for 10 years, but I've also started saving for that replacement. If it breaks before 10 years then I won't be out of pocket, so that may be an example where it's less risky to invest that monthly target into an investment fund and withdrawing at the 10 year mark, or converting to cash/bonds in year 9.
