We are expecting £10k inheritance. Can't decide best thing to do, I have £5000 car loan with a credit union, paying £120 over next 4 years at 9% but its not compound interest can pay off with no penalty. Mortgage is £80k at fixed 5.89% until September 2012 with huge £3k penalty if we leave, been overpaying by £90 per month and can overpay up to 5% of balance each year. Also have unexpected third child who is sharing with other gender teenage sibling, feel i want to try to convert our loft to bedroom for about £5K doing as much as we can ourselves. How would others use this bonus?
