Good luck, and welcome!
100 hours is about 2 1/2 weeks of vacation time. In trade off terms, that’s a pretty nifty trade to swap 2 1/2 weeks of your time and be debt free except for the house.
Having said that, when DH was let go from work in February he had just over 2 months of vacation. Between severance and vacation, we came away with almost 3 1/2 months of savings….and we needed that cushion to live on.
If you have extra vacation time beyond the 2 1/2 weeks, I’d say cash out the 100 hours. If you don’t, but your work allows you to switch shifts with someone in the event an emergency comes up, I’d still say go for it. Personally, I’d rather work for a year to accrue more vacation time than spend that same year (or more) paying off the car, especially when you could be debt free in the time it takes you to get the check from your company.
