need an opinion on whether to finance my truck with my 401k or not. My rate is 8 percent which was high because I’m in the middle of selling a house, so my 401k payback is six percent interest paid back to myself. Thats 14 % swing if my math is right. I know my money wouldn’t be making money in the market but 14 % seems like a good deal. So what is my dumb ass missing?
