Where to begin......? It seems to me this guy is in hair-on-fire mode but the "advice", while addressing the car and adult-child over-subsidy problems, fails to give the needed face punch.
http://www.washingtonpost.com/news/get-there/wp/2015/03/13/before-retirement-a-plan-to-clear-90000-in-debt/"invest in a new hobby of remodeling old cars" -- No, just no. Cars as toys are even more of an expense than investment than regular cars for regular use.
"paying a car loan and its insurance for his daughter, who is working her way toward financial independence" and "Selling the house that his father left to him – the one his daughter is living in now would increase the living expenses for his daughter" -- Yeah, I bet those daughters are making big strides with parental subsidies like that.
"His monthly bills amount to about $4,000, including a $750 mortgage payment, about $600 on groceries, an average $580 on cable and utilities and about $600 on dining out and other cash purchases. His car payments add up to $950, and he has about $500 in minimum payments on his credit cards" -- I don't get this at all. Staunton is a pretty LCOL area and his home must be huge and absurdly inefficient to have utility bills that high. That also seems like a really high grocery bill for two people. The car payments are ludicrous, and based on his home and work locations he is commuting about 50 miles a day round trip.
