Trailers go down in value rapidly. People who buy a $25,000 double-wide home will in five years owe $22,000 on a trailer worth $8,000. Financially, it’s like living in your new car. If I were to suggest you invest $25,000 into a mutual fund with a proven track record of dropping to $8,000 in just five years, you would look at me as if I had lost my mind.
