There's something wrong with the idea of the average house owner thinking of his house as an investment, leveraged or no. This is a mistake I see repeatedly; comparing a working-class house owner to a rich fellow idly gambling with investments.
Primarily, a house is not an investment! Not in any social class I've ever belonged to, anyway; I can't speak for the folks on the hill. A house is something to live in; you have to live somewhere. The alternative to a low down payment house for low income folks is to rent. When you rent, of course, your payments just go up in smoke. Certainly I'd rather buy a house with a slightly higher-than-usual effective interest rate than rent a house.
