Some people are not cut out to be homeowners. I call them NOHOs. What distinguishes them is not their income, their mobility, or where they live — rather, it is how they live.
NOHOs live from week to week or month to month, depending on how often they are paid. Typically, they have nothing left at the end of the period, and if they run out early, they often borrow at high interest rates.
When they purchase durables, such as a TV set, NOHOs price the purchase in terms of the monthly payment, which they attempt to fit into their weekly or monthly budget.
