One way for a young family to get the most home for their money is to purchase a "distressed" property. With research and due diligence, you may just end up with a larger or nicer home than you thought you could afford, but without the extra price tag. One way to accomplish this is by purchasing a property that is in foreclosure.
How does this benefit you? Well, more than likely the previous owners of the property have been making payments on it for some time, bringing down the amount the bank was owed and increasing the equity in the property. Since the bank is only concerned about recouping what they are owed and not really attempting to make a profit, then you can essentially reap the benefit of the equity in the property and purchase the home for what is owed which is likely well below current market value.
Judging from the reader's e-mail it appears that he works for a major bank and is adamant about Buy & Hold and Dollar Cost Averaging. Maybe it's the approach he has chosen and he doesn't like hearing that the emperor is wearing no clothes. Nothing personal, honestly, but I find it incomprehensible that anyone, after the bear market and the financial disasters most people experienced, can even consider such theories. The results are just too black & white.
