Money magazine says "Hang on to your down payment money". Senior editor Walter Updegrave answers a question about what to do with house downpayment cash, "Let me be clear about this: Any money you're absolutely, positively going to need within the next two years -- whether to buy a house, pay college tuition, start a business, serve as an emergency reserve, whatever -- should not be invested in the stock market. Period." He adds, "Basically, cash equivalents where your principal isn't at risk. That pretty much means money-market funds, money-market accounts ... and short-term CDs (those with maturities of say, one-year or less)."
