Want to land your dream home? Bring cash!

You've found the right house, you're approved for a loan, your credit score rocks, you have the down payment. Let's make a deal, right?

Not so fast. There's a deal-breaker in town and it's called "cash." Those who can buy a home with it are elbowing out those who can't. Turns out there are a lot of folks with cash to burn, especially in states where home prices tanked and foreclosed properties selling for less than $250,000 are plentiful. Foreclosures made up more than half of all sales of existing homes in Las Vegas and Phoenix in December, for example, according to MDA DataQuick.
