Cash sales dominate the real estate market in South Florida.

In fact, RealtyTrac Vice President Daren Blomquist says the Miami metro area has the second-highest percentage of them in the country. (Another Florida area -- the Fort Meyers market -- comes in at number one.)

Blomquist says the numbers nationwide are high as well, with 43 percent of all home sales made in cash in the last four months.

Add low invetory to the mix, and Blomquist says the situation makes it more difficult for those who need financing to get make a purchase.
