Nearly 5 million houses and condos, of which the mortgages are delinquent, will go through foreclosure over the next few years, a new study by John Burns Real Estate Consulting Inc. concludes.

This represents more than half of the 7.7 million households now behind on their mortgage payments. The situation is worst in Arizona, California, Florida, and Nevada. Burns calculates that there is an inventory equivalent to 27 months of sales in Orlando, 24 months in Miami, and 18 months in Las Vegas.

Consulting firm CEO John Burns says there is strong investor demand for these properties, so as long as employment continues to recover and interest rates remain moderate, these sales won't have much impact on overall prices.
