It is encouraging to find that, despite the rapid growth of mortgage debt, only a small fraction of households across the country have loan-to-value ratios greater than 90 percent. Thus, the vast majority of homeowners have a sizable equity cushion with which to absorb a potential decline in house prices. In addition, the LTVs for recent homebuyers appear to be lower in those states that have experienced the most explosive run-up in house prices and that, conceivably, could be at risk for the largest price reversal.
