Home-value growth has slowed and for-sale inventory is up, which is good news for home buyers. But mortgage rates continue to grow. According to Zillow, they’ve risen 0.7 percent this year, and most experts expect that trend to continue. If rates increase to 5.5 percent, it would eliminate an additional 5.4 percent of currently for-sale homes from a typical household’s budget. Prospective buyers in Denver, Las Vegas, and Sacramento would be the most affected by rising rates.
