The Federal Reserve cut interest rates by three-quarters of a percentage point Tuesday, but don't expect mortgage rates to go down too. In fact, home loans could be heading higher.

Consider recent history: The Fed issued an emergency cut of short-term rates in early January, and then trimmed more just a few days later - but the 30-year fixed mortgage rate has responded by bouncing up from 5.6% to 6.4%.
