As the Federal Reserve winds down its intervention in the mortgage market, rates on home loans are generally expected to rise at least modestly during the rest of this year from today's unusually low levels. Some analysts believe mortgage rates will jump to around 6% by year end from 5% in recent weeks, while others see only a slight increase.

Meanwhile, federal tax credits available for some home buyers are due to expire at the end of April, adding to the sense of urgency many shoppers feel.

Since late 2008, 30-year fixed-rate mortgages have been available for people with strong credit records at around 5%, near the lowest levels since the 1950s, thanks to the Federal Reserve's heavy purchases of mortgage securities. At the end of March, the Fed is due to stop buying the securities. Most mortgage analysts think the immediate effect of the Fed's withdrawal will be modest.

What happens to interest rates over the rest of this year depends on many factors that are hard to predict, including the strength of the economy, Fed policies and foreign investors' willingness to buy U.S. debt.

Projections vary widely. At the lower end of the scale, analysts at Credit Suisse and FTN Financial Capital Markets forecast that mortgage rates will be in a range of roughly 5% to 5.25% at the end of 2010. Moody's Economy.com projects about 5.7%, and Barclays Capital 6%. Barclays cites a general rise in interest rates propelled by heavy government borrowing and a strengthening economy as the main factors.

Bottom line is that it is a good time to buy. But finding the right home should be your priority.
