The average rate for a 30-year fixed home loan could rise steadily between now and the end of 2016.

Freddie Mac economists expect mortgage rates to "trend" upward through the second half of this year and into 2016, and the report also suggests some volatility in long-term interest rates when the Federal Reserve changes its stimulus policy, which may happen this fall.

The Federal Reserve has kept the federal funds rate near 0% in the past few years. It has done this to increase access to credit and accelerate the housing market toward recovery.

However, since the housing market and the economy are being resuscitated, the Federal Reserve officials are possibly planning on raising the funds rate. If this occurs, it would likely lead to an increase in mortgage rates, especially the long-term rates used for 30-year fixed home loans.

According to expert analysts, they expect the Federal Reserve to increase rates in the fall of 2015, which would coincide with its committee meeting in October 2015. If this does happen, higher mortgage borrowing costs could be seen toward the end of this year and into 2016.

So if you are looking to buy a home in the very near future, get locked in as soon as possible. Happy house hunting!
