Lower home mortgatge rates in '83, experts say

The budding recovery in housing will blossom with the help of still lower mortgage interest rates - if competition for credit does not heat up when the economy turns around - some experts predict.

In the long run, analysts say, the trend that took mortgage loan rates down four points to about 13.5 percent in 1982 will continue. The 1982 improvement lowered by about $230 the monthly payments for a typical new house.

''I would imagine around 12 percent is where it's going to end up'' in 1983, says an economist of the National Association of Homebuilders, the largest housing industry trade group.
