Home prices nationally rose 0.16% in February, when seasonally adjusted, according to Black Knight.
By fall, the rate shot over 7%, and home prices began cooling more quickly.
In December and January, however, mortgage rates began pulling back, and homebuyers were quick to take advantage.
"Conscious of changing mortgage rates, home buyers are taking advantage of any rate declines," Lawrence Yun, NAR's chief economist, said in the February sales release.
Mortgage rates began rising again in February and then fell back slightly in March due to market fears over the U.S. banking system, amid several bank collapses.
