Radar Logic, which tracks home sales and prices in 25 metro areas, found a solid rise in figures from February, which are now in, but analysts are not confident that it is a trend.
There was "strong growth in home sales" as transactions grew 22.9% month-over-month through Feb. 16, the report said. Radar Logic added that "the uptick in sales activity in 2012 was particularly robust" even though sales numbers usually go up in February.
However, "We believe that investment buying and mild weather are contributing to this strength, and both may be temporary," the company said.
The RPX Composite Price was up 1.9% over the month ending Feb. 16, to $172.84.
"The month-over-month increase was large relative to changes over the same period in years past," the report said. The company noted, however, "The RPX Composite price was 3.18% lower than it was a year prior."
