Year-to-date pending sales are up 21.3 percent in June to 4,047, up from 3,337 in June 2014.

"The local market statistics halfway through the year are showing a very promising outlook. We expect interest rates to remain low at least through the summer, so it's a great time to invest in real estate in the Greater Lehigh Valley," said GLVR Chief Executive Officer Ryan Conrad.
