According to the Nassau County Executive Laura Curran, the homes sales have surged due to the pent up demand as showings finally re-opened. But additionally, prices island-wide are up 5%, and 5.55% in Nassau. And along the North Shore, that number jumps to nearly 9%.
"We're also talking with school districts to see what their enrollment looks like," Curran said. "Whether it's going up or down, and what they might need in terms of help."
Experts say millennials are driving the new wave -- those on the older side, in their 30s, with families, but still looking to get out and enjoy eating and shopping.
"And these walkable, vibrant downtowns are a real key to that," Curran said. "That's what young people are really looking for."

Safety in all forms is the top priority.
