The Hub's prime rental seasons is upon us like a stinky house guest. To further things along, we're introducing Vacancy Wire, a new mapping feature that tells you where the apartment open houses are in particular areas in as close to real time as possible. First up, the perennially coveted South End! Using data from our pals at Jumpshell, we've come up with three open houses available for touring Thursday starting at 5:30PM. It's all about the speed—at least until more vacancies open up.
