About

Life in Bostonia

Living in Bostonia means settling into a compact, densely-built neighborhood in northeastern San Diego County where you're technically in the El Cajon area but navigating a split between city and unincorporated land—it's a quirk you'll notice when mail gets addressed to El Cajon even if you live just outside city limits. The median household income sits around $78,878, which is solid for the region, and housing costs reflect that reality: median rents hover near $2,087 monthly while homes average around $487,600, making it more affordable than many San Diego neighborhoods, though still a significant commitment. The job market is stable with unemployment at 4.6%, and you're looking at a manageable 25-minute commute for most people heading to larger employment centers.
