Home to Houston, the largest city in Texas, Harris County is one of the nation’s most populous and economically diverse counties. Established in 1836, it was originally called Harrisburg County and renamed for John Richardson Harris. Its history includes shipping, oil, NASA’s Johnson Space Center, and a constant stream of migration that has made it a cultural crossroads. Today, it is overwhelmingly urban-suburban, though rural tracts remain on its northern and western edges. Housing options range from historic bungalows in The Heights, townhomes near downtown, and master-planned suburban communities in Katy and Cypress, to luxury estates in River Oaks and Memorial. Proximity to industries like energy, healthcare, aerospace, and shipping drives demand. Existing homes span widely—from $250,000 starter homes to multimillion-dollar estates. Suburban lots average $40,000–$70,000 per acre, while inner-city land for redevelopment is much higher. Harris County’s scale and diversity make it a real estate microcosm of Texas itself.
