Johannesburg is Africa's undisputed financial capital. Sandton — often called Africa's richest square mile — hosts the headquarters of multinational banks, law firms and investment houses, delivering commercial rental yields of 8–11% annually. Johannesburg's deep property market, institutional-grade infrastructure and established legal framework make it the premier destination for commercial, industrial and mixed-use real estate investment on the continent. Rosebank, Waterfall and Midrand are emerging growth nodes with strong capital appreciation prospects driven by new corporate campuses and transit-oriented development.
