San Diego and Miami offer distinct real estate investment profiles. San Diego has higher home prices ($989,750 median) and lower insurance costs, with 5.8% annual appreciation driven by supply constraints and a stable tenant base, ideal for long-term appreciation investors. Miami’s lower prices ($575,000 median) and higher rental yields (5-10%) suit cash flow investors despite higher insurance and climate risks. Both yield similar five-year ROI but cater to different investment strategies.
