A household is considered "cost-burdened" when it spends more than 30% of gross income on housing. Severely cost-burdened households spend over 50%. High cost-burden rates signal affordability stress that can dampen long-term population growth and ultimately constrain home price appreciation.

Why Cost Burden Matters for Investors
Markets with extreme cost burden (>50% of renters burdened) face long-term population pressure — people and companies eventually leave. Miami, LA, and San Francisco have seen net domestic outmigration for years despite positive international migration. This dynamic caps long-term growth potential even if short-term rental demand stays high.
