The Vacancy Rate-Rent Paradox & Optimal Retention Strategy

Research from the National Bureau of Economic Research (NBER) analyzes the asymmetric friction of tenant turnover. Aggressive lease-renewal rent escalations frequently result in negative net cash flows over 24-month investment horizons due to turnover CapEx and unrecoverable vacancy drag.

Economic Cost of Unit Churn

• Unit turnover costs—including repainting, cleaning, marketing, and leasing commissions—average 1.5 to 2.5 months of gross contractual rent.
• A 5% renewal rent increase that triggers vacancy creates an unrecoverable 18-month payback lag compared to retaining a reliable tenant at current rent.
• Predictive renewal tracking initiated 90 days before lease expiration helps operators minimize last-minute vacancies and plan turnarounds well in advance.
