What is Loss-to-Lease?
Loss-to-lease measures the difference between current in-place rents and prevailing market rents. It shows unrealized revenue potential when rents are below market or over-market risk when rents exceed current rates. This metric is often used in multifamily and commercial property analysis.
Why Loss-to-Lease Matters in Real Estate
Loss-to-lease matters in real estate because it directly impacts property valuation, investment strategy, and renewal planning. High loss-to-lease indicates potential for rent growth but also exposes owners to tenant turnover risk. Asset managers use loss-to-lease data to create phased renewal plans that balance growth and retention.
Example of Loss-to-Lease in Action
A multifamily portfolio shows average rents $200 below market. The owner implements a phased renewal strategy to capture higher rents gradually while minimizing turnover.
Key Takeaways
- Loss-to-lease highlights gaps between actual and market rents.
