Definition
Loss to Lease is the difference between a property’s current in-place rents and higher achievable market rents.
It represents unrealized income potential that can be captured as leases renew or units turn over.
Basic Formula
Loss to Lease = Market Rent – In-Place Rent
Example
A unit is currently leased at $1,700 per month, but comparable units are leasing for $1,900 per month.
- Monthly loss to lease = $200
- Annual loss to lease per unit = $2,400
If 50 units are under market by $200 per month, total annual embedded upside equals $120,000.
Why It Matters to Investors
- Indicates embedded rent growth without relying on market appreciation
- Supports value-add business plans
- Improves Net Operating Income (NOI) over time
- Can increase property valuation through NOI expansion
How It Occurs
- Rapid market rent growth outpaces renewal increases
- Long-term leases signed below current market
- Conservative prior management
- Lease structures with delayed increases
Underwriting Considerations
- Analyze lease expiration schedule
- Evaluate tenant turnover assumptions
- Adjust for concessions and effective rent
- Avoid assuming instant mark-to-market across all units
Common Pitfalls
- Overestimating capture speed: Rent growth may require tenant turnover.
- Ignoring market softening: Market rent may decline before renewal.
- Underestimating renewal resistance: Tenants may negotiate or vacate.
- Failing to account for concessions: Effective rent may differ from face rent.
