Definition
Lease-up is the process of increasing occupancy by signing new leases until a property reaches a targeted stabilized occupancy (and often stabilized rent levels). Lease-up can apply to new construction (a brand-new building) or a value-add / repositioning project where occupancy dropped due to renovations, poor management, or prior distress.
How Lease-Up Is Measured
Lease-up is typically tracked using occupancy and leasing velocity. Two different metrics are often used: physical occupancy (units occupied) and economic occupancy (rent collected as a percent of potential rent).
Common metrics
- Leasing velocity: net leases signed per week/month.
- Occupancy ramp: the month-by-month path from current occupancy to stabilized occupancy.
- Stabilization: often defined as ~90–95% occupancy sustained for a period (definition varies by investor and lender).
- Effective rent: rent net of concessions (critical during competitive lease-up).
- Traffic-to-lease conversion: leads → tours → applications → signed leases.
Why It Matters
Lease-up is where a large portion of the execution risk lives. If lease-up is slower than expected or requires heavier concessions, cash flow suffers and refinance/sale timing can slip. Lenders and equity investors pay close attention to lease-up assumptions because they directly affect NOI, debt service coverage, and the ability to reach a takeout or disposition.
Investor Uses
- Underwriting: model occupancy ramp, rent assumptions, concessions, and loss-to-lease.
- Capital planning: estimate working capital needs during the ramp (negative carry).
- Debt sizing: match loan structure to ramp period (often interest-only or reserve requirements).
- Operational strategy: set pricing, marketing, leasing staffing, and renewal strategy to hit targets.
Key Cost Categories During Lease-Up
- Concessions: free rent, move-in credits, waived fees, employer discounts.
- Marketing and advertising: listing services, paid search, signage, events.
- Leasing payroll: additional staffing and leasing commissions/bonuses.
- Turns and readiness: make-ready, cleaning, punch lists, appliance installs.
- Operating deficit: fixed expenses that persist while income is ramping (taxes, insurance, utilities, payroll).
Example
A 120-unit property is acquired at 70% occupancy (84 occupied units). The business plan targets 94% stabilized occupancy (113 occupied units). If the team achieves a net 6 leases per month, the remaining 29 units would take roughly:
- Months to stabilize = 29 ÷ 6 ≈ 4.8 months
In practice, underwriting should also consider seasonality, pricing changes, make-ready timing, and the likelihood of additional move-outs during the ramp.
Common Pitfalls
- Confusing signed leases with occupied units: a lease signed today may not move-in for weeks.
- Ignoring seasonality: many markets lease faster in spring/summer than winter.
- Underestimating concessions: fast lease-up can be purchased with discounts that reduce NOI.
- Overlooking make-ready bottlenecks: units can’t lease if they aren’t rent-ready.
- Using market rent instead of effective rent: underwriting should reflect net rent after concessions.
- Not funding working capital: lease-up often requires cash reserves to cover operating deficits.
