What Is a Lease Concession?
A lease concession is any benefit offered by a landlord to a prospective or existing tenant beyond the core lease terms, typically used to attract new tenants, accelerate lease-up in new or vacant properties, or retain existing tenants at renewal. Concessions reduce the landlord's effective income relative to the face rent stated in the lease.
Common concessions include free rent periods, tenant improvement (TI) allowances, reduced base rent for an initial term, moving allowances, parking waivers, and—in commercial leasing—assumptions of a tenant's obligations under their departing lease. Concessions are a normal feature of leasing activity, particularly in competitive or oversupplied markets, during the lease-up period of newly constructed buildings, or during periods of elevated vacancy rate.
Types of Concessions
Free Rent
The most prevalent concession. The landlord waives rent for a defined period—commonly one to three months for residential properties, and one to twelve months or more for large commercial tenants in long-term leases. Free rent is typically provided at the beginning of the lease term, allowing the tenant to occupy and build out the space before paying full rent. Some leases offer free rent distributed throughout the lease (e.g., every twelfth month is rent-free) rather than front-loaded.
Tenant Improvement Allowance
Particularly common in commercial leasing. The landlord provides a cash allowance—expressed in dollars per square foot—that the tenant uses to customize and fit out the leased space. The allowance may cover construction costs, furniture, technology infrastructure, or other approved improvement categories. See the tenant improvement article for detailed mechanics.
Reduced or Abated Base Rent
Rather than waiving rent entirely, some leases provide a stepped rent structure where the initial-year rent is below the stabilized rate, increasing over the first few years until reaching the full contracted level. This differs from an escalation clause in that it represents a below-market starting point rather than above-market growth from market-rate rent.
Moving Allowances and Lease Assumptions
In competitive commercial markets, landlords may offer to pay a new tenant's moving costs or to assume (buy out) the remaining obligations of the tenant's lease at their previous location. These concessions reduce the friction cost of relocating for the tenant.
Face Rent vs. Effective Rent
The central analytical consequence of concessions is the divergence between face rent and effective rent:
Face rent (also called asking rent or contract rent): The rent stated in the lease, payable during non-concession periods.
Effective rent: The actual economic value of the lease to the landlord, calculated by spreading total rent payments (after accounting for all concessions) over the full lease term.
For a 24-month lease at $2,500/month with two months of free rent:
Total income = 22 months × $2,500 = $55,000 Effective monthly rent = $55,000 / 24 = $2,292
The effective rent ($2,292) is what the landlord actually receives on a time-averaged basis, and it is the appropriate metric for comparing leases with different concession structures.
Concessions on the Rent Roll
A properly maintained rent roll should disclose concessions—specifically, which units or spaces are under free-rent periods, what the concession schedule is, and when full rent commences. When concessions are not disclosed, the rent roll appears to show strong occupancy rate and healthy income, but the actual cash collections are lower than represented.
This is a material due diligence issue: buyers relying on a rent roll to underwrite acquisition price should require disclosure of all in-place concessions and calculate effective rents to understand true current cash flow.
Concessions and Market Conditions
Concession activity reflects supply-demand dynamics:
- Tight market (low vacancy): Landlords have negotiating leverage; concessions are minimal or absent. Tenants may have to compete for available units.
- Soft market (high vacancy): Landlords offer concessions to attract tenants and reduce vacancy. Effective rents may fall significantly below face rents even as face rents appear stable.
- Lease-up period: New developments routinely offer concessions to achieve initial occupancy rapidly. The burn-off of concessions as the lease-up stabilizes is a key investor consideration—a property fully leased on paper but under heavy concessions has not yet reached stabilized income.
Concessions in Rent Control Jurisdictions
In rent-controlled markets, the interaction between concessions and regulated rent levels requires careful analysis. If a tenant is given a below-controlled-rent deal through a concession, some ordinances establish the concession-period rent as the regulated base, complicating future rent increases. Landlords in controlled markets should structure concessions carefully to avoid unintended rent base implications.
AI Tools and Concession Tracking
Property management and analytics platforms can track concession schedules, calculate effective rents automatically, and flag when free-rent periods expire and full collections should resume. Rentger and Propli support concession tracking within their rent management workflows. Maridesk provides operational dashboards that include concession visibility for property managers overseeing multiple units.
For investors analyzing markets where concession activity has risen, AI-driven market research tools can track the spread between asking and effective rents over time. The AI tools for real estate investors—market research solution page covers platforms that provide this type of market-level analysis.
