A free rent period is a commercial lease concession in which the landlord waives base rent for a stated number of months, usually at the front of the term, to induce the tenant to sign. It lowers the tenant's effective cost while preserving the face rent that drives the landlord's valuation and cap rate math.
How Does a Free Rent Period Work?
A free rent period works by suspending the tenant's base rent obligation for a defined window written into the lease, most often the opening months of the term. The face rent, the headline rate per square foot, stays unchanged. Landlords prefer this to cutting the rate because the higher face rent supports property value, since valuation and cap rate calculations run off gross rent, not the discounted amount.
Three to five months of free rent is common on longer commercial leases, and a widely cited rule of thumb adds roughly one month of free rent for each additional year of term. Concessions have grown with vacancy. Avison Young found concessions reached 26% of lease terms in Q2 2024, meaning a tenant at a $100 per square foot face rate effectively received about $26 per square foot in free rent and improvement allowances.
Structure | How the abatement is applied | Typical use |
Front-loaded | All free months at the start of the term | Buildout and move-in period |
Spread | Free months distributed across each lease year | Softening annual cash outlay |
Gross vs net free rent | Gross waives base rent and operating charges; net waives base rent only | Net is more common, favors landlord |
Why a Free Rent Period Matters
A free rent period matters because it separates a lease's headline rate from its true economics. Two leases at the same face rent can carry different real costs once free months are counted. The operator translates concessions into net effective rent, the average rent actually paid over the full term after abatement and allowances, which is the figure underwriting and rent roll analysis should use.
The quotable point for an operator: free rent is a concession the landlord hides in plain sight, because it discounts the tenant's cost while leaving the face rent that governs the property's valuation untouched. A buyer reading a rent roll must confirm whether stated rents reflect free months already burned off or still owed, since an unexpired abatement is a future gap in collected income.
Example
A tenant signs a 5-year lease on 10,000 square feet at a $30.00 per square foot face rate, or $300,000 per year, with 4 months of free rent front-loaded. The table converts the concession into net effective rent.
Line | Calculation | Amount |
Gross rent over 5 years | $300,000 x 5 | $1,500,000 |
Free rent value | $300,000 / 12 x 4 months | $100,000 |
Rent actually paid | $1,500,000 minus $100,000 | $1,400,000 |
Net effective annual rent | $1,400,000 / 5 years | $280,000 |
Net effective rate per SF | $280,000 / 10,000 SF | $28.00 |
The 4 free months cut the effective rate from $30.00 to $28.00 per square foot, a 6.7% discount, while the face rent on the rent roll still reads $30.00. An underwriter who used the face rate would overstate income by $100,000 across the term.
Variations and Edge Cases
A free rent period is not a single clause: what it waives, when it applies, and whether it can be clawed back all change its value. The table below covers variants an operator should confirm.
Variant | Treatment |
Gross free rent | Waives base rent plus operating expenses and taxes; richer for the tenant |
Net free rent | Waives base rent only; tenant still pays operating charges during abatement |
Recapture on default | Some leases require repayment of unamortized free rent if the tenant defaults |
Conditioned on delivery | Free months may not start until the landlord delivers the space or a certificate of occupancy issues |
Spread abatement | Free months applied later in the term rather than up front, changing cash timing |
The common mistake is treating free rent as a pure gift. Many leases amortize the concession and let the landlord recover the unamortized balance if the tenant defaults, so a front-loaded abatement can convert into a liability.
Free Rent Period vs Rent Abatement
A free rent period is often confused with rent abatement, and they overlap, but the trigger differs. A free rent period is a negotiated concession, a suspension of rent the parties agree to up front as an inducement to sign. Rent abatement is the broader category of any rent reduction, including relief triggered later by an event such as casualty damage, a construction delay, or a co-tenancy failure.
The distinction is intent versus event. Free rent is planned deal economics, priced into net effective rent from day one. Abatement can also be a remedy the tenant earns when the landlord fails to deliver usable space, and that form is not a concession at all but compensation for a defect.
Frequently Asked Questions
How many months of free rent are typical in a commercial lease?Three to five months of free rent is common on longer commercial leases, and a widely used rule of thumb adds about one month of free rent for each additional year of term. Concessions rise with vacancy, so weaker markets and larger spaces command more. The exact amount is negotiated and written into the lease.
Does free rent lower the rent shown on a rent roll?No. A free rent period usually leaves the face rent on the rent roll unchanged, because landlords prefer to discount through free months rather than cut the rate, since valuation and cap rate math run off gross rent. The concession shows up only in net effective rent, not the headline rate.
Can a landlord take back free rent if the tenant defaults?Yes, in many leases. The free rent is amortized over the term, and if the tenant defaults, the landlord can recover the unamortized portion of the concession. Tenants should read whether an abatement is unconditional or subject to recapture before treating it as a permanent saving.
