Effective Rent

Effective rent is the rent a lease produces after concessions and escalations are taken into account, expressed over a stated period. A free-rent period lowers what is collected while the stated rate stays the same, and escalations lift later years above the starting rate. Calculation practice varies by market, and some markets include broker commissions, so two effective rents are comparable only when the period and the included items match.

How free rent and escalations turn face rent into effective rent

Face rent is the rate written in the lease. Effective rent restates it after the lease’s concessions and escalations are spread across a chosen period, which gives one figure for what the lease yields per month or per year.

Free rent works by removing months of payment from the total while the stated rate stays unchanged. Escalations work the other way, because later years carry a higher rate and the average across the term sits above the starting rate. Where both appear in one lease, the two effects partly offset each other, and only a full schedule shows the net result.

The inclusions are where the figures diverge. Local practice differs on which costs enter the calculation, and in some markets broker commissions are counted. A quoted effective rent therefore carries an implicit definition, and that definition has to travel with the number or the number is ambiguous.

“Effective rent calculations may vary according to local market practices; for example, in some markets, broker commissions are included.”

Why net and gross leases need one expense basis before comparison

A net lease has the tenant paying a share of operating expenses on top of the stipulated rent. The rent line in that lease and the rent line in a lease that bundles expenses into one payment describe different things.

Effective rent adjusts for concessions and escalations. It does not convert a net rent into a gross one. Two leases can show the same effective rent and still leave the owner with different income after expenses, so the expense structure belongs beside every figure in a comparison.

How a concession moves the number in apartment leases and market series

Apartment leases make the arithmetic plain. A unit listed at $2,000 monthly with one free month on a 12-month lease yields $22,000 for the year against $24,000 at face.

A one-year term puts the concession over a short base, so a single free month moves the annual figure noticeably. Multi-year commercial leases spread free rent across a longer base, which dilutes the effect per year while the dollars given up stay the same.

Market-level series use the same idea. In one multifamily market, effective rent growth averaged about 5% while new supply ran about 5% of existing inventory, a pairing read as deliveries being absorbed. A series like that is only as comparable as the definition behind it, and it describes one period in one metro.

Worked example: two five-year office leases with different concession packages

Both cases are hypothetical and use the same space, the same five-year term and the same basis, which is net effective rent per square foot per year after free rent and a tenant improvement allowance. Escalations and commissions are left out so that only the two concessions change the result.

Case A has a face rent of $30 per square foot per year, five months of free rent and an allowance of $40 per square foot. Monthly face rent is $30 divided by 12, or $2.50. Face rent over five years is $30 multiplied by 5, or $150. Five free months cost $2.50 multiplied by 5, or $12.50, so collections are $150 minus $12.50, or $137.50. Before the allowance, that averages $137.50 divided by 5, or $27.50 per year. Subtracting the $40 allowance leaves $97.50, and $97.50 divided by 5 gives a net effective rent of $19.50.

Case B has a higher face rent of $33, ten months of free rent and an allowance of $60. Monthly face rent is $33 divided by 12, or $2.75. Face rent over five years is $33 multiplied by 5, or $165. Ten free months cost $2.75 multiplied by 10, or $27.50, so collections are $165 minus $27.50, or $137.50. Before the allowance that is again $27.50 per year. Subtracting the $60 allowance leaves $77.50, and $77.50 divided by 5 gives a net effective rent of $15.50.

Face rent in Case B sits $3 above Case A, yet net effective rent in Case B sits $4 below it. The two cases collect the same $137.50 before the allowance, so the entire gap comes from the larger allowance in Case B. A comparison that stopped at face rent, or at free rent alone, would rank them the wrong way round.

Effective rent, the rent roll and what the property collects

Effective rent is a lease-level calculation. Collected income is what the property received, and a review of trailing income and expenses beside net effective rent can show an asset generating less income than its rent roll suggests, because concessions and discounts sit between the two.

Lenders test collections directly. In agency multifamily underwriting, when trailing three-month net rental income falls more than 2% below the trailing six-month or twelve-month figure, a downward adjustment of at least 2% is required. A rent roll that looks full at scheduled rents can still produce a lower underwritten income once recent collections are measured.

Rent roll timing matters too. An appraisal checklist for agency multifamily loans asks that the rent roll be dated within 30 days before the effective date of value, so scheduled rents reflect current leases. That tightens the schedule but still leaves the question of what was collected against it.

Comparable leases that leave out the concession package

Lease comparables can omit free rent and tenant improvement details. A comp listing only a face rate and a term gives no way to compute an effective rent for it.

The same gap exists on the sale side, where an investment sale comp may omit the cap rate and the lease terms behind the price. In both cases the terms that explain the visible number sit outside the record.

Common mistakes in effective rent comparisons

Setting a face rent from one lease against an effective rent from another mixes two measures. In the example, Case B looks $3 higher on face rent and ends $4 lower on a net effective basis.

Leaving the period unstated makes the figure unreadable. Free months and escalations fall at different points in a term, and the average depends on the span over which they are spread.

Treating effective rent as collected income confuses a lease calculation with realized results. Collections can fall short of the rent roll, and a trailing income and expense review is what shows the difference.

Comparing figures built on different inclusions also misleads. Where one calculation counts broker commissions and another does not, the two outputs measure different things even for identical leases.

Stopping at free rent ignores allowances. In the example, both cases collect $137.50 before the allowance, so the entire difference in net effective rent comes from that single line.

Checklist of questions for reading an effective rent figure

What period does the figure cover? Free rent and escalations produce different averages over different spans.

Is the figure net or gross of operating expenses? A net lease places the tenant’s share of expenses on top of rent, so the expense structure changes what the rent line means.

Which concessions are reflected? Free rent and discounts each lower the yield of a lease relative to face rent.

Are escalations included? Later-year increases raise the average above the starting rate and can offset part of a concession.

Does the method count broker commissions? Local practice differs, and the answer changes the result.

Does the comparison use the same inclusions on every lease? Different treatment of allowances or commissions makes two figures incomparable.

What do trailing collections show beside the rent roll? Actual income and expenses reveal whether scheduled rents were realized.

Do the comparables disclose free rent and allowance terms? A comp without them cannot be converted to an effective rent.

How recent is the rent roll behind the figure? A lender checklist can specify a window of 30 days before the effective date of value.
