Every CAM reconciliation error that surfaces in the spring was a budget decision made in the fall. The pool roster, the cap rules, the gross-up method, the denominator and the build order all get set once, now, and then carried forward for a year. Here are the five settings to check before the 2027 budget and the estimate letters go out.
The CRE budget calendar is compressed at the end. Kevin Whalen of Cushman & Wakefield describes November as the month to “wrap up budgets, issue estimate letters for the following year,” and many management agreements set a submission date in early fall with a window after which the budget is deemed approved. That puts the last real chance to change a recovery setting somewhere in the next few weeks. Kardin keeps a sourced month-by-month CRE budget calendar if you want the whole year.
What makes recoveries different from the rest of the budget is that their output is a promise. An estimate letter tells each tenant what they will be billed every month next year. In the spring you compare that estimate with what they should have been billed once actuals are in, and the difference is the reconciliation. So the setup behind the estimate is not a draft that gets revisited; it is the baseline for a year of billing and for the reconciliation at the end of it. We wrote in September about where CAM reconciliation errors come from. This is the same list, moved upstream to the moment the decisions are made.
Every recoverable expense belongs to a pool, and every tenant who owes a share has to be assigned to it. When a tenant is missing, the pool total still allocates in full, so either everyone else pays slightly too much or the landlord absorbs the gap. Nothing flags it, because the math balances.
Budget season is where the roster goes wrong, and the usual cause is a renewal. When a tenant renews, the rent, tenant improvements and leasing commissions carry forward from the renewal assumption. The expense reimbursements do not, unless someone sets them up again. The renewed tenant sits on the rent roll paying rent, absent from every pool, and the estimate letter they receive in November is wrong by their whole share. Renewals get signed all year; this is the month to go down the rent roll and confirm that every renewal that landed since last budget season still has its recovery language attached.
Three smaller roster checks while you are there. A tenant that was renamed in place rather than expired and recreated carries a stale suite record, and the new lease terms may never have attached. A tenant whose recovery method changes mid-year needs two rent roll rows, because the lease dates drive the recovery language. And any expense account added during the year without a category will not calculate at all, which reads as a tenant paying nothing rather than as an error.
Controllable expense caps are the most expensive place to be wrong, because the error compounds for the life of the lease.
Three methodologies exist, and the lease decides which one applies. Cumulative and compounded, where the cap grows on last year’s cap, is the default assumption when the lease is silent. Cumulative but not compounded grows by a fixed dollar amount each year. Non-cumulative grows over the lesser of last year’s actual controllables or last year’s cap, which means it ratchets down whenever expenses come in under the cap, and they usually do. Kathy Lim, an institutional practitioner speaking at a BOMA session, put it plainly: “your caps are gonna be less and less and less every year.” If your budget assumes a cap that is not decaying when the lease says it should, the estimate is too high and the reconciliation refunds the difference.
The error that costs the most is carrying the original lease cap through a base year reset. When a base year resets, the lease is saying that year’s rent covers that year’s expenses, and the controllable cap resets from that year as well. Carry the old cap forward and you under-recover on every reconciliation for the remaining term.
“That’s wrong. You’re losing money for the landlord on that basis.”
Any renewal or extension signed this year that reset a base year needs its cap re-based before the 2027 estimate is built.
Two more things to settle now rather than in March. Carryover language, which lets unrecovered dollars above the cap be recaptured in a later year with headroom, is not standardized, and a building-wide assumption will be wrong on some leases. And a cap applies to accounts, so name the cap on every controllable account, including the ones that carried a zero last year. A new controllable account that starts spending in 2027 without a cap on it is uncapped, and nobody will notice until a tenant does.
Gross-ups adjust variable expenses to what they would have been at a stated occupancy, usually 95% occupied. Occupied, not leased; the lease language matters. The method is set per expense line at budget time and carries into the estimate, so a wrong method overstates or understates a pool for every tenant in the building for a year.
The most common mistake is a simple gross-up, cost divided by occupied square feet and extended to 95%, applied to utilities. Utilities have a fixed baseline load. At full vacancy the chillers, elevators, lobby and parking lot lighting still run. A simple method treats every dollar as variable, so electricity comes out overstated. The right approach applies a vacancy consumption rate, and that rate is a judgment call by building: 30 to 50% for general office electricity, lower with occupancy sensors and VAV boxes, higher with twenty-year-old HVAC in a hot climate. Water depends on what is using the water. An industrial property with a small office component and landscaped grounds runs 50 to 75%, because the water bill is an irrigation bill. A downtown office tower with no exterior landscaping might be 5 to 10%.
Two more worth deciding now. Post-pandemic rent rolls broke the management fee gross-up in many buildings: when old leases are at $30 a foot and new ones at $50, or a large tenant is burning off free rent, a blended rate understates the fee. The fix is to add back the fee you should have earned on the free rent, and it matters most when the tenant on free rent is more than 10% of the building. And some costs should not be grossed up at all. A day porter is a day porter whether the building is 60% or 95% occupied. The rule: do not gross up a cost you would not actually add as the building fills.
Pro rata share is a fraction, and the budget sets the bottom of it. The denominator deserves its own check because it changes for reasons that have nothing to do with expenses.
Leased square footage rarely equals measured square footage. Owners carry a phantom suite, often called a BOMA suite, to bridge the gap between rent roll square footage and building square footage, and load factors legitimately move year to year as tenants take or give back common area. If the rent roll changed shape this year, the denominator probably did too.
Directly metered tenants are the other denominator question. A ground-floor cafe on its own electric meter still owes a share of common-area consumption: the parking lot lighting, the lobby, the landscape irrigation. One practitioner’s worked split for a cafe was 20% of the house electric meter, 20% of gas and 45% of water. The same logic applies to space you do not clean. If a leased floor is dark, or a tenant handles its own janitorial, add back a synthetic cleaning cost for that space so the rest of the building pays a correct share of the contract rather than an inflated one. And watch for netting: if the water figure in the accounting system is already net of what a restaurant was billed back, add that amount back before allocating, or the office tenants underpay.
Retail is a different animal here. Office pools are essentially four fixed slots with one implicit denominator per tenant. Retail pools are unlimited charge codes with denominator groups, user-defined sets of suites drawn from lease language, and the pro rata share is a computed function of group membership that moves when suites move. A retail budget needs its groups checked whenever a suite changes hands, not just when expenses change.
A CRE budget has three components in a fixed order. Kardin co-founder Karen Schwartz describes it this way:
“There are really three major components of the budget. The first is gonna be that rental revenue. The second piece of it will be your expenses, your capital. And then the third piece is once the rent roll is in place and all of your expenses are in place, then you can set up all of the recoveries.”
Recoveries are downstream of both by construction. That has a practical consequence at budget lock: the recovery estimates are only right if they were built, or rebuilt, after the last change to the rent roll and the last change to the expense budget. A late renewal, a revised insurance line, an occupancy assumption that moved in the final review, any of those changes the recovery estimate, and in a spreadsheet nothing recalculates unless someone remembers. In a fifty-tab workbook touched by three people over four months, someone usually does not.
The same dependency is what makes the setup worth doing properly once. Set the pools, caps, gross-up methods and exclusions at budget time and they roll forward into the first-quarter reforecast and the year-end reconciliation with the actuals dropped in. As Karen puts it, “all of the adjustments that you’ve made, the caps, the exclusions, that’ll all be in place so you don’t have to do this again the second time.” Build them beside the budget instead of after it, and every one of those decisions gets made three times a year.
The last check is not a setting, it is an audit. Before the budget is locked, run a recoverable operating expense leakage report on the draft. It splits the gap between recoverable expenses and recovered expenses into its four sources: vacancy, base years, caps and free reimbursements. Some of that leakage is contractual and expected. The point of running it on a budget rather than on actuals is that an unexpected number at this stage is almost always a setup problem, not a market one.
Two heuristics, both from practitioners. Unexpectedly low CAM recovery usually means a schedule is not set up, which is Setting 1. An unexpectedly high cap adjustment usually means a keying error, an extra zero somewhere, which is Setting 2. In Kardin’s own demo portfolio, roughly half of recoverable expenses went unrecovered: $800,000 to vacancy, $674,000 to caps and about $300,000 net with no contractual reason. Found in October, the last of those is a correction. Found in March, it is a refund.
Software does not know what your lease says. It will not pick the cap methodology, grow a cap for you, decide a vacancy consumption rate, or tell you whether a renewal carried its reimbursements. What a purpose-built tool does is keep each of those decisions attached to the tenant and the pool, so that a setting made in October is still in force the following March, and so that a late change to the rent roll reaches the recovery estimate without anyone having to remember.
If your 2027 recovery estimates are about to go out from a spreadsheet that was built in a different order, see how Kardin handles recoveries, or ask us to walk through your setup before the estimate letters are printed. Kardin works alongside Yardi, MRI, RealPage and other accounting systems rather than replacing them; the estimates and the reconciliation export back to your system for billing.
Before the budget is locked and the estimate letters are issued, which for calendar-year operators is typically November. The estimates in those letters are what the following year’s reconciliation compares against, so the pools, caps, gross-up methods and denominators behind them become the baseline for twelve months of billing.
Carrying a controllable expense cap through a base year reset. When a base year resets, the cap resets from that year as well. Carrying the original lease cap forward under-recovers on every subsequent reconciliation for the remaining lease term, and the error compounds.
When a tenant renews, rent, tenant improvements and leasing commissions usually carry forward from the renewal assumption, but expense reimbursements do not unless they are set up again. The renewed tenant pays rent and sits outside every recovery pool. The damage appears at reconciliation the following spring.
Any cost you would not actually add as the building fills. A day porter is the standard example: the same person absorbs the work at 60% or 95% occupancy. Gross-ups belong on expenses that actually move with occupancy, such as electricity, nighttime janitorial and management fees, and even then the method matters. A simple gross-up on utilities ignores the fixed baseline load and overstates the pool.
No, and it should not, because it cannot read the lease. What a purpose-built tool can do is hold the methodology you chose against the tenant and the pool, apply it consistently to the estimate, the reforecast and the reconciliation, and flag leakage by source so a setup error is visible before the estimate letters go out.
