Now Is the Time to Clean Up Your Commercial Property Books for 2027.
With 2027 approaching, now is the time for commercial property owners to review and clean up their property management and accounting books.
Commercial property owners should enter the new year with accurate tenant balances, reconciled bank accounts, organized expenses, completed CAM reconciliations, verified rent increases, properly documented security deposits, and a realistic operating budget.
Waiting until tax season to address property accounting issues can create unnecessary stress and make it harder to understand how the property actually performed during the year.
Year end provides a natural opportunity to identify discrepancies, review tenant accounts, organize vendor expenses, confirm lease obligations, examine outstanding receivables, and make sure the financial records accurately reflect what happened during 2026.
Clean commercial property accounting books do much more than simplify tax preparation.
They help ownership make better decisions about leasing, maintenance, budgeting, refinancing, capital improvements, property management, and whether it may be time to sell or reposition an asset.
For owners who self manage commercial real estate, year end is also an ideal time to ask whether the current accounting system is still working effectively.
At McKee Commercial | The Herbert Group, we provide property level accounting as part of our commercial property management services and also assist owners who want professional accounting support while continuing to manage their properties themselves.
Why Is Year End the Best Time to Clean Up Commercial Property Books?
Year end gives ownership a clear stopping point to review financial performance before entering another operating year.
By the end of 2026, ownership should be able to answer important questions about the property without searching through multiple spreadsheets, bank statements, invoices, emails, and handwritten notes.
Owners should know:
• How much rent was collected
• Which tenants still owe money
• Whether every rent increase was implemented
• Whether vendor invoices were recorded properly
• Whether CAM expenses were categorized correctly
• Whether security deposit records are accurate
• Whether bank accounts reconcile
• Whether capital expenditures are clearly separated from routine operating expenses
• Whether there are old accounting entries that need to be corrected
• Whether the 2027 budget reflects the property's actual performance
If those questions are difficult to answer, the books likely need attention.
What Does It Mean to Have Clean Commercial Property Books?
Clean commercial property books are accurate, current, organized, and supported by documentation.
The accounting records should reflect what actually happened at the property.
Tenant payments should be applied correctly.
Vendor invoices should be categorized consistently.
Outstanding balances should be understandable.
Security deposits should match lease documentation.
Bank activity should reconcile with the accounting system.
Owners should not have to guess why a tenant shows a balance or why an expense appears in a certain category.
Good accounting should make the property easier to understand.
Why Clean Property Accounting Matters to Commercial Property Owners
Commercial real estate is an operating business.
Even a relatively small commercial property may involve multiple tenants, leases, vendors, maintenance expenses, insurance payments, taxes, security deposits, utility reimbursements, and CAM charges.
When accounting records are disorganized, ownership loses visibility.
That makes it harder to answer basic questions such as:
• Is the property performing better than last year?
• Are expenses increasing?
• Which tenants are behind on rent?
• Are operating expenses being recovered properly?
• Are all lease increases being implemented?
• Is the property generating the expected cash flow?
• Is the asset ready to refinance?
• Is the property ready to sell?
Clean accounting helps answer those questions.
Review Every Tenant Ledger Before 2027
Tenant ledgers are one of the most important parts of commercial property accounting.
Each tenant account should accurately show:
• Base rent
• CAM charges
• Utility charges
• Security deposits
• Late fees
• Credits
• Rent increases
• Additional rent
• Outstanding balances
• Other lease related charges
Year end is the right time to review every tenant ledger carefully.
If a tenant shows a balance, ownership should know exactly why.
An unpaid balance might represent legitimate delinquent rent, but it could also be caused by an accounting entry being applied incorrectly.
Old unexplained balances should not simply roll into another year.
Review Accounts Receivable Before the New Year
Clean books mean better visibility.
Commercial property owners should know exactly how much tenants owe before 2027 begins.
Accounts receivable should be reviewed by tenant and by age.
Owners should identify:
• Current balances
• Past due rent
• Unpaid CAM charges
• Utility reimbursements
• Payment plans
• Outstanding late fees
• Old tenant balances
• Unresolved credits
The longer an account remains unresolved, the more difficult it becomes to collect or explain later.
A clean year end receivable report provides ownership with a clear picture of what is collectible and what requires action.
Confirm All 2026 Rent Increases
Commercial leases frequently include scheduled increases.
Year end is an important time to verify that every 2026 rent increase was implemented correctly.
Missed rent increases can quietly reduce property income.
For a multi tenant property, several missed increases can materially affect annual revenue and NOI.
Ownership should also identify every scheduled increase for 2027.
Those increases should be tracked before the new year begins.
Why Lease Administration and Accounting Must Work Together
Commercial property accounting cannot be separated from lease administration.
The lease determines what the tenant should be charged.
The accounting system determines whether those charges are actually billed and collected.
Important provisions can include:
• Base rent increases
• CAM reimbursements
• Property tax reimbursements
• Insurance reimbursements
• Utility charges
• Administrative fees
• Security deposits
• Late fees
• Free rent
• Expense caps
• Base years
• Renewal terms
If accounting records do not reflect lease terms accurately, property income can be misstated.
Review Security Deposit Records
Security deposit records should also be reviewed before the end of the year.
Ownership should be able to identify the amount being held for every tenant.
That amount should match the lease and accounting records.
Security deposit records are particularly important when:
• A tenant moves out
• A lease is assigned
• Ownership changes
• A property is sold
• A new management company takes over
• Accounting systems are changed
Long term tenants may have deposits that have been carried for years.
Those amounts should still be clearly documented.
Reconcile Property Bank Accounts
Bank reconciliation is one of the most important controls in commercial property accounting.
The accounting records should match actual bank activity.
Any differences should be investigated.
Common reconciliation issues include:
• Outstanding checks
• Duplicate entries
• Missing deposits
• Incorrect payment amounts
• Unrecorded bank fees
• Vendor payments entered twice
• Tenant payments applied incorrectly
• Deposits recorded to the wrong property
Regular bank reconciliation helps identify issues before they become larger problems.
Review Accounts Payable and Vendor Expenses
Owners should also review unpaid invoices and vendor activity before closing out 2026.
Commercial properties typically generate expenses from many vendors.
These can include:
• HVAC contractors
• Plumbers
• Electricians
• Roofers
• Landscapers
• Janitorial companies
• Elevator contractors
• Security providers
• Parking lot contractors
• Pest control companies
• Fire and life safety vendors
• General contractors
Vendor invoices should be recorded consistently and supported by documentation.
Why Expense Classification Matters
Expense classification helps ownership understand where money is being spent.
If expenses are grouped inconsistently, it becomes difficult to compare one year to another.
Ownership should be able to identify whether increases are coming from:
• Utilities
• Property taxes
• Insurance
• Repairs
• HVAC
• Landscaping
• Janitorial services
• Security
• Management
• Capital projects
Consistent accounting improves financial visibility.
Separate Operating Expenses From Capital Improvements
Routine operating expenses and major capital improvements should not be mixed together without review.
Examples of capital projects may include:
• Roof replacement
• Major HVAC replacement
• Parking lot replacement
• Significant electrical upgrades
• Building renovations
• Major plumbing projects
• Exterior renovation
Proper classification helps ownership understand actual property operating performance.
Owners should also coordinate with their CPA or tax advisor regarding the tax treatment of capital expenditures.
Prepare for 2026 CAM Reconciliations
For many commercial property owners, CAM reconciliation is one of the most important year end accounting tasks.
CAM stands for common area maintenance.
Depending on the lease, tenants may reimburse ownership for certain operating expenses.
A CAM reconciliation compares estimated tenant payments with actual recoverable expenses.
Before preparing reconciliations, ownership should review:
• Recoverable expenses
• Nonrecoverable expenses
• Tenant pro rata shares
• Expense caps
• Base years
• Estimated CAM payments
• Administrative fees
• Property tax reimbursements
• Insurance reimbursements
The lease determines what can be billed.
The accounting records provide the supporting numbers.
Why Clean Books Matter for CAM Reconciliations
Poor accounting can create problems with CAM reconciliations.
If expenses are categorized incorrectly, ownership may fail to recover expenses that should have been reimbursed.
The opposite problem can also occur.
Tenants may be charged expenses that are not recoverable under the lease.
That can create disputes.
Clean books help ensure CAM reconciliations are accurate, supportable, and easier to explain.
Review Property Tax and Insurance Expenses
Property taxes and insurance can represent significant costs.
Year end is a good time to confirm that these expenses were recorded correctly.
Owners should also determine whether tenants were charged properly under their leases.
Projected 2027 increases should be included in the new operating budget.
Build a Realistic 2027 Property Budget
A commercial property budget should be based on actual performance.
Clean 2026 books provide the foundation.
Income projections may include:
• Contractual rent increases
• Lease renewals
• New leases
• Vacancy assumptions
• CAM reimbursements
• Utility reimbursements
• Other tenant charges
Expense projections may include:
• Property taxes
• Insurance
• Utilities
• Janitorial service
• Landscaping
• Repairs
• HVAC service
• Security
• Property management
• Capital improvements
• Other recurring expenses
A budget created from inaccurate records will not provide meaningful guidance.
Why Clean Books Improve Cash Flow Planning
Commercial properties often have large expenses that do not occur evenly throughout the year.
Upcoming obligations may include:
• Property tax payments
• Insurance renewals
• Roof repairs
• HVAC replacement
• Tenant improvements
• Leasing commissions
• Vacancy periods
• Major maintenance projects
Clean books and accurate budgeting help ownership prepare for those cash requirements.
Review 2027 Lease Expirations
Year end accounting should be connected to leasing.
Ownership should identify every lease expiring in 2027.
Upcoming expirations can affect:
• Rental income
• Vacancy assumptions
• Tenant improvement costs
• Leasing commissions
• Free rent
• Capital requirements
• Property value
Owners should understand which tenants are likely to renew and which may be considering relocation.
Why Clean Books Matter When Refinancing
Commercial property owners planning to refinance in 2027 should pay particular attention to financial records.
Lenders commonly request:
• Rent rolls
• Operating statements
• Lease documents
• Accounts receivable
• Occupancy information
• Property expenses
• Tax information
• Insurance information
• Historical income
Disorganized accounting can slow the process.
Clean books make it easier to provide lenders with reliable information.
Why Clean Books Matter When Selling a Commercial Property
Owners considering a sale in 2027 should also prepare their books in advance.
Potential buyers will carefully review financial performance.
They may request:
• Rent rolls
• Income statements
• Operating expenses
• Tenant ledgers
• CAM reconciliations
• Lease documents
• Security deposits
• Accounts receivable
• Vendor contracts
• Capital improvement history
• Maintenance records
A buyer wants confidence in the numbers.
Organized accounting can make a property easier to evaluate.
How Clean Accounting Can Help Support Property Value
Commercial property values are often closely tied to income.
If rental income is understated or expenses are not tracked properly, financial performance may not be presented accurately.
Clean accounting can help identify:
• Missed rent increases
• Uncollected reimbursements
• Excessive expenses
• Unnecessary vendor costs
• Delinquent accounts
• Incorrect billing
• Expense recovery opportunities
Improving these areas can strengthen financial performance and visibility.
Common Accounting Problems for Self Managing Property Owners
Self managing owners often handle accounting in addition to maintenance, tenant communication, leasing, and vendor coordination.
That can make it easy for accounting tasks to fall behind.
Common issues include:
• Mixing personal and property expenses
• Inconsistent expense categories
• Missing invoices
• Unreconciled bank accounts
• Inaccurate tenant balances
• Missed rent increases
• Incomplete CAM records
• Old receivables
• Poor security deposit tracking
• Missing lease information
• Inconsistent financial reporting
These problems do not necessarily mean the property is performing poorly.
They make it harder to know exactly how the property is performing.
When Should a Self Managing Owner Hire Professional Accounting Help?
A commercial property owner should consider professional accounting support when the financial side of the property becomes difficult to manage.
Warning signs include:
• Financial reports are difficult to produce
• Tenant balances are unclear
• CAM reconciliations are delayed
• Bank accounts are not regularly reconciled
• Rent increases are missed
• Vendor invoices are difficult to track
• Ownership does not know the true NOI
• Tax preparation requires extensive cleanup
• Multiple properties are becoming difficult to manage
Professional property level accounting can bring structure and consistency without requiring ownership to immediately turn over all management responsibilities.
What Is Property Level Accounting?
Property level accounting focuses specifically on the financial activity of an individual property.
It tracks the income and expenses associated with that asset.
This may include:
• Rent
• Tenant charges
• Vendor expenses
• CAM reimbursements
• Security deposits
• Accounts receivable
• Accounts payable
• Capital expenses
• Property taxes
• Insurance
• Utilities
• Financial reporting
For owners with multiple assets, property level accounting makes it easier to evaluate each property independently.
Can You Outsource Accounting Without Hiring a Full Service Property Manager?
Yes.
Some commercial property owners want professional accounting support but prefer to continue managing the property themselves.
This can be a good transition step.
The owner can continue handling operations while outsourcing accounting, reporting, and reconciliations.
At McKee Commercial | The Herbert Group, some owners begin with property level accounting services and later transition to full service property management.
That gives ownership an opportunity to experience our systems, reporting, communication, and understanding of the property before expanding the relationship.
How Professional Property Management Improves Accounting
Professional property management connects financial records with actual property operations.
The management team understands why an expense occurred.
It knows which tenant requested a service.
It understands what the lease requires.
It knows how the property is operating.
That operational knowledge can make financial reporting more meaningful.
At McKee Commercial | The Herbert Group, property management, accounting, and leasing are integrated.
That gives ownership a more complete view of property performance.
Why Integrated Property Management, Accounting, and Leasing Matter
Commercial property performance is interconnected.
Accounting affects leasing.
Leasing affects cash flow.
Maintenance affects tenant retention.
Tenant retention affects vacancy.
Vacancy affects property value.
When these functions work together, ownership receives a more complete picture of the asset.

Our focus is on office, retail, medical office, and light industrial properties.
