How to budget expenses, reserves and capital for a commercial building
A profitable operating statement does not guarantee enough cash for a roof, a vacant suite or a loan maturity. A useful owner budget connects monthly operations, tenant recoveries, capital timing and financing without mixing them together.
What belongs in a commercial operating budget?
Start with actual invoices, signed leases and a monthly trailing operating statement. Budget base rent, recoveries, collection loss and ancillary income by tenant. For expenses, track property taxes, insurance, utilities, repairs, snow, waste, grounds, management and other recurring services. Place each renewal or seasonal bill in the month cash is due, while retaining an annual comparison.
For Chicagoland industrial assets, review winter service and heat, roof/drain condition, loading equipment and paving alongside the tenancy. Separate tenant-paid utilities from landlord service. Carry tax notices, appeal status and insurance-renewal assumptions into the budget rather than extrapolating one quiet year.
Each month compare budget to actual, explain price versus usage versus timing variances, update collections and forecast the remaining year. A tax refund or insurance recovery is not recurring annual income. The NOI reconciliation preserves the operating basis; a cash forecast shows when liquidity is needed.
How do I benchmark operating expenses without misleading comparisons?
State whether cost per square foot uses rentable, occupied or gross building area. Compare property type, heated area, tenant use, service level, reporting period and gross/net lease basis. Separate capital outlays and one-time events. Utility consumption per operating hour or occupied area can be more revealing than dollars alone.
Use your own normalized history, comparable vendor scopes and verified peer data when available. This guide supplies no Chicago expense ratios or market rates. A low expense ratio can reflect deferred maintenance, tenant-paid costs or missing management fees rather than efficiency. Label every data source and adjustment.
Capex versus opex: where do roof and HVAC costs go?
| Item | Owner cash / underwriting view | Review needed |
|---|---|---|
| Routine servicing | Typically recurring operating expense | Lease responsibility and accounting policy |
| Major roof/system replacement | Separate capital plan and cash outlay | Condition, scope, permits and CPA classification |
| TI and leasing commission | Leasing cash needs below ordinary NOI | Lease timing, amortization and tax treatment |
| Reserve deposit | Cash earmarked for future needs, not the repair itself | Lender convention, funding and access restrictions |
For federal taxes, IRS tangible-property rules distinguish ordinary expenses from amounts that must be capitalized, including betterments, restorations and adaptations. Dollar size alone does not settle that question. Safe harbors and elections have conditions; an owner should not relabel improvements as repairs just to reduce NOI or taxable income.
How much reserve cash does a commercial owner need?
There is no universal percentage that makes a reserve adequate. Prepare an asset schedule with condition, expected timing, installed replacement cost supported by estimates, responsibility under leases and contingency. Add vacancy carrying costs, TI/LC, deductibles, tax timing and loan maturity needs. Separate lender-restricted reserves from unrestricted cash you can use promptly.
Illustrative arithmetic, not a reserve recommendation: if a supported future project estimate is $120,000, existing dedicated funds are $20,000 and the project is five years away, a straight-line funding target is $20,000 per year before inflation, interest or contingencies. A sooner failure would require more cash sooner. Do not treat the annual reserve contribution and the eventual project as two expenses in the same cash-flow model.
Depreciation, cost segregation and 1031: what should I ask my CPA?
Depreciation allocates eligible capital basis over the applicable recovery period; it is not cash spent that year and is excluded from ordinary property NOI. Land is not depreciable. Basis allocation, placed-in-service dates, property classification, elections and current law matter. Start with IRS Publication 946 rather than a promised deduction.
A cost-segregation study identifies supported components and their tax classifications/recovery periods; it is not an automatic percentage write-off or a new operating expense. Ask about study quality, basis reconciliation, timing rules, costs and potential recapture on sale. The IRS audit-guide directory links its Cost Segregation guide and explicitly cautions that law may change after publication.
Section 1031 can defer recognition of qualifying gain on business/investment real-property exchanges, not erase it. Property held primarily for sale does not qualify; cash or other non-like-kind property can create taxable gain. Discuss ownership, qualified-intermediary arrangements, identification and completion timing, debt and state taxes before closing. See sale/1031 preparation and the IRS real-estate exchange overview. Consult a CPA and attorney; no tax result is promised.
Refinancing and debt costs belong in the liquidity plan
Track interest, amortization, fees, escrows, covenants, maturity, recourse and prepayment provisions. DSCR compares the lender's income measure to debt service; LTV compares debt to its value basis; debt yield compares a defined NOI to loan balance. There is no universal qualifying threshold here.
A balloon balance does not disappear because refinancing is planned. Test lower proceeds, higher borrowing cost and a delayed closing, and calculate the cash gap after payoff and fees. Use the existing debt-service calculator and financing guide and levered versus unlevered projections rather than a second duplicate calculator.
Owner questions and answers
What is included in commercial operating expenses?
Typically taxes, property insurance, owner-paid utilities, recurring repairs/services and management. Debt service, depreciation and major capital outlays are separate from ordinary NOI. State reserve and lease-recovery conventions.
Are reserves the same as capital spending?
No. A reserve earmarks cash; capital spending pays for work. A lender can treat reserves differently in underwriting, so reconcile the convention and avoid double-counting.
Does cost segregation increase NOI?
No. It concerns tax depreciation timing and classification, not rental operating income. Review eligibility, study quality, current law and later recapture with a CPA.
