Commercial property owner questions: income, costs and decisions

Start with the question you need to answer, then use the detailed guide and official source. These owner resources emphasize 10,000-100,000-SF industrial buildings in the nine Illinois counties while covering financial questions shared by many commercial properties.

Educational, not an appraisal or investment, tax, legal, engineering or insurance advice. Verify your property, leases and current rules with qualified advisers.

Income, value and cash-flow questions

NOI: definition, inclusions, recoveries and worked statement explains operating income. DCF: projections, present value and exit sensitivity follows that income through a hold. Investment diligence and calculators connects it to price and debt.

Operating costs, insurance and tax questions

Use cost controls for energy, maintenance and CAM; owner insurance for limits, valuation and renewal questions; and Illinois property taxes for assessment, appeals and Cook incentive classes. Budgets, reserves and capital separates cash needs from accounting and tax treatment.

Prepare the next owner decision

Before renewing a lease, refinancing or selling, collect a current rent roll and lease abstracts, trailing statements, arrears, tax notices, policy schedules, contracts, condition reports and a capital plan. Model an operating downside before committing to a value or payout. Use the lease guide, selling guide and due-diligence checklist for the transaction itself.

Cook, DeKalb, DuPage, Grundy, Kane, Kendall, Lake, McHenry and Will have different local records and calendars. Use the county research directory to identify the correct authority; a Chicago address label does not establish jurisdiction.

Owner questions and answers

How is NOI calculated for commercial real estate?

Subtract vacancy and credit loss from potential rent, add collectible recoveries and other property income to get EGI, then subtract property operating expenses. Keep debt, depreciation and major capital cash needs separate. Read the detailed guide.

What is a good NOI?

There is no universal dollar amount or margin. Compare the same period, property use, lease structure, occupancy, condition and reserve convention, with evidence for future changes. Read the detailed guide.

What is included in operating expenses?

Real estate taxes, property insurance, owner-paid utilities, recurring repairs, maintenance and management are common categories. Recoveries and exclusions depend on leases; capital and financing are separate. Read the detailed guide.

How can I lower commercial property taxes in Illinois?

Check parcel characteristics and assessment evidence, then use the correct assessor or Board of Review process within its calendar. Evaluate PTAB or court review with counsel after county review. An assessment reduction is not a guaranteed proportional bill reduction. Read the detailed guide.

How can I reduce CAM charges?

Remove waste, compare equivalent vendor scopes, verify invoices and allocate only lease-permitted costs. Review caps, exclusions, audit rights and reconciliation timing instead of shifting disputed costs to tenants. Read the detailed guide.

How can I lower commercial building insurance costs?

Document risk improvements and accurate values, compare equivalent quotes and review deductibles with a licensed adviser. A cheaper premium is not a saving if it removes required or important protection. Read the detailed guide.

When should I use DCF instead of just a cap rate?

DCF is useful when lease rollover, capital spending or changing income matters during the hold. Direct capitalization is a one-year snapshot. Both require supported inputs and a consistent cash-flow basis. Read the detailed guide.

How can I increase commercial property value?

Improve durable collected income, accurate recoveries, building condition and leasing certainty while controlling waste. The value effect depends on risk, future costs and supported pricing assumptions; no fixed uplift is guaranteed. Read the detailed guide.

When should I sell an industrial building?

Compare holding, refinancing and selling after reviewing lease expirations, capital needs, debt maturity, tax basis and your liquidity/goals. Prepare the document file and review tax planning before committing to a sale. Read the detailed guide.

How much should I reserve for repairs and vacancy?

Build a property-specific schedule of capital work, leasing costs, deductibles, carrying costs and debt maturity. Separate restricted lender reserves from usable cash; no universal percentage guarantees adequacy. Read the detailed guide.

Does a triple-net lease eliminate owner expenses?

No. Contract exclusions, caps, vacancy, owner obligations and uncollected reimbursements can leave costs with the landlord. Read the signed lease rather than relying on the NNN label. Read the detailed guide.

What are DSCR, LTV and debt yield?

DSCR compares defined income to debt service; LTV compares debt to a lender's value basis; debt yield compares a defined NOI to loan balance. Lenders set their own conventions and requirements. Read the detailed guide.

Is a repair an expense or a capital improvement?

The scope and accounting/tax rules control. Routine maintenance and major replacements often have different treatment; IRS improvement rules examine betterments, restorations and adaptations. Ask a CPA rather than classifying solely by invoice size. Read the detailed guide.

Can a 1031 exchange remove all taxes from a sale?

No. A qualifying exchange can defer eligible gain; cash, nonqualifying property, ownership and timing issues may create tax. Consult a CPA, attorney and qualified intermediary before closing. Read the detailed guide.

Are ComEd and Nicor savings programs available to every building?

No. Utility territory/account, project type, equipment, program funding and application conditions matter. Check the official utility program before purchase; incentives and savings are not guaranteed. Read the detailed guide.
