Cap Rates, NOI, and What Drives Commercial Value

Every commercial building in Kansas City has a price. That price is not pulled from the sky — it is the output of a two-variable equation that any owner can run on the back of a napkin. The trouble is most owners only see one side of it. They watch rents and assume the building goes up with them. Then a buyer's underwriter applies a cap rate and the offer comes in a million dollars below what the owner expected. Cap rate moved. NOI didn't move enough to cover it. Welcome to commercial real estate. This article walks the math, the inputs, and the things you can actually do about it as an owner-operator — without needing a CFA or an Excel model with macros.

Commercial value is income capitalized. Take the building's net operating income (NOI) for a year and divide by the market cap rate for that asset class, and you get value. That's it. A 40,000 SF Class B industrial building throwing off $400,000 of NOI, in a market trading at a 7.5% cap, is worth $400,000 ÷ 0.075 = roughly $5.33M. Drop the cap to 6.5% and the same NOI prints $6.15M. Push NOI to $450,000 at the same 7.5% cap and you're at $6.0M. Two levers, multiplicative. Most owners obsess over the top line and ignore both. Brokers who only quote price-per-square-foot are doing you a disservice — PSF is a sanity check, not a valuation. Income is.

NOI is gross revenue minus operating expenses — and nothing else. Start with scheduled gross rent, add tenant reimbursements (CAM, taxes, insurance pass-throughs in NNN deals), and that's effective gross revenue. Subtract a vacancy and credit loss reserve (typically 5-10% depending on asset class and tenancy). Then subtract operating expenses: property taxes, insurance, common area maintenance, management fees (3-5% of revenue is standard), repairs and maintenance, utilities not reimbursed, landscaping, snow. What's left is NOI. What is NOT in NOI: debt service, capital expenditures, leasing commissions, tenant improvements, depreciation, owner's income taxes. Those all matter for cash flow — they do not matter for valuation. A building's NOI is the same whether it has a 70% LTV loan at 7.5% or zero debt. That's the point. Cap rate values the asset, not the capital stack.

Cap rates are a yield. They reflect what an investor demands to take on the risk of owning that specific income stream. Four things move them. First, the 10-year Treasury — the risk-free rate sets the floor; when the 10Y rips from 3.5% to 4.5%, every cap rate in the country expands 50-100 bps within a quarter. Second, lender appetite — when banks pull back from a sector (office in 2024, retail in 2020), buyers need higher going-in yields to make the math work. Third, asset class risk — industrial is structurally tightest because demand is durable and operating intensity is low; multifamily next; office and retail wider because of tenant turnover, capex, and obsolescence risk; land is highest because it produces no income. Fourth, deal-specific factors — tenant credit (national NNN tenant vs local LLC), weighted average lease term remaining (a building with 8 years left on a Walgreens lease trades 150 bps tighter than the same box with 18 months), location, and physical condition.

You don't control the 10-year Treasury. You do control most of what's left. Five levers, ranked by impact. (1) Raise NOI by raising rents — sign new leases at market, bake in 3% annual escalations, push expense reimbursements to full NNN where the market allows. A $1/SF rent bump on 40,000 SF is $40,000 of NOI, worth $533K at a 7.5% cap. (2) Raise NOI by reducing opex — re-bid insurance every renewal, protest property taxes (do this yearly, it's free money), LED retrofit the lights, audit the management fee. (3) Compress your cap rate by extending lease terms — a tenant with 4 years left who renews for 7 just bought you 50-100 bps of cap compression. (4) Improve tenant credit mix — replace a marginal local tenant with a regional or national credit at the next renewal, even at flat rent. (5) Strategic capex — modernized lobby, new HVAC, repaved parking. These reduce perceived risk and capex liability for the next buyer, which compresses cap. None of these is fast. All of them compound.

Where Kansas City is trading in mid-2026, rough ranges by asset class. Class A industrial: 5.75-6.75%, with stabilized Class A bulk near the bottom of the range. Class B industrial: 6.75-7.75%, infill flex slightly tighter. Class A multifamily: 5.25-6.25%, newer urban core product the tightest. Class B multifamily: 6.5-7.5%, value-add deals wider. Class A office: 7.5-9%, with quality suburban product and credit tenancy at the low end. Class B office: 9-11% and a thin buyer pool — the bid-ask spread is real. NNN retail (single-tenant credit): 6-7.25%, depending on lease term and brand. Strip retail (multi-tenant): 7.5-9%. Medical office: 6.5-8%, with hospital-affiliated buildings tighter. These move week to week with the 10Y. Treat them as a starting point for a conversation, not a quote. And don't confuse going-in cap with stabilized cap on a value-add deal — they're different numbers solving different problems.
