An Owner's View of the Commercial Appraisal
If you own an office building, a strip center, a warehouse or a parcel of commercial land in the Houston area, sooner or later someone is going to ask what it is worth, and they are going to want the answer in writing. A commercial real estate appraisal is that written answer: an independent, credentialed opinion of market value, prepared under professional standards, that a lender, a court, a tax authority or a partner can rely on.
Stacy Sherman, Broker works both residential and commercial property from her Kingwood office, which is rare in the Lake Houston area, and a lot of her commercial conversations start right here: an owner who has a loan maturing, a partner who wants out, an estate to settle or a property tax bill that looks too high. This guide explains how appraisers arrive at a number, who orders an appraisal and why, and how it differs from a broker opinion of value.
Why Commercial Appraisals Work Differently
A commercial property is valued mostly as an investment. A house is priced largely by what similar homes nearby sold for; a leased commercial building is priced largely by the income it produces and the risk attached to that income. That is why two buildings of the same size on the same road in Humble or Kingwood can carry very different values: one may be fully leased to a creditworthy tenant on a long lease, while the other sits half empty with leases rolling next year.
Understanding what drives the appraiser’s conclusion helps you gather the right records and spot an error before it costs you money.
The Three Approaches to Value
The income approach
This is usually the primary method for leased commercial property. The appraiser estimates net operating income (NOI), which is the property's effective gross income minus operating expenses, before debt service and income taxes. That NOI is then converted to value, either by direct capitalization (NOI divided by a market capitalization rate) or by a discounted cash flow analysis that projects income over a holding period and discounts it back to today. Vacancy, lease terms and tenant quality all flow through it.
The sales comparison approach
Here the appraiser studies recent sales of similar properties and adjusts for differences in size, location, age, condition, occupancy and the date of sale. For owner-occupied buildings and vacant commercial land, sales data often carries more weight than income. In thinner submarkets, finding truly comparable sales is one of the hardest parts of the job.
The cost approach
The appraiser estimates what it would cost to replace the improvements today, subtracts depreciation (physical wear, functional obsolescence and external factors), and adds the land value. It matters most for newer buildings and special-purpose property such as a church or school.
Most commercial reports develop more than one approach and then reconcile them, explaining which one the appraiser weighted most and why. Reading that reconciliation section closely is the quickest way to understand your number.
Cap Rates and NOI: The Numbers Behind the Number
Because the income approach drives so many commercial appraisals, two terms come up in almost every conversation: NOI and the capitalization rate. The cap rate is simply NOI divided by value, so a lower cap rate means a higher value for the same income. The appraiser supports the rate with market sales and the property’s risk profile, including tenant credit and remaining lease term. Our guide to cap rates for Houston commercial real estate walks through the math and what pushes a rate up or down.
For an owner, the practical lesson is that small changes in NOI or in the cap rate move value a lot. Documenting every recoverable expense, showing which leases have been renewed, and explaining any one-time costs in the operating history can all change how the appraiser reads your income.
Who Orders a Commercial Appraisal, and Why
The reason shapes the report: an estate may need value as of the date of death, while a tax protest looks at value as of January 1. If you are fighting an assessment, start with our Houston commercial property tax protest guide so the appraisal answers the question the review board will ask.
Credentials: Certified General Appraisers and the MAI
Commercial appraisers in Texas are licensed by the Texas Appraiser Licensing and Certification Board (TALCB). A certified general appraiser may appraise all types of real property without regard to complexity or transaction value, which is why lenders generally look for that credential on commercial assignments.
Many owners also ask for an MAI. The MAI is a professional designation awarded by the Appraisal Institute to valuation professionals who meet its education and experience requirements and agree to its Code of Professional Ethics and Standards of Professional Practice. It covers commercial, industrial, agricultural, residential and land valuation. You can confirm a designation through the Appraisal Institute’s Find an Appraiser directory, and confirm a Texas license through TALCB. Ask, too, about local experience with your property type.
8 Documents Owners Should Gather Before the Appraisal
A current rent roll
Every tenant, suite size, lease start and end date, base rent, escalations, security deposits and any free rent or concessions still running.
A trailing 12-month operating statement (T-12)
Income and expenses for the last twelve months, ideally by month. Flag one-time repairs so they are not read as recurring costs.
Copies of every lease and amendment
The appraiser needs to know who pays taxes, insurance and common area maintenance, whether leases are NNN, gross or modified gross.
Property tax statements and the current appraisal district notice
These show the tax burden a buyer inherits and help reconcile expenses.
A survey, site plan and building plans
Accurate land area, building area and parking counts prevent avoidable errors.
A capital improvement list
Roofs, HVAC units, parking lot work and tenant finish-out with dates and costs.
Environmental and inspection reports
Any Phase I environmental site assessment, property condition report or engineering study you already have.
Anything unusual
Deed restrictions, easements, pending litigation, a tenant in default, flood history or a planned road project.
How Long Does a Commercial Appraisal Take?
Timing depends on property type, complexity and how busy local commercial appraisers are, so ask for a timeline when you request a fee quote rather than assuming one. The fastest way to keep an appraisal on schedule is to hand over a complete document package on day one and to make the property easy to inspect.
When a lender orders the report, the appraiser reports to the lender and you cannot pick the appraiser. When you order one yourself, for a tax protest, estate or buyout, you are the client.
Appraisal vs. BOV vs. Broker Pricing
Owners often ask whether they need a full appraisal or whether a broker can simply tell them what the building will sell for. They are different tools. A broker opinion of value (BOV) from Stacy Sherman, Broker answers a market question: if you put this building on the market, who buys it and what will they pay?
If a lender, court or tax authority needs a value, you need an appraisal. If you are deciding whether to sell, hold, lease up first or refinance, a BOV is often the faster and more practical first step. Our owner’s guide to selling commercial property in Houston picks up where the valuation leaves off and our sell vs hold decision guide helps frame the choice.
Selling? Your Next Purchase Starts Now
Here is the part of the conversation many owners do not plan for: most people who sell a commercial property are buying something next. If you plan to defer tax on the gain, the 1031 exchange rules for Texas commercial owners put hard deadlines on you: under IRS rules, replacement property must be identified within 45 days of the sale and received within 180 days or by your tax return due date, whichever comes first.
Because Stacy works both sides, she can help you value and sell what you own while lining up replacement investment property in Kingwood and Houston at the same time, and she can walk you through a commercial due diligence checklist before you commit to the next one.

Request a Broker Opinion of ValueCommercial Appraisal FAQs
What is a commercial real estate appraisal?
It is a written, independent opinion of the market value of a commercial property as of a specific date, prepared by a state licensed or certified appraiser under the Uniform Standards of Professional Appraisal Practice.
Which appraisal approach matters most for a leased building?
For income-producing property, the income approach usually carries the most weight, supported by the sales comparison approach. The cost approach tends to matter more for new or special-purpose buildings.
Can I choose the appraiser for my commercial loan?
No. For a bank loan, the lender engages and controls the appraiser. You can supply records and point out factual errors.
Is a broker opinion of value the same as an appraisal?
No. A BOV is a market analysis from a licensed broker and is not an appraisal. Stacy offers one through her BOV page.
Can an appraisal help with my property tax protest?
It can. An independent appraisal is one of the stronger forms of evidence at an appraisal review board hearing. Our commercial property tax protest guide covers deadlines and preparation.
