What is the difference between a CMA, a BPO, and an appraisal?

A CMA is a comparative market analysis prepared by a real estate license holder to help a client price a property. A broker price opinion is similar but is usually requested by a lender or institutional client. An appraisal is a formal, USPAP-compliant valuation by a licensed or certified appraiser, and appraisal law or lending rules require one in many transactions — especially federally related transactions, unless an exemption or evaluation rule applies. Under Texas Occupations Code §1103.004, a real estate license holder may give a written price opinion (such as a CMA or BPO) in the ordinary course of business, but must not call it an appraisal or hold themselves out as an appraiser unless they hold that credential.

What is the capitalization rate formula?

Cap rate equals net operating income divided by value (or sale price). Rearranged, value equals NOI divided by cap rate. The cap rate reflects the risk and required return for that property type and market — higher cap rates generally indicate higher perceived risk or lower expected appreciation. The exam tests both directions of the formula: given two of the three (value, NOI, cap rate), you should be able to solve for the third without hesitation.

How is the gross rent multiplier (GRM) used?

GRM equals sale price divided by monthly gross rent (or annual gross rent — be consistent). It is a quick, rough screening tool, most useful for small residential income properties where comparable rental data is available. It does not account for expenses, so it is less precise than the cap rate. The exam may test the calculation in either direction (given GRM and rent, compute price; or given price and rent, compute GRM).

What are the three types of depreciation in the cost approach?

Physical deterioration (wear and tear), functional obsolescence (outdated design or features), and external or economic obsolescence (negative influences outside the property, like a freeway being built nearby). Each is estimated separately and subtracted from replacement cost new. Physical and functional obsolescence can sometimes be cured by repairs or renovations; external obsolescence is generally incurable because the cause is outside the owner's control.

Texas Real Estate Property Valuation — Study Guides & Practice Questions

Texas Real Estate Property Valuation

The valuation module tests how license holders estimate market value — the three classical approaches an appraiser uses, the comparative market analysis (CMA) a license holder prepares, and the formulas that connect income, expenses, and value for an income-producing property. Real estate license holders are not appraisers unless separately licensed or certified as appraisers, and they should not call a CMA or BPO an appraisal. They must, however, understand the methodology well enough to prepare a defensible CMA, explain an appraisal to a client, and recognize when a property is mispriced relative to the market. The module is concept-heavy with relatively few formulas, so the main exam risk is confusing closely related ideas — value vs. price vs. cost, depreciation types, the three approaches — rather than running out of math to do.

Key Subtopics

The sales comparison approach — selecting and adjusting comparable sales. The most common approach for residential property; adjustments add or subtract value from the comparable to reflect differences from the subject property.
The cost approach — replacement cost new, less accrued depreciation, plus land value. Most useful for new construction, special-purpose properties, and any property where comparable sales are scarce.
The income approach — gross rent multiplier (GRM), net operating income (NOI), and capitalization rate. The primary approach for income-producing property; the cap rate formula (value = NOI ÷ cap rate) is the most-tested income-approach math.
The principle of reconciliation — choosing the approach that best fits the property type. The exam tests scenario questions where you must identify which approach an appraiser would weight most heavily for a given property type.
Comparative market analysis (CMA) vs. broker price opinion (BPO) vs. formal appraisal. The three differ in who prepares them, what they are used for, and what credentialing is required.
Value vs. price vs. cost — why these three are not interchangeable. Value is what something is worth to a market participant; price is what was actually paid; cost is what it took to produce. The exam tests the distinctions with definitional questions.
Depreciation — physical, functional, and external (economic) obsolescence. Physical is wear and tear; functional is outdated design or features; external (economic) is negative influences outside the property.
Highest and best use — the four tests (legally permissible, physically possible, financially feasible, maximally productive). The Appraisal Institute definition is the canonical source, and the exam tests the order and substance of the four tests. The tests are applied sequentially: a use that fails any one test is eliminated before the next is considered, so legal permissibility (zoning, deed restrictions) is the first filter, and maximum productivity is the final tie-breaker among uses that pass all earlier tests.

Study This Cluster

Valuation does not have its own dedicated deep-dive articles yet — the cluster is built around the math and survey articles that overlap with it. The most efficient study path is to lock in the three approaches and the highest-and-best-use tests, drill the cap-rate math, and then test under timed conditions. Use the cluster articles for the math foundation, then practice the conceptual scenarios.

Area Calculations — square footage and lot-size math that feeds into every valuation method.
Commission Calculations — the math discipline that overlaps with the income approach.
Deeds and Title Transfer — title quality affects marketability and therefore value.
Survey & Legal Descriptions — accurate descriptions are the foundation of any valuation.
Property Valuation Practice Questions — timed practice with full explanations.

Bottom Line

Valuation is concept-heavy with relatively few formulas to memorize. The candidates who do well are the ones who can match the right approach to the property type, run a cap-rate calculation cleanly, and explain why a CMA is not an appraisal. The four highest-and-best-use tests and the three depreciation types are worth memorizing as ordered lists — they appear in scenario questions in that exact form.
