3.3 Market Delineation and Market Conditions

Market Analysis Is Not Optional Color Commentary

AQB Content Area I.f requires market analysis: market delineation (neighborhood, linkages), market conditions (supply and demand, absorption, capture rates), and types of market analysis. On the National Exam, market analysis supports highest and best use, the credibility of comparable selection, time adjustments, vacancy and rent conclusions, and feasibility. A value opinion that skips the competitive market is guesswork dressed as a form.

Market Delineation: Area, Neighborhood, District

Market delineation answers: With which properties does the subject compete? The competitive set is defined by substitutability — what a typical buyer would consider instead of the subject — not by a fixed radius drawn on a map for convenience alone.

A subject house may sit in a named subdivision (neighborhood), compete with similar houses across three adjacent subdivisions (market area), and draw employment demand from a metro (region). A bulk warehouse may compete across an entire industrial district even when residential neighborhoods nearby are irrelevant.

Steps in Delineation (Practical Sequence)

1. Identify the property type and most probable user (owner-occupant, investor, both).
2. Identify substitutes buyers actually consider (size, age, quality, use, price band).
3. Map physical and man-made barriers (highways, rivers, school-boundary lines, industrial edges).
4. Identify linkages to demand generators.
5. Test the area with sales and listing search — if you cannot find competitors inside your drawn boundary, the boundary is wrong.

Linkages

Linkages are the time and cost relationships between a property and the places people or goods need to reach. Examples:

• Commute time to major employment centers
• Distance to schools, groceries, healthcare, and recreation
• Access to freeways, rail, ports, or transit
• For commercial property: drive-time trade areas, rooftops, and traffic counts

Strong linkages support demand and value; broken linkages (a new bypass that removes drive-by traffic, a bridge closure) can create external obsolescence. When exam items mention a new employer campus 12 minutes away or a highway that splits a subdivision from schools, they are testing linkage thinking inside market delineation.

Market Conditions: Supply, Demand, and Balance

After you know where the market is, measure how it is performing as of the date of value.

Buyer's Market vs Seller's Market

A balanced market sits between extremes: marketing times near local norms, neither side consistently dictating terms. Always use local norms; a "six-month supply" rule of thumb is a teaching device, not a national law.

Worked Example: Months of Inventory

Months of inventory (also called months of supply) estimates how long it would take to sell existing active listings at the recent sales pace:

$$\text{Months of inventory} = \frac{\text{Active listings}}{\text{Sales per month}}$$

Data for a residential market area (as of date of value):

• Active competitive listings: 84
• Closed sales in the last 6 months: 72

Step 1 — Sales per month

$$72 \div 6 = 12 \text{ sales per month}$$

Step 2 — Months of inventory

$$84 \div 12 = 7.0 \text{ months}$$

Interpretation: At the recent pace, current listings represent about seven months of supply. Relative to a common balanced band of roughly 4–6 months, this leans toward a buyer's market (more supply than the recent absorption rate clears quickly). The appraiser should look for longer DOM, more concessions, and possible downward market-conditions adjustments if the trend is confirmed by price indices and listing-to-sale ratios — not by the single ratio alone.

Variant check: If active listings fall to 48 while sales stay at 12 per month, inventory is 4.0 months — nearer balance or a mild seller's market depending on local benchmarks and trend direction.

Absorption and Capture Rates

Absorption measures how much space or how many units the market takes down over time (for example, 40 apartment units absorbed per quarter, or 25,000 SF of industrial leased in a year).

Net absorption usually means change in occupied stock (move-ins minus move-outs). Gross absorption counts new leases without netting vacates. Know which definition a data source uses.

Capture rate is the share of total market demand a subject or proposed project is expected to attract:

$$\text{Capture rate} = \frac{\text{Subject demand (units or SF)}}{\text{Total relevant market demand}}$$

Example: Fundamental analysis shows demand for 200 new multifamily units over the next year in the delineated market. A proposed 60-unit project that underwrites 30 units of first-year absorption implies a capture rate of 30 / 200 = 15%. The exam question is whether 15% is reasonable given competitive projects, location, and product quality — not whether the arithmetic is hard.

Capture rates that are optimistically high are a common feasibility failure: the project assumes it will steal more demand than competition will allow.

Types of Market Analysis

Inferred analysis asks: What do recent transactions and listings imply about balance today? Fundamental analysis asks: How many households (or firms) will need this property type, how much competitive supply exists or is planned, and what residual demand remains for the subject?

Both types can support highest and best use. A simple inferred conclusion ("seller's market, values rising 0.5% per month") may suffice for a straightforward house. A proposed 200-lot subdivision usually needs fundamental demand and absorption support.

Levels of Market Analysis (Conceptual)

Appraisers sometimes describe market studies by intensity (general market study vs detailed marketability study for the subject). For exam purposes, remember the chain:

1. Market study — demand and supply for a property type in an area
2. Marketability study — how a specific property or project competes and absorbs within that market
3. Feasibility — whether a use is financially viable given costs, value, and risk (bridges into investment analysis and HBU)

Putting Delineation and Conditions into the Appraisal Process

Exam Traps for Market Analysis

1. Drawing a one-mile radius and calling it delineation without testing substitutability.
2. Confusing neighborhood with district (mixed complementary uses vs single-use concentration).
3. Using active listings alone as "demand." Listings are supply; sales and leasing are better demand evidence.
4. Miscomputing months of inventory (forgetting to convert multi-month sales to a monthly rate).
5. Assuming a national "6 months = balanced" rule always applies without local context.
6. Setting capture rates without competitive inventory — arithmetic without marketability.
7. Treating inferred and fundamental analysis as enemies. They are tools at different intensity; both are valid when appropriate to the problem.

Market delineation and conditions analysis turn PETE-era legal constraints and date-of-value premises into a living picture of competition. The next section adds the investment math that often supports feasibility and the income side of that picture.
