Valuation and Market Analysis on the NJ Real Estate Exam

The short answer: Valuation is 8% of the national portion of the NJ salesperson exam's content outline. It covers three things: appraisals (including when a licensed or certified appraiser is required), estimating value with the sales comparison, cost and income approaches, and comparative market analyses (PSI NJ Candidate Information Bulletin). Most questions come down to one skill: knowing which approach fits which property and how each one works.

This guide focuses on the "estimating value" part. The legal line between a CMA and an appraisal in New Jersey has its own page: CMA vs. appraisal.

What does the Valuation section cover?

PSI's outline (Section III, Sales 8%) lists these items:

On the New Jersey side, remember the rule behind item A.2. Only a state licensed or certified appraiser may perform an appraisal assignment on NJ real estate, but the appraiser law doesn't stop a licensee from giving pricing advice directly to an owner or buyer (N.J.S.A. 45:14F-21). A written CMA must state that it isn't an appraisal (N.J.A.C. 11:5-6.1(m)).

Which economic principles show up most?

Expect definition questions where you match a principle to a short scenario:

• Supply and demand. Value rises when buyers outnumber available properties and falls when they don't.
• Substitution. A buyer won't pay more for a property than the cost of an equally desirable substitute. The sales comparison approach rests on this idea.
• Highest and best use. The legally permitted, physically possible, financially feasible use that produces the highest value.
• Conformity. Value tends to hold up best when a property is reasonably similar to its neighbors.
• Progression and regression. A modest house among larger ones tends to gain value from the neighborhood (progression). The biggest house on a modest block tends to lose some (regression).
• Contribution. An improvement is worth what it adds to market value, not what it cost.
• Anticipation. Value reflects the benefits a buyer expects in the future, which is why income property is valued on expected income.

A memory trick: if the question mentions an "over-improved" house, think regression and contribution. If it mentions a buyer comparing options, think substitution.

How does the sales comparison approach work?

You start with recent sales of similar properties (comparables) and adjust each comparable's price to make it look like the subject property. The rule that trips people up:

• If the comparable is better than the subject, subtract the value of the difference from the comparable.
• If the comparable is worse than the subject, add the difference to the comparable.

Example: A comparable sold for $410,000. It has a garage worth $15,000 that the subject lacks, and it's missing a $5,000 deck that the subject has. The adjusted price is $410,000 − $15,000 + $5,000 = $400,000.

This is the go-to approach for single-family homes and vacant lots where there are enough recent sales. It's also how a CMA works, though a CMA is usually less formal.

How does the cost approach work?

The formula: value = land value + (cost to build new − depreciation).

Land is valued separately because land isn't considered to depreciate. Know the two cost terms and the three kinds of depreciation:

• Reproduction cost means building an exact replica. Replacement cost means building something with the same usefulness using current materials.
• Physical deterioration is wear and tear, such as an old roof.
• Functional obsolescence is an outdated design, such as a bedroom you can only reach through another bedroom.
• External (economic) obsolescence is caused by something outside the property, such as a new highway next door. It's generally treated as incurable by the owner.

Example: Land is worth $120,000. The building would cost $300,000 to replace, and depreciation totals $45,000. Value = $120,000 + ($300,000 − $45,000) = $375,000.

The cost approach fits new construction and special-purpose buildings that rarely sell, such as churches, schools or firehouses.

How does the income approach work?

For income-producing property, value comes from the income the property earns:

Value = net operating income ÷ capitalization rate

Net operating income (NOI) is the income left after vacancy, collection losses and operating expenses. Mortgage payments are not an operating expense, which is a classic trap answer.

Example: A building's potential gross income is $90,000. Vacancy and collection loss is $4,500 and operating expenses are $31,500, so NOI = $54,000. At an 8% cap rate, value = $54,000 ÷ 0.08 = $675,000.

For smaller rentals, you may see a gross rent multiplier: value = monthly gross rent × GRM. The same cap-rate formula, turned around, appears in the math section. Our NJ exam math guide has the full list of calculations.

What is reconciliation, and what are the appraisal steps?

An appraiser who uses more than one approach doesn't average them. They reconcile, giving the most weight to the approach that fits the property best. For a house that's the sales comparison approach, and for an office building it's usually the income approach.

The general steps (outline item A.3) run in this order: define the problem, gather and analyze data, decide on the highest and best use, estimate land value, apply the approaches, reconcile, and report the value opinion.

How should you study this section?

1. Drill the add/subtract rule until you can do it without thinking: adjust the comparable, never the subject.
2. Pair each approach with a property type: homes go with sales comparison, new or special-purpose buildings with cost, and rentals with income.
3. Keep the legal piece separate. A CMA, a BPO and an appraisal are different things under NJ law. Review them with the CMA vs. appraisal guide.
4. Practice in mixed sets, since PSI doesn't group questions by topic. Our Practice Exams page has timed practice, and Property Ownership on the NJ Exam covers the neighboring outline section.

Self-check (answers below):

1. A comparable has a pool worth $20,000 that the subject lacks. Do you add or subtract?
2. Which approach best fits a 100-year-old church?
3. NOI is $36,000 and the cap rate is 9%. What's the value?
4. A busy highway is built next to a home. What kind of depreciation is that?

Answers: 1) Subtract $20,000 from the comparable. 2) Cost. 3) $400,000. 4) External (economic) obsolescence.

Valuation is part of the NJ salesperson curriculum. Business Elementary's 75-hour pre-licensing course page explains how the course works.

Frequently Asked Questions

How much of the NJ real estate exam is valuation?

Valuation is 8% of the salesperson content outline's national portion (PSI bulletin).

Do you adjust the subject property or the comparable?

The comparable. Subtract when the comparable is better and add when it's worse.

Is depreciation applied to land in the cost approach?

No. Land is valued separately and isn't depreciated. Depreciation applies to the improvements.

Are mortgage payments subtracted to get net operating income?

No. NOI is figured before debt service. Subtract only vacancy, collection losses and operating expenses.

Can a NJ real estate agent do an appraisal?

Not an appraisal assignment, unless they're also a state licensed or certified appraiser. Agents can give pricing advice and prepare CMAs (N.J.S.A. 45:14F-21; CMA vs. appraisal).
