Is the Hypothetical Condition Necessary?

Hypothetical Conditions and Identifying the Interest Appraised

Joshua Walitt, Founder and CEO, Walitt Solutions

Why appraising the fee simple interest of a leased property does not require a hypothetical condition.

The appraisal scenario

In a recent class I instructed, the learners diverged to two camps:

Some believed a hypothetical condition was necessary in the appraisal of the fee simple interest of a leased property
Others believed the hypothetical condition was not necessary.

It is worth taking the issue step-by-step, because the disagreement was not about leases. Instead, it was about what a hypothetical condition is actually used for.

An appraiser is engaged to develop an opinion of market value of the fee simple interest in a property that is currently leased. The lease is significantly below market. The lease runs 60 months past the effective date. The lease would survive a transfer of ownership. The appraiser identifies the lease in the report, then develops an income approach using market rent rates.
The client’s reviewer rejects the report, saying the appraiser mentioned the lease but should have considered it in the valuation (which the appraiser did not). The appraiser pointed the reviewer to Standards Rule 1-4(d). The reviewer then asks the appraiser to remove any mention of the existing lease.

What actually triggers a hypothetical condition

USPAP defines a hypothetical condition as

“a condition, directly related to a specific assignment, which is contrary to what is known by the appraiser to exist on the effective date of the assignment results, but is used for purposes of analysis” (DEFINITIONS, page 4, lines 116 to 121).

The Comment to the definition states in part:

“Hypothetical conditions are contrary to known facts about the physical, legal, or economic characteristics of the subject property….” (Comments in USPAP have the same weight as the component they address.)

So the question is not whether something in the file feels counterfactual. The question is precisely:

Does the analysis assert something untrue about the subject property?

But we cannot answer that question yet! First, we must identify what the subject property is to be appraised. That is not a technicality. It is the entire crux of the issue, and most of the confusion comes from people running the hypothetical condition test before identifying what the subject property even is.

The subject is an interest, not a building

Standards Rule 1-2(e)(ii) requires the appraiser to identify the real property interest to be valued. It sits inside the broader requirement in Standards Rule 1-2(e) to identify the characteristics of the property that are relevant to the type and definition of value and the intended use.

Advisory Opinion 23 explains why the distinction matters. Taking the USPAP definitions of “real property” and “real estate” together, the subject of a real property appraisal is a specific ownership of a right (or rights) in identified real estate. Advisory Opinion 23 goes out of its way to note that appraisers and property owners habitually discuss the subject in physical terms, as “my home,” the “residence,” the “building,” and so on, but a physical component is not what is actually the subject of a real property appraisal (page 65, lines 39 to 40).

In the described assignment, the subject is the fee simple interest. Not the house, not the house-as-currently-rented.

In real property appraisal, we must remember we appraise PROPERTY RIGHTS. Without first knowing the rights to be appraised, we have not actually identified the subject property of the appraisal.

Subject identification and assignment conditions are different

This is where the need-a-hypothetical and do-not-need-a-hypothetical camps begin to diverge significantly.

The SCOPE OF WORK RULE’s Problem Identification section lists the assignment elements an appraiser must gather and analyze in order to identify the problem to be solved (pages 15 to 16), including as separate elements:

the subject of the assignment and its relevant characteristics, and
assignment conditions.

The Rule goes on to tell us what “assignment conditions” are (as does the Definitions section): assumptions, extraordinary assumptions, hypothetical conditions, laws and regulations, jurisdictional exceptions, and other conditions affecting the scope of work.

Identifying the fee simple interest as the subject property being valued must happen first (see Standards Rule 1-2(e)(ii)). Hypothetical conditions are identified later, because hypothetical conditions can only apply to an identified subject property.

Additionally, the Comment to Standards Rule 1-2(e)(i) through (v) states that an appraiser is not required to value the whole when the subject of the appraisal is a fractional interest, a physical segment, or a partial holding. The same Comment notes that identification of the real property interest appraised can rest on title descriptions or other documents setting forth known encumbrances. That sentence is describing encumbered real estate in which the interest appraised is identified separately (differently) from the encumbrance, which is exactly our scenario.

Now run the test on what the appraiser actually did

Let’s take the appraiser’s steps apart and check each assertion against the definition.

The appraiser identified the lease. That is required by SR 1-2(e)(iv), which specifically names leases among the encumbrances to be identified, and it is a true statement about the real estate.

The appraiser used his or her market rent opinion to develop the income approach. Market rent is the income attributable to an unencumbered fee. Contract rent is an attribute of the leased fee.

At no point does the analysis assert that the leases do not exist. The appraiser did not say “there is no lease.” In fact, the appraiser did disclose the lease existed, but stated, in effect, “the interest I am valuing is not the one this lease encumbers.” Nothing in the appraisal is contrary to a known fact about the identified subject. The hypothetical condition never fires.

(Compare FAQ 232 (page 242), which shows what a genuine hypothetical condition looks like. There, land is to be appraised as though a use-restricting covenant were in place when, as of the effective date, no such covenant exists. That analysis fabricates a characteristic the property does not have. Our scenario does something different in kind. It selects among characteristics that genuinely exist.)

And this is also why Standards Rule 1-4(d) does not apply: the obligation to analyze the effect on value of the terms and conditions of the leases attaches when developing an opinion of the value of a leased fee estate or a leasehold estate (page 21). The rule is conditional and the cited assignment is an appraisal of neither a leased fee estate or a leasehold estate.

The Appraisal Foundation offers three Frequently Asked Questions (FAQs)

FAQ 191 (page 223) addresses appraising only the improvements of an improved property. No hypothetical condition or extraordinary assumption is necessary in that case. The report must disclose that the land exists and is not included in the valuation.

FAQ 192 (pages 223 to 224) addresses appraising only the underlying land of an existing shopping center. Same answer. And the response goes further, listing among the permissible subjects of a real property appraisal the fee simple interest of a fully leased or otherwise encumbered property.

FAQ 233 (page 242) is our assignment precisely: a single-family rental, market value of the fee simple, a below-market lease that survives transfer. (The only difference to our scenario is the remaining term.) USPAP does not require the lease to be analyzed and reflected in the valuation, because the subject of the assignment is the fee simple interest, not the leased fee.

The Reference Index states the principle in a single line (page 317): where the subject is the fee simple interest, there is no USPAP requirement to also appraise a leased fee interest.

All three FAQ answers have in common: mandatory disclosure, but no hypothetical condition.

Reporting obligation

STANDARD 2 requires that each analysis, opinion, and conclusion be communicated in a manner that is not misleading (page 22). Standards Rule 2-1(a) and (b) require the report to set the appraisal forth clearly and accurately in a manner that will not be misleading, and to contain sufficient information for intended users to understand it properly. Standards Rule 2-2(a)(v) requires the report to state the real property interest appraised (page 23).

FAQ 233 addresses this exactly: disclose that a lease is in effect, and disclose that the value of the leased fee interest has not been reflected in the appraisal.

Adding a hypothetical condition “to be safe” is not appropriate

The last objection I usually hear is that a hypothetical condition might be unnecessary, but it cannot hurt. I disagree.

Standards Rule 1-2(g) permits a hypothetical condition

only if its use is clearly required for legal purposes, for purposes of reasonable analysis, or for purposes of comparison, and

only if its use results in a credible analysis (page 20).

That is a threshold to exceed, not a suggestion. Because the fee simple interest can be identified and valued directly, without asserting anything contrary to fact, the “clearly required” test is not satisfied. The analysis does not need a hypothetical condition to function.

Standards Rule 2-2(a)(xiii) then compounds the problem of an appraiser choosing to add an unnecessary hypothetical condition. Any hypothetical condition

must be stated clearly and conspicuously in the report, along with

a statement that its use might have affected the assignment results (page 24).

So a gratuitous hypothetical condition would be attaching a warning label to a value opinion, even though there is nothing to warn about, which contradicts STANDARD 2 requirements for clear and not misleading reports.

A note on the reviewer

The reviewer’s proposed fix was to remove any mention of the existing leases from the report. That request runs directly contrary to Standards Rule 2-1(a) and (b), to the disclosure that FAQ 233 emphasizes, and to the Conduct section of the ETHICS RULE (page 9), which prohibits an appraiser from using or communicating a report the appraiser knows to be misleading.

In short…

– A hypothetical condition means contrary to a known fact about the subject.
– The subject is the identified real property interest, not the physical real estate.
– In the scenario discussed, that interest is the fee simple, and USPAP expressly permits appraising less than the whole, including encumbered property.
– Nothing in the analysis is contrary to fact. Market rent belongs to the fee simple; contract rent belongs to the leased fee. (Fee simple interest is the subject property being appraised in our scenario.)
– Standards Rule 1-4(d) never triggers, because the assignment is neither a leased fee nor a leasehold.
– Therefore, a hypothetical condition is not appropriate.
– Disclosure is addressed by Standards Rules 2-1 and 2-2(a)(v).
– Adding a hypothetical condition “to be safe” fails the “clearly required” test in Standards Rule 1-2(g).

In the end, the appraiser identified which interest is the subject of the appraisal, and did not change what is true about that interest. Consequently, there is no hypothetical condition related to this particular scenario.
