What supports classifying a functional deficiency as economically curable?

Correct Answer

B) Its full supported value benefit justifies the full cure cost.

Physical feasibility, owner intent and age alone do not establish economic curability. Compare the full supported cure cost with its value benefit; under the stated exclusive alternatives, the benefit must justify cost. The depreciation amount still must fit the chosen cost base.

Answer Options
A
A contractor confirms the work is physically possible.
B
Its full supported value benefit justifies the full cure cost.
C
The owner intends to fix the deficiency within the coming year.
D
The building is under 20 years old, with no cost-benefit check.

Why This Is the Correct Answer

Option B is correct because functional obsolescence is curable when the cost to cure is equal to or less than the value added by curing it. When the full supported value benefit justifies the full cure cost, the cure makes economic sense. That cost and benefit comparison is what supports the curable classification.

Why the Other Options Are Wrong

Option A: A contractor confirms the work is physically possible.

Option A relies on a contractor confirming the work is physically possible. Many cures are physically possible but cost more than they add in value, so physical feasibility alone does not make a deficiency economically curable.

Option C: The owner intends to fix the deficiency within the coming year.

Option C relies on the owner's intent to fix the deficiency within the coming year. An owner's plans do not change whether the cure cost is justified by the value gain; curability is a market test.

Option D: The building is under 20 years old, with no cost-benefit check.

Option D relies on the building being under 20 years old, with no cost-benefit check. Building age does not determine curability; the cost to cure must still be compared with the value benefit.

Benefit covers cost, curable

If the value gained from the fix is at least as much as the fix costs, the item is curable.

How to use: Use this test on any question asking whether a functional item is curable.

Exam Tip

Look for the answer that compares cost to cure with value gained. Feasibility, intent and age are common distractors.

Common Mistakes to Avoid

  • -Treating physical feasibility as proof of curability
  • -Relying on the owner's repair plans
  • -Using building age as a curability test

Concept Deep Dive

Analysis

This question tests the economic test for curable functional obsolescence. A deficiency is curable when the value gained from curing it is equal to or greater than the cost to cure. Physical feasibility, owner plans and building age do not by themselves meet that test.

Background Knowledge

Curable functional obsolescence exists when a prudent buyer would pay to correct the item because the value gained equals or exceeds the cost. Incurable functional obsolescence exists when the cure cost exceeds the benefit. The test is economic, not physical, and it relies on market evidence of the value benefit.

Real-World Application

An appraiser notes a home with an outdated electrical panel that buyers in the market discount heavily. A contractor's estimate to replace it is less than the price difference shown by comparable sales, so the appraiser treats the item as curable functional obsolescence.

More Cost Approach Questions

Why can equivalent-utility replacement cost be useful for an obsolete improvement?

An appraiser estimates the current replacement cost new of the improvements at $890,000, accrued depreciation from all causes at $170,000, and land value at $325,000. All necessary cost components and depreciation are included in those amounts. What is the indicated property value?

Improvement cost new is $595,000. Separately supported improvement depreciation deductions of $48,000, $27,000 are expressly nonoverlapping and not already excluded from cost new. Add supported site value of $155,000, already reflecting any site losses. What total indicated value results?

What best supports a claimed loss from a bathroom-layout deficiency?

Improvement cost new is $1,850,000. Separately supported improvement depreciation deductions of $310,000, $620,000 are expressly nonoverlapping and not already excluded from cost new. No site is included. What depreciated improvement amount results?

Which scenario most strongly supports giving the cost approach substantial weight?

A cost total $650,000 explicitly includes $40,000 of non-realty FF&E outside the appraised real-property interest. Exclude it. Supported realty-only total depreciation is $55,000. Add site $200,000, with no overlap. What real-property cost indication results?

A 2,200-sf dwelling costs $200 per square foot, and a separate 400-sf garage costs $75 per square foot. These costs are complete and do not overlap. Both have an effective age of 15 years and a total life of 50 years, with straight-line depreciation and no salvage value. No site value or other loss is involved. What is the combined depreciated cost of the dwelling and garage?

A new feature in the improvements has a current cost of $45,000 and a market contribution of $18,000. The entire difference is due to superadequacy, with no physical or external loss and no overlap. What is the loss from the superadequacy?

An external influence causes an annual net income loss of $9,600. The capitalization rate for the loss is 8%, and no other economic factors change. What is the indicated loss in value of the whole property, before allocation between site and improvements?
