HARD

An appraiser is valuing a 1950s bungalow with a detached workshop. None of the recent neighborhood sales can be paired to isolate what a workshop adds, so the appraiser bases the adjustment on the workshop's current replacement cost less depreciation. Which adjustment technique is the appraiser using?

EASY

The subject property is a split-level home with no deck. A comparable sale has a 12-year-old wood deck that has been well maintained and has an effective age of 5 years. Decks of this type have a total economic life of 20 years, and a new deck of the same size and materials costs $16,000 to build today. Market data show buyers in this area pay about the depreciated cost of a deck. Using cost analysis, what amount indicates the deck's contribution?

MEDIUM

A comparable ranch home in good repair sold for $318,000. The otherwise similar subject has a furnace that does not work and peeling exterior paint. Replacing the furnace costs $6,200, plus $700 to remove the old unit, and repainting costs $4,100. Both homes had their roofs replaced two years ago at a cost of about $12,000. Market data show buyers reduce their price by about the cost to cure items like these. What is the comparable's sale price adjusted for condition?

HARD

Homes in a tract subdivision of three-bedroom ranches sell between $290,000 and $330,000. The owner of the subject built a 1,000-square-foot heated garage with a workshop at a cost of $110,000, and no other home in the area has a similar building. The appraiser's depreciated cost estimate for the building is $100,000. Why is that figure likely to overstate the building's contribution to value?

MEDIUM

Market data in a suburban area show buyers react to roof age in line with depreciated replacement cost. A comparable two-story colonial has a 2-year-old asphalt shingle roof. The subject's roof of the same type is 16 years old and in typical condition for its age. Shingle roofs in this market last about 20 years, and a new roof for either house costs $14,000. What roof adjustment applies to the comparable?

HARD

Unlike the subject duplex, a comparable duplex has a second-floor half bath. The seller's records show the half bath cost $22,000 to add in 2016. A contractor's current estimate to build the same half bath is $15,000, which includes $800 in permit fees, and the appraiser estimates 20% depreciation. Market data show buyers in this area pay about the depreciated cost of an added bath. What adjustment applies to the comparable?

MEDIUM

In a subdivision where about half the homes have detached two-car garages, an appraiser estimates the depreciated cost of a comparable's 3-year-old garage at $28,000. Two pairs of recent sales of otherwise similar homes, each pair differing only by a detached two-car garage, show price differences of $17,000 and $19,000. The subject has no garage. What garage adjustment to the comparable does the evidence best support?

HARD

Comparable 2 sold for $415,000. A year before the sale, its owner added a full bath that the subject lacks; the bath would cost $30,000 to build today and shows 5% depreciation. The subject has a covered patio that the comparable lacks, with a depreciated cost of $6,000. Market data show buyers in this neighborhood pay about the depreciated cost of recent, well-built additions like these. What is the comparable's adjusted sale price?

HARD

The subject property, a 1980s two-story home, has no patio. Comparable 1 has a one-year-old paver patio of the size and quality most homes in the neighborhood have. The one recent pair of sales that differ by a patio also differ in gross living area, condition and lot size, and the market gives no measure of those other differences. A local contractor has quoted a current price to build the same patio. Which evidence better indicates the patio adjustment to Comparable 1?

EASY

In a neighborhood of 1970s split-level homes, none of the recent sales can be paired to isolate four features that some comparables have. The appraiser is deciding which feature's adjustment can rest most safely on its depreciated cost. Which feature is the best candidate for a cost-based adjustment?

MEDIUM

A builder is still selling homes in the subdivision where the subject property, a new two-story home, is located. The subject's buyer chose the builder's finished-basement option, and Comparable 2, the same model sold by the same builder last month, has an unfinished basement. The builder's current price list shows the finished-basement option at $31,000, and the builder's sales manager says options carry a 20% gross margin. A 2019 cost manual shows $22.50 per square foot for 900 square feet of basement finish. Both homes have the builder's $12,000 kitchen upgrade package. Agents active in the subdivision report that buyers treat the option as adding about what the builder charges. What amount should be added to Comparable 2's price for the basement finish?

MEDIUM

The subject property and a comparable sale are both two-story homes with detached two-car garages built at the same time as the houses and in similar condition. A cost service shows the garage would cost $32,000 to build new, and the appraiser estimates it is 25% depreciated. Using cost analysis, what adjustment should be made to the comparable for the garage?

EASY

In a coastal area where many homes have backup power, the subject property has a two-year-old whole-house standby generator, and Comparable 2 has none. No paired sales isolate the generator, and market data show buyers pay about its depreciated replacement cost. The appraiser has four cost figures: a local installer's current bid of $13,500 to install the same model; the manufacturer's current catalog price of $8,900 for that model, which covers the unit only; a cost manual figure for a lower quality class of generator; and the $16,000 the subject's homeowners policy lists as the generator's insured value. Which figure is the best starting point for the adjustment?

MEDIUM

Two recent sales are available to measure the value of a screened porch. Sale A, with a screened porch and a garden shed, sold for $356,000. Sale B, with neither, sold for $338,000. Both sold last month in the same subdivision and are alike in every other respect. Market data show sheds of this kind add about their depreciated cost, which for this shed is $4,000. The porch's depreciated replacement cost is $20,000. What porch adjustment does this pair indicate?

HARD

A single-family home with a permitted garage apartment is being appraised, and a comparable sale has no apartment. Leases in the neighborhood show homes with a garage apartment rent for $2,950 per month and similar homes without one for $2,350. Leased separately, a garage apartment rents for about $850 per month. The owner pays about $100 per month for the apartment's utilities. The apartment cost $84,000 to build six years ago. Rented single-family homes in the neighborhood sell for about 150 times their monthly rent. What adjustment amount is indicated for the garage apartment?
