View Property Appraisal in Upland: How a View Is Measured Against Closed Sales

A view is measured against closed sales; it is never simply described into the value. The appraiser records what the view is, how much of it can be seen and from which rooms, and whether it could be blocked, then compares the house with sales of homes that have similar views and homes that have lesser ones. The view adjustment comes from the difference buyers actually paid, where the sales show one. In Upland that means a view home at the north end of the city is compared with other view sales, never with flat lots that get no adjustment at all.

This article belongs to the Hillside, Custom and Luxury Homes series. Its pillar, appraising a one-off house, sets out the wider method for hillside, custom and view homes.

Where Upland's view homes are

Upland's housing follows Euclid Avenue. Downtown holds the historic districts and the Euclid Avenue District; south of the 210 the city is largely postwar and later tract housing. North of the freeway the land rises toward the foothills, with larger lots and view homes. Above the city limits sits San Antonio Heights, an unincorporated community that San Bernardino County places "north of the City of Upland adjacent to the Angeles National Forest," with large lots and horse-keeping character. It is outside the city but inside the county, so the same assessor applies while city rules do not.

For an appraiser that makes the north end its own market. A view, lot usability and access decide the comparable search there, and the Upland area page describes how each of the city's pockets sells to its own buyers.

What the report records about a view

Before any adjustment, the view has to be described in terms a reviewer can check against the photographs:

• What is seen. The valley floor, the mountains, city lights at night, or a neighbor's roofline.
• How much of it. A wide, open outlook, or a slice between houses and trees.
• From where. The main living areas, or only a bedroom or the far end of the yard.
• How lasting. Whether a vacant lot below, growing trees or a future structure could narrow it. The report states what can be seen on the effective date, the date the opinion of value applies to, and notes any obvious threat to it without predicting one.

The same description is written for each comparable, because a view adjustment only means something when both sides of the comparison are described the same way.

How a view adjustment is measured

A view adjustment is the amount added to or subtracted from a comparable sale's price to account for a better or worse view than the subject's. Fannie Mae's Selling Guide states the rule plainly: "the appraiser's adjustments must reflect the market's reaction." It lists among unacceptable practices the "use of adjustments to comparable sales that do not reflect market reaction to the differences" and "not supporting adjustments in the sales comparison approach."

The strongest evidence is a paired-sales comparison, two closed sales alike in most respects except the feature being measured. In a market with few view sales, true pairs are rare, so the appraiser looks at groups of sales with and without comparable views, checks the pattern against other differences, and summarizes the evidence in the report. Listings and asking prices are not that evidence; closed sales are. If the sales show no measurable difference for a particular view, the report says so instead of inventing one. There is no rule of thumb for what a view is worth.

When there are too few view sales in Upland

The comparable radius, the distance from the subject within which comparable sales are searched for, often has to widen for a north Upland view home. Fannie Mae acknowledges that "there may be a shortage (or absence) of recent truly comparable sales in the immediate vicinity," and that the appraiser then "needs to decide whether an expansion of the market area search is appropriate." When a sale comes from outside the subject's market area, the report must "provide commentary to explain the rationale," and "the appraiser must not expand the neighborhood boundaries just to encompass the comparables selected."

In practice the wider search runs along the foothills. Alta Loma, in Rancho Cucamonga to the east, has custom homes with views across the valley, on the same San Bernardino County side. Claremont's foothill neighborhoods, Claraboya and Padua Hills, lie to the west across the county line in Los Angeles County; an Upland appraisal uses Upland sales first and explains any Claremont sale it relies on, with the location adjustment stated. Why view, grade and access widen the comparable search in Claraboya shows the same reasoning from the Claremont side.

Sparse sales also mean older ones. A time adjustment, the change applied to an older sale's price to bring it to the effective date, "must be supported by evidence," and the report "must, at a minimum, summarize the supporting evidence."

Grade, access and the lot under the view

A view lot often trades usable area for outlook. The house may sit on a pad above a slope, with a steep driveway and retaining walls holding the yard in place. Those are site improvements, the work done to the land itself such as grading, retaining walls, terracing and driveways, and they are described and adjusted separately from the view where sales support it. Folding them into one large view adjustment hides the reasoning a reviewer wants to see. The custom home article covers how construction quality is handled on the same kinds of lots.

What a reviewer throws out in Upland

• A north Upland view home compared with flat lots and no view adjustment.
• A San Antonio Heights large lot compared with a city tract house because the tract house was nearer.
• A Claremont sale used for an Upland house with no location adjustment.
• A view adjustment stated as a number with no market evidence summarized behind it.

Whether a higher price changes any of this is the subject of does a higher price tier change the method. It does not change the rule that every adjustment rests on closed sales.

Next step

The hillside and custom home appraisal page lists what the report includes and what helps, such as plans and any grading or retaining wall reports. To schedule, send the address and the purpose of the report through the order form, or call (909) 324-6122. The inspection runs longer than the 30 to 60 minutes of a standard single-family home, and reports are typically delivered three to five business days from the inspection. The fee is set by the scope of the assignment and quoted before work begins, and it does not depend on the value.
