Determinants of vacant land values and implications for appraisers.When real estate professionals, especially appraisers, are called on to appraise appraise v. to professionally evaluate the value of property including real estate, jewelry, antique furniture, securities, or in certain cases the loss of value (or cost of replacement) due to damage. land, they must determine the effects and importance of area factors such as distance to the central business district (CBD (Component Based Development) Building applications with components (objects). See component software.
CBD - component based development ) and population, as well as traditional property factors such as parcel size. Land sales in a "growth" location within a metropolitan area are evaluated and compared in an attempt to better understand the variables that influence land prices. The area examined in this study is easily accessible to major limited access highways, thus enhancing its desirability for development and growth.
The metropolitan area's growth coincides with the pattern of development for many modern cities characterized by Arthur Sullivan as a system of urban villages, or suburban subcenters where increases in population, retail stores, and medical service providers follow a pattern consistent with a multicentric suburbanized city.(1) It is important to understand factors affecting vacant land values, especially in rapidly growing areas. The use of geographic information systems (GIS) technology in the land valuation models is also demonstrated.(2)
The sales data are based on recorded transfers of vacant land (except for single-family residential lots) as reported by the Clerk of Courts' offices in Caddo and Bossier Bossier may refer to:
The study area is located in the northeast sector of the metropolitan area near 1-20 and 1220. This area has shown rapid development in recent years, with higher concentrations of sales in the $90,000 range [ILLUSTRATION FOR FIGURE 2 OMITTED]. Growth in this area has been attributed to both the expansion of Barksdale Air Force Base Barksdale Air Force Base is a United States Air Force base across the Red River from Shreveport. Louisiana and near Bossier City, Louisiana, that was established in 1933. , the addition of riverboat casinos, intraurban migration (from Shreveport and Bossier City Bossier City (bō`zhər), city (1990 pop. 52,721), Bossier parish, NW La., on the Red River, across from Shreveport, with which it is connected by several bridges; inc. 1907. Barksdale Air Force Base, home of the Second U.S. ), and immigration immigration, entrance of a person (an alien) into a new country for the purpose of establishing permanent residence. Motives for immigration, like those for migration generally, are often economic, although religious or political factors may be very important. from people outside the metropolitan area. (The two riverboats in Bossier City, along with one in Shreveport, are permanently docked and each has gross revenues of approximately $13 million per month.)
The ordinary least squares procedures are employed to estimate a land valuation model where the logarithm logarithm (lŏg`ərĭthəm) [Gr.,=relation number], number associated with a positive number, being the power to which a third number, called the base, must be raised in order to obtain the given positive number. of the price per acre is the dependent variable. The price is adjusted for inflation, using the Consumer Price Index. During the time frame examined, 1984-1995, the local economy experienced a moderate decline in real estate prices, followed by a leveling off with price increases near the end of the time period. In general, vacant land in this area did not experience large declines, probably because most landowners adopted a wait-and-see approach. The independent variables are:
1. The zoning classification (ZB)
2. The logarithm of parcel size in number of acres (LACRES)
3. The logarithm of the distance to the central business district in number of miles (LCBD LCBD Light Chain Binding Domain )
4. The logarithm of the population in the region (LPOP LPOP Listening Post Observation Post
LPOP Local Point of Presence (nternet/digital communications)
LPOP Little Piece of Paradise )
The metropolitan area has not used zoning to preserve farmland. (Zoning changes from agricultural to business are routinely granted unless the new use will be detrimental to neighboring residential uses; agricultural to residential zoning use is also routinely granted.) Rather, land is often maintained in an agricultural classification by the owner to take advantage of the low property tax burden. Typically zoning changes have been relatively easy to secure except for occasional cases involving controversial uses such as video poker Video poker is a casino game based on five-card draw poker. It is played on a computerized console which is a similar size to a slot machine.
Video poker first became commercially viable when it became economical to combine a television-like monitor with a . In the model the zoning variable (ZB) takes on a value of 1 for business zones and 0 otherwise.
Distance to the CBD, calculated using GIS procedures, is included as a measure of accessibility. It is expected that locations closer to the CBD will have higher values.

After the regions are established, the variable, the size of the population, is calculated using GIS procedures. It is also expected that greater population leads to higher demand for retail and business land use and thus higher land value. The population variable is based on the underlying census block A census block is the smallest geographic unit used by the United States Census Bureau for tabulation of 100-percent data (data collected from all houses, rather than a sample of houses). Several blocks make up block groups, which again make up census tracts. data and includes 1990 census data as well as projections for the years 1984-1990 and 1991-1995.(3) Summary statistics for all the variables are reported in table 1.

regression coefficient , indicating that, as might be expected in vacant land sales, the smaller parcels tend to sell for more per acre than do the larger parcels. Often the larger parcels involve more development work and sometimes result in unused segments sold to other businesses later.

The population variable is significant and positive for this area, indicating that as the population increases, land values also increase. Distance to the CBD is significant and negative, indicating that a greater distance from the CBD decreases land values. In recent years, more new activities and land sales have actually taken place farther from rather than closer to the CBD.
The existence of a B zoning classification (business zoning) is proof positive for the area, an indication that this type of zoning contributed, as expected, to higher land prices. Business zoning is the prevalent type of zoning (often with retail, hotel, and medical facilities uses) in this study with some residential, agricultural, and industrial zoning classes identified to a lesser extent.
This model may be used to estimate vacant land values. For example, using the average values for the independent variables as found in table 1 results in a price per acre of $41,357. This is found by substituting 0.43 for LACRES (which translates into 1.54 acres), 8.44 for LPOP (equivalent to 4,628 persons), 1.32 for LCBD (equivalent to 3.74 miles) and 0.59 for zoning. For example, the equation:
Log price = -2.584 + -0.3217 (log of acres) + 1.674 (log of population) - 1.432 (log of distance from CBD) + 1.88 (zoning class value)
Log price = -2.584 + (-0. 3217)(0.43) + (1.674)(8.44) - (1.432)(1.32) + (1.88)(0.59)
The result is a value estimate of 10.63 for the log of price per acre, which is $41,357 per acre. In a separate test, the year 1984 is used as a base year, and a dummy variable for each year from 1985 to 1995 was added to the model. The purpose is to see whether time is an important explanatory variable in addition to inflation. The results show that land value was significantly different from 1984 in only three years: 1985, 1987, and 1995. Thus, it appears that the inflation-adjusted model accounts for the effects of time.

sub·cen . The distance to the CBD is generally significant and negative. This finding is not surprising since more of the development has been taking place on the fringes of the urban area, and as expected, population was positive, showing that increasing population results in higher values. The existence of business zoning always has a positive influence on the price per acre, and the size of the parcel is inversely related to sales price.
