City of Centerville <br />Residential Appraisal System <br />Per State Statute, each property must be physically inspected and individually <br />appraised once every five years. For this individual appraisal, or in the event of an <br />assessed value appeal, we use two standard appraisal methods to determine and verify <br />the estimated market value of our residential properties: <br />1. First, an appraiser inspects each property to verify data. If we are unable to view <br />the interior of a home on the first visit, a notice is left requesting a return telephone <br />call from the owner to schedule this inspection. Interior inspections are necessary <br />to confirm our data on the plans and specifications of new homes and to determine <br />depreciation factors in older homes. <br />E <br />To calculate the estimated market value from the property data we use a Computer <br />Assisted Mass Appraisal (CAMA) system based on a <br />reconstruction less depreciation method of appraisal. The <br />cost variables and land schedules are developed through an <br />row® analysis of stratified sales within the city. This method uses <br />the "Principle of Substitution" and calculates what a buyer <br />„T would have to pay to replace each home today less age <br />dependent depreciation. <br />'lam"' 3. A comparative market analysis is used to verify <br />these estimates. The properties used for these studies are those that most recently <br />have sold and by computer analysis, are most comparable to the subject property <br />taking into consideration construction quality, location, size, style, etc. The main <br />point in doing a market analysis is to make sure that you are comparing "apples with <br />apples". This will make the comparable properties "equivalent to" the subject <br />property and establish a probable sale price of the subject. <br />These three steps give us the information to verify our assessed value or to adjust it if necessary. <br />Sales Studies <br />According to State Law, it is the assessor's job to appraise all real property at market <br />value for property tax purposes. As a method of checks and balances, the <br />Department of Revenue uses statistics and ratios relating to assessed market value <br />and current sale prices to confirm that the law is upheld. Assessors use similar <br />statistics and sales ratios to identify market trends in developing market values. <br />A sales ratio is obtained by comparing the assessor's market value to the adjusted sales price of <br />each property sold in an arms -length transaction within a fixed period. An "arms -length" <br />transaction is one that is generated after a property has had sufficient time on the open market, <br />between both an informed buyer and seller with no undue pressure on either party. The median <br />or mid -point ratios are calculated and stratified by property classification. <br />12 <br />
