A website has posted and collated all of the data used in residential property appraisal (assessment) between 2005 and 2010 for a city in Morgantown WV and presented it such that evidence that sales chasing and non-appraisal has been going on for a long, long time. All of the data are directly from the IAS system Here's a link to a doozy - http://monfairassessments.org/parcel_search_new.php?ID=12-14-0296-0000-0000 The person who purchased the home saw a 146% increase in their appraisal the year after they purchased the home as a result of the assessor jiggering the dwelling grade (C+ to A+), CDU (0.6 to 0.97), and land price per front foot ($184/ft to $363/ft). Interesting that neighboring properties have had the same grades, CDUs and prices per front foot every year. Wonder how well the owner would do on appeal to the courts? Would this constitute fraudulently altering public records for personal gain (i.e. hiding the fact that you aren't assessing property from the Tax Commissioner by jacking up the assessments on sold properties since the Commissioner only looks at assessed to sales ratios for sold properties to grade the assessor)? Is this Captain Obvious or what?
