Class is for General and Residential appraisers, Realtors, Assessors, and all Real Estate professionals.

Many, if not most, valuation assignments involve a straight-forward application of the cost, income and sales-comparison approaches to value. However, frequently more complex issues arise as there are many different economic forces that can influence the value of real estate. Some complex issues are beneficial and might result in an increase in value, such as discovering minerals or oil on grazing land, whereas others are detrimental such as natural or environmental disasters.


Within the different approaches to value, real estate appraisers can utilize a variety of techniques such as regression, paired sales, sale/resale, literature reviews, case studies, loss of use, project delay, and so forth. This course will present a general overview of the different techniques, including examples utilized in different complex valuation situations, and facilitate discussion.


Additionally, many class action lawsuits seek to address these complex valuation issues across numerous properties. The real estate appraisal profession plays an essential role in these lawsuits, as USPAP sets forth Standards 5 and 6, to address mass appraisal assignments. The course will also give a general overview of the different mass appraisal techniques an appraiser can consider and how these techniques can be utilized in mass-complex valuation assignments.

From Wikipedia:

Randall Bell (born 1959), is a socio-economist,[5] real estate economist and appraiser,[1] expert witness,[6] and author based in Los Angeles, California known for dealing with stigmatized property.[7][8] Bell is an expert on real estate damages,[6] who authored a highly-referenced textbook on the subject,[9][10] and was called "Dr. Disaster" by The Wall Street Journal.[11] Bell's notable cases include: Nicole Brown Simpson's Los Angeles condominium, the mansion where 39 Heaven's Gate members died of suicide, the JonBenét Ramsey's house in Colorado, the World Trade Center site, and properties damaged in the Rodney King riots and by Hurricane Katrina.[10][12][13]

Bell grew up in Fullerton, California as the son of an engineer and homemaker, and attended Troy High School.[14] He has an MBA from UCLA.[7][10][13] He received his doctoral degree from Fielding Graduate University in Santa Barbara, California, with a dissertation on the socioeconomic reasoning of Hurricane Katrina survivors.[4]

Bell began working on appraisals of environmental and asbestos damage in the 1980s.[11] He has also assessed Chinese drywall and sink holes.[6][10] In 1992, Bell assessed the damages of the Rodney King riots in Los Angeles. After the riots, he decided to focus only on damaged properties. Also in 1992, Bell created the Bell Chart, a rating system that categorizes the 10 types of detrimental conditions and their corresponding economic damages of properties.[8][14][11] The system ranks properties from class 1 (no detrimental effects) to class 10 (an incurable condition).[11] In 1994, he began assessing stigmatized properties such as the damages of the Northridge earthquake and wildfires in Malibu, California.[15][13] In 1997, he became the national director of the Real Estate Damages practice of Price Waterhouse.[10] He left the firm in 1999, and co-founded Bell Anderson & Sanders with two partners.[10] He is presently CEO of Landmark Research Group.[16]

Bell works with properties that have been affected by crime, environmental contamination, construction defects, reported hauntings, and natural disasters.[15][17] He has consulted on Nicole Brown Simpson's condominium; the Beverly Hills estate where Charles Manson's followers murdered Sharon Tate and four other people in 1969; the Rancho Santa Fe mansions where the bodies of 39 Heaven's Gate cult members were found, the house in Boulder, Colorado, where JonBenét Ramsey was killed; the home of Sandy Hook Elementary School shooter Adam Lanza; and the house of Las Vegas shooter Stephen Paddock.[2][14][10][13][11][18][19][20] He has also consulted on Hurricane Katrina; the Bikini Atoll in the Marshall Islands; the September 11 attacks at the World Trade Center; and the United Airlines Flight 93 crash site in Shanksville.[10][13] Bell has traveled to ChernobylHiroshima; to the World Trade Center site; and to EgyptJordanIsrael and West Bank to find comparisons in properties damaged by terrorist attacks.[6][11] He has also traveled to Antarctica to interview scientists about climate change and how it affects costs, such as insurance for home owners.[21] The Appraisal Institute published Bell's book Real Estate Damages: Applied Economics and Detrimental Conditions in 2008.[6] In 2011, Bell returned from Guam, where he consulted with landowners whose property included the cave where Shoichi Yokoi, a Japanese army sergeant, hid for 28 years, unaware that World War II had ended. The landowners opened a theme park on the property.[6]

In recent years, Bell has begun writing self-help books, inspired by his interactions with disaster victims and his personal experiences with overcoming trauma and obstacles.[9]

Bell hosted the 2020 docuseries, Distressed Real Estate, produced by Topic Studios.[22]
