    Valuation of Regional Malls 06/10/2015 Presented by Peter F. Korpacz, MAI, CRE, FRICS, Korpacz Realty Advisors, Inc.
    The valuation of regional malls is a continuing exercise that presents a number of unique issues. Mall classification methodology is very important within the mall part of the retail industry, but is not yet fully understood and embraced by appraisers. Fee simple and leased fee property interest controversies have needlessly complicated cap rate derivation and other valuation methodology and techniques. Lack of understanding of how malls operate and how investors view their positive and negative performance issues often results in methodology mistakes. This presentation will look to the marketplace to resolve these items and various other issues arising under all three traditional approaches to value.
