Investment Trust (REIT), which raise funds through issuance ofsecurities to various investors. The funds are used mostly 10 acquire income-yielding .properties. The investors receive periodic distribution ofthese incomes and also participate in capital appreciation that may arise. To acquire these properties, valuation advice is sought from retained estate valuers. who mostly use traditional methods of valuation for the appraisal. This gives rise to variances in values obtained, thus causing. delays and sometimes termination of transactions. that would have enhanced the level of profitability of the REITs. The researchers seek to examine the effects of the use ofthese traditional methods on performance of Nigerian REITs and provide an alternative means of appraising through contemporary methods. Relevant data collected through questionnaire were analysed through ANOVA tool and SPSS 20.0. Analysis showed that use of traditional valuation methods are the most probable cause of variances in values obtained by REITs valuers. These variances may delay or terminate transactions and adversely affect the efficient operations of REIT.<; and their profitability. Use of contemporary methods of assessment will close the gaps in values and improve therefore, the level of efficient. operations and profitability of REITs in Nigeria.
