1- Location, and existing buildings.
2- Determination of the type of ownership of the existing property.
3- Determination of the value to be appraised (varies according to the value to be determined).
4- Determination of the purpose of the appraisal (this is done by agreement between the appraisal applicant and the expert).
5- Determination of the date of the evaluation.
6- Determination of any special factors that limit the value of the appraisal: these determinants are to protect the estimator, and inform the report student about the determinants of the evaluation.
