“A listing price expresses an offer; a completed transaction records a different event. A market page becomes misleading when it combines the two without definitions. Saudi official price-index methodology and professional valuation standards provide context for an original evidence checklist that keeps observed asking data separate from transaction evidence.

Saudi official price-index methodology and professional valuation standards provide context for an original evidence checklist that keeps observed asking data separate from transaction evidence.
Name the observation honestly
If your dataset comes from advertised listings, call it advertised asking-price data and state the collection period. Do not imply those amounts were accepted by buyers. Remove or explain duplicate and withdrawn records where your method requires it. A chart should describe what was actually observed, not the result the marketer wishes to communicate.
Understand official index scope
Read the official methodology to see what the statistical series measures and how its categories are defined. An index cannot be inserted into a listing-price table as though it were another property record. It describes a structured aggregate, while a particular valuation requires evidence appropriate to the asset, date and purpose.
Keep comparability visible
Different property types, areas, tenure conditions and observation dates may make prices unsuitable for direct comparison. Identify those boundaries before producing an average. An original research brief should show inclusion rules and missing information rather than presenting a precise number that conceals a heterogeneous collection of properties and marketing offers.
Explain uncertainty to the reader
A useful report can say that the evidence is incomplete or descriptive without pretending to be a formal valuation. Keep marketing interpretation separate from a qualified professional’s conclusion. The goal is a clearer discussion of available data, not a promise that a published asking price establishes market value or that a general index predicts a particular sale.
Preserve evidence labels in a presentation
A short sales deck can retain labels such as advertised asking evidence and recorded transaction evidence without overwhelming the reader. Use separate panels if the records cannot be reconciled. The presenter should be able to explain the source and collection boundary. A visually uniform chart is not a reason to merge different evidence types into an average that suggests more certainty than the dataset supports.
