Methodology
How By Side reaches a verdict
Every verdict is derived from DLD registered transactions — the only publicly authoritative record of what Dubai property has actually sold for. We apply consistent methodology to every analysis, and we label every input with its evidence state so the reader always knows what is known, what was provided, and what was estimated.
Structural rules
These rules cannot be overridden
- 01
The verdict is always the first element in a report. Nothing appears above it.
- 02
Ready and off-plan properties are never mixed in the same comparable set.
- 03
Evidence is always shown. Comparables and derivation logic are always visible.
- 04
Every figure carries an evidence label: Verified, Provided, Estimated, Observed or Missing.
- 05
Missing values are shown empty. They are never replaced with zero.
- 06
Listing prices are never mixed with registered DLD transaction prices.
- 07
No developer is given a reliability rating. Only verified facts, with source.
- 08
When evidence is insufficient to support a conclusion, we say so. We do not force a number.
Evidence classification
Every input is labeled with its evidence state
The figure is supported by a directly traceable authoritative source — a DLD registered transaction or an official document.
The figure was provided by the buyer, broker or another party. It is shown as entered; By Side has not independently verified it.
The figure is calculated from explicit assumptions using By Side methodology. The inputs and formula are shown.
Derived from an observed market dataset. The dataset source and recency are noted.
The information is not available or has not yet been verified. A verdict is never constructed around a missing value.
Internal domain values (declared, modelled) are preserved in all API and report outputs. Display labels only are mapped at the presentation layer.
