AI valuation vs official appraisal: what each is worth and for what

An official appraisal (certified company, Orden ECO/805/2003) is used for a mortgage, inheritance or court. A commercial valuation with AI is used to set a selling or buying price and argue it. They do not replace each other.

How it works

Legal framework (indication, "should be verified"); what each use requires; risks of an AI "writing" the value; why arithmetic must be deterministic and auditable.

How Nexus does it

The AI does not write the final value; the engine calculates and documents it. Nexus does not issue official appraisals.
