Scoring methodology v1.0
How MARA works
MARA shows you how it reached a conclusion, not just what it concluded. These pages document every score, every estimate and every data source in the product — including what MARA does not know.
Introduction
How MARA works
What MARA is, what it calculates itself, and what it asks an AI model to do.
How MARA scores properties
The single 0–100 scale and the band labels used everywhere in the product.
The four score types
Property Score, Investment Score, Risk Score and User-Weighted Score are different things.
Property Analysis
Property Score
MARA's overall 0–100 assessment of a single property.
Price assessment
How MARA labels a price as underpriced, fair or overpriced.
Investment Score
A relative analytical score for investment characteristics — not a return forecast.
Risk Score
An inverted score: higher means more identified risk.
Comparisons
Renovations
Inspections
Offer Analysis
