Home Value Methodology — How Reaixo Estimates Property Value | Reaixo

The data, adjustments and confidence scoring behind every Reaixo home value estimate — so you know exactly what stands behind the number.

A home value estimate is only as trustworthy as the method behind it. Reaixo's approach starts from the same principle a licensed appraiser uses — recent comparable sales are the strongest evidence of what a property is actually worth — then applies AI-assisted adjustments for the ways a specific property differs from those comparables.

What Data Goes Into the Estimate

  • Recent comparable sales — price, square footage, bed/bath count, lot size, age and sale date for similar nearby properties.
  • The subject property's own public-record characteristics — square footage, bedrooms, bathrooms, year built, lot size.
  • Local market trend indicators — median price direction, inventory levels, and average days on market in the area.
  • Condition information you provide — known issues, recent renovations, or upgrades that public records wouldn't reflect.

How Adjustments Work

Once comparable sales are identified, the model adjusts for the specific ways the subject property differs from each one:

  • Size — larger or smaller living area relative to comparables, adjusted on a price-per-square-foot basis.
  • Age and condition — newer construction or recent renovations typically adjust value upward; deferred maintenance adjusts it downward.
  • Lot and location — lot size, corner vs. interior lot, and micro-location factors within the same general market.
  • Recency — a comparable sale from last month is weighted more heavily than one from a year ago, especially in a fast-moving market.
  • Feature differences — a garage, finished basement, pool or other features present in one property but not another.

No single adjustment dominates — the model weighs all of them together, which is why two properties with similar square footage can still land in different value ranges.

Why a Range, Not a Single Number

Real estate value isn't a fixed, universally-agreed-upon number — it's the price a willing buyer and willing seller would actually agree to, which varies with timing, negotiation and individual buyer motivation. Presenting a single precise figure would overstate the model's actual precision. A range communicates the same information honestly: here's what the data supports, and here's how much uncertainty remains.

ℹ️
Confidence Levels Reflect Data Quality
A value estimate backed by five recent, closely comparable sales carries a "High" confidence label. One backed by two older or less comparable sales carries "Limited" — the same methodology, applied to thinner evidence.

What This Methodology Does Not Do

It does not replace a physical inspection or a licensed appraiser's in-person judgment, and it cannot account for interior condition issues that aren't reflected in public records or the details you provide. For financing, tax disputes, or legal matters, a licensed appraisal is required — see Why Trust Reaixo for when to use one.

Frequently Asked Questions

How does Reaixo estimate a home's value? +

Reaixo's AI-assisted model starts from recent comparable sales — homes similar in size, age, condition and location that sold recently nearby — then adjusts for the subject property's own characteristics and current local market trends to produce a value range.

Why is the estimate a range instead of one number? +

A single number implies more precision than comparable-sales-based estimation can honestly support. Two similar homes can sell for different prices depending on condition, timing, and negotiation — a range communicates that real uncertainty instead of hiding it.

What data goes into the estimate? +

Public property records, recent comparable sales (price, size, age, condition, sale date), and local market indicators such as price trends and days on market. Where you provide details — like known condition issues or recent updates — those are factored in too.

Why does my estimate differ from a public "Zestimate"-style tool? +

Different models weigh comparable sales, adjustments and market trends differently, and use different underlying data sources with different refresh schedules. No automated valuation model — Reaixo's included — is a substitute for a licensed appraisal when one is required.

What would make the confidence level "Limited"? +

Few recent comparable sales nearby, a property with unusual features that comparables don't capture well, or a fast-moving market where recent data may already be stale.
