What you get

Four answers for every address.

The four questions that actually decide a deal. Mesa answers all of them from one address — and shows you the comparables behind each one, so you can check the work before a seller does.

Every example below uses one sample property — not a Mesa result.

01

What is it worth?

A value range built from nearby comparable sales. Every comp is listed, so you can check the work.

What does the condition cost?

Walk through the roof, HVAC, foundation and finishes. Mesa turns each issue into a dollar adjustment.

03

Is the tax bill fair?

Compare the county's assessment with what the market supports. If it's too high, Mesa drafts the protest letter.

Defensibility

Most tools hand you a number. Mesa tells you how much weight it will bear.

A value range with no provenance is a guess with a decimal point. Every Mesa valuation carries a defensibility score — seven factors, each scored zero through two, fourteen points out of fourteen — that rates the evidence behind the band, not the property. A well-built house in a thin market is still thin evidence.

  • Comparable count
  • Comparable freshness
  • Similarity filtering
  • Outlier filtering
  • Backtest accuracy
  • Assessor weighting
  • Proxy ratio
HIGH 12–14 / 14

Strong evidence. Comfortable anchoring the conversation on this band.

MEDIUM 6–11 / 14

Usable evidence. Present the band, and bring the comparables with you.

LOW 0–5 / 14

Thin evidence. Say so out loud rather than quoting a figure you cannot hold.

Thresholds are the engine's own, from defensibility.score — the same registry the tools page documents field by field.

Coverage

Real data, clearly labelled.

A county only counts once live data has come back from it — the number below is read from the engine's own dispatch tables, so it cannot drift from what the app actually resolves. Outside those counties you still get values, comparables and cost tools.

Questions

Is Mesa an appraisal?

No, and it is not trying to be. Mesa is the evidence you assemble before you call an appraiser, an inspector, a lender or an attorney — it does not replace any of them, it makes that conversation shorter and harder to bluff.

How do I know the number is real?

Every valuation carries a defensibility score: seven factors, each scored zero through two, fourteen points out of fourteen. HIGH, MEDIUM or LOW tells you how much the evidence will bear before you quote a figure, and the comparables are listed so you can check the work yourself.

What happens in a thin market?

You get told. Comparable activity drives how tight a band Mesa can produce — busy markets give tight ranges, quiet and rural markets give wide ones or none. The defensibility score falls with the data, so thin evidence reads as thin rather than as false precision.

Does it work for commercial property?

Not yet. Mesa covers residential single-family and multi-family homes.

How much is it?

One paid tier, sold as a one-time annual licence key, with the current price shown at checkout. Keys are issued by email and there is no auto-renewal — if it earns its place in your workflow, you buy it again; if it does not, you have lost the key, not a subscription.

Which platforms is it on?

Windows first, as a desktop application. macOS follows once Apple developer notarisation clears. Mesa is in pre-alpha and the feature set is still moving.

Is my data private?

Yes. Mesa never sells your data. Addresses you enter are only used to build your report.
