The JustValue Review Standard

Every JustValue conclusion should be checkable. This page explains what we review, the evidence we accept, how we reach a conclusion, and the reasons we decline a case. It is the standard our own guarantee is measured against.

What we review

JustValue analyzes public records: the county tax roll, property characteristics maintained by the county Property Appraiser, and recorded sales. We review every eligible single-family home and condominium in a covered county — not a sample. We use no private data, and nothing about a property's owner beyond what the public record contains.

The evidence we accept

An assessment review is only as strong as the sales behind it. Our standard for a comparable sale:

Qualified, arm's-length, single-parcel sales only, as classified by the state's own sale-qualification codes. Multi-parcel and allocated sales are excluded — a price covering two properties is not evidence of one property's value.
Sales from the year preceding the assessment date. Florida assesses value as of January 1. Our primary evidence window is the calendar year before that date — the same sales the county's own methodology draws on. When a neighborhood has few qualified sales, we extend the window earlier, never later: sales after the assessment date are not primary evidence of value on it.
Genuinely similar properties. Comparables must match the subject's property-use class and be evaluated on the characteristics the county itself records: location (nearest first — same subdivision or neighborhood before wider areas), heated living area, age, and configuration where the county publishes it. Condominium units are compared against sales in their own complex.

How we reach a value conclusion

We compare price per heated square foot across the most similar qualified sales — typically five to eight — weighted by similarity, and take the middle of that evidence, not its edges. We never build a case on the lowest sale we can find. A conclusion supported by the center of the evidence is one that holds up; an outlier is an argument waiting to lose.

Every review receives an evidence-strength rating based on how many qualified comparables exist, how similar they are, and how tightly they agree. Weak evidence is labeled as weak. When the evidence does not support review, the result says so — a fair assessment is a valid result, and we say it plainly.

The completeness rule

We do not produce a valuation from an incomplete record. If required characteristics are missing for a property — or for the sales it would be compared against — the result is “needs additional review,” not a guess. We would rather tell you we're not ready than sell you a case we can't stand behind.

Exemption and portability findings

Homestead and portability findings describe the public record, not eligibility. “No homestead on record” means exactly that; whether an owner qualifies is attested by the owner and decided by the county. Estimated exemption savings are computed from each county's verified millage, including the school-tax portion the second exemption does not apply to — a detail often overstated elsewhere. Where a county's millage components are not yet verified, we show no figure rather than an approximate one.

Reasons we decline a case

Under our guarantee, a paid case that fails final review is refunded in full. The reasons a case can fail:

Too few qualified comparable sales after all window and area extensions
Required property or comparable characteristics missing from the record
Assessment-cap circumstances that make the apparent difference unactionable
Updated county values that no longer support the original finding

What our review is not

A JustValue review is an automated analysis of public records with human quality confirmation on irreversible steps. It is not a licensed real estate appraisal, legal advice, or a prediction of any county decision. The AI-REVIEWED mark on an analysis means it passed our quality-control standard — it is not a certification or a guarantee of outcome. Property owners may appeal assessments and apply for exemptions directly with the county at no charge, without purchasing anything from JustValue.
