Comparable data collection standardization is the practice of capturing comp facts as defined fields instead of sentences. Condition, quality, view, location, concessions, and dates each have a defined form under UAD, and free-text entry loses that form the moment it is typed. Structured capture stores what the appraiser observed and verified in a shape that can be checked, reused, and answered for later. The appraiser still selects every comparable and makes every adjustment.
What free-text comparable notes cost you later
Condition and quality arrive as adjectives
Well maintained, updated kitchen, above average build. None of it maps to a UAD condition or quality rating, so the rating gets translated from prose at report time, and two appraisers translate the same words differently.
Concessions are recorded as a sentence
Seller paid some closing costs tells you nothing usable. Type and amount are separate facts belonging in separate fields, and without them the adjustment cannot be explained to a reviewer or supported in the workfile.
Three dates collapse into one
Sold last spring hides a contract date, a settlement date, and a listing date that each drive a different part of the analysis. In a fast market the gap between contract and settlement matters most.
Source and verification are the word MLS
Which MLS, which listing number, who was spoken to, and on what date are what a reviewer asks. One word answers none of them, and by then whoever pulled the data has moved on.
Living area is a number with no standard behind it
About 2,100 square feet does not say whether finished basement area is included, what the room counts above and below grade were, or which measurement standard produced it.
Where free text breaks, and the field that replaces it
Every row is a place where prose is cheaper to type and more expensive to own. The right column is the capture we build, and none of it asks for anything the appraiser was not already collecting.
| Comp element | Typical free-text entry | What it breaks | Structured capture |
|---|---|---|---|
| Property key | 123 N Main St | Duplicates go undetected and no comp library assembles across appraisers | Parcel identifier and geocoded coordinates as the key, address kept for display |
| Condition | Well maintained, updated kitchen | Does not map to a UAD condition rating, so the rating is re-derived from prose | Condition rating from the defined set, observed features held as notes |
| Quality of construction | Above average build | Same translation problem, and no consistency between two appraisers | Quality rating from the defined set, construction detail as its own field |
| View and location | Backs onto a busy road, partial water view | UAD expects a rating plus a coded factor; prose is converted by hand | Rating and factor from the coded lists, with a note alongside, never instead |
| Sale concessions | Seller paid some closing costs | No type, no amount, nothing supportable in the workfile | Concession type and amount as separate fields, with none recorded explicitly |
| Sale type | Bank owned, sold as is | Arm’s length, REO, short sale, and relocation mean different things | Sale type from the coded list, remark attached to the code |
| Dates | Sold last spring | Contract date, settlement date, and days on market cannot be recovered | Contract date, settlement date, list date, and days on market as separate fields |
| Living area | About 2,100 square feet | Above grade and below grade finished area get mixed, and the standard is unstated | Above grade living area, below grade total and finished area, and room counts for each, to the standard the client requires |
| Data source | MLS | Which system, which record, and when it was pulled are unanswerable | Source system, record identifier, retrieval date, and the retained copy |
| Verification | Verified | The reviewer’s real question is who verified it, with whom, and when | Verification method, party spoken to, verifier, and date |
| Adjustment support | Adjusted for the extra bath | The workfile must show support, and naming the element is not support | Element adjusted, basis used, amount, and a reference to the retained analysis |
How structured comparable capture gets built
Capture at the point of observation
Comp data entered on a phone at the property, or against the listing on screen, is entered once and entered right. Data reconstructed that evening from photographs is where prose creeps back in, because prose is what memory produces.
Codes are input controls, not a cleanup pass
Condition, quality, view, location, and sale type are selected from the coded lists at entry, and every record is keyed on the parcel rather than the address. Cleaning free text into codes afterwards is a job nobody finishes.
Sources are retained, not just named
The listing sheet, deed record, or public record page is stored against the comp with its retrieval date. When a comp is questioned later, the answer is the document as it stood then, not a fresh lookup.
The comp record belongs to the office
A comp verified on one assignment is visible to the next appraiser who meets the same sale, with its source, verifier, and date. It is a starting point, not a substitute. Whether it is adequate for a new assignment is the appraiser’s call.
Pre-delivery checks look at structure only
Before a file leaves, checks flag missing required fields, unit mismatches, and inconsistent dates such as a settlement date after the effective date. They do not assess comparable selection, adjustment amounts, or the conclusion, and never question a number.
What structured comp data feeds
- custom app development for field data capture — The capture app presents the coded lists and required fields, and runs without a signal.
- document workflow automation — Retained listing sheets and public record pages are filed against the comp and into the workfile.
- form automation services — Verification calls are captured on short forms that write straight to the comp record.
Is this a fit for your business?
A good fit when
- More than one appraiser works the same market and their comp records differ
- Revision requests regularly ask where a data point came from
- You want a comp record that survives the assignment it was gathered for
- Field data is captured on paper and typed up in the evening
Probably not a fit when
- You want software that selects comparables or calculates adjustments
- You work alone, on one product, and your notes have never failed you
- You are looking for a data subscription rather than a way to keep what you gather
What to have ready
- The field sheet or checklist your appraisers use now
- Three completed reports whose comp data you consider typical
- The data sources you pull from, including the ones you pay for
Questions we get asked
Does this replace our form software?
No. It sits in front of it. The appraiser still writes the report where they write it now; what changes is that the data arriving there was captured once, in structure, at the point of observation.
Can a comparable verified last quarter be reused on a new assignment?
The record can be surfaced with its source, its verifier, and the date it was captured. Whether that is adequate for a new assignment, and whether re-verification is needed, is the appraiser’s determination. The library removes the retrieval step, not the judgment.
What happens when UAD 3.6 and the redesigned URAR arrive?
Structured capture matters more, not less, because the direction of travel is toward more defined fields and less narrative. Coded lists and required field sets are configuration here, so they change as the standard does.
Our appraisers will say this slows them down at the property.
Some of them will be right for the first few inspections. The honest trade is more structure at the property in exchange for less reconstruction afterwards, plus an answer available when a reviewer asks where a figure came from.
