Abstract

Automatically rating appraisal quality and evaluating comparables listed on the appraisal. A comparable selection model selects control comparables using transaction data and property characteristics relative to a subject from a database. An evaluation model compares the control comparables to the listed comparables to generate a quality rating for the appraisal based on category scores that result from an appraisal evaluation over a set of categories.

Claims

1. A method for an automatic quality rating of appraisal selected comparables, comprising:

creating a comparable list by;

selecting by a comparable selection model control comparables based on a subject, and

adding the appraisal selected comparables to the control comparables;

ranking the comparable list using category comparisons; and

displaying the ranked list via a display device.

2. The method of claim 1, wherein the comparable selection model selects the set of control comparables using transaction data and property characteristics relative to the subject.

3. The method of claim 1, wherein ranking the comparable list using category comparisons, comprises:

generating for each comparable in the comparable list set of scores where each score is relative to a category in a category set,

wherein the category set includes comparable selection, comparable adjustment, comparable weighting, and final valuation.

4. The method of claim 3, wherein generating the category score for the comparable selection category is based on how closely the control comparables and the appraisal selected comparables match in terms of explanatory variables.

5. The method of claim 4, wherein the explanatory variables include property characteristics, distance from subject, age of comparable sale, price distribution, and rank ordering.

6. The method of claim 3, wherein generating the category score for the comparable adjustment category is based on the difference between adjustments made to the appraisal selected comparables and adjustments made by the comparable selection model to the control comparables.

7. The method of claim 3, wherein generating the category score for the comparable weighting category is based on a comparison of

a weighting of each appraisal selected comparable based on how closely each appraisal selected comparable matches an appraisal valuation to

a weighting of each control comparable based on how closely each control comparable matches the appraisal valuation.

8. The method of claim 3, wherein generating the category value for the final valuation category is based on how closely

a final valuation of the subject by the appraisal using the appraisal selected comparables matches

a final valuation of the subject by the comparable selection model using the control comparables.

9. The method of claim 1, further comprising:

automatically rating a quality of each appraisal in a set of appraisals,

wherein each appraisal of the set of appraisals is segregated based on its respective quality rating into groups, and

wherein the segregating is based on the automatic quality rating of appraisal selected comparables.

10. The method of claim 1, wherein the display device is selected from a set of display devices that includes a light-emitting diode display, a liquid crystal display, an organic light-emitting diode display, a plasma display, and a cathode-ray display.

11. The method of claim 1, wherein the display device is connected to an electronic device,

wherein electronic device is selected from a set of electronic devices that includes personal computers, laptop personal computers, mobile phones, smart-phones, super-phones, tablet personal computers, and personal digital organizers.

12. A computer program product stored on a non-transitory computer readable medium that when executed by a computer performs a method for automatically rating a quality of an appraisal, the method comprising:

creating a comparable list by;

selecting by a comparable selection model control comparables based on a subject, and

adding the appraisal selected comparables to the control comparables;

ranking, by the computer, the comparable list using category comparisons; and

displaying the ranked list via a display device.

13. A method for an automatic quality rating of appraisal selected comparables, comprising:

means for creating a comparable list by;

selecting by a comparable selection model control comparables based on a subject, and

adding the appraisal selected comparables to the control comparables;

means for ranking the comparable list using category comparisons; and

displaying the ranked list via a display device.

14. An apparatus that automatically rates a quality of appraisal selected comparables, comprising:

a circuit that creates a comparable list by selecting control comparables based on a subject via a comparable selection model, extracting the appraisal selected comparables from an appraisal, and adding the appraisal selected comparables to the control comparables, and that ranks the comparable list using category comparisons; and

a display that displays the ranked list.

15. A method for rendering an appraisal scorecard, comprising:

receiving an appraisal;

executing a data integrity check on the appraisal;

evaluating the appraisal if the appraisal passes the data integrity check by running the appraisal through a comparable selection model and a value confidence model; and

rating the appraisal based on the appraisal evaluation and pass/fail thresholds,

wherein evaluating the appraisal includes generating for each comparable identified by the comparable selection model and the value confidence model scores that are relative to a category set, which includes comparable selection, comparable adjustment, comparable weighting, and final valuation.
