The Uniform Appraisal Dataset (UAD) format, required by Fannie Mae and Freddie Mac since September 1st, 2011, includes a new standardized system for entering the Condition of comps in your sales grid.
Previously, comparable Condition was entered relative to the subject; under the new system, Condition is measured using rankings from 1 to 6, detailed below. You may want to bookmark this article or print it for your reference.
C1: The improvements have been very recently constructed and have not previously been occupied. The entire structure and all components are new and the dwelling features no physical depreciation.
Note: Newly constructed improvements that feature recycled materials and/or components can be considered new dwellings provided that the dwelling is placed on a 100% new foundation and the recycled materials and the recycled components have been rehabilitated/re-manufactured into like-new condition. Recently constructed improvements that have not been previously occupied are not considered “new” if they have any significant physical depreciation (i.e., newly constructed dwellings that have been vacant for an extended period of time without adequate maintenance or upkeep).
C2: The improvements feature no deferred maintenance, little or no physical depreciation, and require no repairs. Virtually all building components are new or have been recently repaired, refinished, or rehabilitated. All outdated components and finishes have been updated and/or replaced with components that meet current standards. Dwellings in this category either are almost new or have been recently completely renovated and are similar in condition to new construction.
C3: The improvements are well maintained and feature limited physical depreciation due to normal wear and tear. Some components, but not every major building component, may be updated or recently rehabilitated. The structure has been well maintained.
C4: The improvements feature some minor deferred maintenance and physical deterioration due to normal wear and tear. The dwelling has been adequately maintained and requires only minimal repairs to building components/mechanical systems and cosmetic repairs. All major building components have been adequately maintained and are functionally adequate.
C5: The improvements feature obvious deferred maintenance and are in need of some significant repairs. Some building components need repairs, rehabilitation, or updating. The functional utility and overall livability is somewhat diminished due to condition, but the dwelling remains useable and functional as a residence.
C6: The improvements have substantial damage or deferred maintenance with deficiencies or defects that are severe enough to affect the safety, soundness, or structural integrity of the improvements. The improvements are in need of substantial repairs and rehabilitation, including many or most major components.
