Good Condition - No obvious maintenance required but neither is everything new. Appearance and utility are above the standard and the overall effective age will be lower than the typical property.
Average condition: Some evidence of deferred maintenance and normal obsolescence with age in that a few minor repairs are needed along with some refinishing. But with all major components still functional and contributing toward an extended life expectancy, effective age and utility is standard for like properties of its class and usage.
Fair condition (Badly worn) - Much repair needed. Many items need refinishing or overhauling, deferred maintenance obvious, inadequate building utility and services all shortening the life expectancy and increasing the effective age.
Poor Condition (Worn Out) - Repair and overhaul needed on painted surfaces, roofing, plumbing, heating, numerous functional inadequacies, substandard utilities etc. (found only in extraordinary circumstances). Excessive deferred maintenance and abuse, limited value-in-use, approaching abandonment or major reconstruction, reuse or change in occupancy is imminent. Effective age is near the end of the scale regardless of the actual chronological age.
