Effective age

An appraiser's estimate of how old a home functions and looks, given upkeep and updates. A well-maintained 1950s home can have an effective age much younger than its real age.

Part 1 of 4

Why a seller cares

The appraiser's effective age is how old the home acts, not how old it is, and updates lower it. It is one way a renovated 1950s home appraises alongside newer ones.

Part 2 of 4

A simple example

A 1955 home with a new roof, new kitchen and baths, new windows and updated systems. The appraiser assigns an effective age of about 15 years.

Effective age: a simple example
The homeActual age and effective age
1955, fully updated70 and about 15
1955, original everything70 and 70, or worse
2005, never maintained20 and maybe 35

Effective age is what maintenance buys you in the appraisal.

What people get wrong

That an old house is an old house. Appraisers separate the year from the condition, and condition is the one you control.
