External obsolescence

Loss of value from something outside the property: a new highway next door, a shuttered factory in view, a rough patch in the surrounding neighborhood. Hard to fix.

Part 1 of 4

Why a seller cares

A highway, a power line or a shuttered plant next door lowers value and nothing you do to the house changes it. Pricing has to start from comps that share the same neighbor.

Part 2 of 4

A simple example

Your home backs onto a four-lane road. Homes two streets in sell for $320,000; the ones on your street sell for about $290,000.

External obsolescence: a simple example
The compWhy it does or does not fit
Two streets in, $320,000Wrong; it does not share the road
Same street, $290,000Right; the road is priced into it
A new fence and landscapingHelps the photos; does not move the road

External obsolescence is outside the fence, and so is the fix.

Part 3 of 4

What people get wrong

That improvements can offset it. They can make a home the nicest on the road; they cannot make the road go away.
