Part 1 of 4

Why a seller cares

A material fact is anything that would change a reasonable buyer's mind or price, and in most states a seller who knows one has to say it. The test is the buyer's decision, not the seller's opinion of how serious it is.

A simple example

The roof was replaced after a hail claim, the neighbor's fence is two feet over the line, and a bedroom addition was built without a permit.

Material fact: a simple example
The factIs it material?
An unpermitted bedroom additionYes; it affects value, insurance and what the buyer can do with it
A fence two feet over the lineYes; it is a boundary question the buyer inherits
The kitchen was painted last springNo; it changes nobody's decision

If it would change what a buyer pays or whether they buy, it is material.

Part 3 of 4

What people get wrong

That material means big. A small fact can be material if it changes the buyer's decision, and a big one may not be if everyone can see it.
