Part 1 of 4

Why a seller cares

It is the legal reason your agent has to put your interest first: loyalty, confidentiality, full disclosure, obedience, accounting. It is also the thing a transaction broker or a dual agent does not owe you.

Part 2 of 4

A simple example

You tell your agent you would take $290,000. Under fiduciary duty they keep that to themselves; a transaction broker may not be bound the same way.

Fiduciary duty: a simple example
The dutyWhat it looks like
LoyaltyYour price, not their commission, drives the advice
ConfidentialityYour bottom line stays yours
DisclosureThey tell you what they know that affects the deal

Fiduciary duty is the difference between an agent and a helpful person with a license.

Part 3 of 4

What people get wrong

That every licensed person in the deal owes it to you. Only your own agent does; the buyer's agent owes it to the buyer.
