@Jace Holt you nailed it on the head. In residential brokers want buyers to have separate agents.
It’s tough bc if you bring in another broker on larger multifamily, the guys who list everything just stop wanting to bring you off market deals or even see to it that you get the deal bc outside brokers who are incompetent bring unknown risk into a listing agent’s process for their seller. So a good work around is if you REALLY like an agent and want them to represent you but you don’t want to stop getting deals you can build in a finders fee for your Buyside broker to be paid at closing out of your side of the deal (not seller’s side like a broker co op). This way, you still see deals, but you have someone giving you white glove service and do all your misc real estate things.
Or, if you like certain listing agents just work with them direct and on other deals you don’t like the listing agent bring another agent in and pay him yourself 1% (just factor into your offer price) to do everything for you. It also depends on who finds who. If a listing agent calls you, he implies he wants to rep you. If you have a broker looking and finds another broker’s listing from an advertisement, that’s different, of course. Then the listing agent will probably cooperate on and pay him out of seller proceeds.
If a broker brings YOU a deal and you say “I have an agent who handles everything for me, please pay him half.” You run the risk of the broker moving you down on his buyer list and even potentially not wanting to work with you again, like I said this is different from residential
