Scaling commission to expensive homes

[Jason M.]

I'm looking at buying my first home that I plan to live in.  I've bought 8 homes so far that were purchased with the purpose of renting out to other tenants.  So, I have some experience.

The rental properties cost around $100k each. I ended up negotiating to 2% buyers agent commission since I was buying a bunch of properties and wasn't using much of the agent's time.

For my home purchase, I'm looking at homes that are 2-3 million dollars.  Paying $90,000 (3%) to a buy-side broker seems insane.  Especially since I'm not even using a lot of their time.  I look for the homes I like myself on zillow and redfin.

What's a reasonable rate to pay a buy-side broker on a home this expensive?
