Realtor commission on multi family

[Kaleena Felipe]

I am in negotiations of purchasing a 4 plex to house hack. Is it typical that developers do not pay realtor commissions to a realtor who is personally buying the property? The developer has agreed to pay 1% commission to me or a upgrade package of grass, garage door openers and a small extended slab? Should I negotiate for a larger commission? He originally said it would be 2% on a 560,000 purchase price.
