It's a mix. I do both as a broker. This would be better suited for the commercial section about halfway down.
That usually means say you listed land at 10 percent for a 1,000,000.
You sold it for 1,000,000 for full asking. 10 percent is 100,000 BUT WAIT there was a 5 percent co-op to the selling broker. So when it closed your brokerages cut was 5 percent or 50,000.
Of that according to you is split 50/50 so in that case you would get a gross check for 25,000 and your broker would get 25,000.
This of course does not include any franchise fees,etc. Those would need to be disclosed on your IC agreement. Don't take things people tell you as the truth. Read your IC agreement and their policy and procedures manual.
There are many niches to commercial. Networking is key so if you have no experience 25,000 from 50,000 is better than spinning your wheels and getting 0 from 0.
After you have gained experience you can renegotiate.Commercial real estate is extremely complex more so than residential.
good luck
