yea,

but there is not much deal like this, and they are not representative in any case. If you involve few agencies and all of them want their share, price for buyer must be higher, higher price bring less demand, and in the end we all lose.
There is no set rules as they are in countres which have real estate business developed in last 200 years.
And I think they will rather consider Remax over domestic, because they have different standard of doing business and here is just to much people involved spoiling real efforts.
