>>>i dont think i will have to pay more for the 2 agents, just the one who sells it.
You DO pay more, to the one that sells it, if it is a multi agent situation.
An agent will charge you less if they know the are the sole agent (because they are guaranteed the sale).
They will charge you more if it is a multi agent as they may not get the sale.
So for example a sole agent may only charge you 1% of the sale, but if two agents are involved they may charge you 2% (though you only pay the one who sells it, but it is 2% as opposed to 1%)
