Hello
Agents usally charge a percentage of the selling price.. which they only get if the contract is accepted and goes to closeing.. so in other words you only pay if you end up buying it.. but what makes it better is that they usally get the money from the seller.. So an agent working on your behalf will split the commision of the selling agent... So you end up paying almost nothing.. to the agent.. maybe a 2hundred and somthing dollar admin fee..
Let me know if you need any more help.. I am an agent by the way..
