What do you mean by buyer agent's rebate?

If your house sells for $200K you need to pay for 200K * 0.05= 10000 plus state tax on top of $10K which is another 700-1000. That is all you need to pay for both seller and buyer agent. each agent takes 5000. After the agent takes their share of $5000 they are required to pay their share of income tax at the end of year as well as their fees to whichever realstate agency they belong too.Most buyer agent will give some kick back for their buyers and contribute to their buyer's closing cost. That way they dont need to pay tax for that part. Depends on the cost of the house, the kick back would be different.
