In selling a home is more difficult than selling anything especially if you have no idea how to deal with this kind of transaction. If you are selling your home alone you can sell it in your own price and once you received the payment, that whole amount will be yours.
If you will ask the real estate agent to sell your home, you need to pay them 5% of the total selling price of your home other agents sell your home at a higher price than your original price. They will give you only the original price you want to be sold and their additional price will go into their pockets aside from the 5% payment that you need to pay for them as their commission. The real estate agent has a lot knowledge on true value of home, but nowadays buyers don’t buy a home from agents anymore because they know already the style of the agents in selling a home.
