There are several reasons to buy a house without a realtor. First, you can save money. A real estate agent does not charge a commission to buyers, so sellers may be more likely to accept your offer. Second, you can get more information about the housing market. An agent knows the current market value of a home and can help you negotiate the price. Third, a real estate agent is not a stranger to the area. In addition, he or she can make you feel comfortable with the process.
