Answer:
C. Because fewer people may be willing to purchase a home in the area
Step-by-step explanation:
Property taxes is the amount of money that people have to pay annually to the government if they want to own a property (such as a house or office building, etc).
Increasing property taxes means that there will be lesser people who can afford to own property in that area.
This will create a shortage of demand for properties in that area. Since realtors are the one that built and sell those properties, they profit will most likely decreased when the property taxes raise.
