A) The mortgage principal and interest payment - This does not depend on the owner's home value. These depend on the loan amount borrowed from the bank. The monthly payments will be the same irrespective of the owner's home value being going up or down.
B) The local property tax - This is the right answer as the local taxes depend on the prices in the area or neighborhood. Like posh areas have high property taxes.
C) The mortgage interest rate - This is not right. This depends on the bank that how much interest rate it will give you depending on your credit history.
D) The cost of utilities such as heating and electricity - This is also not right as these costs are standard for a state. Everyone will have the same per unit rates for electricity.
