Q:
Viola has to relocate for her job. She finds a townhome with an option to rent or buy. The conditions of each are
shown below.
Rent: Move-in costs of \( \$ 2,380 \) and monthly payment of \( \$ 845 \).
Buy: Move-in costs of \( \$ 5,260 \) and monthly payment of \( \$ 785 \).
Viola moves frequently due to her job, but she thinks that she will stay in the area for 4 years. Therefore, she decided
to buy. Choose the best evaluation of Viola's decision.
a. Since the costs would be the same over the 4 year period, she will have made a good
decision if the property value does not decrease.
b. She made a fairly good decision. Buying the townhome will be cheaper over the 4 year
period as long as she doesn't have major repairs to make.
c. She made a poor decision if the property value does not increase. Renting the townhome
would be cheaper over the 4 year period.
d. There is not enough information given to determine which option is best.
