In which scenario would you find equity being calculated?

Equity represents the ownership interest that a homeowner has in their property, which is calculated as the current market value of the property minus any outstanding liens or mortgages. In the context of real estate, equity is essential for understanding a homeowner's financial stake and can influence various transactions, such as refinancing, selling, or accessing home equity loans.

In scenario C, calculating equity involves assessing how much of the home the homeowner truly owns after accounting for debts against the property. This assessment is not only crucial for the homeowner but also plays a significant role in potential buyers or lenders evaluating the property.

The other scenarios primarily address different financial calculations or assessments that do not directly relate to a homeowner's equity. For example, property assessments focus on taxation rather than ownership interest, commission splits deal with the division of earned income between agents, and proration of closing costs pertains to allocating expenses rather than evaluating ownership stake. Thus, the calculation of equity specifically pertains to understanding a homeowner's financial interest in the property, making it the correct choice.
