What is the most comprehensive option for costs associated with renting an apartment?

The most comprehensive option for costs associated with renting an apartment is the choice that includes first and last month's rent, furnishings, the security deposit, and any additional relevant costs. Renting an apartment typically involves several expenses beyond just the monthly rent. The first and last month's rent ensures that the landlord has financial security both at the start and the end of the lease. A security deposit is commonly required to protect the landlord against potential damages or unpaid rent. Furnishings, while sometimes not mandatory, can significantly impact costs depending on whether the apartment is furnished or unfurnished. By including all these elements, the chosen answer captures the full scope of potential financial obligations when renting an apartment, providing a realistic view of what a tenant should anticipate while budgeting for their living situation.
