Final answer:
To calculate the initial cash flow for the building project, subtract the current value of the lot from the total costs.
Step-by-step explanation:
To calculate the initial cash flow for the building project, we need to consider the costs and the current value of the lot. The costs include the purchase price of the lot ($690,000), the grading cost ($35,000), and the building cost ($1,260,000). The current value of the lot is $747,000. To calculate the initial cash flow, subtract the current value of the lot from the total costs:
Initial Cash Flow = Total Costs - Current Value of the Lot
Initial Cash Flow = $2,015,000 - $747,000
Initial Cash Flow = $1,268,000
Therefore, the correct answer is $1,268,000.
