Answer:
Yes, it will be financially advantageous to convert the land into parking lot
Step-by-step explanation:
F0 = 50,000 dollars
cash flow: 8,000 at perpetuity
present value of a perpetuity:

8,000 / 0.14 = 57,142.8571
57,124.86 - 50,000 = 7,124.86
As the value of the investment exceeds the cost it is a good idea to convert the land into parking lot.
