A capitalized cost was computed to be $600,000. The structure includes some additional expenses of $35,000 at the BEGINNING of each year for the next 15 years, a renewal cost of $100,000 would occur in which the expected life of the structure is 5 years to begin at the end of 10 years. Another cost to consider starting at the end of the 10 th year for 20 years, is expected amounting to $5,000. If interest rate is 8% per year, determine the perpetual maintenance of the structure.
