One is the possibility of having mutually negotiated fees. This can also be beneficial as prices increase every year in business. Additionally, another advantage of the options is the ability to have a single contractor to complete the entire project, which helps keep everything organized and simple. Additionally, the profit margin would be more economical due to having a single supplier rather than multiple suppliers. The disadvantages of options are that if there are no funds for the option years, then the purchase agreement is useless. Which means a waste of money and paper. Another disadvantage is that if in the future the cost would be cheaper than the price of the agreed option. Additionally, by not being able to fulfill your part of the agreement, it would create an unpleasant experience with the contractor, which could harm any future.
