the FirstPaymentDate properties should be the same value/source.

Perhaps reading Allen Holub discuss why Getters and Setters are Evil[^] will help you.

How do I define IBaseObject to imply that the FirstPaymentDate property is the same in both the IBaseObject definition and the ICalculatable definition?
