Abstract

This program permits the financial analysis of a real estate investment project under a variety of assumptions concerning financing, tax treatment, and holding period. Government subsidies can also be included in analyzing projects which use subsidy provisions such as those of the 1968 Housing Act. The program yields the rate of return of the investment, and the cost of the government subsidies. In addition, the investor can obtain the balance, income, and cash flow statements, or a compact summary of the financial life of the project.

Government subsidies can also be included in analyzing projects which use subsidy provisions such as those of the 1968 Housing Act. The program yields the rate of return of the investment, and the cost of the government subsidies. In addition, the investor can obtain the balance, income, and cash flow statements, or a compact summary of the financial life of the project.

The program is written in APL, and has an input phase shown in flowchart A, and an execution phase shown in flowchart B. One essential feature of the program is that it provides different "levels" of input and output for users with different degrees of familiarity with computing in general and APL in particular. For example, during the input phase a user can use the fully conversational level by simply following step by step instructions provided by the computer. At the other extreme, he can enter data using APL instructions. In any case, the input phase permits the selection of about thirty-five parameters which affect the project.

Execution is called by the "Go" function which contains three sub-routines: "Initialize", "Interrelate" and "Run". The subroutine "Initialize" sets the variables of the program according to the specifications of the input phase. The subroutine "Interrelate" provide...
