The Rent or Buy Decision

The question of whether to rent or purchase a residence is not always easy to
answer, especially when the time period over which you would own or rent a
house is short. This program (written in RPN mode) performs an analysis which
could be helpful in reaching a decision. Essentially, it calculates a yield or rate of
return on the proposed investment. This yield may be compared with the yield
obtained by renting a residence and investing the down payment and monthly
payment differences in a savings account or other investment opportunity. This
program takes into account the tax advantages obtained by a home owner on
property taxes and mortgage interest.
First the program computes the Net Cash Proceeds upon Resale (NCPR),
the yield on the investment in the house and then the value of the hypothetical
savings account at the end of the investment period. A comparison of the NCPR
and the final balance of the savings account and a comparison of the yields
should aid in determining whether to rent or buy.

The Net Cash Proceeds upon Resale (NCPR = sales price – commission – mortgage
balance), is the pre-tax proceeds. The program assumes that the buyer reinvests in like
property and is not subject to capital gains tax.
