Section 12: Real Estate and Lending 131
An alternative would be to rent a similar dwelling at $400 per month and to
invest the difference between the purchase cost and rent at 6¼% interest. Your
personal income tax rate (marginal) is 25% Federal and 5% State. Which
alternative is more financially attractive?
By purchasing a house, you would gain $10,858.08 (32,391.87 – 21,533.79) over
an alternate investment at 6.25% interest.
Deferred Annuities
Sometimes transactions are established where payments do not begin for a
specified number of periods; the payments are deferred. The technique for
calculating NPV may be applied assuming zero for the first cash flow. Refer to
pages 59 through 63.
Example 1: You have just inherited $20,000 and wish to put some of it aside for
your daughter’s college education. You estimate that when she is of college age,
9 years from now, she will need $7,000 at the beginning of each year for 4 years
for college tuition and expenses. You wish to establish a fund which earns 6%
annually. How much do you need to deposit in the fund today to meet your
daughter’s educational expenses?
