appropriate registers and go to step 12.
Example: You are being transferred for 4 years to a distant city and are faced
with the decision of whether to rent or to buy a house. A quick survey of the
housing market indicates that you can purchase an acceptable house for $70,000
with a $7,000 down payment on a 30 year mortgage at 12% interest. The closing
costs would be about $1200. Selling costs include a 6% commission for resale
and miscellaneous other fees that amount to another 2% of the sale price.
Housing in the area is appreciating 10% per year. Property taxes would be about
$110 per month, and you estimate that maintenance would cost an additional $65
per month.

The user should key in the total marginal income tax – Federal plus State – to obtain
calculations which reflect the tax advantages of home ownership. Because of the
complexities of tax laws and different financial and tax considerations for each individual,
this program should only serve as a guide in considering an investment of this type. For more
specific, detailed information, consult a tax accountant or qualified tax advisor.
6.
If the calculator displays a negative result or Error 5 when solving for yield then your
investment has resulted in a loss. The amount of interest earned on the alternative investment
is not taken into account in this calculation.
