PREFACE
ABOUT THIS MANUAL
You will notice that this manual is concise. This is intentional
as we strived to make Mortgage Designer the easiest program of its
type to use. We opted to provide an extensive built-in user help
system. Feel free to use this reference manual to install and
get acquainted with the program.
For many of you, this may be your first exposure to Shareware.
To help eliminate possible confusion, we included a short
description of the Shareware marketing concept, explaining what
it is and why it relies on YOU for its survival.
WHAT IS SHAREWARE?
Shareware is not a kind of software. It is a revolutionary
method of marketing Commercial software. Our software is
Commercial software that we are allowing you to examine for 15
days before you make the purchase decision. With traditional
marketing methods, you have to purchase Commercial software from
a computer store or through mail order businesses, then try it
out, and hope it does what you want. Shareware allows you to
"try before you buy!"
We rely upon you, the customer, to examine our software. If you
find it useful, please register. Your support is needed for us
to continue to improve our products.
With warmest regards,
David Black
President, MaeDae Enterprises

WHAT IS MORTGAGE DESIGNER?
==========================
Mortgage Designer is a powerful and easy to use mortgage package
for Windows 3.x that allows you to:
1. Quickly calculate mortgage repayment information,
2. Generate amortization schedules for output to the screen,
printer, or file, with the flexibility of choosing which payments
are shown,
3. Perform complex "What if?" calculations where the principal,
interest rate, term, or payment can be adjusted,
4. And do it all without cryptic commands! Windows even makes it
fun!

(C) Copyright 1991-1993 MaeDae Enterprises
HARDWARE REQUIREMENTS
=====================
1. IBM PC/AT, IBM PS/2, or fully compatible computer capable
of running Windows 3.0 or later.
2. At least one 5.25" or 3.5" floppy disk drive. Two floppy disk
drives or one floppy and a hard disk (400K free space minimum for
the full system) are strongly recommended.
INSTALLATION - README.DOC
=========================
For all installation information see the README.DOC on the main
distribution diskette. You can view the information on-line or
print it out on your printer. README.DOC is constantly updated
to contain the latest information.
P.S. The Shareware version of Mortgage Designer is complete.
However, it is a 15 day trial version. Also, additional product
information screens have been added.
Feel free to share ONLY the Shareware version with friends and
potential users of Mortgage Designer for 15 day trial/evaluation
purposes only. You may not use the Shareware version on other
machines in order to avoid purchasing additional copies of the
full program. You may not give away any copies or make more than
one copy of the fully operational program for other than archival
purposes. The full version of Mortgage Designer has a unique
serial number embedded in each copy for traceability.

IMPORTANT INSTALLATION NOTES:
1. Diskette #1 contains many files in addition to MD.EXE.
Please make sure these files are all installed in the same
directory when running the program.
2. If Mortgage Designer does not run properly:
A. Your machine may not be 100% IBM PC operating system
compatible or Windows may be installed incorrectly. This
is not always disastrous and a quick call to our phone
support staff may solve your problem.
B. You may have a slightly incompatible Windows video
driver. Usually, updating your driver or re-installing
Windows solves the problem.
C. If you have any memory resident programs or system
drivers, try running without them loaded on your computer.
3. This manual is designed to give you a general overview and
familiarity with the program. More complete, up-to-date
information is available to you through the extensive built-in
user help (F1) system or the help button when available on dialog
boxes. When using the more advanced features of the program, the
help screens will guide you through the toughest questions with
ease. As Mortgage Designer continues to add more features, you can
be sure that the built in help will give you the guidance needed.
This way everybody wins. We don't spend money continually
revising manuals and charging you higher prices. You get what
you want and deserve: accurate, up-to-date information. So fire
up the computer, dig in, and welcome to Mortgage Designer!

GETTING STARTED
===============
After you run MD.EXE using the file manager, the MAIN MENU will
appear on your screen.
The Main Menu options with descriptions are below.
*File: This menu option provides the preferences area that
allows the basic data editing option for selecting the mortgage
info you want to work with. This option also provides access to
the database for saving the mortgage information as the default
which is to be used each time you run Mortgage Designer.
Note: You must first tell Mortgage Designer the specifics of the
mortgage before you can use the other sections of Mortgage Designer.
*Calculate: Allows you to calculate the remaining balance, cost
of loan, and pay "What If?" to solve for missing information.
*Reports: Generate amortization schedules and compare mortgage
options.
*Tax Time: Calculates the distribution of your payments divided
into yearly principal and interest totals. This should be very
useful at tax time. It will also estimate your yearly tax
savings due to interest paid on the mortgage. Use these figures
as rough estimates only since each person's tax situation is
normally very different.
*Help: Provides the help index/commands, invoice printing, and
information about the version of Mortgage Designer.

TUTORIAL (CALCULATING A MORTGAGE)
=================================
Now let's do something simple to demonstrate how Mortgage Designer
works.
Choose the File menu option. Then pick the Edit option from the
menu. A dialog box will appear allowing you to edit the
information concerning the mortgage. Use your mouse and click on
the edit field containing the principal amount. You may also
select the principal edit field by pressing Alt+P (the P is
underlined, so Alt plus the underlined key will select it).
For our sample mortgage edit each field to contain the following:
Principal: 100000.00
Interest rate: 10.000
Term: 30 years
After you alter the edit fields to contain the above information,
select the payment button. A dialog box will pop up showing that
the payment is $877.57 per month. Thats all there is to it.
Select OK then select the done button and we're finished.
Note: If you normally work with a certain principal, interest
rate, or term, use the database option to save the information as
defaults for Mortgage Designer. They will be added to LoanData.INI
and automatically loaded each time you run Mortgage Designer (if
specified as the default).
Page 9
(C) Copyright 1991-1993 MaeDae Enterprises
USING "WHAT IF?" CALCULATIONS
=============================
Mortgage Designer supports calculating the missing item from
principal, interest rate, term, and payment. Any missing item
can be calculated given the other three.
When using the missing variable area under the calculate
pulldown, you enter the information you know. Mortgage Designer
will calculate the missing item. Tell Mortgage Designer which item
is missing by checking the radio button for the missing data
item. Then select the calculate button to calculate the missing
item.
You will notice that as you solve for different items, the basic
mortgage information will change slightly. Example: Use the
data from our tutorial on the previous page and solve for the
principal. The principal will be changed from 100000.00 to
99999.82. The difference of 18 cents is caused by the rounding
of the math.
The term in years has the most granularity. Since we can only
have whole years, it is extremely hard to accurately handle this
area. Mortgage Designer rounds to the nearest whole year. After
you solve for year, we recommend you perform a second calculation
solving for a second area. We might first solve for the term,
then solve for the payment to allow Mortgage Designer to compensate
for the granularity of the years.
As you run through the mortgage what if calculations, consider a
15 year mortgage verses a 30 year mortgage. The payments are not
twice as high! They are only a little higher and you reap huge
savings over the life of a mortgage. (You can use the calculate
cost of loan section of Mortgage Designer to obtain the total
cost of a mortgage over its lifetime.)
Page 10
(C) Copyright 1991-1993 MaeDae Enterprises
TROUBLESHOOTING
===============
If Mortgage Designer will not run, you may have insufficient memory
or too many memory resident programs. Try running Mortgage
Designer with no memory resident programs or allocate a larger
swapfile under Windows. See your Windows User's Guide for help
with the Swapfile program.
If Mortgage Designer just stops running and you get an
"Unrecoverable Application Error," you may have incompatible
hardware/software. Try running Mortgage Designer in the 386
Enhanced mode (if you have a 386 computer) to see if that
corrects the problem.
Occasionally, certain memory resident TSR or "pop-up" programs
conflict with Mortgage Designer. In general, there is no problem,
but there are many new programs being written without regard to
the system requirements of other programs that may be running at
the same time. Remove them from memory, and try again. If that
fails, try getting rid of device drivers in your CONFIG.SYS file.
Invalid values for the principal, interest rate, or term can
create math problems. Invalid values used in the math
calculations can result in Mortgage Designer failing to run
correctly. If this occurs AND you have saved the values as
the default, delete LoanData.INI and then rerun Mortgage Designer.

BASIC DEFINITIONS:
==================
The terms used in Mortgage Designer may be a little confusing.
They are terms frequently used when discussing mortgages. We
have defined the most important ones for you in the definitions
listed below. They are:
Amortization schedule - A report showing each period during a
mortgage with information on how much went to principal/interest
and the loan balance.
Interest Rate - The cost of the mortgage expressed as the percent
per year. The rate of repayment for money being borrowed.
Payment - The amount of money to be repaid per repayment period.
Principal - The amount of money being borrowed or loaned out.
Term - How long is the money being borrowed or loaned out.
Page 12
(C) Copyright 1991-1993 MaeDae Enterprises
MORTGAGE DESIGNER LIMITS
========================
The limitations on accuracy for built-in math causes Mortgage
Designer to place limits on the range of data you can enter.
Listed below are the most important areas:
Principal - $100.00 to $999,999,999.99
Interest rate - 0.100% to 50.000%
Term - 1 to 50 years
Payments - $1.00 to $999,999,999.99 per period
Mortgage start date - MM/DD/YYYY where month is 1-12, day is
normal day of month, and year ranges from 1900 to 2100
Notes:
1. Mortgage Designer uses double length floating point numbers for
its calculations. This means Mortgage Designer will be more
accurate than many of the figures from banks and financial
institutions. However, even double length floating point numbers
have a limit on their accuracy. Because of these limits, the
values for principal, interest, term, and payment used by
Mortgage Designer have built-in checks to ensure they are limited
so the calculations are accurate.
2. The above limits are imposed to ensure the accuracy of
answers and should not limit users in solving mortgage
calculations. However, we do want to be receptive to your needs.
If any of the limits need to be adjusted, please let us know.
3. Database - No limits except for minor performance slowdown
with exceptionally large databases.

ADDITIONAL INFORMATION
======================
The information listed below is provided in an effort to aid you
in working with Mortgage Designer and understanding the mortgage
calculation process.
Before you can use Mortgage Designer you have to define the problem
to be solved. Get all the facts you need to solve the problem.
If you do not have the principal, interest rate, or term then
use the calculate missing variable area of Mortgage Designer to
obtain this information.
After you have defined the problem and start using Mortgage
Designer you may notice that numbers you enter are changed
slightly. This is because pure numbers used by computers do not
contain commas, dollar signs, etc. Because of the limitations of
number conversions, Mortgage Designer works in the background to
constantly strip out invalid characters. This is transparent to
you unless the "cleaned up" number is invalid. Then you will be
notified of the problem.

WHATSNEW.DOC
Mortgage Designer v2.00 for Windows provides the following over v1.40:
- Added a command/icon bar for easy execution of common commands.
- Added a status line complete with date and time.
- Now you can use F1 access from all points in Mortgage Designer
(even message boxes).
- Mortgage Designer limits have been greatly extended on principal
(from $500,000,000.00 to $999,999,999.99), interest rate (from
25.000% to 50.00%), and term (from 30 years to 50 years). Extensive
checks are now performed during math calculations to inform you if
your mortgage is too complex to calculate.
- Greatly expanded the error checking to validate values in as many
places as possible. The "What if?", refinance, variable rate mortgage,
and PITI areas now validate all numbers when you exit each of the
areas. Each of these areas have a built-in memory to retain your
last values between uses.
- Expanded the built-in help adding hints on how to get more out of
Mortgage Designer.
- Combined the preferences and loan database areas. The preferences
area can now provide customized loan information, tax brackets, PITI
defaults, and more on each loan (record) in the database. This
really allows you to customize Mortgage Designer.
- Expanded the database area to provide easier selection of records.
- Expanded the about Mortgage Designer box to provide free memory,
operating mode, and co-processor status information.
- Expanded all calculations to handle 3 decimals on interest rates.
Several users have asked to be able to handle 1/8 percent (0.125)
rate increments.
- Rewrote the mortgage amortization area to provide additional features
that several users had requested.
- Rewrote the mortgage comparisons area to use a listbox and provided a
print option for it.
- Numerous minor additions users had requested.
- Do you have suggestions for improving Mortgage Designer? Please fill
out the SUGGEST.DOC form and send it to us. We would like to hear
from you.
Mortgage Designer v2.01 for Windows provides the following over v2.00:
- Touched up the help icon on the tool bar to be easier to read.
- Corrected a minor problem with the cursor when using the Show
Comparisons function.
Mortgage Designer v2.02 for Windows provides the following over v2.01:
- Touched up the location of some of the buttons on the dialog boxes.
- The amortization screen now has a final payment button that calculates
the last mortgage payment. This function uses the normal payment and
the remaining balance at the end of the amortization period to calculate
an adjusted last mortgage payment.
- Adjusted the vertical size of the Mortgage Designer main window so that
CGA and EGA resolutions would show a taller opening screen. Before this,
CGA and EGA would show a fairly narrow main window.
- Changed all the list boxes from fixed line height to adjusted spacing
to prevent the list boxes from changing heights under some unusual video
modes and overwritting the top of the command buttons.
