Homes or commercial buildings
Any other type of structure

Mortgage: a loan in which real property is used to secure the debt.
Collateral: the property that is held as security on a mortgage.
Equity: the difference between the expected selling price and the balance owed on the property.

Conventional mortgages
Two types include:Fixed-rate mortgage: the rate of interest on
the loan remains the same for the life of the mortgage.
Adjustable-rate mortgage: the rate of interest may fluctuate during the life of the loan depending on the prime lending rate of most banks.

Mortgage payments 15 - year and 30 - year loans are the most
common. Payments can be made monthly or on a
biweekly plan, resulting in 26 payments. The biweekly plan builds equity more quickly
than the monthly plan. An equity line of credit, or second mortgage,
allows a homeowner to borrow against the equity in the home. It is in addition to the first mortgage.

15.1.1 Find the monthly mortgage payment using a table
The repayment of a loan in equal installments that are applied to principal and interest over a period of time is called the amortization of a loan.
To calculate the monthly mortgage payment, it is customary to use a table. (See Figure 15.1 in your text.)

Use a per-$1,000 monthly payment table
Monthly mortgage payment
is equal to
Amount financed x table value
$1,000

Look at this example
A homebuyer is purchasing a house for $87,000. The bank has approved her loan application for a 30-year fixed-rate loan at 7% annual interest. If she makes a 20% down payment, what is the monthly payment?
Calculate the down payment: $87,000 x 0.20. It is $17,400. The balance to be financed would be $69,600. Divide $69,600 by $1,000 = 69.6.
11Cleaves/Hobbs: Business Math, 7e Copyright 2005 by Pearson Education, Inc. Upper Saddle River, NJ 07458 All Rights Reserved
Example (continued)
Using Table 15-1, find the factor for financing a loan for 30 years at 7%.
The factor is 6.65
Multiply this factor (6.65) by number of thousands (69.6).
The result is $462.84
The monthly payment of $462.84 includes the principal and the interest.

Try this example.
Joan Williams has been approved for a 30-year fixed-rate loan at 6.5%. The home that she is purchasing costs $140,000; she is going to put 20% down.
Calculate her monthly payment including principal and interest using Table 15-1.
$707.84

15.1.2 Find the total interest on a mortgage
Find the total number of payments: multiply the number of payments by the amount of the payment.
Subtract the amount financed from the total of the payments.
14Cleaves/Hobbs: Business Math, 7e Copyright 2005 by Pearson Education, Inc. Upper Saddle River, NJ 07458 All Rights Reserved
Look at this example In the example on Slide 11, the monthly
payment of the principal and interest is $462.84. The buyer has a 30-year fixed mortgage.
Total interest = number of payments x amount of payment – amount financed.
TI = 30 x 12 x $462.84 - $69,600
TI = $166,622.40 - $69,600
The total interest on this loan is $97,022.40

Key Terms Other costs involved in securing a mortgage
include: points, attorney fees, and sales commissions among others. These are called closing costs, and are paid when the loan is made.
Points: a one-time payment to the lender that is a percent of the total loan.
Escrow: an account for holding the part of a monthly payment that is used to pay taxes and insurance.

PITI
The adjusted monthly payment that includes the principal, interest, taxes and insurance is abbreviated “PITI.”
The monthly mortgage payment that the borrower will make will include all four elements.
18Cleaves/Hobbs: Business Math, 7e Copyright 2005 by Pearson Education, Inc. Upper Saddle River, NJ 07458 All Rights Reserved
Look at this example. Our home buyer (from Slides 11 and 14) has a
monthly payment of principal and interest of $462.84. If her annual insurance premium is $923 and the property taxes are $950, find the adjusted monthly payment that includes PITI.
$923 + $950 = $1,873 ÷ 12 = $156.08
Add the above amount to the monthly principal and interest payment of $462.84.
The adjusted monthly payment = $618.92

The other homebuyer has a monthly payment of principal and interest of $707.84. If her annual insurance premium is $1,200 and her property taxes are $1,500, what would the adjusted monthly payment be?

15.2 Amortization schedules
To prepare an amortization schedule of a mortgage:
Step 1: For the first month,
• Find the interest portion of the first monthly payment = original principal x monthly interest rate.
• Find the principal portion of the monthly payment = monthly payment – interest portion of the first monthly payment.
• Find the end of month principal = original principal –principal portion of the first monthly payment.
21Cleaves/Hobbs: Business Math, 7e Copyright 2005 by Pearson Education, Inc. Upper Saddle River, NJ 07458 All Rights Reserved
For each remaining month in turn: Step 2 (for each remaining month)
Find the interest portion of the monthly payment = previous end-of-month principal x monthly interest rate.
Find the principal portion of the monthly payment = monthly payment – interest portion of the monthly payment.
Find the end-of-month principal = previous end-of month principal – principal portion of the monthly payment.
22Cleaves/Hobbs: Business Math, 7e Copyright 2005 by Pearson Education, Inc. Upper Saddle River, NJ 07458 All Rights Reserved
Look at this example From the first home buyer example,
Interest = original principal x monthly rate
Interest = $69,600 x 0.07 /12
Interest = $406.00
Principal portion of the monthly payment =$462.84 - $406 = $56.84
End-of-month principal =$69,600 - $56.84 = $69,543.16
23Cleaves/Hobbs: Business Math, 7e Copyright 2005 by Pearson Education, Inc. Upper Saddle River, NJ 07458 All Rights Reserved
Example (continued)Second month
Interest portion = $69,543.16 x 0.07 / 12
Interest portion = $405.67
Principal portion of monthly payment =$462.84 - $405.67 = $57.17
End of month principal = $69,543.16 - $57.17 = $69,485.99
Follow the same steps for subsequent months.

Try this example
Joan Williams, the other homebuyer, has a monthly mortgage payment of $707.84; an original loan amount of $112,000 and a 6.5% interest rate. Calculate the first two months of an amortization schedule.
First end-of-month principal =$111,898.82
Second end-of-month principal =$111,797.09
