Lesson Narrative
Students dive into the mechanics of home buying. They will compare Fixed-Rate Mortgages to Adjustable-Rate Mortgages (ARMs) and calculate the financial dangers of fluctuating interest rates. They will also deconstruct a monthly mortgage payment into PITI (Principal, Interest, Taxes, and Insurance) managed via an Escrow account.
Learning Goals
• Differentiate between fixed and adjustable-rate mortgages (ARMs).
• Deconstruct a mortgage payment into PITI components.
• Explain the function of an escrow account.
Student Facing Learning Goals
• Let's learn how home loans work and what actually goes into a monthly mortgage payment.
Student Facing Learning Targets
• I can explain the difference between a Fixed Mortgage and an ARM.
• I know what PITI stands for.
• I can explain how an Escrow account works.
Required Academic Standards
National Jump$tart Standards:
• Credit and Debt (Standard 1): Analyze the costs and benefits of various types of credit.
Glossary Entries
Fixed-Rate Mortgage: A home loan with an interest rate that stays the exact same for the entire term.
Adjustable-Rate Mortgage (ARM): A home loan where the interest rate changes periodically based on the economic market.
Escrow Account: A third-party account where funds are held to pay property taxes and insurance.
PITI: Principal, Interest, Taxes, and Insurance —the four core components of a mortgage payment.
Lesson
Warm Up
5.3.1: The Changing Bill
Launch: Have students stand in randomized groups of 3 at vertical whiteboards. Present the prompt verbally or project it. Give them 4 minutes.
Synthesis: Select two groups to share. Establish the baseline: While rent goes up every year, a mortgage payment usually stays the same. But if you sign the wrong type of loan contract, the bank can legally raise your price.
Student Facing Task
Student-Facing Task: Imagine you sign a contract to pay $1,500 a month for your house. Three years later, the bank says you now owe $2,100 a month for the exact same house. How could this legally happen?
Activity 1
5.3.2: Fixed vs. ARM Math
Launch: Keep students at whiteboards. Project the interest rate scenario. Give groups 8 minutes to run the analysis.
Synthesis: Have the class observe the boards. (Teacher Key: Homeowner A's payment stays exactly the same. Homeowner B's payment skyrockets). Explain that an ARM transfers the risk of economic inflation from the bank directly to the homeowner.
Student Facing Task
Student-Facing Task: Homeowner A has a Fixed 30-year mortgage at 5%. Homeowner B has a 5/1 ARM (Adjustable Rate) that starts at a "teaser" rate of 4%. After 5 years, the economy crashes and interest rates skyrocket to 9%.
1. What happens to Homeowner A's monthly payment?
2. What happens to Homeowner B's monthly payment?
3. Why is an ARM a massive financial risk for the buyer?
Activity 2
5.3.3: Deconstructing PITI
Launch: Present the escrow scenario. Give the whiteboard groups 10 minutes to analyze the payment breakdown.
Synthesis: Facilitate a class debate. (Key: Taxes and Insurance). Explain that the bank doesn't trust you to save for taxes. If you don't pay your property tax, the government seizes the house, which means the bank loses their collateral. Escrow protects the bank.
Student Facing Task
Student-Facing Task: Your mortgage is made up of PITI (Principal, Interest, Taxes, Insurance). You get a monthly bill for $2,000. $1,000 goes to the bank's interest, and $500 goes to pay down your loan principal. The remaining $500 goes into a mandatory "Escrow" account.
1. What two major yearly bills is the bank saving that $500 to pay for you?
2. Why doesn't the bank just trust you to pay those two bills yourself at the end of the year?
Lesson Synthesis
Lesson Synthesis (5 min)
Narrative: Bring the class back to their seats. Review the student-facing learning targets. Summarize: "A house is a great investment because it locks in your housing cost for 30 years—but only if you choose a fixed-rate mortgage. An ARM leaves you vulnerable to the market."
Cool Down
5.3.4: The Escrow Explanation
Narrative: This exit ticket serves as a formative assessment on escrow mechanics and collateral protection.
Teacher Rubric: A successful response must articulate that the bank uses escrow to force the homeowner to pay property taxes and insurance in monthly installments. This ensures the house isn't seized by the government or destroyed in a fire without insurance, protecting the bank's collateral.
Student Facing Task
Student-Facing Task: Why does a mortgage lender force you to pay for your property taxes and home insurance through an Escrow account every single month, instead of letting you handle those bills yourself?
