Shirley Trembley Bought A House For $184,800. She Put 20% Down And Obtained A Simple Interest Amortized

When it comes to purchasing a home, understanding the financial details behind the transaction can be just as important as the house itself. For Shirley Trembley, buying a house for $184,800 involved strategic planning around her down payment, loan terms, and interest calculations. This article explores her mortgage scenario in detail, providing insights into how she financed her home using a 20% down payment and a simple interest amortized loan. Whether you're a prospective homebuyer or simply interested in real estate financing, this comprehensive guide will shed light on the key concepts involved.

Understanding the Purchase Price and Down Payment

The Purchase Price

Shirley’s chosen home was priced at $184,800. This figure represents the total amount agreed upon between the buyer and seller for the property. The purchase price is the starting point for calculating other financial aspects such as the down payment and loan amount.

The Down Payment: 20%

A common rule of thumb in real estate is to make a 20% down payment, which Shirley did. This percentage has several benefits:
    • Lower Loan Amount: A higher down payment reduces the principal amount borrowed, decreasing overall interest costs.
    • Lower Monthly Payments: Smaller loan balances translate into more manageable monthly payments.
    • Better Loan Terms: Lenders often view sizable down payments favorably, potentially qualifying for better interest rates.

Calculating Shirley’s Down Payment:


  • 20% of $184,800 = 0.20 × $184,800 = $36,960


This means Shirley paid $36,960 upfront, reducing her financed amount to:

Loan Principal = Purchase Price – Down Payment


  • $184,800 – $36,960 = $147,840


Loan Details and Interest Calculation

Type of Loan: Simple Interest Amortized

Shirley obtained a simple interest loan that is amortized over the loan term. Unlike compound interest, simple interest is calculated solely on the remaining principal balance, making the interest cost more predictable and straightforward.

Key features of her loan:


  • Simple interest basis: Interest is calculated daily based on the outstanding balance.

  • Amortized payments: Equal monthly payments that cover interest and principal over the loan term.

  • Fixed interest rate: Assumed for this scenario, providing consistent monthly payments.


Calculating the Interest


The simple interest formula:
\[
\text{Interest} = \text{Principal} \times \text{Interest Rate} \times \text{Time}
\]

However, in mortgage calculations, the interest is typically calculated daily and paid monthly, based on the outstanding balance.

Suppose Shirley’s loan has:


  • An annual interest rate of 5% (a common rate, though actual rates vary)

  • A loan term of 30 years (360 months)


Daily interest rate:
\[
\frac{5\%}{365} \approx 0.0137\%
\]

Each month, interest is calculated on the remaining principal.

Calculating Monthly Payments

The Amortization Process

Amortized loans are designed so that the borrower makes equal payments throughout the loan term. Each payment covers:
  • The interest accrued for that period
  • A portion of the principal balance
Standard amortization formula: \[ M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1} \] Where:
  • \( M \) = monthly payment
  • \( P \) = principal loan amount ($147,840)
  • \( r \) = monthly interest rate (annual rate / 12)
  • \( n \) = total number of payments (months)
Assuming:
  • Annual interest rate = 5%
  • \( r = \frac{5\%}{12} = 0.004167 \)
  • \( n = 30 \times 12 = 360 \)
Calculating Shirley's monthly payment: \[ M = 147,840 \times \frac{0.004167(1 + 0.004167)^{360}}{(1 + 0.004167)^{360} - 1} \] Using a mortgage calculator or financial software:
  • Monthly payment ≈ $793.34
This payment remains consistent throughout the loan term, with the interest component decreasing and the principal component increasing over time.

Breaking Down the Payments: Interest vs. Principal

During the early years, Shirley’s payments mainly cover interest, with a smaller portion reducing the principal. Over time, as the loan progresses, more of each payment goes toward reducing the principal.

Example of the first payment:


  • Interest for Month 1:

\[
\text{Interest} = \text{Principal} \times \frac{\text{Annual Rate}}{12} = 147,840 \times 0.004167 \approx \$615.60
\]

  • Principal repayment:

\[
793.34 - 615.60 \approx \$177.74
\]

  • Remaining balance after Month 1:

\[
147,840 - 177.74 \approx \$147,662.26
\]

Over the course of the loan, the interest component decreases, and Shirley’s equity in the home increases.

Advantages of Simple Interest Amortized Loans

Choosing a simple interest amortized loan offers several benefits:



    • Transparency: Easy to understand how interest accrues and how payments are applied.


    • Potentially lower interest costs: Since interest is calculated on the outstanding principal, early payments reduce the total interest paid over the life of the loan.


    • Consistent payments: Fixed monthly payments simplify budgeting and financial planning.

Impact of Down Payment and Loan Terms on Total Cost

Shirley’s 20% down payment significantly reduced her total loan amount, lowering her interest costs over time. Additionally, her choice of a simple interest amortized loan with a fixed rate ensures predictable payments and total interest paid.

Total interest paid over the life of the loan:


  • Approximate calculation:

\[
\text{Total paid} = 793.34 \times 360 = \$285,601.44
\]
\[
\text{Total interest} = \$285,601.44 - \$147,840 = \$137,761.44
\]

This represents the total interest Shirley will pay throughout her 30-year mortgage.
