Practical Example: Buying a $350,000 New Build

Let’s walk through an example to see how the calculator works in real life.

• Property Price: $350,000
• Deposit Amount: $50,000
• Mortgage Term: 25 years
• Interest Rate: 4%
• Incentives: First-Time Buyer Grant ($5,000)
• Annual Taxes & Fees: $3,600

Step 1: Incentives Applied

• Property price = $350,000
• Less $5,000 grant = $345,000 adjusted price

Step 2: Loan Amount

• Adjusted price = $345,000
• Deposit = $50,000
• Loan amount = $295,000

Step 3: Monthly Mortgage Payments

• Loan: $295,000
• Interest rate: 4%
• Term: 25 years (300 months)
• Monthly mortgage (without taxes) ≈ $1,556
• Monthly taxes = $300 ($3,600 ÷ 12)
• Final monthly payment = $1,856

Step 4: Long-Term Costs

• Total repayment = ≈ $466,800
• Total interest paid = ≈ $171,800

Result:
With the grant applied, the buyer reduces their loan amount and saves on long-term interest.
