What is a Mortgage?
A mortgage is a loan used to purchase real estate, where the property itself acts as collateral. The borrower agrees to repay the loan over a fixed period, typically 15 to 30 years, through regular monthly payments.
Each payment includes a combination of:
- Principal (the amount borrowed)
- Interest (the cost of borrowing)
- Taxes (property-related)
- Insurance (home protection)
This full payment structure is commonly referred to as PITI:
- Principal
- Interest
- Taxes
- Insurance
How Mortgage Payments Work
Your monthly mortgage payment is more than just loan repayment. It often includes several components that impact your total cost of homeownership.
1. Principal
This is the portion of your payment that reduces your loan balance.
2. Interest
This is the cost charged by the lender for borrowing money. It is highest at the beginning of your loan and decreases over time.
3. Property Taxes
Local governments charge taxes based on the value of your property. These are often included in your monthly payment.
4. Home Insurance
Protects your property against damage or loss. Lenders usually require insurance coverage.
5. Mortgage Insurance (PMI / LMI)
If your down payment is less than 20%, you may be required to pay mortgage insurance.

warning Low Down Payment Considerations:

What is an Amortization Schedule?
An amortization schedule is a detailed table that shows how your mortgage is repaid over time. It includes:
- Monthly payment details
- Interest paid per period
- Principal repayment
- Remaining balance
In the early years, most of your payment goes toward interest. Over time, the principal portion increases, helping you build equity in your home.
What is Equity and Why It Matters
Equity is the portion of your home that you truly own. It increases as you:
- Pay down your mortgage
- Benefit from property value appreciation
Higher equity gives you:
- Better refinancing options
- Access to home equity loans
- Greater financial security

- Interest rates have dropped
- Your credit score has improved
- You want to reduce monthly payments
- You want to shorten your loan term
However, always consider closing costs and the break-even point before refinancing.
