What is a Mortgage?
A mortgage is a loan specifically designed for purchasing real estate. The property itself serves as collateral for the loan, meaning the lender can seize the property if the borrower fails to make the required payments. Mortgages typically consist of the principal, interest rate, loan term, monthly payments, and may include additional costs like property taxes and insurance.
Principal
The principal is the total amount of money borrowed to purchase the home. For example, if you buy a house for $300,000 and put down $60,000 as a down payment, the principal amount of your mortgage would be $240,000.

Interest Rate
The interest rate is the cost of borrowing money from the lender, expressed as a percentage of the principal. Interest rates can be fixed or variable:
- Fixed-Rate Mortgage: The interest rate remains the same throughout the loan term.
- Variable-Rate Mortgage: The interest rate can change periodically based on market conditions.
Loan Term
The loan term is the length of time you have to repay the mortgage. Common loan terms are 15, 20, or 30 years. The term you choose will affect your monthly payments and the total amount of interest paid over the life of the loan.
Monthly Payments
Monthly mortgage payments consist of both principal and interest. Over time, the portion of the payment that goes towards the principal increases, while the portion that goes towards interest decreases. This process is known as amortization.
The Mortgage Process
1. Pre-Approval
Before you start house hunting, it’s advisable to get pre-approved for a mortgage. Pre-approval involves a lender evaluating your financial situation to determine how much they are willing to lend you. This step helps you understand your budget and shows sellers that you are a serious buyer.
2. Finding a Property
Once pre-approved, you can begin searching for a home within your budget. When you find a property you like, you’ll make an offer. If the offer is accepted, you’ll move forward with the mortgage application process.
3. Mortgage Application
The mortgage application involves submitting detailed financial information to the lender. This includes income, assets, debts, and credit history. The lender will review this information to determine if you qualify for the loan.

4. Loan Processing and Underwriting
During this stage, the lender will verify your financial information and assess the risk of lending to you. They may request additional documentation and perform an appraisal to ensure the property’s value supports the loan amount.
5. Closing
If your loan is approved, you’ll move to the closing stage. This involves signing the final loan documents and paying any closing costs. Once completed, the lender will disburse the loan funds, and you’ll officially become a homeowner.

How Mortgage Repayments Work
Monthly Payments
Your monthly mortgage payment is typically made up of four components, often referred to as PITI:
- Principal: The portion of the payment that reduces the outstanding loan balance.
- Interest: The cost of borrowing, paid to the lender.
- Taxes: Property taxes, which are often escrowed and paid by the lender on your behalf.
- Insurance: Homeowners insurance, which protects against damage to the property.
Conclusion
A mortgage is a loan used to purchase real estate, with the property itself serving as collateral. Borrowers repay the loan through monthly payments that include principal, interest, and often taxes and insurance. Fixed-rate mortgages offer stable payments, while variable-rate mortgages fluctuate based on market conditions. Understanding the mortgage process—from pre-approval to closing—helps buyers make informed decisions and secure the best financing for their needs.
