What Is a Mortgage Loan?

Understanding the Basics
A mortgage loan is a type of loan used to purchase a home or property. It is a secured loan where the lender provides funds to the borrower, and in return, the borrower agrees to repay the loan amount with interest over a fixed period. The home itself serves as collateral, meaning the lender can seize the property if the borrower fails to repay the loan.
Key Components of a Mortgage Loan
- Principal – The original amount borrowed.
- Interest – The cost of borrowing money, usually expressed as a percentage (interest rate).
- Loan Term – The length of time given to repay the loan (e.g., 15, 20, or 30 years).
- Monthly Payments – Consist of principal, interest, property taxes, and insurance.
- Down Payment – The upfront amount paid by the borrower, usually between 3%–20% of the home price.
How Does a Mortgage Loan Work?
Step-by-Step Mortgage Loan Process
- Pre-Approval – Before house hunting, you apply for mortgage pre-approval, where the lender assesses your creditworthiness and income.
- House Hunting & Offer – You find a home within your budget and make an offer.
- Loan Application – Once the offer is accepted, you formally apply for the mortgage.
- Underwriting Process – The lender reviews your financial situation and the property’s value.
- Loan Approval & Closing – If approved, you sign the loan agreement, pay closing costs, and get the keys to your new home.
- Repayment Begins – You start making monthly mortgage payments until the loan is fully paid off.
Factors That Affect Mortgage Approval
- Credit Score – Higher scores qualify for better interest rates.
- Income & Employment History – Stable income improves approval chances.
- Debt-to-Income Ratio (DTI) – Lenders prefer a DTI below 43%.
- Down Payment Amount – A larger down payment reduces loan risk.
