Buying a house is exciting but can feel confusing. Most people use a mortgage to help pay for it. But what exactly is a mortgage? And how does it work? Let’s break it down in simple steps.
Note: In Islam, charging or paying interest (known as riba) is forbidden. This post is for informational purposes only, helping you understand how mortgages work. Knowledge is important to make informed choices.
What Is a Mortgage?
A mortgage is a loan you get from a bank or lender. You borrow money to buy a house. Then, you pay back the loan little by little every month.
Principal and Interest: The Two Big Parts
Your monthly mortgage payment has two main parts:
- Principal: This is the money you borrowed. When you pay principal, you reduce your loan balance.
- Interest: This is the cost of borrowing money. The bank charges you interest as a fee for lending.
How Does Interest Work?
Interest is a percentage of your loan. It is added to your monthly payment. Early on, most of your payment goes toward interest, not the principal.
For example, if you borrow $100 and pay 5% interest each year for 5 years, how much interest do you pay?
If the interest is simple (not compounded), you pay $5 each year:
$5 × 5 years = $25 in total interest.
So, you pay back $100 (the original loan) + $25 (interest) = $125 total.
However, if the interest compounds (interest added to the loan each year), the total interest will be more because you pay interest on the interest. This is only on $100. interest on $300,000 is a lot more.
How Long Does a Mortgage Last?
Mortgages usually last 15 to 30 years. This is called the loan term. You agree to pay the loan back over this time. Longer terms mean smaller monthly payments but more interest overall. Shorter terms mean higher payments but less total interest.
What Happens If You Can’t Pay?
If at any point you can’t continue paying, the bank may take back the house. This is called foreclosure. Since the house was bought with a loan, the bank has the right to take it and sell it to get their money back.
In most cases, you don’t get the money back that you already paid. That includes interest and part of the loan payments. If the house sells for less than what you owe, you may even still owe the bank more. If the house sells for more, you might get something back but that’s rare. Legal fees, selling costs, and penalties usually take the extra amount.
This is why it’s so important to make sure the mortgage fits your budget before signing anything.
Extra Costs to Know
Besides principal and interest, you may pay for:
Property taxes – A yearly tax you pay to your local government. This money helps pay for schools, roads, rubbish collection, and emergency services…
Home insurance – Insurance that protects your house in case of damage or disasters, usually required to get a mortgage
Sometimes, private mortgage insurance (PMI) – Extra insurance you might have to pay if your deposit is small, usually less than 20% of the home’s price. This protects the lender, not you. If you can’t repay the mortgage, PMI helps cover their loss. It adds to your monthly cost until you build more equity in the home.
These add to your monthly costs.
A real life example
Let’s say you buy a house for $300,000 with a 10% down payment ($30,000), and borrow $270,000 over 30 years at a 6.5% interest rate.
Monthly Mortgage Payment
- Loan Amount: $270,000
- Interest Rate: 6.5%
- Term: 30 years
Estimated Monthly Payment (Principal + Interest): $1,706
Now let’s add the extras:
Property Taxes
- Average property tax: 1.25% per year of the home value
- $300,000 × 1.25% = $3,750 per year
- Monthly: $312.50
Home Insurance
- Average yearly cost: $1,200
- Monthly: $100
Private Mortgage Insurance (PMI)
- Required because down payment is under 20%
- Typical PMI: 0.5%–1% per year of the loan
- $270,000 × 0.8% = $2,160 per year
- Monthly: $180
Total Estimated Monthly Cost:
- Mortgage (Principal + Interest) – $1,706
- Property Taxes – $312.50
- Home Insurance – $100
- PMI – $180
- Total per month – $2,298.50
Total Payment Over 30 Years
Total Number of Payments: 360 (12 per year × 30 years)
Total Mortgage Payment: $1,706 × 360 = $614,160
Interest Paid:
- Total paid: $614,160
- Original loan: $270,000
- Interest paid over 30 years = $344,160
Why Understanding Mortgages Matters
Knowing how mortgages work helps you plan better. You can budget for payments and avoid surprises. It also helps you decide if buying a home is the right choice.
Understanding how mortgages work shows just how expensive they really are. Over 30 years, you could end up paying more than double the original price of the home, most of it in interest. And remember, if you lose your job, get sick, or simply can’t keep up with payments, the bank can take the house, and you most likely lose everything you’ve already paid.
From an Islamic point of view, this system is clearly unjust and exploitative. That’s why Islam forbids riba (interest). It protects people from financial traps that benefit lenders while putting borrowers at serious risk. When you look at how much interest is paid, and how easily it can all be lost, it’s clear why Islam calls for a fairer, more ethical approach to owning a home.
