Buying a home can be a great long-term move. It offers stability, a place of your own, and the potential for appreciation over time. But the financial mechanics of a mortgage can surprise first-time buyers, especially in the early years.
This isn’t about discouraging homeownership. It’s about understanding how the math works so you can make smart decisions that fit your bigger financial plan.
Where Mortgage Rates Sit Today
The current average 30-year fixed mortgage rate is in the mid-6% range. That means your monthly payment is higher than it would have been just a few years ago, and the early years of the loan are especially interest heavy.
The First 7 Years, by the Numbers
On a standard 30-year fixed mortgage at 6.56%, your payment each month is fixed—but how much of that payment goes toward interest versus principal changes over time.
Here’s how it breaks down roughly in the first 7 years:
Year 1: about 14.5% to principal
Year 2: about 15.6% to principal
Year 3: about 16.6% to principal
Year 4: about 17.9% to principal
Year 5: about 19.1% to principal
Year 6: about 20.3% to principal
Year 7: about 21.6% to principal
In other words, during your first few years as a homeowner, most of your money is servicing interest rather than building equity. That can feel discouraging if you don’t expect it, but it’s simply how mortgage amortization works. Over time, the share going to principal steadily increases.
The Ongoing Costs of Homeownership
Your true cost of owning a home is more than just the mortgage. Here are major ongoing expenses that need to be factored in:
Property taxes – Often 1% (or more) of your home’s value annually.
Homeowners insurance – Protects your property and satisfies lender requirements.
Maintenance and repairs – A common rule of thumb is 1–2% of your home’s value per year.
HOA fees – If your neighborhood has a homeowners association.
Utilities – Larger spaces usually mean higher heating, cooling, and water bills.
Private Mortgage Insurance (PMI) – If you put down less than 20%.
When added together, these costs can increase your monthly outlay by 20–30% above the mortgage payment alone.
Why Homeownership Still Makes Sense
Even with these costs, homeownership can still be a powerful wealth-building tool when done strategically:
Homes tend to appreciate over long time horizons.
Principal paydown creates a forced savings effect.
You can fix your housing cost in place with a 30-year mortgage.
You get the personal and lifestyle benefits of stability and control.
The key is to remember that your home is one piece of your overall financial strategy, not the entire strategy.
Smart Steps Before Buying
Run the full numbers – Don’t just look at the mortgage payment.
Stick to a safe budget – The 28/36 rule is a helpful guide (28% of gross income on housing, 36% on total debt).
Keep investing elsewhere – Don’t stop contributing to retirement or brokerage accounts.
Plan for the unexpected – Keep cash reserves for repairs and life surprises.
Think about your timeline – If you may sell within 5–7 years, weigh transaction costs against expected appreciation.
Final Takeaway
Owning a home can be a smart move, but the math tells a clear story. In the first seven years, only about 15–22% of your annual payments actually reduce your loan balance. The rest goes to interest. Add in property taxes, insurance, and maintenance, and the cost of owning is higher than many first-time buyers expect.
The good news? Over time, more of your payment builds equity, and if you plan wisely, your home can be both a place to live and a valuable part of your overall wealth-building journey.
