For many Americans, buying a home is the biggest purchase they will ever make. As borrowing costs rise, monthly mortgage payments become more difficult to handle. Freddie Mac reported that the average rate on a 30-year fixed mortgage stood at 7.24%.
Against that backdrop, interest-only mortgages can start to look appealing. They may provide short-term breathing room, but for most borrowers, the downsides can outweigh the advantage.
How an Interest-Only Mortgage Can Lower Costs
The main draw of this type of loan is affordability. Freddie Mac says borrowers pay only interest during the first years of the mortgage, usually for five to seven years. That can be attractive for people who want to buy a home but cannot comfortably manage a conventional loan.
The result is a smaller monthly payment, which leaves more room in the budget. Still, the loan does not reduce the home’s price or the total debt burden; it simply postpones principal repayment.
When the interest-only period ends, borrowers must start paying down principal, refinance, take out another interest-only loan or sell the home, according to Chase.
The Main Danger Is What Comes Later
When rates are rising, it is easy to understand why someone might consider this option. But the lower upfront payment comes with meaningful risk.
Once principal payments begin, the monthly bill can jump sharply. If your finances have not improved by then, you may face a difficult choice. Refinancing may be available, but there is no assurance that rates will be lower or that you will qualify.
There is also the risk that the home’s value could fall while you are in the interest-only phase. Because no principal is being paid down, negative equity is possible, according to The Wall Street Journal. If you simply need more time before taking on a traditional mortgage, waiting may be the safer path.
When an Interest-Only Mortgage Can Make Sense
An interest-only mortgage is not automatically a bad choice. Under the right circumstances, it can work for some buyers. Even with the lower initial payment, certain borrowers may have reasons to prefer it.
Chase notes that people buying a second home and real estate investors may find this structure useful, especially if they do not plan to remain in the property for long. The bank also says borrowers who expect to pay off the loan faster than a standard mortgage might benefit from the flexibility.
With careful planning, high earners or borrowers with significant assets may also be in a position to manage the risk.
What to Consider Before Choosing One
An interest-only loan can make monthly housing costs look more manageable. That may be especially appealing when rates are elevated. Rocket Mortgage says that even a 1% rate increase can add about $60 to $70 per month for every $100,000 borrowed on a typical mortgage.
Still, it is not enough to focus only on the lower introductory payment. A better test is whether you could realistically afford the home once the interest-only period ends.
It is wise to compare quotes for both a standard mortgage and an interest-only loan. Rather than zeroing in on the initial payment alone, look at the full long-term picture. If a conventional mortgage is out of reach and the added risk is not appealing, other options remain, including buying a less expensive home, choosing a different loan type or waiting.
Interest-only mortgages may seem more tempting while rates remain above 7%. They can temporarily ease monthly payments, but those costs may rise significantly in a few years. Unless you have a clear strategy and strong financial support, the trade-off may not be worth it.
