Interested in a 40-Year Fixed Mortgage?
Every now and then, I take a look at a specific mortgage product to determine if it could be a good fit for a prospective (or existing) homeowner.
Today, we’ll digest a relatively popular home loan option, the “40-year mortgage.”
You may already be thinking, “40 years? I thought mortgages had terms of 30 years?” Is this a mistake?
Well, you’d be mostly right. The majority of mortgages issued today do have terms of 30 years. It’s certainly the most common loan term out there.
In fact, aside from 30-year fixed mortgages, which clearly last for 30 years, as the name implies, adjustable-rate mortgages also have terms of 30 years, despite lacking any reference to 30 years in their title.
Why a 40-Year Mortgage Term?
Okay, so we know the 40-year mortgage bucks the trend here, and adds 10 years on to the standard mortgage term. But why? What’s the point of paying a mortgage for an extra decade? That sounds like a lifetime commitment.
Well, the longer a mortgage amortizes (is paid off), the lower the monthly mortgage payment. Essentially, payments are stretched out over a longer period of time. Instead of 360 months, you’re looking at 480 months.
Let’s look at an example of a 40-year fixed mortgage:
Loan amount: $300,000
30-year fixed: $1410.71 @3.875%
40-year fixed: $1300.86 @4.25%
As you can see, the monthly mortgage payment on the 40-year mortgage is roughly $110 less each month.
40-Year Mortgage Rates Are Slightly Higher
You may have also noticed that the mortgage rate on the 40-year mortgage in my example is 0.375% higher than the interest rate on the 30-year fixed.
After all, a bank or lender is willing to give you a fixed rate for four decades, so they’re going to want a slight premium in exchange for all that uncertainty.
In other words, expect 40-year mortgage rates to be slightly more expensive. It might only be .125% higher than the 30-year, but could definitely range from bank to bank. The bigger problem is finding a lender that offers the product to begin with.
That being said, the short-term savings can increase how much house a buyer can afford, and also make qualifying easier (or even feasible) if a borrower’s debt-to-income ratio is too high for a 30-year mortgage. That’s assuming the lender qualifies the borrower at the 40-year amortization…
This is essentially why a borrower would go with the 40-year fixed – to buy more house or make their mortgage more “affordable.”
More aggressive borrowers could even invest that $110 each month in a high-yielding retirement account and essentially try to beat the relatively low interest rate on their mortgage.
Nowadays, a 40-year mortgage term may even be part of a loan modification program to make payments more affordable for a struggling borrower. When combined with an interest rate cut, the combo can help a borrower stay put in their home for the long haul.
The Downsides of a 40-Year Mortgage
While this all sounds good, a borrower who chooses to go with a 40-year mortgage is paying a premium to do so.
As mentioned, the mortgage rate is higher, so that cuts into the “discount” afforded by a 40-year mortgage.
And while the monthly mortgage payment might be lower, the total interest paid over the full term will be much higher, which makes one question whether $100 or so in monthly savings is worth it.
On smaller mortgages, the payment different will be even more negligible. It may also be difficult to find a 40-year mortgage, since not all lenders offer them.
In fact, the Qualified Mortgage rule outlawed loan terms longer than 30 years, so 40-year mortgages aren’t even QM-compliant. That means you’ll probably need to go with a specialty mortgage lender or portfolio lender if you want one.
Additionally, a longer amortization period means you build home equity a lot slower, which could prove to be an issue if you need to sell or refinance in the future and your loan-to-value ratio is still sky-high.
Some Benefits to a 40-Year Mortgage
Still, one could argue that most homeowners don’t stick with their mortgage full term anyway, let alone for 10 years, so why pay more each month? Or worry that it’ll take forever to pay it off?
It’s also safer than an ARM (assuming it’s a 40-year fixed), which can adjust higher once the fixed period comes to an end. So you won’t have to contend with any rate adjustments, which could make it easier to sleep at night.
Tip: You may come across a “40 due in 30” as well, which is essentially a 30-year balloon mortgage that amortizes like it has a 40-year term. That keeps monthly payments low, but there is a balance due at 30-year mark. Again, most of these probably aren’t kept full term, so it might be moot.
