One of the most common debates I see in divorce goes something like this:
“I have a 2.75% mortgage. I cannot give that up.”
And I get it.
Those ultra-low COVID interest rates feel like gold.
But here’s the problem:
Focusing only on the interest rate often causes people to miss the real cost of keeping that loan—especially when equity has to be paid out to the other spouse.
Because the rate is only one piece of the puzzle.
How Equity Buyouts Usually Happen When You Keep the Low Rate
If one spouse wants to keep the home and also keep the existing low interest rate mortgage, the equity owed to the other spouse must be handled some other way.
That often means:
- Taking out a HELOC
- Using retirement funds
- Paying cash from savings
- Negotiating offsets with other assets
On paper, this can look smart:
“Why refinance into a higher rate when I can just add a HELOC?”
But this is where the analysis needs to go much deeper.
The HELOC Trap Most People Don’t See Coming
Under current IRS rules, HELOC interest is generally not tax-deductible unless the funds are used to substantially improve the home.
Paying out equity in a divorce does not qualify.
At the same time:
- Your first mortgage interest rate is so low
- The interest paid is often not enough to exceed the standard deduction
Which means:
You may not be deducting any mortgage interest at all.
So now you’re carrying:
- A low first mortgage with no meaningful tax benefit
- A higher-rate HELOC with no tax deduction
That “cheap” mortgage may not be so cheap after all.
Why Refinancing Can Sometimes Improve Real Cash Flow
This is where people are often surprised.
Yes, refinancing means accepting a higher interest rate.
But it can also:
- Eliminate the HELOC entirely
- Roll the equity payout into one loan
- Increase the amount of deductible mortgage interest
- Push you back into itemizing deductions
Once that door opens, additional deductions may become available depending on your situation—especially if:
- You work from home
- You are self-employed
- You itemize business or professional expenses
- Your post-divorce tax filing status changes
This is why the payment alone is never the right comparison.
Why This Requires a Team, Not a Guess
This is rarely a decision that should be made in isolation.
In many cases, we need to bring in:
- A Certified Divorce Financial Analyst (CDFA)
- A financial planner
- A CPA
Why?
Because the real question isn’t:
“Which option has the lower interest rate?”
It’s:
- What is my after-tax cost?
- What does my monthly cash flow actually look like?
- What assets am I sacrificing to preserve this rate?
- How does this decision affect my long-term financial stability?
Sometimes the low-rate mortgage is the right move.
Other times, it’s quietly costing far more than people realize.
The Biggest Mistake I See
The most common mistake is making this decision based on:
- Emotion
- Fear of higher rates
- Online mortgage calculators
- Incomplete legal advice
Divorce forces financial restructuring. Trying to freeze one piece of the picture—like an interest rate—can distort everything else.
The Bottom Line
Holding onto a low COVID mortgage after divorce isn’t automatically wrong.
But it’s also not automatically smart.
Until you evaluate:
- Equity payout structure
- Tax treatment
- Deductibility
- Opportunity cost of assets used
- Long-term affordability
You don’t actually know the cost.
That’s why these decisions should be modeled—not guessed.
If you’re weighing whether to keep a low interest rate mortgage, use a HELOC, or refinance as part of a divorce settlement, this is exactly the kind of analysis I help coordinate.
