Here's Why Some Redditors Say You Should Keep Your Sub-4% Mortgage — Even If Your Budget's Tight
A recent Reddit post asking whether a homeowner should sell a house during a divorce sparked a much broader conversation than perhaps anyone expected. Instead of focusing on the relationship aspect, several commenters honed in on one specific detail: the homeowner’s 3.75% mortgage and whether keeping the house in the divorce was worth it.
Their message was surprisingly consistent. In today’s higher-rate environment, many people see a sub-4% mortgage as more than just a loan — it’s a financial asset worth protecting. Here's why these Redditors said the original poster should keep their sub-4% mortgage.

You (Probably) Can’t Replace That Interest Rate
The most common argument throughout the thread was a simple one: If you give up a mortgage below 4%, you may never get another one
“The 3.75% rate is cheap rent … and your kids need some stability,” wrote Reddit user SkyTorv in one of the discussion’s most-upvoted responses.
Another commenter, Giraloco, broke down why so many feel that way. Using a $500,000 mortgage as an example, they estimated that replacing a 3.75% loan rate with something more in keeping with 2026 rates would increase monthly mortgage payments by roughly $2,000.
There May Be Better Options Than Selling
Rather than immediately selling the home, a number of commenters suggested looking for ways to preserve the existing mortgage.
User BiggC proposed “a home equity loan or second mortgage” to buy out the other spouse’s equity instead of refinancing the primary mortgage. Preserving a low monthly payment can create room in a person’s budget for extra savings for retirement, emergency funds or debt repayment.
The Experts Agree
“Having a sub-4% mortgage is a huge privilege in today’s market because the house you have is a lot less expensive than the same house if you were to rebuy at 6% to 7% rates,” said Taylor Tassone, mortgage broker and founder of Tayton Capital.
“Homeownership is not an inexpensive thing — being a homeowner comes with lots of costs, insurance, taxes, upkeep, etcetera. If it becomes too expensive and you have a mortgage with sub-4%, maybe moving out and turning it into a rental is a good move. With rates that low, odds are pretty good that you would actually be able to generate cash flow on that property and keep it long term. The homeowner can then move out and into a rental of their own and use the cash flow to help subsidize their monthly costs.”
The Bottom Line
The Reddit discussion makes clear that homeowners should consider sub-4% mortgages as valuable financial assets and not just a monthly bill. If you have such a rate and can afford the payments, keeping a below-market mortgage may be worth far more than you realize.
