As mortgage rates fluctuate, many experts predict a surge in home buying if rates drop significantly. Even well-known financial expert Dave Ramsey believes a rate decline could trigger a sharp increase in buyer demand.

In a recent interview with TheStreet, Ramsey suggested that if mortgage rates decrease by just one or two percentage points, buyers waiting on the sidelines could re-enter the market in full force.

This kind of drop could create renewed momentum in the housing market, especially in areas like St. Louis, where affordability has been a challenge in recent years.

But Ramsey is also known for his conservative homebuying advice, which may still prevent some from qualifying—even if interest rates fall.

Dave Ramsey Sees Mortgage Rate Decline and Housing Market Recovery

While Dave Ramsey didn’t give exact reasons why he thinks mortgage rates will drop, he remains optimistic about the direction of the housing market. He believes that as rates decrease, the real estate market—especially in cities like St. Louis—could rebound strongly.

He’s also skeptical that home prices will fall much further. Despite an increase in housing inventory in 2025, demand still appears to outpace supply.

That means prices may hold steady, and buyers who’ve been waiting for a better opportunity could start competing again once mortgage rates improve.

This aligns with what we’ve seen at Carlson Mortgage, a top-rated St. Louis mortgage broker. Many local buyers have been sitting tight, hoping for better interest rates before making their move.

In fact, 2024 recorded the lowest level of existing home sales since 1995. While 2025 hasn’t drastically improved yet, much depends on the trajectory of interest rates, the broader economy, and global trade conditions.

Can You Afford a Home in St. Louis Using Ramsey’s Math?

Dave Ramsey has long been vocal about his strict financial rules for buying a home. His most notable guideline? Spend no more than 25% of your take-home pay on your monthly mortgage payment.

That’s significantly lower than the debt-to-income ratios allowed by lenders like Fannie Mae, Freddie Mac, and FHA, which often approve buyers with DTI ratios over 40%.

Even more limiting: Ramsey only recommends 15-year fixed-rate mortgages—and advises buyers to make at least a 20% down payment.

Let’s break it down using a practical example for a St. Louis homebuyer:

• Annual income: $100,000
• Take-home pay: ~$6,561/month
• Home price: $360,000 (approximate U.S. average)
• Down payment: 20% ($72,000)
• Loan amount: $288,000
• Interest rate: 6% on a 15-year fixed loan
• Monthly payment (P&I): $2,430
• Taxes & insurance: ~$475
• Total monthly cost: $2,905

That’s about 44% of take-home pay—well above Ramsey’s 25% limit, which would cap the total monthly payment at $1,640.

For Ramsey’s Rules to Work, Mortgage Rates Must Fall Dramatically

According to his guidelines, buyers could only allocate about $1,165 toward principal and interest, after taxes and insurance.

That budget isn’t compatible with today’s mortgage rates and home prices—especially if buyers are restricted to 15-year terms.

Even a 1% mortgage rate wouldn’t lower the monthly payment enough to meet his strict threshold.

Here at Carlson Mortgage, we understand that while Ramsey’s principles are financially conservative, they don’t reflect the realities of today’s St. Louis market. Most buyers we work with choose 30-year fixed loans with low down payment options, and we help them get some of the lowest interest rates in Missouri.

We also pride ourselves on never charging broker fees, processing fees, or points—something few banks or lenders can match.

Bottom Line: If Rates Drop, Demand in St. Louis Could Soar

If mortgage rates fall one or two percentage points, St. Louis could see a homebuying boom. But it’s worth considering what such a drop would signal about the economy—major rate reductions often follow a recession or market correction.

Still, for many local buyers, even a modest drop in rates could be the opportunity they’ve been waiting for.

At Carlson Mortgage, we’ve helped thousands of Missouri clients navigate complex markets over the last 20 years. As an independent St. Louis mortgage broker, we work with a wide range of lenders to get you the best possible loan—without hidden fees or bias toward any one bank.
