Episode Overview

This episode focuses on the risks and realities of putting less than 20% down when buying a home, challenging the common theory that investing extra cash can outperform a larger down payment. Dave Ramsey and Rachel Cruze debate the wisdom of financial “optimization,” advocating for peace of mind and consistency over mathematical risk-taking. The conversation also touches on the appeal—and dangers—of adjustable-rate mortgages (ARMs) for first-time home buyers and provides actionable advice for building long-term wealth.

Key Discussion Points & Insights

1. Should You Put Down Less Than 20% to Invest the Rest?

• Caller Brandon’s Dilemma (00:06):
  • Brandon and his fiancée can afford a 20% down payment but wonder if it’s better to put only 10% down and invest the difference, citing potential for higher returns via index funds or ETFs.
• Dave Ramsey’s Response (00:37):
  • Dave argues this approach ignores risk and true wealth-building behaviors.
  • Quote (00:37):
    “Your formula left out something called risk and it left out something towards good night's sleep when your home is steady... The number of them [millionaires] that said ‘we optimized our home mortgage by putting as little down as possible to invest and became a millionaire that way’—that was precisely zero. No one does that in the real world." — Dave Ramsey
  • Ramsey references a study of over 10,000 millionaires, noting the vast majority reached wealth by paying off their homes and building savings—not by maximizing leverage.
  • He discusses intangible benefits: peace of mind, better relationships, less career stress, and improved health through reduced financial anxiety.

2. The Adjustable-Rate Mortgage (ARM) Trap

• Brandon’s Situation (03:03):
  • Brandon and his fiancée are considering a five-year ARM, planning to stay in their starter home for only 4–5 years, assuming they can sell before the rate adjusts.
• Dave’s Caution (03:52):
  • Dave flatly rejects the ARM idea, warning about unpredictable life circumstances.
  • Quote (03:58):
    “You have a plan, but your plan is not going to unfold the way you think... So you put together things that are sustainable and don't add extreme risk to your situation.” — Dave Ramsey
  • He recounts stories of families forced out of homes by ARM adjustments after unexpected life events, emphasizing the need for fixed, predictable payments.

3. The Power of Simplicity & Consistency

• Rachel Cruze’s Encouragement (05:07):
  • Rachel highlights the importance of doing “really boring common sense stuff”—living below your means, avoiding debt, investing consistently, and focusing on earning.
  • Quote (05:17):
    “If you just do really boring common sense stuff with money... you guys make an insane income and you just do those things.” — Rachel Cruze
• Dave’s Confirmation (06:43):
  • Dave notes that real wealth comes from consistency, not picking the exact optimal investment or mortgage product.
  • Quote (08:37):
    “They over-indexed on consistency and they under-indexed on fund choice.” — Dave Ramsey

4. Real-Life Evidence Over Theoretical Models

• Why “Optimization” Fails for Most People (07:17):
  • Ramsey emphasizes that data—not financial theory—shows most millionaires win by steady, not “optimized,” behavior.
  • Example (08:54):
    • People constantly chase complex strategies or better returns, but usually fail due to inconsistency.
  • Consistency vs. Complexity (09:00):
    “They try this little thing and then they try this other little thing... they're always scheming and scamming, trying to cut a half [percentage point].” — Dave Ramsey

5. Peace and the Emotional Side of Financial Decisions

• Paying Off the House (09:05):
  • Rachel shares that among thousands of people at Ramsey events, “no one” has ever regretted paying off their home.
  • Quote (09:36):
    “None.” — Dave Ramsey
    “Never. ...when you solve for peace, as Dr. John Deloney says, with your money, that is worth it.” — Rachel Cruze

6. Closing Advice: It's About You, Not the Math

• Self-Reliance & Simplicity (06:28):
  • Rachel and Dave stress that true financial success comes from the people involved, not the system or strategy.
  • Quote (06:28):
    “I'm telling you, people that win with money, long term, it's them, they're the reason they win. It's not this system that you kind of rig here or there.” — Rachel Cruze

Notable Quotes & Memorable Moments

• Risk & Real Wealth:
  “No one does that in the real world. That's a mathematical theory that doesn't hold water.” — Dave Ramsey (00:37)
• Adjustable Rates as a Gamble:
  “So nothing works out exactly the way you think it's going to. And so you put together things that are sustainable and that don't add extreme risk.” — Dave Ramsey (03:58)
• The Value of Consistency:
  “They were somewhere around that 80 percentile. ...What they did do is... They never missed a month. Consistency, forever. No matter what.” — Dave Ramsey (07:17, 08:37)
• No Regrets, Just Peace:
  “None. Never. So again, that's not in a formula, but I'm telling you, like, when you solve for peace... that is worth it.” — Dave Ramsey & Rachel Cruze (09:36)
• It's About Character, Not Tricks:
  “People that win with money, long term, it's them, they're the reason they win. It's not this system you kind of rig here or there.” — Rachel Cruze (06:28)

Summary & Actionable Takeaways

[Brandon (Caller)]

My fiance and I just got engaged and we're looking to buy our first home. And I was trying to understand the so basically we have the ability to put 20% down on the home but based off of, you know, all the math behind in the numbers I've seen, it seems more optimal to possibly put down less and have more liquid cash available to invest. Call it maybe 10% down with having the extra cash you're able to invest long term and say VU or QQQ or like a large cap ETF or index fund but wanted to get your thoughts on it.

[Dave Ramsey]

It's not optimal. Your formula left out something called risk and it left out something towards good night's sleep when your home is steady. We studied 10,167 millionaires. 89% of them were first generation rich, meaning they started where you are and became wealthy. The number of them that said we were we optimized our home mortgage by putting as little down as possible to invest and became a millionaire that way. The number of them out of 10,000 that said that was precisely zero. No one does that in the real world. That's a mathematical theory that doesn't hold water. And the reason it doesn't hold water is you have not risk adjusted mathematically because you're adding risk to your life. So the typical millionaire, when they hit their first million dollars in net worth, have an $800,000 paid for house and a 7 or $800,000 401k and they were sitting on a million and a half and their house is paid for. And that's the typical millionaire. Like it was stereotypical. There were so many of them, it was crazy in that study, in that piece of research. So what you left out was the fact that when you have no mortgage or you've got a rapidly reducing mortgage, there's more peace in your life. Your career choices are better, your relationships are enhanced, your phys physical body doesn't carry the stress with it and so you don't have stress related diseases. All of these things play into your finances and none of that was in your formula. Hey, you got to take care of your vehicle if you want to keep it on the road.

Up to a $250 value.

[Dave Ramsey]

See store for details. All of these things play into your finances and none of that was in your formula.

[Brandon (Caller)]

So looking at it, you're saying including the risk adjusted returns long term, you're saying if you have the, you know, 30 year fixed mortgage, you're going to be a lot safer with that known variable and it continuing to decrease over time.

[Dave Ramsey]

A 15, 15 year fixed rate mortgage. But yeah, getting rid of, getting rid of the mortgage as fast as I.

[Brandon (Caller)]

Guess, yeah, going in my second question, which I am a long time listener, so I assume you have an opinion on this but wanted to kind of specify our exact situation. So we're touring some new construction, their townhomes, they're smaller homes that we plan to be at for call it four to five years max. We're 26 now. We want to start having children in four or five years. Hopefully we get something a little bigger by then if our income continues to increase, which is our plan. What we have been seeing a lot of in our area is people doing a five year ARM due to the fact that interest rates are currently relatively high with the assumption from the Fed that they'll slightly decrease over the next few years. If we're planning on only being the house for call it five years or less. What a five year ARM ever makes sense in that situation?

[Dave Ramsey]

No, because you don't know what's going to happen. You don't know what you do.

[Brandon (Caller)]

Again, just playing the safe route.

[Dave Ramsey]

You have, you have a plan, but your plan is not going to unfold the way you think. One of two things is going to happen. It's going to, you're going to get wealthy faster, faster than you thought or you're going to have some kind of blocker come up, some kind of problem come up that's going to slow down something and you may end up in that house for a little while longer than you thought. So nothing works out exactly the way you think it's going to. And so you put together things that are sustainable and they're not based, that don't add extreme risk to your situation. So in other words, what I've talked to over the years, Brandon, and 35 years of doing this is I've talked to a number of couples who did something like you're talking about and, and then they think the ARM is coming up and adjusted and then they had a child that had some needs and they weren't able to continue with their income increases for a period. Of time because they had to take care of the kids needs and they get stuck and then they get hammered. The thing adjusts and they can't afford to stay and they end up selling the house to keep from losing it and become a renter again because they took a step back in the mother may I game because they moved forward without permission. If you remember that old time.

[Rachel Cruze]

Yeah. And Brandon, let me encourage you. I mean, you're obviously a well thought out guy. You're trying to look at the past the least resistance in your head. I hear what you're doing. You know, you're looking out this angle.

[Brandon (Caller)]

Yeah.

[Rachel Cruze]

But I just wanna encourage you, Brandon, what's gonna make you guys win with money? It's you guys. It's not these like small. We're gonna finagle the system and get this and that. I'm not kidding. If you just do really boring common sense stuff with money, live on less than you make, don't carry debt, invest in the. Invest in your retirement, pay off your house early and you guys make an insane income and you just do those things.

[Dave Ramsey]

That's all you gotta do.

[Rachel Cruze]

That's all you have to do. And so you don't have to.

[Dave Ramsey]

You don't have to try to shave a half a point here.

[Rachel Cruze]

Yeah. So this is.

[Dave Ramsey]

Optimize a quarter of a point there.

[Rachel Cruze]

Yeah. So Ramsey is. I mean, like our principles and what we talk about on the show, because you've listened, it's pretty boring to guys like you. There's other podcasters out there and they're finagling this and this and okay, we can get the spread here. And they're doing this. I mean, but the amount of mental calories and how it actually ends up really, truly working long term doesn't end up like that. And so people that follow this plan while boring. Right. It's not exciting. It's not the new thing. The amount of peace you're solving for peace. This is what it is. And when you do that and you do common sense things and you don't try to make it all complic. Complicated. It's. It's an enjoyable life. It really is.

[Dave Ramsey]

You're obviously.

[Rachel Cruze]

I hear you. I hear what you're. What you're saying and what you're doing. And I get it. And I think there's like the math nerds out there and they love this stuff. But I'm telling you, people that win with money, long term, it's them, they're the reason they win. It's not this system that you kind of rig here or there.

[Dave Ramsey]

Yeah. To verify that, Rachel. Brandon, you're obviously brilliant. I mean, the questions, the way you formed.

[Rachel Cruze]

It's very thought out.

[Dave Ramsey]

The way you even formed your sentences, you actually know what you're talking about, which is rare. Sometimes I get people asking these questions that you're asking and they don't know what they're actually saying. They just heard it on TikTok. But you actually know what you're talking about. And that's gonna work against you if you're not real careful. You're gonna analyze your way into paralysis of the analysis if you're not careful. So do that. So I'll give you another example of what Rachel's talking about, Brandon, and the data. Because what we keep following is the data of what actually works, not the theory of a think tank.

[Rachel Cruze]

Math.

[Dave Ramsey]

It's not math. Think tank. Okay, so here's the data. The people that end up with a million dollars in their 401 did not pick, on average, did not pick the best possible mutual funds. They picked a subpar mutual fund. There were plenty of funds that outperformed what they picked. Now, they didn't pick the bottom 20%, but they didn't pick necessarily the top 20% of funds out there. They were somewhere around that 80 percentile. And so I'm looking at that going, you missed it. You missed it. Because I'm a math nerd like him, right? And what the data says, and this is that what they find is that what they did do is exactly what you're talking about. They weren't that great at picking the right fund, but what they did do was they never missed a month. Consistency forever. No matter what. They put money in their 401k every stinking month. Prom dress, transmission goes out, kids, sick, dogs got cancer. Every month. They put money in every month.

[Rachel Cruze]

Market's up, market's down.

[Dave Ramsey]

What they didn't underperform in was consistency. They over indexed on consistency and they under indexed on fund choice. And that's an example of what you're talking about. They really weren't that mathematically savvy or mutual fund savvy. They just were consistent versus the amount.

[Rachel Cruze]

Of people that don't do anything. And they have theories of what they may want to do, but they never.

[Dave Ramsey]

Try this little thing and then they try this other little thing and then they try this. And they're always scheming and scamming, trying to cut a half.

[Rachel Cruze]

Yeah, and it's the same thing about paying off the house. We get that call all the time of people have, you know, $80,000 left on their mortgage, and they got 90,000 sitting in some fund over here. And they're like, yeah, but I could be making X amount. And the amount of people we've had at live events, people here, I mean, that were around that we asked the question, those of you that paid off your house, raise your hand and we'll have it. We'll have an auditorium of 2,000 people. And at some of these events, it's like 5, 600. It's. Yeah, I mean, there's a lot of them. And we say, okay, keep your hand up. If you regretted it, who regretted paying off their house?

[Dave Ramsey]

None.

[Rachel Cruze]

None.

[Dave Ramsey]

Zero.

[Rachel Cruze]

Never. So again, that's not in a formula, but I'm telling you, like, when you solve for peace, as Dr. John Deloney says, with your money, that is worth it. That's worth the small percentage point here or there, because you have peace and you sleep good at night, and you have a happy family and a wonderful new marriage, little babies, and it's great. And it's great.
