If you’ve been around real estate long enough, you’ve probably heard both sides of the down payment debate. One camp says 20% down is an outdated rule of thumb, a relic from an era when lending options were limited. The other insists it’s still the gold standard. So which is it?
Here’s the truth: you do not need 20% down to buy a home today. Plenty of loan programs let qualified buyers purchase with far less — some conventional loans allow 3% down, FHA loans start at 3.5%, and VA and USDA loans can require nothing at all. For many first-time buyers, those low-down-payment options are the very thing that makes homeownership possible, and there’s no shame in using them.
But if you’re a move-up buyer — someone selling one home to purchase the next — the math changes dramatically. And that’s why so many repeat buyers still choose to put 20% or more down, even when nobody is forcing them to. In fact, data from the National Association of Realtors shows repeat buyers typically put down roughly 23% of the purchase price, while first-time buyers tend to land closer to 10%.
That gap isn’t an accident. It reflects two things: repeat buyers usually can put more down, and they’ve learned that doing so pays off. Let’s walk through both.
Where Does a 20% Down Payment Come From?
For most repeat buyers, the answer is simple: their current home.
Every month you make a mortgage payment, a portion of it chips away at your loan balance. At the same time, home prices have generally appreciated over the years you’ve owned. Those two forces — principal paydown and appreciation — combine into home equity, the difference between what your house is worth and what you still owe on it.
For longtime homeowners, that equity can be substantial. If you bought your home five, ten, or fifteen years ago, you may be sitting on more wealth than you realize. When you sell, that equity converts to cash at the closing table — cash that can go straight toward the down payment on your next home.
This is the piece many move-up buyers overlook. They look at today’s prices, mentally calculate 20% of a big number, and feel discouraged. But they’re forgetting that they’re not starting from zero the way they did the first time around. A quick conversation with a real estate agent about your home’s current market value — and a payoff estimate from your lender — can tell you exactly how much buying power you’ve built up.
The Four Big Advantages of a Larger Down Payment
Once you know you can put 20% down, the next question is whether you should. Here are the four main reasons a bigger down payment works in your favor.
1. A Lower Monthly Payment
This one is straightforward: the more you put down, the less you borrow, and the less you borrow, the smaller your monthly payment. In a market where affordability is on everyone’s mind, shrinking the loan is one of the most direct ways to shrink the payment.
Consider a $400,000 home as an example. Putting 20% down instead of 10% means borrowing $320,000 instead of $360,000. On a 30-year fixed loan at a 6.5% rate, that $40,000 difference trims roughly $250 off the payment every single month — before you even factor in mortgage insurance savings. Over a year, that’s about $3,000 back in your budget for savings, travel, renovations, or simply breathing room.
2. Less Interest Paid Over the Life of the Loan
Interest is the quiet cost of borrowing, and it adds up to far more than most people expect. Because interest is charged on your outstanding balance, a smaller loan means you pay less of it — every month, and cumulatively over decades.
Using that same $400,000 example, the buyer who borrows $320,000 instead of $360,000 could save around $50,000 in total interest over a 30-year term. That’s not a rounding error; it’s a college fund, a retirement boost, or years’ worth of property taxes. The larger down payment essentially buys you a discount on the true cost of your home.
3. No Private Mortgage Insurance
When you put down less than 20% on a conventional loan, lenders typically require private mortgage insurance, or PMI. Here’s the important thing to understand about PMI: it protects the lender, not you. You pay the premium, but you receive no direct benefit from it.
PMI commonly runs somewhere between 0.5% and 1% of the loan amount per year, which on a $360,000 loan could mean an extra $150 to $300 tacked onto your payment each month. Cross the 20% threshold and that expense disappears entirely. For buyers who have the equity to avoid it, PMI is simply a cost with no upside — and skipping it is one of the cleanest wins in the whole transaction.
4. A Stronger, More Competitive Offer
This advantage gets less attention, but in a competitive market it can be the difference between winning a home and losing it. Sellers and their agents pay close attention to the financial strength behind an offer. A buyer bringing 20% or more to the table signals solid footing: their financing is less likely to fall apart, their appraisal risk is lower, and their lender has more cushion to work with.
When a seller is weighing multiple offers, that confidence matters. All else being equal, the offer backed by a substantial down payment often looks like the safer bet — and sellers reward safety. Your down payment isn’t just a financing detail; it’s part of your negotiating position.
Is 20% Always the Right Move?
Not necessarily — and it’s worth being honest about that. If putting 20% down would drain your emergency fund, leave you nothing for moving costs and repairs, or force you to sell investments at a bad time, a smaller down payment with cash in reserve may be the wiser play. A house with an empty savings account behind it can feel more stressful than a slightly higher payment.
The point isn’t that everyone must hit 20%. The point is that if you’ve built meaningful equity in your current home, you likely have options your first-time-buyer self never had — and using that equity strategically can make your next purchase more affordable, less expensive over time, and more competitive.
Your Next Step
Before you assume anything about what you can or can’t afford, get real numbers. Ask a local real estate agent for a professional assessment of what your current home would sell for in today’s market. Then talk with a trusted lender who can show you side-by-side scenarios: what your payment, interest costs, and cash position would look like at different down payment levels.
You might be pleasantly surprised. The equity you’ve spent years building could be the key that unlocks a stronger financial position on your next home — lower payments, tens of thousands saved in interest, no PMI, and an offer sellers take seriously.
The 20% down payment isn’t a requirement. For move-up buyers, it’s something better: an opportunity.
