# How Much Down Payment Do You Actually Need to Buy a House?

Not 20% — that rule is decades out of date, and waiting for it can cost more than it saves. Here's what each down payment really costs you at today's 6.69% mortgage rate.

The 20% down payment is the most expensive piece of folk wisdom in personal finance. Not because it's bad advice — 20% is genuinely useful — but because millions of people treat it as the *entry requirement*, decide they're years away from qualifying, and stop looking.

You do not need 20% down to buy a house. Most buyers don't put down anywhere near it. The real minimum for a conventional loan is **3%**, some government-backed loans go to **zero**, and the honest answer to "how much do I need?" is a trade-off rather than a threshold.

Here's what each option actually costs, using a **$400,000** home and today's 30-year rate of **6.69%**.

## The actual minimums

**Conventional loans — as low as 3% down.** The standard mortgage most buyers get. Several first-time-buyer programs allow 3%; 5% is common without them. You'll pay private mortgage insurance until you build enough equity, which we'll get to.

**FHA loans — 3.5% down.** Backed by the Federal Housing Administration and considerably more forgiving on credit history, which is often the real reason people use them. The catch is the mortgage insurance, which is structured less kindly than the conventional version — if you put down less than 10%, it typically stays for the life of the loan, and the only way off it is a refinance.

**VA loans — 0% down.** For eligible veterans, active-duty service members, and some surviving spouses. No down payment, no ongoing mortgage insurance at all, and generally competitive rates. If you qualify for a VA loan, it is very hard to beat, and it's worth checking eligibility before assuming you don't.

**USDA loans — 0% down.** For moderate-income buyers in eligible rural and many suburban areas. The maps cover more ground than "rural" suggests; check before you dismiss it.

So the floor is much lower than folklore says. The question is what the floor costs.

## What each down payment actually costs, month to month

Same $400,000 house, same **6.69%** rate, same 30-year term. Only the down payment changes:

| Down payment | Cash at closing | Loan amount | Monthly principal & interest |
|---|---|---|---|
| 3% | $12,000 | $388,000 | **$2,501** |
| 5% | $20,000 | $380,000 | **$2,450** |
| 10% | $40,000 | $360,000 | **$2,321** |
| 20% | $80,000 | $320,000 | **$2,063** |

Note what this table does and doesn't show. Going from 3% to 20% requires **$68,000 more cash** and saves about **$438 a month** in principal and interest. That's a real saving — but it takes roughly a decade of that saving just to recover the extra cash you handed over at closing, ignoring what that cash could have earned elsewhere.

These figures are principal and interest only. Property taxes, homeowners insurance, and any HOA dues sit on top, and they're not small — in many places they add 25–40% to the payment.

## PMI: the cost of putting down less

Put down less than 20% on a conventional loan and you'll pay **private mortgage insurance**. It's worth understanding precisely, because it's the thing people fear most and understand least.

PMI protects the *lender*, not you, against the possibility you default. It typically runs somewhere around 0.3% to 1.5% of the loan per year depending on your credit and down payment — on that $380,000 loan at 5% down, a mid-range rate works out to roughly **$158 a month**.

The critical part: **on a conventional loan, PMI is temporary.** Once you reach 80% loan-to-value you can request it be removed, and at 78% the lender must drop it automatically. You get there through your own payments, through the home appreciating, or both. So the realistic framing isn't "PMI forever versus no PMI" — it's "a few hundred dollars a month for a handful of years versus waiting years to buy."

That's a genuine trade, and which side wins depends on your market, not on principle.

## What 20% actually buys you

None of this makes 20% pointless. It buys four real things:

1. **No PMI**, immediately.
2. **A smaller loan**, so a lower payment and dramatically less total interest — check the difference over the full term with the [amortization calculator](https://digestyourfinances.com/tools/amortization-calculator/).
3. **Often a slightly better rate**, since lenders price risk.
4. **Instant equity**, which is your buffer if prices dip. Buying with 3% down in a market that falls 10% puts you underwater — owing more than the house is worth — and that's not a paper problem if you need to sell or refinance.

That last one is the argument that deserves the most respect. A larger down payment isn't just cheaper; it's *safer*.

## So how do you decide?

The real question is not "have I hit 20%?" It's **"what does waiting cost me?"**

Waiting to save a larger down payment makes clear sense when: you're close already, your rent is cheap, prices in your market are flat or falling, and every month of saving meaningfully moves the number.

Buying sooner with less down makes more sense when: your rent is high and rising, prices in your area keep climbing faster than you can save, you're stable in your job and plan to stay put for years, and the payment fits comfortably at *today's* rate — not at some hoped-for future rate.

Three guardrails, regardless of which side you land on:

- **Don't drain your emergency fund into the down payment.** A house generates surprise expenses immediately, and the worst version of homeownership is owning one with no cash. Lenders often want to see reserves anyway.
- **Judge affordability by the full monthly payment**, taxes and insurance included, not by the price tag. Our [home affordability calculator](https://digestyourfinances.com/tools/affordability/) uses the 28/36 rule lenders actually apply.
- **Improve your credit before you shop.** A better score can move your rate more than an extra few percent down moves your payment. Start with [how to boost your credit score](https://digestyourfinances.com/boost-your-credit-score/).

## The costs that aren't the down payment

This is where first-time buyers get ambushed. The down payment is not the cash you need — it's the largest piece of it.

**Closing costs** typically run 2–5% of the purchase price: origination, appraisal, title insurance, recording fees. On a $400,000 home that's $8,000 to $20,000, due at the same moment as the down payment.

**Escrow prepaids.** Lenders collect several months of property taxes and insurance up front to seed your escrow account. If you've never dealt with one, [what is escrow](https://digestyourfinances.com/what-is-escrow/) explains where that money goes.

**Inspection, moving, and the immediate repairs.** Nothing about the first month in a house is free.

Budget for all of it before you decide how much to put down. The full list is in [the hidden costs of buying a home](https://digestyourfinances.com/home-buying-hidden-costs/).

## Where to keep the money while you're saving

A down payment you'll use within a few years has no business in the stock market. A 20% drop three months before closing is not a hypothetical — it's happened to plenty of buyers. Keep it somewhere safe and liquid that still earns: a high-yield savings account, or Treasury bills timed near your target date.

## Quick answers

**Do I need 20% down?** No. Conventional loans go to 3%, FHA to 3.5%, and VA and USDA to zero for those who qualify.

**Is PMI a waste of money?** It buys you nothing directly — but it can buy you years of ownership you'd otherwise spend renting. On a conventional loan it also ends. Compare it against your rent, not against zero.

**Does a bigger down payment get me a better rate?** Usually a slightly better one, yes. The effect is real but smaller than most people expect — your credit score generally moves the rate more.

**Should I put down more than 20%?** Rarely worth it unless you're specifically chasing a lower payment and have no better use for the cash. Once PMI is gone, extra dollars are just prepaying a fixed-rate loan, which competes with investing them.

**Is buying even the right call?** A fair question, not a rhetorical one. Run it through the [rent vs buy calculator](https://digestyourfinances.com/tools/rent-vs-buy/) and read [is buying a home a good investment](https://digestyourfinances.com/is-buying-a-home-a-good-investment/).

## The bottom line

The 20% rule is a good target, not a gate. At **6.69%**, the difference between 3% down and 20% down on a $400,000 house is **$68,000** in cash for about **$438** a month — a trade worth making if you have the money sitting idle, and worth skipping if chasing it means five more years of rising rent and rising prices.

Work out what you can genuinely afford monthly, confirm you'll still have cash after closing, and then put down whatever gets you there without emptying you out. That number is different for everyone, and it is almost never exactly twenty percent.
