If you've ever talked about buying a home with friends, family, or coworkers, someone has probably told you that you need 20% down.

It gets repeated so often that many people treat it as a rule. Some buyers even delay their home search for years because they assume they can't move forward without it.

A 20% down payment is not a requirement. It's a benchmark that comes with some advantages, but plenty of people buy homes with far less.

Understanding where the 20% number comes from, and what your actual options are, can help you make a decision based on your finances instead of someone else's rule of thumb.

Where the 20% Rule Comes From

The 20% figure isn't arbitrary, but it's also not a requirement.

Lenders view a 20% down payment as the threshold where a borrower has enough equity in the home that the loan is considered lower risk. Put down less than that on a conventional loan, and the lender typically requires private mortgage insurance (PMI) to protect themselves if you default.

Over time, that lending standard turned into the public perception that "you need 20% down to buy a house."

According to the National Association of Realtors, the typical down payment for first-time homebuyers has hovered around 8% to 9% in recent years. Repeat buyers put down more, often in the high teens, largely because they're rolling equity from a previous home into the next one.

In other words, most first-time buyers are not putting 20% down.

The Case for Putting 20% Down

Even though it's not required, a 20% down payment has benefits. If you can comfortably reach that number, it can be a good idea.

You Avoid PMI

Private mortgage insurance typically costs between 0.3% and 1.5% of your loan amount per year, depending on your credit score and down payment size.

On a $400,000 loan, that could mean anywhere from $100 to $500 per month added to your payment. That money protects the lender, not you. So if it's possible to avoid it, that can be a good thing.

Your Monthly Payment Is Lower

A bigger down payment means a smaller loan. A smaller loan means a lower monthly payment and less interest paid over the life of the mortgage.

On a 30-year loan, the difference between putting 10% and 20% down on a $450,000 home can easily amount to tens of thousands of dollars in interest over time.

You Start With More Equity

Equity is your ownership stake in the home. Starting with 20% gives you a cushion if home values dip.

Buyers who purchased with small down payments right before a market decline can find themselves underwater, meaning they owe more than the home is worth. That's not a crisis if you plan to stay put, but it limits your flexibility if you need to sell, refinance, or borrow against your equity (like a HELOC or a Home Equity Loan).

Your Offer May Look Stronger

In competitive markets, sellers and their agents sometimes view larger down payments as a signal that financing is less likely to fall through. It's not a guarantee of anything, but it can help.

The Case Against Waiting for 20%

Here is where it makes sense to consider your specific personal situation over general rules of thumb. For many buyers, waiting until they have 20% saved is actually the more expensive choice.

Home Prices May Rise Faster Than You Can Save

Say you're targeting a $400,000 home and you have $20,000 saved. Getting to 20% means saving another $60,000.

If that takes you four years and home prices rise 4% annually during that stretch, your target home now costs around $468,000. Your 20% goal just moved to $93,600. You spent four years chasing a number that kept running away from you.

Meanwhile, you paid rent the entire time and built no equity.

PMI Isn't Permanent

Many people treat PMI like a life sentence. But it's not permanent.

On conventional loans, you can request PMI cancellation once you reach 20% equity, and lenders are required to remove it automatically at 22% equity. Between your regular payments and home appreciation, many buyers get rid of PMI within a few years.

Paying $150 a month in PMI for three or four years might be a reasonable price for getting into a home sooner and starting to build equity now.

Draining Your Savings Creates a Different Risk

Pulling together 20% by emptying your emergency fund is a mistake I see often.

Homes come with surprise expenses. A furnace fails, a roof leaks, a water heater gives out. New homeowners who put every dollar into the down payment often end up funding those repairs with credit cards.

A smaller down payment with a healthy cash reserve is frequently the more stable position, even if it means paying PMI for a while.

Opportunity Cost

Every dollar in your down payment is a dollar not invested elsewhere. Depending on mortgage rates and market conditions, the math on putting extra money toward a home versus keeping it invested isn't always obvious.

This doesn't mean you should minimize your down payment to maximize investing. It means the decision deserves actual analysis rather than a default assumption.

What Your Down Payment Options Actually Look Like

The range of legitimate down payment options is wider than most people realize.

Conventional Loans With 3% to 5% Down

Many conventional loan programs allow qualified buyers to put down as little as 3%. Fannie Mae and Freddie Mac both back programs designed for this.

You'll pay PMI, and your rate may be slightly higher, but these loans are common and widely available to buyers with solid credit.

FHA Loans With 3.5% Down

FHA loans, backed by the Federal Housing Administration, allow down payments as low as 3.5% for borrowers with credit scores of 580 or above.

The tradeoff is that FHA loans carry their own mortgage insurance premiums, which in many cases last for the life of the loan unless you refinance. They can still make sense for buyers with lower credit scores or limited savings, but the long-term insurance cost is something to consider.

Side note: back in the day, I bought my first home with an FHA loan, and it was a great decision for me.

VA Loans With 0% Down

If you're a veteran, active-duty service member, or eligible surviving spouse, VA loans allow you to buy with no down payment at all and no monthly mortgage insurance.

There's an upfront funding fee, but VA loans are consistently among the best financing deals available for those who qualify.

USDA Loans With 0% Down

USDA loans offer zero-down financing for homes in eligible rural and some suburban areas, subject to income limits. Fewer people qualify, but for those who do, it's worth exploring.

Down Payment Assistance Programs

Many states, counties, and cities offer down payment assistance in the form of grants, forgivable loans, or low-interest second mortgages. These programs often target first-time buyers or buyers under certain income thresholds.

These programs are underused simply because people don't know they exist.

How to Think About the Right Down Payment for You

Instead of asking "how do I get to 20%," ask a better set of questions.

How Much Can You Put Down Without Sacrificing Stability?

Your down payment should leave you with an intact emergency fund, ideally three to six months of expenses, plus a buffer for closing costs, moving expenses, and the inevitable early repairs and purchases a new home brings.

Whatever is left after protecting those priorities is your realistic down payment range.

What Does the Monthly Payment Look Like at Each Level?

Run the numbers at 5%, 10%, and 20% down. Include PMI where it applies.

Then ask whether each monthly payment fits comfortably within your budget. A common guideline is keeping total housing costs below 28% of gross income, though your personal situation matters more than any ratio.

How Long Do You Plan to Stay?

If you expect to be in the home for a decade, temporary PMI and a smaller equity cushion matter less. Time smooths out most of the risk.

If there's a real chance you'll move within three or four years, a larger down payment provides protection against selling in a down market.

What Would Waiting Actually Cost?

Compare the cost of PMI and higher interest against the cost of continued rent and potential price appreciation while you save. In many markets, buying sooner with less down comes out ahead. In others, waiting is smarter.

This is a math problem, not a philosophy question. Do the math for your market and your numbers.

Your Situation Is the Only One That Matters

The 20% rule persists because it's easy to repeat. But easy to repeat and right for you are not the same thing.

Some buyers should absolutely put 20% down. They have the savings, a strong emergency fund, and the equity cushion aligns with their goals.

Other buyers are better served putting less down, keeping their reserves intact, and getting into a home years earlier than the 20% crowd told them was possible.

Before you commit to a down payment, look at your full financial picture. Your income stability, your savings, your other goals, and your timeline all factor into what makes sense.

Frequently Asked Questions

Is 20% down required to buy a house?

No. Conventional loans allow as little as 3% down for qualified buyers, FHA loans require 3.5%, and VA and USDA loans offer zero-down options for eligible borrowers. The 20% figure is only the threshold for avoiding private mortgage insurance on conventional loans.

What is PMI and how much does it cost?

Private mortgage insurance protects the lender if you default on a conventional loan with less than 20% down. It typically costs 0.3% to 1.5% of your loan amount annually, added to your monthly payment. Your credit score and down payment size affect the rate.

Can I get rid of PMI later?

Yes. On conventional loans, you can request cancellation once you reach 20% equity in the home, and lenders must automatically remove it at 22% equity. Home appreciation can accelerate this timeline, sometimes allowing removal after a new appraisal.

Is it better to put 20% down or keep the money invested?

It depends on mortgage rates, your expected investment returns, your risk tolerance, and how much liquidity you need. There's no universal answer, which is exactly why this decision benefits from analysis specific to your situation rather than a rule of thumb.

What credit score do I need to buy with a low down payment?

Conventional low-down-payment programs generally look for scores of 620 or higher, with better pricing at 740 and above. FHA loans allow scores as low as 580 with 3.5% down. Higher scores reduce both your interest rate and your PMI cost.

Should I use all my savings for a bigger down payment?

Generally, no. Keeping an emergency fund of three to six months of expenses, plus a reserve for home repairs and moving costs, usually matters more than a larger down payment. A home purchase that leaves you cash-poor creates risk that outweighs the PMI savings.

How much are closing costs on top of the down payment?

Closing costs typically run 2% to 5% of the loan amount, covering items like lender fees, title insurance, appraisal, and prepaid taxes and insurance. Budget for these separately from your down payment so they don't catch you off guard.
