For decades, first-time homebuyers have heard some version of this advice:
“Don’t buy until you have 20% for the down payment.”
Putting 20% down can absolutely have advantages.
But it is not a universal requirement—and it is not automatically the smartest choice for every buyer.
In fact, waiting until you have exactly 20% saved can sometimes delay homeownership unnecessarily, while using nearly all of your savings to reach 20% can leave you financially vulnerable after closing.
The better question is:
How much should you put down based on your loan options, monthly payment, savings, and personal comfort level?
Why Is 20% Such a Common Number?
The 20% number is closely associated with conventional mortgage financing.
With many conventional loans, borrowing more than 80% of the home’s value means mortgage insurance is required.
Fannie Mae, for example, generally requires primary mortgage insurance on a conventional first mortgage with a loan-to-value ratio above 80%.
That is why 20% became such a familiar benchmark.
Put 20% down and your starting loan-to-value ratio is generally 80%.
Put less down and private mortgage insurance—or another form of credit enhancement depending on the loan structure—may be required.
But that does not mean putting less than 20% down is necessarily a bad idea.
What Is Private Mortgage Insurance?
Private mortgage insurance, commonly called PMI, protects the lender if the borrower defaults.
It does not protect the homeowner.
For many conventional borrowers putting less than 20% down, PMI becomes one component of the monthly housing expense.
The amount can vary based on factors such as:
- Credit profile
- Down-payment amount
- Loan-to-value ratio
- Loan characteristics
- Mortgage insurer
The Consumer Financial Protection Bureau notes that buyers putting between 5% and 19% down will often face PMI or potentially higher rates or fees, while also cautioning buyers against draining all of their savings simply to reach a 20% down payment.
That last point matters.
Avoiding PMI Is Good—but It Isn’t the Only Goal
Suppose you are buying a $500,000 home.
Twenty percent down would be:
$100,000
Five percent down would be:
$25,000
That is a difference of:
$75,000
Putting $100,000 down would reduce your loan balance and may eliminate PMI on a conventional loan.
Those are meaningful benefits.
But what if you only have $110,000 saved?
After putting $100,000 down, you would still need money for:
- Closing costs
- Property taxes and insurance
- Moving
- Repairs
- Furniture
- Emergency savings
Suddenly the supposedly “safer” 20% down payment may leave you with almost no financial cushion.
That is why down-payment decisions should not be made in isolation.
Cash Reserves Have Real Value
Being a homeowner means being responsible for expenses that your landlord previously handled.
Sooner or later, something will break.
It may be:
- A water heater
- Refrigerator
- Plumbing
- Air conditioner
- Roof
- Electrical system
- Appliance
Or the unexpected expense might have nothing to do with the house.
Your car may need repair.
Your income could temporarily drop.
You may have a medical expense or family emergency.
Having money available after closing can be enormously valuable.
I would rather see a buyer understand the tradeoff between a larger down payment and healthy reserves than automatically assume that every available dollar belongs in the house.
Compare the Monthly Payment
The right way to evaluate 20% down is to compare actual financing scenarios.
Ask your lender to show you something like:
Scenario A: 20% down
versus
Scenario B: 10% down
versus
Scenario C: 5% down
Then compare:
- Total cash required
- Loan amount
- Interest rate
- Principal and interest
- Mortgage insurance
- Total monthly housing payment
- Cash remaining after closing
Now you have something useful to evaluate.
For example, you may discover that putting an additional $40,000 down only reduces the monthly payment by an amount that is not worth giving up $40,000 of liquidity.
Or you may discover the opposite—the payment savings are substantial enough that the larger down payment makes sense.
There isn’t one correct answer for everyone.
Think About What the Extra Down Payment Actually Buys You
This is an especially useful question.
Suppose increasing your down payment from 10% to 20% requires another $50,000.
Ask:
What am I receiving in exchange for that $50,000?
You may receive:
- A smaller loan
- A lower monthly principal-and-interest payment
- No PMI on a conventional loan
- Possibly different pricing or loan options
- More equity from day one
Those are real benefits.
Then ask:
What am I giving up?
Potentially:
- Emergency reserves
- Investment funds
- Money for repairs
- Moving funds
- Financial flexibility
The decision becomes much clearer when you evaluate both sides.
A Bigger Down Payment Can Help With Qualification
There are also situations where putting more money down can make the loan work.
A larger down payment reduces the loan amount.
That generally reduces the principal-and-interest payment.
A lower monthly payment can improve your debt-to-income ratio and potentially help you qualify.
A larger down payment may also help if:
- Your income is close to the qualifying limit
- You are purchasing near the top of your price range
- The property type has stricter financing requirements
- The loan program has particular loan-to-value limitations
So there are cases where 20%—or even more—can be strategically useful.
But Don’t Use 20% Just Because Someone Told You To
This is where first-time buyers can get stuck.
They may have heard from parents or friends:
“Never pay mortgage insurance.”
That sounds reasonable until you look at the actual numbers.
Suppose reaching 20% requires you to wait another three years.
During those three years:
- Home prices may change
- Interest rates may change
- Your rent may increase
- Your income may change
- Your preferred market may change
Nobody can know in advance whether waiting will ultimately be better or worse.
The point is not that you should rush to buy.
It is that “I don’t have 20% yet” should not automatically end the conversation.
Find out what your real alternatives are.
Could You Put Less Down and Pay PMI Temporarily?
Potentially.
Private mortgage insurance on a conventional loan does not necessarily remain forever.
Depending on the loan and circumstances, it may eventually be cancelled or terminate as equity increases and applicable requirements are met.
So instead of thinking:
“If I put 10% down, I will pay PMI for 30 years,”
ask your lender how mortgage insurance works on the specific loan being proposed.
Then compare the cost of PMI with the benefit of keeping more of your savings.
Low Down Payment Does Not Mean You Should Buy the Maximum
There is another trap worth avoiding.
If a program allows you to buy with a small down payment, that does not mean you should automatically purchase the most expensive home for which you qualify.
Your down payment and your comfortable monthly payment are two different questions.
You still need to account for:
- Property taxes
- Homeowners insurance
- Mortgage insurance
- HOA dues
- Maintenance
- Utilities
- Other monthly debts
The right home price is one that fits your life, not simply the maximum your loan approval permits.
Could Gift Funds Help You Reach 20%?
Possibly.
Depending on the loan program, eligible gift funds may be used toward some or all of your down payment.
Under current Fannie Mae guidelines, eligible gift funds can fund all or part of the down payment and closing costs on qualifying principal-residence transactions, subject to applicable requirements.
That could allow a buyer to reach a larger down payment without exhausting their own savings.
But again, the question should remain:
Does reaching 20% actually improve the overall financing enough to make it worthwhile?
Don’t choose the percentage first and then force your finances to fit it.
Don’t Forget About Closing Costs
If you have $100,000 saved and are buying a $500,000 home, you do not necessarily have a 20% down payment available.
You have $100,000 total.
You may still need cash for:
- Closing costs
- Prepaid taxes
- Homeowners insurance
- Escrow deposits
- Appraisal or inspection expenses
- Moving expenses
There may also be seller credits, lender credits, gift funds, or assistance that change those numbers.
That is why your lender should estimate your total cash needed to close, not merely your down payment.
What About FHA, VA, and Other Loan Programs?
Not every mortgage is structured around a 20% down payment.
Different programs can provide substantially different options.
Depending on borrower and property eligibility, buyers may consider conventional, FHA, VA, and other financing programs.
Each has its own:
- Down-payment requirements
- Mortgage-insurance or guarantee structure
- Credit guidelines
- Property requirements
- Costs
The lowest down payment is not automatically the best loan.
And the largest down payment is not automatically the best loan either.
Compare the complete package.
Mobile and Manufactured Homes Are Different Again
Manufactured and mobile-home financing can have a very different down-payment structure.
If a manufactured home and the land are financed together as real estate, traditional mortgage programs may apply.
But homes located on leased land are often financed as personal property using a chattel loan.
With certain chattel programs, qualified borrowers purchasing eligible manufactured homes built June 15, 1976 or later may have financing options starting around 5% down.
That does not mean every buyer or every home qualifies for 5% down.
Credit, income, property age and condition, loan size, park requirements, and the particular lender all matter.
But it illustrates why the old statement:
“You need 20% down to buy a home.”
can be especially misleading for mobile-home buyers.
Personal-property lenders also set their own underwriting requirements, which can differ considerably from traditional mortgage programs.
When Might 20% Down Make Sense?
A 20% down payment may be particularly attractive when:
- You can comfortably afford it without draining savings
- Eliminating PMI meaningfully improves your monthly payment
- You want the smallest practical mortgage balance
- A lower payment improves qualification
- You still have healthy reserves afterward
- The financing terms improve enough to justify the additional cash
In those circumstances, 20% can be a very good choice.
When Might Putting Less Down Make Sense?
A smaller down payment may be worth considering when:
- Reaching 20% would wipe out most of your savings
- You need reserves for repairs or emergencies
- You qualify for an attractive low-down-payment program
- The monthly payment remains comfortable
- PMI is manageable
- You want to preserve cash for other financial goals
- Waiting for 20% would delay a purchase you are otherwise financially prepared to make
Again, none of these automatically makes a smaller down payment better.
They simply mean it deserves consideration.
The Better Question Isn’t “Can I Put 20% Down?”
Ask:
“What happens if I do?”
Then compare that against putting less down.
A good loan comparison should show you:
- Cash needed at closing
- Monthly payment
- Mortgage insurance
- Loan terms
- Cash remaining after closing
Once you see those numbers side by side, the decision is usually much easier.
Don’t Let an Arbitrary Number Keep You From Exploring Your Options
If you have 20% available and putting it down leaves you financially comfortable, great.
If you don’t have 20%, that does not necessarily mean you aren’t ready to buy.
And if you technically can put 20% down but doing so would leave you with almost nothing in the bank, there may be a better approach.
The goal is not to achieve a particular down-payment percentage.
The goal is to structure the purchase so that both the monthly payment and your remaining savings make sense for you.
