Why Putting 20% Down Isn't Always the Smartest Financial Decision
For a lot of homebuyers, 20% down has become the magic number.
Save 20%.
Put 20% down.
Avoid PMI.
Get the best mortgage.
That's the responsible way to buy a house.
Sometimes it is.
But somewhere along the way, "20% down is one option" turned into "20% down is what financially responsible people do."
I don't agree with that.
I've worked with buyers who absolutely should put 20% down.
I've also worked with buyers who could easily put 20% down and chose not to because keeping some of that money available made more sense.
The question isn't whether you can put 20% down.
The better question is:
What does putting 20% down actually accomplish, and what are you giving up to do it?
That's where the conversation gets more interesting.
Why Does Everyone Talk About 20%?
There's a legitimate reason 20% gets so much attention.
On a Conventional mortgage, putting at least 20% down generally allows you to avoid private mortgage insurance, commonly called PMI.
A larger down payment also means:
A smaller loan amount.
A lower monthly principal and interest payment.
More equity in the property from day one.
Potentially better financing terms depending on the loan.
Those are real benefits.
I'm not here to talk you out of putting money down.
I'm here to make sure we're not putting $80,000 into a house just because someone told you that's what you're supposed to do.
You Can Buy a Home With Less Than 20% Down
This surprises more first-time buyers than it should.
Qualified buyers may have Conventional options with significantly less than 20% down.
FHA financing generally allows qualified borrowers to purchase with 3.5% down.
Eligible veterans may potentially purchase using VA financing with no down payment.
There may also be down payment assistance options available to qualifying buyers.
So 20% isn't the entry fee for homeownership.
It's one financing strategy among several.

Let's Put Real Numbers Behind It
Let's say you're buying a $500,000 home.
At 20% down, you'd put down:
$100,000.
At 10% down:
$50,000.
At 5% down:
$25,000.
That's a $75,000 difference between putting 20% down and 5% down.
Obviously, the smaller down payment means you're borrowing more money.
Your monthly principal and interest payment will be higher.
You may have mortgage insurance.
Depending on the loan structure, other pricing differences may apply.
But you also kept $75,000.
That's not a small detail.
Now we have something worth analyzing.
The Question Is What That Extra Money Does for You
If you put the additional $75,000 into the house, that money becomes home equity.
That's valuable.
But home equity and cash in your bank account aren't the same thing.
Once money goes into the property, accessing it again generally means selling the home or qualifying for some form of financing against the equity.
Cash gives you flexibility immediately.
It can serve as:
An emergency fund.
A home repair fund.
Investment capital.
Business reserves.
Money for renovations.
Funds for another real estate purchase.
A cushion during a career change.
Or simply the ability to sleep better at night.
That flexibility has value too.
Home Equity Is Wealth, but It Isn't Very Liquid
This is the part of the down payment conversation I think gets overlooked.
Let's say Buyer A purchases a $500,000 home and puts $100,000 down.
Buyer B purchases the same home and puts $50,000 down.
Buyer A starts with more equity and a lower mortgage balance.
Buyer B starts with less equity and a higher payment, but keeps an additional $50,000 available.
Which buyer is in the stronger financial position?
You can't answer that without knowing the rest of their lives.
If Buyer A still has $200,000 in savings after closing, putting 20% down may be perfectly reasonable.
If Buyer A has $3,000 left after closing, I have more questions.
The down payment doesn't exist in a vacuum.
I Care About What Your Bank Account Looks Like After Closing
This is one of the first things I want to know when we're discussing down payment.
Not just:
"How much money do you have?"
But:
"How much money do you want to have left?"
There's a difference.
Buying a house with $75,000 in reserves feels very different from buying the same house with $2,500 in reserves.
Even if the person with $2,500 has a slightly lower mortgage payment.
You own the roof now.
And the HVAC.
And the water heater.
And the refrigerator.
Homes have an incredible ability to wait until you've spent all your money before informing you that something needs attention.
Having liquidity after closing matters.

But What About PMI?
This is usually the immediate objection.
"If I don't put 20% down, I'm throwing money away on PMI."
Maybe.
But let's actually look at the cost.
Private mortgage insurance protects the lender when a Conventional borrower finances above certain loan-to-value levels.
The cost isn't the same for every borrower.
It can vary based on things like:
Credit profile.
Down payment.
Loan amount.
Loan structure.
Other risk characteristics.
For a borrower with strong credit, PMI may be much less expensive than they expected.
If keeping an additional $50,000 in the bank costs you $90 per month in PMI, that's a conversation worth having.
If it costs $350 per month, that's a different conversation.
The phrase "it has PMI" doesn't tell me enough.
I want the actual number.
PMI Doesn't Necessarily Last Forever
Another reason I don't automatically treat PMI as a deal breaker is that Conventional mortgage insurance may eventually be eligible for cancellation when applicable requirements are satisfied.
That means we shouldn't necessarily compare:
20% down with no PMI
against
10% down with PMI forever.
We should understand how the actual mortgage insurance works, what it costs, and what the potential path to removing it looks like.
If you're buying in a market where the property appreciates over time and you're also paying down the loan, the equity picture can change.
That doesn't mean we should assume appreciation will bail us out.
It means mortgage insurance should be evaluated as part of the full strategy rather than treated as a permanent punishment for putting less than 20% down.
Opportunity Cost Matters
Here's where we get beyond mortgage qualification and into financial planning.
Every dollar has competing uses.
If you put another $50,000 into your down payment, you can't simultaneously keep that same $50,000 in savings.
You can't invest it.
You can't use it to pay off higher-interest debt.
You can't use it as business capital.
You can't use it toward another property.
You can't keep it as an emergency reserve.
That doesn't mean any of those choices are automatically better than putting the money into your home.
It means there is a cost to choosing one over the others.
That's opportunity cost.
And it's one of the reasons I don't believe down payment decisions should be made using a rule of thumb.
Sometimes Paying Off Other Debt Is More Powerful
Let's say you have an extra $25,000.
You could put it toward the house.
Or perhaps you have an auto loan or another debt with a meaningful monthly payment.
Depending on the balances, rates, and your overall financial picture, eliminating another debt could potentially improve your monthly cash flow more than applying that same $25,000 toward the mortgage.
It could also affect your qualification.
Would I automatically tell you to pay off the debt?
No.
I'd compare it.
What happens to your mortgage payment if we put the extra $25,000 down?
What happens to your overall monthly obligations if we eliminate the other debt instead?
How much cash do you have left either way?
Which option gives you the stronger balance sheet?
That's the analysis I care about.
A Bigger Down Payment Doesn't Always Create a Dramatically Lower Payment
Buyers sometimes expect a larger down payment to completely change the monthly payment.
It certainly lowers it.
But remember, you're spreading that additional financed amount over a long mortgage term.
Let's say you're deciding whether to put another $25,000 down.
The question isn't simply:
"Will my mortgage payment go down?"
Of course it will.
The better question is:
"Is the amount my payment decreases worth giving up $25,000 of liquidity today?"
Maybe the answer is absolutely yes.
Maybe it's absolutely no.
Maybe it's close.
That's why we run scenarios.
What If You Invest the Difference?
This is where people can get a little too cute with spreadsheets.
You'll sometimes hear:
"Never put more money down. Invest the difference and you'll earn more."
Maybe.
But investment returns aren't guaranteed, and your personal risk tolerance matters.
I'm not interested in pretending we know exactly what an investment account will earn over the next ten years.
What I am interested in is recognizing that money has alternative uses.
If you're choosing between putting an additional $50,000 into the house and keeping that money invested, that's worth discussing with your financial advisor.
The mortgage shouldn't be built independently from the rest of your financial plan.
For some people, reducing debt is the priority.
For others, liquidity and investable assets are more important.
Both can be reasonable.
What If You're Planning to Buy Another Property?
Now the conversation can change significantly.
Suppose you're buying your first home but already know that real estate investing is part of your long-term plan.
You have $100,000 available.
You could put all $100,000 into your primary residence.
Or perhaps you put less down, maintain sufficient reserves, and keep capital available for a future investment property.
That doesn't mean you should stretch yourself thin just to buy more real estate.
But capital allocation matters.
Putting every available dollar into your primary residence may give you a lower payment today while delaying another goal by several years.
If building a real estate portfolio is important to you, I want to know that before we decide how much money goes into the first house.
Your first mortgage should fit into the bigger plan.
Your Time Horizon Matters Too
How long do you expect to own the home?
How long do you expect to keep this particular mortgage?
Those aren't always the same question.
Maybe this is a starter home you expect to own for four or five years.
Maybe you plan to turn it into a rental later.
Maybe this is the house where you expect to raise your family for the next 20 years.
Maybe your career could move you somewhere else in three years.
The longer you expect to keep the property and mortgage, the more certain upfront decisions may matter differently.
The shorter the expected time horizon, the more careful I want to be about tying up additional cash purely to optimize a mortgage you may not have for very long.
A Lower Down Payment Can Also Make Your Payment Too High
Let's make sure we don't swing too far in the other direction.
Just because you can put 3%, 5%, or 10% down doesn't mean you should.
A smaller down payment means a larger loan.
That generally means a higher monthly principal and interest payment.
There may also be mortgage insurance.
If keeping an extra $50,000 in the bank creates a monthly housing payment that makes your budget uncomfortable, that's not much of a victory.
Liquidity matters.
So does monthly cash flow.
The goal is to find the balance between the two.

Sometimes 20% Down Is Clearly the Right Decision
There are plenty of situations where I like 20% down.
Maybe you have significant liquidity even after closing.
Maybe eliminating PMI creates meaningful savings.
Maybe the lower loan amount gets your payment exactly where you want it.
Maybe you have no better use for the additional cash.
Maybe reducing debt is a major personal priority.
Maybe the financing improves materially at that loan-to-value.
Maybe you simply value having less debt and the numbers support it.
Great.
Put 20% down.
I'm not anti-down-payment.
I'm anti-doing-things-without-running-the-numbers.
Sometimes More Than 20% Makes Sense
The same logic applies in the other direction.
There are buyers who should consider putting 25%, 30%, or more down.
Maybe we're trying to hit a specific monthly payment.
Maybe reducing the loan amount improves the financing.
Maybe you're approaching retirement and prioritizing lower fixed expenses.
Maybe you have significant cash and want less leverage.
Maybe there's a specific qualification issue we're solving.
Twenty percent isn't a ceiling any more than it's a requirement.
It's just one point on the spectrum.
And Sometimes 5% or 10% Is the Better Strategy
Suppose you have enough cash to put 20% down, but doing so would use almost all of your liquid savings.
Maybe we compare 10% down instead.
Yes, the payment is higher.
Yes, there may be PMI.
But perhaps you keep another $40,000 or $50,000 available.
Now we ask:
What's the monthly cost of keeping that money?
How much PMI are we paying?
How much does the payment change?
How long might the PMI remain?
What could that cash do for you?
How important are reserves?
Once you know those answers, you can make an informed decision.
That's a much better process than:
"My parents told me I should put 20% down."
I love parents.
Parents are also not underwriting your mortgage.
Seller Concessions Can Affect the Decision Too
Let's say you planned to use $60,000 for your down payment and another $12,000 for closing costs.
Then your Realtor negotiates $10,000 in seller concessions.
Now we have choices.
Maybe those concessions cover most of your allowable closing costs and you keep the extra cash.
Maybe we use some toward the interest rate.
Maybe that changes how much you want to put down.
This is why the mortgage strategy should evolve with the transaction.
The plan we build before you find a house gives us a framework.
The actual property and negotiation give us the final pieces.

Your Down Payment Shouldn't Be Decided in Isolation
When I'm helping someone determine how much to put down, I want to understand more than what's in the savings account.
I want to know:
What monthly payment feels comfortable?
How much do you want left after closing?
Do you have an emergency fund?
Are you carrying other debt?
Are you investing?
Are there major expenses coming?
Do you expect your income to change?
How long do you expect to own the property?
Could this become a rental?
Are you planning another real estate purchase?
What matters more right now, lower monthly expenses or greater liquidity?
Those answers tell me much more than:
"I have $100,000 available."
Run Multiple Scenarios Before You Decide
This is one of the easiest ways to make a better decision.
Don't ask your lender for one option.
If you're considering 20% down, let's compare it with 15%.
And 10%.
Maybe 5% if it makes sense.
For each option, I want to see:
Cash to close.
Loan amount.
Interest rate and cost.
Mortgage insurance, if applicable.
Monthly payment.
Money remaining after closing.
Then we can actually see what each additional dollar of down payment is buying you.
Sometimes the winner becomes obvious.
Sometimes the differences are surprisingly small.
Either way, now we're making the decision with actual information.
Don't Drain Your Savings Just to Say You Avoided PMI
This is probably the biggest takeaway.
Avoiding mortgage insurance can be a good financial goal.
Having money is also a good financial goal.
If putting 20% down leaves you with healthy reserves and comfortably accomplishes what you want, fantastic.
If putting 20% down leaves you checking the couch cushions for your first mortgage payment, maybe we should reconsider.
Homeownership is a long-term financial decision.
Your ability to handle the unexpected matters.
I care a lot more about your overall financial position than whether we can proudly say there isn't a PMI line on your mortgage statement.
So, How Much Should You Put Down?
Enough to create the right balance between:
Your monthly payment.
Your cash to close.
Your mortgage insurance.
Your financing terms.
Your liquidity.
Your other financial goals.
And your comfort level.
For one buyer, that's 20%.
For another, it's 10%.
For another, it's 5%.
There is no medal at closing for putting the most money down.
The goal is to own the home with a mortgage structure that makes sense for the rest of your financial life.
That's the difference between mortgage shopping and mortgage planning.
If you're thinking about buying a home in Dallas-Fort Worth or anywhere in Texas, I'm happy to run the scenarios with you.
We'll compare different down payments, look at what each option does to your monthly payment and cash position, and figure out where your money is actually doing the most good.
Because the question isn't simply:
"How much can I put down?"
It's:
"How much should I put down?"
