How Much Do You ACTUALLY Need to Buy a House?

The Money You ACTUALLY Need to Buy a House

Jenny Jones, The Jones Team at Baird & Warner  |  9 min read  |  Last reviewed: September 2026

There’s a number floating around in the head of almost every future home buyer.

It’s usually large.

It’s usually intimidating.

And it’s usually based on some combination of things they heard from their parents, TikTok, a coworker who bought a house in 2017, and that one friend who suddenly became a mortgage expert after closing on exactly one property.

It’s the giant mystery pile of money you supposedly need before you’re even allowed to think about buying a house.

Here’s the problem:

That pile isn’t really a thing.

The money involved in buying a home doesn’t all do the same job.

Some may become your down payment. Some handles the costs of actually buying the property. Some gets you through inspections, moving and those first few weeks of homeownership. And ideally, some stays exactly where it is—in your bank account.

So instead of asking:

“How much money do I need to buy a house?”

Let’s ask a much better question:

“What does my money need to DO?”

Because once you understand that, saving for a future home starts feeling a whole lot less mysterious.

Bucket #1: Your Down Payment

We already tackled the giant “YOU NEED 20% DOWN” myth in our article WAIT. WHO TOLD YOU THAT YOU NEED 20% DOWN?.

The refresher version?

Twenty percent is not a universal requirement.

Different mortgage programs have different minimum down-payment requirements, and some qualified buyers may be eligible for options requiring considerably less than 20%.

For example, FHA-insured financing can allow a minimum required investment of 3.5% for eligible borrowers. Other conventional and government-backed programs have their own requirements and eligibility rules.

Putting more money down can have advantages, but “I don’t have 20%” does not automatically mean “I can’t buy a house.”

That’s why your down payment is only one part of your savings plan.

Not the whole enchilada.

Bucket #2: Your Buying & Closing Costs

This is the bucket future buyers sometimes forget exists.

Your down payment goes toward the purchase price of the home.

Closing costs are different.

These are costs associated with obtaining the mortgage and completing the transaction. Depending on your situation, they can include expenses such as:

For general planning purposes, the Consumer Financial Protection Bureau and Freddie Mac tell buyers to anticipate closing costs that can often fall somewhere around 2% to 5% of the purchase price, separate from the down payment.

But—and this is a very important but—

That is a planning range. It is NOT a quote.

Actual closing costs can vary significantly depending on the property, location, lender, loan program, timing and transaction.

So please don’t whip out the calculator, multiply a random house price by 3%, write it in permanent marker and declare the case closed.

We’re planning here, not tattooing numbers onto anybody.

Wait...Do I Personally Have to Pay Every Closing Cost?

Not necessarily.

Depending on the loan program and transaction, there may be opportunities for things such as seller credits or lender credits to help offset certain closing costs.

That’s useful.

It is not magic.

Seller credits have to be negotiated and may be subject to loan-program limitations. A lender credit can also involve a financial tradeoff—such as accepting a higher interest rate in exchange for reducing certain upfront costs.

So yes, credits can absolutely be part of a home-buying strategy.

But I wouldn’t build your entire Future Home Plan around:

“Eh, somebody else will probably pay it.”

That’s not a plan.

That’s optimism wearing a fake mustache.

Bucket #3: The Stuff Between “Offer Accepted” and “Where Did We Pack the Coffee Maker?”

Not every expense surrounding a home purchase appears neatly under the heading Mortgage Costs.

Real life insists on participating too.

Depending on your purchase, you may want to plan for things like:

• ◆a general home inspection
• ◆specialized inspections when appropriate
• ◆moving expenses
• ◆utility or service setup expenses
• ◆immediate household purchases
• ◆repairs or projects you choose to handle after closing

These aren’t all mandatory mortgage expenses, and every buyer’s situation will be different.

But they’re worth thinking about before you spend every available dollar getting the keys.

Because houses have an uncanny ability to convince perfectly rational adults that they urgently need seventeen things from Home Depot within 48 hours of closing.

You went in for a screwdriver.

You left with a ladder, six lightbulbs, two plants, a shop vac and a receipt for $287.

Welcome to homeownership.

Bucket #4: The Money You DON’T Spend

This one isn’t nearly as exciting as the down payment.

It’s also incredibly important.

Ideally, buying your home doesn’t require draining every account you own.

There is a difference between:

“Can I technically get myself to the closing table?”

and

“Can I comfortably become a homeowner?”

When you’re figuring out how much of your savings could eventually go toward buying, you also want to consider what you’ll need after closing.

That can include your normal monthly expenses, unexpected repairs, maintenance and good old-fashioned life happening at inconvenient times.

The Consumer Financial Protection Bureau encourages prospective buyers to consider an emergency cushion when deciding how much cash they can comfortably put toward a home purchase, commonly referencing three to six months of expenses as a general emergency-savings guideline.

That doesn’t mean every future buyer must have exactly six months sitting untouched before they’re “allowed” to buy.

Your financial situation is yours.

The point is simpler:

Don’t automatically assume every dollar you’ve saved belongs to the house.

Some money may have another very important job:

keeping Future You comfortable after you get the keys.

So...What the Heck Is “Cash to Close”?

You’ll eventually hear this phrase during the mortgage process.

And no, it does not mean your lender expects you to arrive at closing with a duffel bag full of twenties.

Cash to Close is the amount you’ll ultimately need to bring to closing after the applicable pieces of your transaction are calculated.

That can include your down payment and closing costs, while also accounting for things such as deposits you’ve already made, seller credits and other adjustments.

Your Loan Estimate will include an Estimated Cash to Close, and later in the transaction your final numbers will be reflected in your Closing Disclosure.

The important lesson right now is:

You don’t need to memorize the mortgage paperwork yet.

Just knowing that distinction puts you ahead of where a lot of first-time buyers start.

So How Much Money Do YOU Actually Need?

Here’s the annoying-but-accurate REALTOR answer:

It depends.

I know.

Very satisfying.

But there’s a reason nobody can responsibly give every future buyer one magic savings number.

Imagine two people each have $15,000 saved.

So instead of staring at your current savings balance and asking:

“Is this enough?”

start asking:

What jobs would this money eventually need to do?

That’s a question you can actually build a plan around.

Where Future Buyers Get Tripped Up

What This Doesn’t Mean

Understanding these four buckets does not mean:

Home-buying readiness is more nuanced than that.

Right now, we’re doing something much simpler.

We’re turning a vague someday-goal into something you can actually start planning for.

Future Homeowner First. Home Buyer Later.

You don’t need to know your exact purchase price today.

You don’t need to know exactly when you’ll move.

And you certainly don’t need to start touring houses because you opened a savings account on Tuesday.

Right now, your job is simply to start preparing.

Once your savings grows and your timeline becomes clearer, then we can start putting real numbers behind your plan.

Because becoming a prepared homeowner doesn’t begin when somebody hands you a preapproval letter.

It begins much earlier.

Usually with a few small, boring, ridiculously unglamorous decisions that Future You will be very glad you made.

You don’t need one giant mystery pile of money.

Your money just needs jobs.

And now you know what some of those jobs are.
