Saving for a house is not as simple as taking the price of a home and multiplying it by 20%.
You may be able to buy with far less than 20% down, depending on the mortgage program you qualify for. At the same time, the down payment is only one part of the cash you may need. Closing costs, inspections or other pre-closing expenses, moving costs, and the cash you want left after closing all belong in the plan.
A better way to approach the goal is to estimate your total house cash target, subtract what you have already saved, and then determine what monthly contribution your timeline and budget can realistically support.
Key takeaways
- You do not automatically need a 20% down payment. Some mortgage programs allow much smaller down payments, subject to eligibility and underwriting requirements.
- Your savings target should include more than the down payment. Estimate closing costs, other purchase expenses, and the amount of accessible cash you want to retain after closing.
- Putting less down can reduce the cash required upfront, but it generally increases the mortgage balance and may add mortgage insurance or other program costs.
- The right place for your house savings depends less on an arbitrary number of years and more on how soon you may need the money and how much investment loss your purchase timeline could tolerate.
- Avoid building the plan around predictions that home prices, mortgage rates, or investment markets will move in your favor.
How much do you actually need to save for a house?
Start with the price range you are realistically considering in the market where you want to buy.
National median home prices can provide context, but they are not especially useful for setting your personal savings target. Prices can vary enormously between states, cities, neighborhoods, and property types.
Your starting formula is closer to:
Down payment + estimated closing and purchase costs + desired post-closing cash – current house savings = remaining savings target
Each part deserves its own estimate.
1. Your down payment
Twenty percent is one possible down payment, not a universal requirement.
A larger down payment generally means borrowing less. It can also reduce the monthly mortgage payment and, on some conventional loans, eliminate the need for private mortgage insurance.
The tradeoff is that more of your cash becomes tied up in the home.
A smaller down payment requires less cash upfront and may allow you to purchase sooner, but you borrow more and may face additional mortgage-insurance or program costs.
Neither option is automatically better.
Do you actually need 20% down?
Different mortgage programs have different requirements.
| Loan type | Low-down-payment possibility | Important considerations |
|---|---|---|
| Conventional | Some programs permit down payments as low as 3% | Eligibility and mortgage-insurance requirements vary |
| FHA | Financing can be available with as little as 3.5% down for borrowers meeting applicable requirements | FHA mortgage insurance applies |
| VA | Eligible borrowers may be able to purchase with no VA-required down payment | A VA funding fee may apply unless the borrower is exempt |
| USDA | Eligible borrowers and properties may qualify for 100% financing | Geographic, household-income, and program requirements apply |
These are program possibilities, not guarantees that a particular borrower will qualify for the lowest available down payment.
Lenders also apply underwriting requirements involving income, debts, credit, assets, property details, and other factors.
Conventional PMI is different from FHA mortgage insurance
This distinction is easy to miss.
Private mortgage insurance, or PMI, is commonly associated with certain conventional mortgages where the borrower puts less than 20% down.
FHA mortgage insurance, or MIP, follows separate FHA rules.
VA and USDA loans have their own fee structures as well.
So “less than 20% down means PMI” is too broad.
If you are comparing different down payments, use the actual mortgage-insurance or program-fee quote for the loan you are considering instead of estimating it from a generic national percentage.
PMI does not simply disappear at 20% equity
For many borrower-paid conventional mortgages covered by federal PMI cancellation rules, you may generally be able to request cancellation when the principal balance is scheduled to reach 80% of the home’s original value, subject to applicable requirements.
Automatic termination generally occurs when the scheduled balance reaches 78% of the home’s original value and applicable conditions are met.
The Consumer Financial Protection Bureau’s PMI guidance explains the distinction.
These rules should not be confused with FHA mortgage-insurance rules.
Smaller vs. larger down payment: what changes?
Instead of assuming that waiting for 20% or buying with 5% is always better, compare what each choice changes.
| Smaller down payment | Larger down payment |
|---|---|
| Less cash required upfront | More cash required upfront |
| Larger mortgage balance | Smaller mortgage balance |
| May involve mortgage insurance or additional program costs | May reduce or eliminate some mortgage-insurance costs |
| Leaves more cash outside the home | Puts more of your cash into home equity |
| May shorten the saving period | May require more time to save |
Do not make this comparison using an assumed future home-price appreciation rate.
Home prices can rise, fall, or stay relatively flat, and local markets can behave very differently from national averages.
Compare the choices using the home price, mortgage quotes, insurance costs, and cash reserves available to you now.
The down payment is not the same as cash to close
The down payment is only one piece of the purchase.
The Consumer Financial Protection Bureau notes that closing costs typically run about 2% to 5% of the purchase price, although actual costs depend on the property, lender, loan, location, and transaction.
Closing-related costs can include items such as lender charges, appraisal and title-related costs, prepaid taxes or insurance, and other transaction expenses.
You may also have costs that occur before or around closing, such as an inspection, moving expenses, or immediate work on the home.
Do not double-count earnest money
You may pay some cash before the closing date.
For example, an earnest money deposit may be paid after your purchase contract is signed. If the transaction closes, that deposit may later be credited toward amounts you owe at closing.
That means an earnest money deposit should not simply be added on top of your estimated cash-to-close target a second time.
The CFPB’s Loan Estimate guidance shows how deposits already paid, seller credits, down payment, and closing costs can affect Estimated Cash to Close.
Once you are under contract, your actual Loan Estimate and later Closing Disclosure are much more useful than a generic percentage estimate.
Build your house cash target
Suppose you are considering a $350,000 home and planning a 5% down payment.
The arithmetic for the down payment is straightforward:
- Home price: $350,000
- Down payment at 5%: $17,500
If you use 3% of the purchase price as an illustrative closing-cost estimate:
- Estimated closing costs: $10,500
That gives you an illustrative target of:
$28,000 before other purchase expenses and the cash you want left after closing.
The important phrase is before your post-closing reserve.
Do not interpret $28,000 as “I am financially ready to buy this house.” Your actual mortgage quote, closing costs, moving needs, property condition, and desired remaining cash can all change the number.
Another example
For a $400,000 home with 10% down:
- Down payment: $40,000
- Illustrative closing costs at 3%: $12,000
- Cash target before other expenses and reserves: $52,000
With 20% down:
- Down payment: $80,000
- Illustrative closing costs at 3%: $12,000
- Cash target before other expenses and reserves: $92,000
These examples show how to build the calculation. They are not recommended down-payment amounts or estimates of what your specific purchase will cost.
Do not forget the cash you want left after closing
Buying a house with almost nothing left in cash can create a second problem immediately after solving the first one.
Homeowners can face insurance deductibles, repairs, appliance failures, moving costs, and income interruptions.
There is no single reserve amount that works for every buyer.
Consider factors such as:
- How stable your household income is
- Whether one or multiple incomes support the household
- Existing debt and recurring obligations
- Insurance deductibles
- The age and condition of the property
- Major repairs you already expect
- How quickly you could rebuild savings after closing
Treat the amount you want left after closing as part of your house savings target rather than whatever happens to remain.
How long will it take to save?
Once you know the approximate target, the basic math is simple.
Here is what different monthly savings amounts add up to before interest:
| Monthly savings | 2 years | 3 years | 4 years | 5 years |
|---|---|---|---|---|
| $500 | $12,000 | $18,000 | $24,000 | $30,000 |
| $800 | $19,200 | $28,800 | $38,400 | $48,000 |
| $1,000 | $24,000 | $36,000 | $48,000 | $60,000 |
| $1,500 | $36,000 | $54,000 | $72,000 | $90,000 |
| $2,000 | $48,000 | $72,000 | $96,000 | $120,000 |
These figures show contributions only. Interest earned will depend on the account, its rate, and when deposits are made.
A simple version of your own calculation is:
Remaining savings target ÷ number of months until your target purchase = approximate monthly contribution needed
For example, if your remaining target is $36,000 and you want to reach it in 36 months:
$36,000 ÷ 36 = $1,000 per month
That is deterministic arithmetic. Whether $1,000 per month is sustainable is a separate question.
What if the required monthly savings is too high?
Suppose your plan says you need to save $1,200 per month, but your budget can sustainably support only $750.
You have a $450 monthly gap.
There are only a few fundamental ways to close it:
- Increase the amount of monthly cash available for the goal
- Reduce the cash target, if doing so still leaves you with a suitable purchase plan
- Extend the timeline
This framework is more useful than assuming everyone can solve a down payment by cutting coffee, getting a roommate, or starting a side hustle.
Look first at the biggest parts of your cash flow.
A meaningful reduction in a major recurring expense can have more impact than trimming small discretionary purchases. Raises, bonuses, or other windfalls can also shorten the timeline if you decide that directing part of them to the house fund fits your other priorities.
Additional income can help too, but count the after-tax cash you actually expect to retain, not a headline side-hustle revenue number.
Automation can make a savings plan easier to follow, but it cannot create a positive monthly margin. If an automatic transfer forces you to borrow later in the month, the contribution is not sustainable.
Where should you keep down-payment savings?
The most important question is not simply whether your purchase is two, three, or five years away.
Ask:
What happens to my home purchase if this money loses substantial value right before I need it?
If your planned purchase date is relatively firm and a market decline would force you to delay the purchase, taking substantial stock-market risk with the core down-payment fund may be a poor fit.
Options focused on preserving cash may include savings accounts at FDIC-insured banks and other appropriate cash or short-term savings products.
A separate account or savings bucket can also make the house goal easier to track.
If your purchase date is much more flexible, you may have a greater ability to tolerate fluctuations, but that does not automatically mean house money should be invested aggressively.
Match the risk to the goal.
Should you reduce retirement contributions to save for a house?
Saving for a home and saving for retirement are two different goals competing for the same cash flow.
There is no universal rule that says:
always keep retirement contributions at a specific level,
or:
pause your Roth IRA for two years and then restart it.
Before redirecting retirement savings toward a home, consider:
- How much you are currently contributing to retirement
- Whether your workplace plan offers employer matching contributions and how vesting works
- How your retirement savings compare with your long-term goal
- Whether you carry expensive debt
- How much cash the home purchase actually requires
- How flexible your purchase timeline is
- How much changing retirement contributions would actually shorten the house timeline
If contributing enough for a workplace match fits your cash flow, the employer contribution can materially increase the amount going toward retirement.
But employer matching is a plan contribution, not a guaranteed investment return, and generic advice should not require you to miss essential bills or create expensive debt simply to follow a rule of thumb.
If you temporarily change retirement contributions for the home goal, decide how and when you will review that decision instead of assuming the lower contribution will automatically reverse itself after closing.
Low-down-payment and homebuyer assistance options
Your own savings may not be the only source of purchase cash.
Some buyers may qualify for:
- Low-down-payment conventional programs
- FHA, VA, or USDA financing
- State or local down-payment assistance
- Closing-cost assistance
- Grants
- Forgivable or deferred loans
- Other housing-agency programs
Eligibility and terms vary widely.
Some assistance is a grant. Some must eventually be repaid. Some assistance comes as a second mortgage or has occupancy, income, property, or resale conditions.
Focus on the terms, not just the headline amount.
A HUD-approved housing counselor can help identify programs that may apply in your area.
Make sure the target home price fits your monthly budget
Saving enough cash to close does not necessarily mean the home is affordable after closing.
There are two different questions:
- What mortgage might a lender approve?
- What housing payment fits comfortably into your own budget?
They are not the same.
Instead of relying on a universal 28/36 rule or converting salary directly into a home-price maximum, estimate the actual all-in monthly cost.
That can include:
- Mortgage principal and interest
- Property taxes
- Homeowners insurance
- Mortgage insurance, if applicable
- HOA dues, if applicable
- Other recurring housing costs
- A realistic allowance for maintenance and repairs
Then compare that amount with your actual monthly cash flow and existing obligations.
If you need a deeper affordability calculation, use our How much house can I afford? guide rather than treating a lender’s maximum approval as your target purchase price.
How mortgage rates change the monthly payment
The mortgage rate can materially change the payment even when the loan amount stays the same.
Here is a hypothetical $315,000 30-year fixed-rate loan, assuming a fully amortizing loan and no extra principal payments:
| Interest rate | Approx. monthly principal and interest |
|---|---|
| 5.0% | $1,691 |
| 6.0% | $1,889 |
| 6.5% | $1,991 |
| 7.0% | $2,096 |
| 7.5% | $2,203 |
These figures include principal and interest only. They do not include property taxes, homeowners insurance, mortgage insurance, HOA dues, or other housing costs.
The point is not to predict which mortgage rate you will receive.
It is to understand that a target home price that works under one rate may produce a meaningfully different monthly payment under another.
When you are closer to buying, compare actual Loan Estimates from multiple lenders rather than building your plan around an assumed future rate.
A purchase should work under the financing terms available when you buy. Treat a possible future refinance as an option, not part of the affordability calculation.
What about your credit?
Credit can affect mortgage eligibility and pricing, but there is no single credit score that guarantees mortgage approval or the best interest rate.
Requirements can differ by:
- Mortgage program
- Lender
- Down payment
- Loan-to-value ratio
- Other parts of the application
Review your credit reports early enough to dispute genuine errors and understand what lenders are likely to see.
When you begin mortgage shopping, compare actual offers rather than assuming that reaching one specific score automatically unlocks the best rate.
Can you use retirement money for a down payment?
Tax rules may allow access to retirement money for a home purchase in some circumstances.
That does not automatically make retirement accounts good home-savings accounts.
IRA first-time-homebuyer exception
Federal tax rules provide a first-time-homebuyer exception to the 10% additional tax for up to $10,000 of qualifying IRA distributions over your lifetime.
The exception is to the additional tax. It does not automatically make every dollar of the distribution income-tax-free.
Traditional and Roth IRA distributions also have different tax rules, and specific definitions, qualified acquisition-cost rules, and timing requirements apply to the first-time-homebuyer exception.
Review the IRS rules for exceptions to the additional tax on early retirement distributions and IRS Publication 590-B before including IRA money in a home-purchase plan.
401(k) loans
Some workplace plans allow participant loans, but plans are not required to offer them.
Federal rules generally limit how much can be borrowed, and your plan can impose additional requirements. Loans used to purchase a principal residence can also have different repayment-term rules from ordinary plan loans.
A loan that complies with the applicable requirements generally is not treated as a taxable distribution when made, but it still creates repayment obligations and can create complications if your employment changes.
Review the IRS guidance on retirement-plan loans and your own plan before using a 401(k) as part of the purchase.
The important distinction is:
Access to retirement money and whether using it makes sense for your plan are two different questions.
Frequently asked questions
Do I need 20% down to buy a house?
No.
Some conventional programs permit smaller down payments, while FHA, VA, and USDA programs can provide other low- or no-down-payment possibilities for eligible borrowers.
A smaller down payment can increase the mortgage balance and may introduce mortgage insurance or other program costs, so compare the full loan rather than down payment alone.
How much should I save besides the down payment?
Include estimated closing costs, transaction-specific pre-closing expenses, moving or immediate-home costs that apply to you, and the amount of accessible cash you want left after closing.
Remember that deposits already paid, such as earnest money that will be credited at closing, should not be counted twice.
The final number depends on the home and loan.
Should I invest my down-payment money?
It depends primarily on how soon you may need the money and how flexible the purchase date is.
If a significant market decline would force you to postpone a near-term purchase, volatile investments may not fit the goal.
Should I wait for mortgage rates or home prices to fall?
Short-term mortgage rates and local home prices cannot be predicted with enough reliability to make them the foundation of your purchase plan.
Build the purchase around the home price and financing terms you can actually obtain rather than requiring a future decline to make the numbers work.
How much cash should I have left after buying?
There is no universal number.
Choose a reserve based on your income stability, household obligations, insurance deductibles, property condition, expected repairs, and how quickly you could rebuild cash after closing.
The goal is to avoid a purchase that leaves routine surprises immediately dependent on new debt.
Bottom line
Start with a realistic home-price range in the market where you actually want to buy.
Estimate the down payment for the mortgage options you may qualify for, add estimated closing and other purchase costs, and decide how much accessible cash you want left after closing. Account for deposits you have already paid so the same money is not counted twice.
Then subtract what you have already saved.
What remains is your house savings gap.
Divide that gap across a timeline your cash flow can realistically support. If the monthly amount is too high, you can increase the monthly surplus, adjust the cash target, extend the timeline, or combine those approaches.
And for money you expect to need relatively soon, choose a level of risk that will not derail the purchase simply because financial markets fall at the wrong time.
The goal is not to predict the housing market perfectly or hit an arbitrary 20% down payment.
It is to reach closing with a purchase you can afford and enough cash left that owning the home does not immediately create the next financial emergency.
