How Much Should I Put Down on a House? 3%, 5%, 10% or 20% Compared

For many buyers, the best down payment is the amount that produces an affordable monthly payment while still leaving enough cash for closing costs, emergencies, repairs, moving expenses and other financial goals.

A larger down payment generally reduces the mortgage balance, monthly payment and total interest. On a conventional mortgage, reaching 20% down can also eliminate private mortgage insurance. But putting too much down can leave you with very little accessible cash after closing.

In most cases, mortgages are available with significantly less than 20% down. The Consumer Financial Protection Bureau says buyers generally need at least 3% of the target home price, although many loan types and lenders require 5% or more. The CFPB also notes that buyers can often save money by reaching 10% down and generally save the most by reaching 20%.

How much down payment do you actually need?

The minimum down payment depends on the mortgage program, lender, property, borrower and occupancy type.

• Conventional mortgages backed through certain Fannie Mae and Freddie Mac programs can allow down payments as low as 3%.
• FHA states that qualifying borrowers may make a down payment as low as 3.5% of the purchase price.
• The Department of Veterans Affairs does not require a down payment for an eligible VA-guaranteed purchase loan, although an individual lender may require one in certain cases.
• USDA's Single Family Housing Guaranteed Loan Program can provide 100% financing for qualifying borrowers purchasing eligible properties.

Is 20% down required to buy a house?

No. Twenty percent down is not required for many home purchases. The idea that every buyer must put 20% down usually comes from the mortgage-insurance threshold for conventional loans. When a conventional mortgage exceeds 80% of the home's value, the lender will commonly require private mortgage insurance.

That does not mean a lower down payment is necessarily a bad decision. Mortgage insurance can allow a buyer to purchase sooner, preserve an emergency fund, keep money available for repairs, avoid selling investments, retain cash for a renovation and maintain financial flexibility.

What changes when you put more money down?

1. Your mortgage balance is lower

Every additional dollar of down payment reduces the initial mortgage principal by one dollar.

2. Your monthly principal-and-interest payment falls

A smaller mortgage produces a lower required payment when the rate and term remain the same.

3. You pay less mortgage interest

Because interest is charged on the outstanding balance, reducing the initial principal lowers future interest costs.

4. Mortgage insurance may fall or disappear

With a conventional mortgage, mortgage-insurance pricing generally changes based on the loan-to-value ratio and borrower profile. Reaching 20% down commonly eliminates the initial PMI requirement.

5. Your interest rate may improve

A larger down payment can sometimes improve lender pricing because it reduces the loan-to-value ratio and lender risk. The CFPB notes that larger down payments can improve the likelihood of approval and may produce better loan terms, although the actual pricing depends on the complete loan profile.

6. You have less liquid cash

Money used for a down payment becomes home equity. It remains part of your net worth, but accessing it later may require selling the home, obtaining a HELOC, taking a home-equity loan or completing a cash-out refinance. Each option can involve qualification requirements, costs and market risk.

3% vs. 5% vs. 10% vs. 20% down payment example

Consider a $500,000 home financed with a hypothetical 30-year fixed mortgage at 6.50%. For illustration, assume conventional PMI equals 0.50% of the original mortgage balance annually for down payments below 20%.

What this example shows

Moving from 10% to 20% down requires an additional $50,000 at closing. Under these illustrative assumptions, it reduces the initial principal-and-interest-plus-PMI payment by approximately $504 per month.

However, the 10% down buyer retains $50,000 that could potentially be used for:

• Emergency reserves
• Home improvements
• Investment
• Paying off other debt
• Moving expenses
• Furniture or appliances
• Temporary income disruption

The best choice depends on what happens to the retained money and how long the mortgage remains in place.

Is 3% down a good idea?

A 3% down payment may be appropriate when buying sooner and preserving cash are more important than minimizing the mortgage payment.

Potential advantages

• Lowest initial down payment among common conventional options
• More cash remains available after closing
• May allow the buyer to purchase without waiting years to save 20%
• Can preserve emergency reserves
• Can keep money available for repairs and moving costs

Potential disadvantages

• Larger mortgage balance
• Higher monthly payment
• Likely mortgage insurance
• Less initial equity
• Greater sensitivity to a decline in home value
• Potentially different rate or fee pricing

A 3% down payment is not automatically irresponsible. It becomes risky when the buyer also has no meaningful cash reserves, a payment near the top of the household budget, uncertain income, significant immediate repair needs, or no room for taxes or insurance to rise. The down payment should be evaluated together with the entire post-closing financial position.

Is 5% down a good idea?

Five percent down can provide a middle ground between minimum-down-payment financing and tying up a large amount of cash. Compared with 3% down, 5% down reduces the mortgage balance, may improve pricing, lowers the payment, and still preserves substantially more cash than 20% down. However, conventional PMI will generally still apply.

Five percent down may be worth comparing when you want to preserve reserves, you have substantial post-closing expenses, you expect income growth, your payment remains comfortable, or waiting to save 20% would substantially delay the purchase.

Is 10% down a good idea?

Ten percent down is often a valuable comparison point because it cuts the gap between minimum down and 20% down in half. The CFPB notes that borrowers can often save money when they reach at least 10% down.

• A meaningfully smaller mortgage than 3% or 5% down
• Lower mortgage-insurance cost than a smaller down payment in many scenarios
• A lower monthly payment
• More initial equity
• More retained cash than 20% down

Ten percent down may provide a useful balance for buyers who could technically reach 20% but would be left with inadequate reserves. It is not universally optimal — the actual result depends on PMI cost, mortgage rate, credit profile, expected holding period, use of retained cash, investment return, other debts and your need for liquidity.

Is 15% down worth it?

Fifteen percent down reduces the mortgage further while requiring $25,000 less cash than 20% down on a $500,000 home. It may be attractive when you want a lower payment but cannot comfortably reach 20%, the PMI quote is relatively inexpensive, you need to retain some cash, or the additional 5% needed to reach 20% has a more valuable use elsewhere.

Should you put 20% down?

Twenty percent down can be an excellent choice when it does not compromise your reserves or other financial priorities.

Potential advantages

• No initial conventional PMI
• Lower required payment
• Lower starting mortgage balance
• Less interest paid
• More initial equity
• Reduced risk of owing more than the property is worth
• Potentially better mortgage pricing

Potential disadvantages

• Much more cash required at closing
• Less money available for emergencies
• Less liquidity for repairs and improvements
• Opportunity cost if the money could produce greater value elsewhere
• More of your net worth concentrated in one property

The CFPB advises buyers to consider that money placed into the home is not readily available for emergency expenses or other savings goals.

Twenty percent down may be appropriate when

• You can still maintain your required cash reserve.
• The lower payment materially improves your budget.
• PMI is expensive.
• You prefer a guaranteed reduction in debt over investment risk.
• You expect to retain the mortgage for a long time.
• You do not have higher-cost debt that should be addressed first.
• The additional down payment does not interfere with necessary repairs or planned expenses.

Twenty percent down may be too much when

• It would use nearly all your savings.
• You would need to use credit cards for moving or repairs.
• You expect major improvements immediately after closing.
• Your income is variable.
• You need cash for a business or other major obligation.
• You would sell investments with substantial tax consequences.
• A smaller down payment still produces a comfortable payment.

Should you put more down or keep the cash?

This is the most important down-payment optimization question. Putting more money down produces a largely predictable benefit: a lower mortgage balance, lower required payment, lower interest, potentially lower PMI and potentially better loan pricing.

Keeping the cash produces flexibility but comes with uncertainty. The retained cash could earn interest, be invested, cover the larger payment, fund home expenses or remain as an emergency reserve.

The correct comparison

Do not simply compare the mortgage rate against an expected investment return. A smaller down payment may create a higher mortgage payment, PMI, a higher mortgage rate, more interest and a larger remaining balance. If the retained investment account is used each month to cover that higher payment, its balance will grow more slowly and may eventually be depleted.

The true investment breakeven is the return at which both down-payment strategies produce the same ending financial position.

How much cash should you keep after closing?

Your down payment is only one part of the cash required to purchase a home. The CFPB explains that estimated cash to close can include the down payment and closing costs, reduced by deposits, seller credits and other adjustments.

• Down payment
• Lender and title charges
• Prepaid interest
• Initial homeowners-insurance premium
• Initial escrow deposits
• Inspection
• Moving costs
• Repairs, appliances and furniture
• Utility deposits
• Emergency savings

On a $500,000 home, $70,000 equals 14% down. A 20% down payment would require $100,000 and would violate the buyer's selected reserve and expense targets. Even though 20% lowers the mortgage payment, it may not be the most responsible cash allocation in this example.

Does a larger down payment eliminate PMI?

On many conventional mortgages, putting 20% down prevents PMI from being required at closing. Putting less than 20% down does not necessarily mean PMI will remain for the entire mortgage.

For many covered conventional loans, a borrower may request PMI cancellation when the balance reaches 80% of the home's original value, subject to legal and servicer requirements. PMI generally must terminate automatically when the balance is scheduled to reach 78% of the original value if the borrower is current.

• Payment history
• Property value
• Loan type
• Additional liens
• Servicer requirements
• Whether the mortgage is considered high risk

FHA vs. conventional: does the down payment change which is better?

Yes. FHA and conventional mortgages can produce different results at the same down payment because they may have different interest rates, upfront mortgage insurance, monthly mortgage insurance, credit pricing, loan limits, cancellation rules and closing costs.

The CFPB states that FHA loans can be competitive for borrowers with smaller down payments or lower credit scores. For borrowers with stronger credit and a medium down payment of roughly 10% to 15%, FHA financing can be more expensive than conventional financing.

So do not decide that FHA is better because the rate is lower. Compare cash to close, financed upfront mortgage insurance, monthly mortgage insurance, the full payment, five-year cost, remaining balance, expected refinance and mortgage-insurance duration.

Should you wait until you have 20% down?

Not necessarily. Waiting may be beneficial if it allows you to reduce the mortgage payment, avoid PMI, improve credit, reduce debt, build reserves or qualify for better pricing. But waiting also has costs and risks: additional rent, future home-price changes, future mortgage-rate changes, delayed equity accumulation, changes in available inventory and changes in personal circumstances.

Should you pay off debt or increase the down payment?

Paying off debt can sometimes improve affordability more than increasing the down payment. Suppose you can use $15,000 in one of two ways.

Option A: add $15,000 to the down payment

• Mortgage is $15,000 smaller
• Mortgage payment falls
• Interest is reduced

Option B: pay off a $15,000 auto loan

• Entire auto payment may disappear
• Debt-to-income ratio falls
• Monthly cash flow improves

If the auto payment is $600 per month, eliminating it may improve monthly affordability more than applying $15,000 to a 30-year mortgage. However, paying off debt also leaves less cash for closing. Compare the monthly payment eliminated, cash used, new mortgage payment, new debt-to-income ratio, cash remaining and maximum comfortable home price.

Five questions to decide how much to put down

1. What is my cash to close?

• Down payment
• Closing costs
• Points
• Prepaids
• Escrow funding
• Less deposits and credits

2. How much must remain after closing?

Set a specific reserve target before selecting the down payment.

3. What does each down payment do to my payment?

Compare 3%, 5%, 10%, 15% and 20%, using actual lender quotes whenever possible.

4. What does mortgage insurance cost?

Request the PMI or MIP amount for every scenario. Do not rely only on a generic percentage.

5. What would I do with the cash I retain?

Be realistic: keep it in savings, invest it, pay other debt, renovate the home, cover the higher payment — or spend it. Retaining $50,000 only creates financial value if the money remains available or is used productively.

A practical down-payment decision framework

1. Establish the minimum viable down payment. Identify which mortgage programs you could use and the minimum required amount.
2. Protect closing costs and reserves. Do not allocate every available dollar to the down payment.
3. Obtain quotes at several down payments. Ask the lender for comparable Loan Estimates at 5%, 10%, 15% and 20%, including rate, APR, points, lender credits, PMI, principal and interest, and cash to close.
4. Identify threshold benefits. Determine whether moving to another tier provides a lower rate, lower PMI, no PMI, lower fees or better qualification.
5. Compare the retained-cash alternative. Model what happens to the money not used for the down payment.
6. Test your expected holding period. A benefit that takes 12 years to recover may not matter if you expect to sell or refinance after five years.
7. Select the best balanced option. The highest projected net worth may not be the best choice if it creates an uncomfortable payment or inadequate reserves.

Which down payment is best for each goal?

Calculate your best down payment

The Down Payment Optimizer takes your home price, available cash, minimum reserve, planned post-closing expenses, mortgage rate at each down payment, PMI or MIP, closing costs, expected holding period, investment return and the treatment of monthly payment differences.

It returns a comfort-based down payment, the lowest-payment option, the highest-liquidity option, the highest projected financial-position option, cash to close, cash remaining, monthly payment, mortgage-insurance cost, remaining mortgage balances, the investment breakeven return, a cash-depletion date, and results after 3, 5, 10 and 15 years.

The bottom line

The best down payment is not necessarily the largest down payment you can technically make. A good down payment should produce a monthly payment you can comfortably manage, preserve adequate cash after closing, account for repairs and planned expenses, consider PMI and mortgage pricing, support your long-term financial goals, avoid depending on uncertain future refinancing, and reflect what will actually happen to any retained cash.

Twenty percent down may produce the lowest payment and borrowing cost. A smaller down payment may produce better liquidity or even a higher projected net worth when retained cash is used productively. The correct answer requires comparing the complete financial position — payment, cash, equity, mortgage insurance, investment opportunity cost and long-term value.
