The 20% myth has kept more people out of homes than almost any other piece of conventional wisdom in personal finance. Here's what different down payment amounts actually cost — and how to choose the right one for your situation.
The 20% down payment myth has kept more people out of homes than almost any other piece of conventional wisdom in personal finance. It gets repeated so often that a lot of buyers assume it's a legal requirement. It isn't. It never was.
The 20% figure exists for a specific reason: put down less than that on a conventional loan and you'll owe private mortgage insurance until your equity catches up. That's a real cost worth understanding — but it's a cost to be calculated and weighed, not a wall that stops you from buying until you've assembled a down payment that, in many markets, would take a decade or more to save.
The Minimum Down Payment by Loan Type
The floor for how little you can put down depends entirely on which loan program you use.
Conventional
3% min
HomeReady/Home Possible for first-time buyers. Standard repeat buyers need 5%. Below 20% triggers PMI until 80% LTV.
FHA Loan
3.5% min
Requires 580+ credit score. Score 500–579 needs 10% down. MIP stays for life of loan if under 10% down.
VA Loan
0% down
Eligible veterans, active-duty, and surviving spouses. No PMI ever. VA funding fee (1.25%–3.3%) can be rolled into loan.
USDA Loan
0% down
Qualifying rural/suburban areas only. Income limits apply. Guarantee fee can be financed. Property must be USDA-eligible.
The practical takeaway
Most buyers can get into a home with 3%–3.5% down. Veterans and qualifying rural buyers can buy with nothing down. The 20% benchmark is a threshold that eliminates PMI — not a requirement to purchase.
What Different Down Payment Amounts Actually Cost You
Down payment size affects four outcomes simultaneously: your loan amount, monthly payment, whether you owe PMI, and total interest paid. Based on a $325,000 home, 30-year fixed at 7%:

The monthly payment difference between 3% and 10% down is about $215 — meaningful, but not insurmountable. PMI at 3% down adds ~$210/month, but it's not permanent — it drops once you reach 80% LTV. The total interest difference between 3% and 20% down is roughly $77,000 over 30 years, but assumes you held the loan for the full term without refinancing or selling.

The Opportunity Cost Argument
Here's the question most down payment conversations skip: what's the alternative use for that money? Saving from 5% to 20% down on a $325,000 home means accumulating an additional $48,750. In the years it takes to save that difference, that capital could alternatively be invested in a diversified portfolio, used to eliminate high-interest debt, or kept as a liquid emergency reserve.
A buyer who puts 20% down has $65,000 locked in an asset they can't easily access without selling or refinancing. A buyer who puts 5% down and keeps $48,750 in liquid savings has flexibility, reserves, and exposure to different asset growth — along with a PMI payment that disappears once equity reaches 20%. Neither path is objectively superior. Both deserve to be modelled before committing.
The Liquid Cash Problem Most Buyers Don't See Coming
A common mistake among first-time buyers: saving aggressively for a large down payment, then arriving at closing with almost nothing left. Buying a home requires more liquid capital than just the down payment:
Closing costs — typically 2%–5% of the loan amount, due at closing
Moving expenses — often $1,000–$5,000 depending on distance and volume
Immediate home expenses — appliances, repairs, furniture, things every new homeowner discovers they need in the first 60 days
Emergency reserve — ideally 3–6 months of housing costs, liquid, after closing
⚠️ The liquidity trap
A buyer who scrapes together exactly 20% and arrives at closing drained may be financially more vulnerable than a buyer who put 10% down and kept $30,000 in liquid reserves. The PMI on the second buyer's loan costs money monthly. The lack of reserves on the first buyer's loan could cost everything if a job loss or major repair hits in month three.
Down Payment Assistance: The Resource Most Buyers Don't Know About
Roughly 2,000 down payment assistance (DPA) programs exist across the United States — offered by state housing finance agencies, local governments, nonprofits, and employers. Most first-time buyers have no idea they exist.
🎁
Grants
Money that never needs to be repaid, provided you meet eligibility requirements and often stay for a minimum period.
✂️
Forgivable Loans
A second loan forgiven incrementally over 5–10 years as long as you remain in the home. Effectively free if you stay.
⏳
Deferred Loans
No monthly payments. Due only when you sell, refinance, or pay off the first mortgage. No drag on your monthly budget.
Where to find assistance programs
Start with your state's housing finance agency — every state has one, and most maintain searchable databases of available assistance. The HUD website also maintains a directory of approved housing counseling agencies that can walk you through local options at no cost. If you've been waiting to save a larger down payment, it's worth spending two hours researching whether assistance could accelerate your timeline.
Does a Larger Down Payment Get You a Better Rate?
Generally, yes — though the relationship isn't as dramatic as many buyers expect. The rate improvement from increasing down payment from 5% to 20% on a conventional loan is typically 0.125% to 0.5% depending on lender, credit score, and market conditions. At $300,000 borrowed, a 0.25% improvement saves about $50/month.
Credit score has a far larger impact on your offered rate than down payment size. Improving a 680 credit score to 740 before applying will typically produce a more significant rate improvement than increasing down payment from 10% to 20%.
A Real Buyer Scenario: Running Both Paths
Taylor is buying a $295,000 home and has $45,000 saved. She's weighing two approaches:
Option A — Higher Down
15% down ($44,250)
Loan amount$250,750
Monthly P&I (7%)$1,670
PMI est.$125/mo
Total monthly$1,795
Reserves after close$750
✓ Lower payment, ⚠ Almost no reserves
Option B — Lower Down
5% down ($14,750)
Loan amount$280,250
Monthly P&I (7.125%)$1,886
PMI est.$210/mo
Total monthly$2,096
Reserves after close$30,250
Higher payment, ✓ Genuine financial cushion
Option A has a lower monthly payment by $301. Option B leaves Taylor with $30,250 in liquid savings — a genuine financial cushion if the furnace dies, if she loses her job, or if the home needs immediate work. Neither is wrong. The right answer depends on Taylor's job stability, the home's condition, and her overall financial picture.
How to Decide on Your Down Payment: A Practical Framework
1
What's your minimum viable down payment?
Identify which loan programs you qualify for and the minimum requirement. This is your floor — you can't go below it.
2
What will you have left after closing?
Subtract down payment, closing costs, and moving expenses from total savings. If what remains is less than two to three months of housing costs, consider a lower down payment to preserve reserves.
3
What does PMI actually cost you — and for how long?
Calculate your PMI rate and estimate when you'll reach 80% LTV. If you're two or three years from elimination, the total cost may be far less alarming than the monthly number suggests.
4
Are there assistance programs available to you?
Research your state and local programs before committing. Grant money or forgivable loans could change your calculus entirely — and are easily missed if you don't look.
5
What's the alternative use of capital above your chosen amount?
If considering 15% instead of 10%, identify specifically what you'd do with the extra 5%. A concrete alternative is more useful than a vague sense that more down is always better.
Frequently Asked Questions
Is 20% down always better than a smaller down payment?
Not always. A larger down payment eliminates PMI, reduces your loan balance, and lowers your monthly payment — but it also ties up capital in illiquid equity, may leave you cash-poor after closing, and delays your purchase in markets where prices are rising. The optimal down payment depends on your full financial picture, not a universal rule.
Can I use gift money for a down payment?
Yes — most loan programs allow gift funds from family members for down payment and closing costs. Documentation requirements apply: the gift must be accompanied by a gift letter confirming no repayment is expected, and lenders may require bank statements showing the transfer. Rules vary slightly by loan type.
Does down payment size affect how quickly I build equity?
Yes, in two ways. A larger down payment means you start with more equity immediately, and a smaller loan means principal paydown accelerates slightly. However, home appreciation affects equity equally regardless of down payment size — a home that appreciates $30,000 adds $30,000 in equity whether you put 3% or 20% down.
Can I buy a home with no down payment if I'm not a veteran?
USDA loans offer 0% down for qualifying buyers in eligible rural and suburban areas, with income limits. Some state and local down payment assistance programs effectively cover the entire down payment requirement through grants or forgivable loans. Options exist — they require research and eligibility verification.
How does down payment size affect my debt-to-income ratio for approval?
Down payment size affects your loan amount, which affects your proposed monthly payment, which feeds into your DTI calculation. A larger down payment produces a smaller loan and lower monthly payment, which can push a borderline DTI into approval territory. If DTI is a constraint, increasing your down payment is one lever to address it.
