The median US home costs $400,000+. A 20% down payment is $80,000. Here is a realistic plan to save for a house without stopping retirement investing or giving up your entire lifestyle.
Saving for a house down payment might be the most intimidating financial goal for Millennials and Gen Z. The median existing home price in the US is over $400,000 as of 2026. Even in affordable markets, you are looking at $250,000 to $350,000. At 20% down, that is $50,000 to $80,000 you need to save, plus closing costs.
No wonder so many young people think homeownership is out of reach. But the reality is more nuanced than “save $80,000 or forget about it.” You may not need 20% down. There are assistance programs for first-time buyers. And with the right system, you can save aggressively for a home without halting your retirement investing or emergency fund.
How much do you actually need?
The 20% down payment myth
You have probably heard that you need 20% down. That is $80,000 on a $400,000 home. But 20% is not a requirement. It is one option.
Here are the actual minimums:
Conventional loan: 3% down minimum for first-time buyers (Fannie Mae HomeReady, Freddie Mac Home Possible). On a $350,000 home, that is $10,500.
FHA loan: 3.5% down with a 580+ credit score. On $350,000: $12,250. FHA loans have lower credit requirements (as low as 500 with 10% down) but require mortgage insurance for the life of the loan.
VA loan: 0% down for eligible veterans and active-duty military. No mortgage insurance.
USDA loan: 0% down for homes in eligible rural and suburban areas. Income limits apply.
The tradeoff for less than 20% down: Private Mortgage Insurance (PMI). If you put down less than 20% on a conventional loan, you pay PMI, typically 0.5 to 1.5% of the loan amount per year. On a $340,000 loan (3% down on a $350,000 home), PMI costs roughly $1,700 to $5,100/year, or $142 to $425/month.
PMI is not permanent. It drops off automatically when you reach 20% equity in the home (through payments and/or price appreciation). Many homeowners reach 20% equity within 5 to 8 years.
The math that matters: Is it better to save for 5 more years to hit 20% down, or buy now with 5% down and pay PMI? If home prices increase 3 to 5% per year while you save, the goalposts keep moving. The house that costs $350,000 today costs $405,000 in 5 years. You saved $70,000 for 20% down, but now 20% is $81,000. Meanwhile, the buyer who put 5% down 5 years ago has been building equity and their home is worth $55,000 more.
There is no universal right answer. But waiting to save 20% is not always the smart financial move, especially in appreciating markets.
Beyond the down payment: closing costs
Do not forget closing costs: 2 to 5% of the home price. On a $350,000 home, that is $7,000 to $17,500. This covers appraisal, inspection, title insurance, attorney fees, origination fees, and prepaid taxes and insurance.
Some closing costs can be negotiated (ask the seller to contribute) or rolled into the loan. But budget for at least 2 to 3% in cash.
Your total savings target
For a $350,000 home:
- 5% down payment: $17,500
- Closing costs (3%): $10,500
- Moving and immediate home expenses: $3,000 to $5,000
- Total needed: roughly $31,000 to $33,000
For a $400,000 home with 10% down:
- 10% down payment: $40,000
- Closing costs (3%): $12,000
- Moving/expenses: $4,000
- Total needed: roughly $56,000
For 20% down on $400,000:
- 20% down payment: $80,000
- Closing costs (3%): $12,000
- Moving/expenses: $4,000
- Total needed: roughly $96,000
Pick the scenario that matches your market and timeline.
Where to save your down payment money
Your down payment savings timeline determines where to keep the money:
Buying in 1 to 2 years
High-yield savings account. Earning 4 to 5% APY with FDIC insurance. Your money is safe, liquid, and earning a reasonable return. This is the default choice for most house savers.
Certificates of deposit (CDs). If you know your timeline exactly (buying in 18 months), a 12 or 18-month CD may offer a slightly higher rate than a HYSA. The tradeoff: your money is locked until the CD matures (early withdrawal penalty applies).
Do NOT invest this money in stocks. If the stock market drops 20% the year before you planned to buy, your down payment fund just lost $10,000 to $16,000. Money you need in under 2 years belongs in a savings account, not the stock market.
Buying in 3 to 5 years
HYSA for the core amount. Keep most of your down payment fund in a high-yield savings account. Safety comes first.
Conservative investments for a portion. If your timeline is 4 to 5 years and you have a high risk tolerance, you could invest 20 to 30% of your down payment fund in a conservative mix (like a 60/40 stock/bond allocation). But understand the risk: a market downturn could delay your home purchase.
I bonds. US Treasury I bonds earn a fixed rate plus inflation adjustment. They cannot lose value. The catch: you cannot redeem them for the first 12 months, and redeeming before 5 years forfeits the last 3 months of interest. Good for 2 to 5 year timelines.
Buying in 5+ years
If homeownership is more than 5 years away, focus on your investment portfolio (Roth IRA, 401(k)) and save for the house in a HYSA alongside your regular investing. You have time for your investments to grow and for your income to increase.
The Roth IRA has a useful provision: you can withdraw contributions (not earnings) at any time for any reason, penalty-free. And first-time homebuyers can withdraw up to $10,000 in earnings penalty-free (but you owe income tax on the earnings). This makes the Roth IRA a flexible tool for people who are not sure if they will buy in 3 years or 7 years.
How to save $30,000 to $80,000 (realistic timelines)
Here is what different monthly savings amounts produce:
| 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 numbers exclude HYSA interest (which adds roughly 4 to 5% per year on the growing balance).
If you earn $70,000/year (roughly $4,500/month after taxes) and your essential expenses are $3,000/month, saving $1,000/month for 3 years gets you to $36,000. That is enough for 10% down plus closing costs on a $300,000 home.
Strategies to accelerate your savings
Automate a dedicated “house fund”
Open a separate high-yield savings account labeled “House Fund.” Set up automatic transfers on payday. This money does not go into your regular savings or checking. Keeping it separate reduces the temptation to dip into it and makes progress visible.
Save your raises and bonuses
Every raise, bonus, tax refund, and windfall goes to the house fund. A $3,000 annual bonus redirected to savings for 3 years is $9,000 toward your down payment without touching your regular budget. Your tax refund is another lump sum opportunity.
Reduce your biggest expenses temporarily
Housing and transportation consume 50 to 60% of most budgets. Temporarily downgrading one or both can supercharge your savings:
Getting a roommate saves $500 to $1,000/month. In 2 years: $12,000 to $24,000. Driving a paid-off used car instead of a car with a $450/month payment saves $450/month. In 2 years: $10,800. Moving to a cheaper apartment saves $200 to $500/month. In 2 years: $4,800 to $12,000.
These are temporary sacrifices. Two years of a roommate to buy a home you will own for 10+ years is a trade most people would take.
Add income with a side hustle
If you can earn $500 to $1,000/month from a side hustle and direct 100% of it to your house fund, you add $12,000 to $24,000 in 2 years. Combined with your regular savings, this can cut your timeline in half.
Use cash back rewards
Your regular spending generates cash back that can be directed to your house fund. At $350 to $450/year in cash back from a good card, that is $700 to $900 over 2 years. Not a game-changer, but every bit helps.
Should you stop investing to save for a house?
This is one of the most debated questions in personal finance. Here is our take:
Do NOT stop: Contributing to your 401(k) up to the employer match. That is an instant 50 to 100% return. No house savings timeline justifies skipping free money.
Consider pausing (temporarily): Additional retirement contributions beyond the match (extra 401(k), Roth IRA) if your home purchase timeline is 2 to 3 years and you need every dollar to reach your down payment goal.
Example: You earn $75,000, contribute 6% to your 401(k) (with 3% match), and want to save for a $350,000 home with 10% down. You need $47,000 in 3 years.
- 401(k): Continue contributing 6% ($4,500/year, $375/month). Your employer adds $2,250/year.
- Roth IRA: Pause the $583/month and redirect to house fund.
- Monthly house savings: $583 (former Roth) + $500 (budget savings) = $1,083/month
- In 3 years: roughly $39,000 + HYSA interest. Close to your goal.
After you buy the house, resume Roth IRA contributions immediately. The gap of 2 to 3 years in Roth contributions is not ideal but is a reasonable tradeoff for homeownership. You can also make extra Roth contributions in future years (up to the annual limit) to partially catch up.
First-time homebuyer programs
If this is your first home purchase (or you have not owned a home in the past 3 years), you may qualify for assistance:
FHA loans: 3.5% down, lower credit requirements, government-backed.
Conventional 97/HomeReady/Home Possible: 3% down conventional loans for first-time buyers. Lower PMI rates than FHA in many cases.
State and local down payment assistance (DPA) programs: Many states, counties, and cities offer grants, forgivable loans, or matched savings programs for first-time buyers. These can provide $5,000 to $20,000+ toward your down payment. Check your state’s housing finance authority website.
Employer assistance: Some employers (particularly large tech companies, hospitals, and government agencies) offer homebuying assistance as an employee benefit. Check with HR.
IRA first-time homebuyer exception: You can withdraw up to $10,000 from a Traditional IRA without the 10% early withdrawal penalty (you still owe income tax) for a first home purchase. From a Roth IRA, you can withdraw contributions anytime tax and penalty-free, plus up to $10,000 in earnings penalty-free for a first home (earnings are taxed as income).
How much house can you afford?
A common guideline: your total monthly housing cost (mortgage, taxes, insurance, PMI, HOA) should not exceed 28% of your gross monthly income. Your total debt payments (housing + car + student loans + credit cards) should not exceed 36%.
On a $75,000 salary ($6,250/month gross):
- 28% housing: $1,750/month maximum
- At current mortgage rates (roughly 6.5%), $1,750/month supports a home price of roughly $300,000 to $330,000 with 10% down
On a dual income of $120,000 ($10,000/month gross):
- 28% housing: $2,800/month maximum
- Supports roughly $400,000 to $450,000 with 10% down
These are maximums, not targets. Buying below your maximum leaves more room for savings, investing, and living your life. A house you can comfortably afford is better than the biggest house a bank will approve you for.
Frequently asked questions
Is it better to rent or buy? It depends on how long you will stay, local rent vs. buy ratios, and your financial situation. Generally, buying makes sense if you plan to stay at least 5 to 7 years (to recoup closing costs through appreciation and equity building). Use a rent vs. buy calculator with your local numbers.
Should I wait for home prices to drop? Trying to time the housing market is like trying to time the stock market. Prices could drop, stay flat, or keep rising. Over the long term, home prices have generally increased 3 to 5% annually. If you can afford a home now and plan to stay 7+ years, waiting for a dip is a risky bet.
Can I use my 401(k) for a down payment? You can take a 401(k) loan (up to $50,000 or 50% of your vested balance, whichever is less) and repay yourself with interest. This avoids taxes and penalties but reduces your retirement investment growth while the loan is outstanding. It is better than a 401(k) hardship withdrawal (which triggers taxes + 10% penalty), but worse than saving in a dedicated house fund.
What credit score do I need to buy a house? FHA: 580+ for 3.5% down (500+ with 10% down). Conventional: 620+ minimum, but 740+ gets the best interest rates. Spend 6 to 12 months improving your score before applying for a mortgage if you are below 740.
How much should I have in savings AFTER buying? After the down payment, closing costs, and moving expenses, you should still have 3 to 6 months of expenses in your emergency fund. Homeownership comes with surprise costs (appliance failures, plumbing issues, roof repairs). Do not drain your emergency fund for the down payment.
The bottom line
Saving for a house is a marathon, not a sprint. Set a realistic target (you probably do not need 20% down), open a dedicated HYSA, automate your savings, and give yourself 2 to 4 years. Use every raise, bonus, and side hustle dollar to accelerate the timeline.
Do not stop investing for retirement entirely. Keep the 401(k) match at minimum. And do not buy more house than you can afford just because a lender says you qualify for a larger loan. The best home purchase is one that lets you keep building wealth afterward.
Start your house fund this week. Even $200/month is $4,800 in 2 years. Add to it as your income grows, and the down payment goal that feels impossible today becomes a specific date on your calendar.
