House Down-Payment Goal
House Down-Payment Goal
A house down payment is a medium-term goal, not a long-term goal—even if you're buying a home you'll keep for 30 years.
Many people confuse the house with the down payment. They think: "I'll own this house for 30 years, so I should invest the down payment aggressively." Wrong. The down payment is money you'll need in 3–7 years. The house itself is a 30-year asset (and you're not investing in it for growth—you're living in it).
The allocation for a house down payment should reflect when you'll use the money, not how long you'll own the house.
Key takeaways
- A house down payment is a medium-term goal (3–7 years), not a long-term goal
- Use a balanced allocation (40–60% stocks) with a glide-down as closing approaches
- Target 10–20% down in the U.S.; anything over 20% is nice but not required
- Account selection matters: Roth IRA contributions can be withdrawn penalty-free, HYSA works for taxable savings
- De-risk 6 months before closing to guarantee you have the exact amount needed
The timeline misconception
You find a house you love. You'll own it for 30 years. You think: "I have 30 years of equity building, so I should maximize growth in my down payment savings."
This is the opposite of correct. Your investment timeline for the down payment is not 30 years. It's however long until you close (3–7 years, typically). After closing, the down payment is irrelevant—it's become part of your home equity. You're no longer investing it; you're living in it.
Think of it this way: if you couldn't buy the house without the down payment, and you must buy it within 7 years, then the down payment is a 7-year goal. The house might be a 30-year asset, but the down payment savings goal is 7 years, max.
Down payment size: 20% is not required
Many people delay buying a house because they're trying to save 20% down. They save, and save, and save. Meanwhile, they're paying rent, rates are rising, house prices are rising, and the target keeps moving further away.
Twenty percent down eliminates PMI (private mortgage insurance), which costs 0.5–2% of the loan value annually. But it's not required to buy a house.
In 2024, conventional loans accept 3–5% down (with PMI), FHA loans accept 3.5% down (with insurance), and VA/USDA loans accept 0% down (if you qualify).
If you can afford to buy a house with 5–10% down, buy it. You'll pay PMI for 5–10 years, but you'll be building equity instead of paying rent. The math often favors buying earlier with lower down than waiting for 20%.
Example: Sarah can save $15,000 in 2 years (5% down on a $300,000 house in a HCOL area) or save $60,000 in 8 years (20% down). Her local home prices appreciate 3% annually and rent is $2,000/month.
Option A (buy in 2 years with 5% down):
- Home value at purchase: $300,000
- PMI: roughly $200/month × 120 months = $24,000 total
- Total cost: $15,000 down + $24,000 PMI = $39,000
- Home value after 8 years (2026–2034): approximately $380,000
- Equity: $380,000 - $285,000 mortgage remaining = ~$95,000
Option B (rent, buy in 8 years with 20% down):
- Rent paid for 8 years: $2,000 × 96 months = $192,000
- Down payment saved: $60,000
- Total cost: $192,000 + $60,000 = $252,000
- Home value at purchase: approximately $380,000
- Equity: $60,000 down + appreciation captured = $100,000+
Option A costs $39,000 and builds ~$95,000 in equity over 8 years. Option B costs $252,000 total and builds similar equity. Option A is dramatically cheaper.
The PMI is not evil; it's the cost of starting to build equity earlier.
Allocation for down payment: medium-term rules
Since a down payment is a medium-term goal (3–10 years), use a medium-term allocation:
3–4 years to closing: 30–40% stocks, 60–70% bonds 5–6 years to closing: 50–60% stocks, 40–50% bonds 7–10 years to closing: 60–70% stocks, 30–40% bonds
If you're buying in 5 years and have $20,000 saved, use a 50/60 stock/bond allocation. Contribute regularly (setting up automatic transfers). As closing approaches, gradually shift to bonds and then to cash.
A target-date fund matched to your closing year is perfect for this: Vanguard Target Retirement 2029 if you're closing in 2029, for example.
Account selection for down payment
Where you save the down payment matters:
Roth IRA (if you're young enough): You can contribute $7,000/year. The money grows tax-free. Here's the key: you can withdraw your contributions (not earnings) anytime, penalty-free, for any reason (including a house down payment). This is powerful.
Example: You contribute $7,000/year for 5 years ($35,000 total). The account grows to $40,000. You can withdraw the $35,000 in contributions penalty-free for your down payment. The $5,000 in earnings stays invested.
For down payment saving, maxing a Roth IRA is often the right move, especially if you're under 40.
High-yield savings account (HYSA): If you have additional down payment savings beyond what fits in a Roth IRA, keep them in a HYSA earning 4.5–5.0%. You sacrifice some growth (returns are lower than a balanced fund) but guarantee the money is safe and liquid.
Taxable brokerage account: If you have surplus savings, a taxable brokerage account with a medium-term allocation (balanced fund, target-date fund) works well. When you sell to close on the house, you'll owe capital gains tax, but the account is flexible and the returns are often worth it.
Money market account or CD (6–12 months before closing): Once you're 6–12 months from closing, shift everything to cash-equivalent (money market, CD, HYSA). You want to know the exact amount you have with zero risk.
The glide-down in practice
Here's a detailed example. You're 32 years old, you want to buy a house in 2030 (6 years away), and you need $60,000 down.
2024 (today): You have $10,000 saved. You allocate 60 stocks / 40 bonds. You contribute $8,000/year ($667/month).
2025: Your balance is approximately $20,000 (original + contribution + investment returns). Allocation stays 60/40. Contribute $8,000.
2026 (4 years to closing): Your balance is approximately $32,000. Shift allocation to 50 stocks / 50 bonds. Contribute $8,000.
2027 (3 years to closing): Your balance is approximately $45,000. Shift to 40 stocks / 60 bonds. Contribute $8,000.
2028 (2 years to closing): Your balance is approximately $57,000. Shift to 20 stocks / 80 bonds. Contribute $8,000 (now at $65,000, slightly over target).
2029 (1 year to closing): Your balance is approximately $68,000. Shift to 5 stocks / 95 bonds (nearly all cash). You're at your target.
2030 (closing year, 6 months before): Your balance is approximately $70,000. Move everything to a HYSA or money market earning 4.5%. You have your exact $60,000 (plus $10,000 buffer for closing costs) sitting safely. Zero market risk.
Closing: You withdraw $60,000, pay closing costs, and close on the house.
This systematic approach removes emotion and guarantees you have the money when you need it.
Closing costs and buffer
Don't forget closing costs. They typically run 2–5% of the purchase price.
On a $300,000 home purchase, closing costs might be $6,000–$15,000. This includes:
- Appraisal: $400–$600
- Inspection: $300–$600
- Title insurance and search: $800–$1,200
- Attorney/escrow: $500–$1,500
- Loan origination fee: $500–$2,000
- Property taxes, insurance, HOA, prorated: $2,000–$5,000
Build a buffer for these. If you need $60,000 down, save $66,000–$70,000 to cover down payment + closing costs + contingency. You don't want to fall $5,000 short two weeks before closing.
Mortgage rates and timing
Mortgage rates fluctuate. When rates are low (2–3%), buying makes sense. When rates are high (7–8%), buying is less attractive.
But rates are unpredictable. Don't delay buying (and paying rent) waiting for rates to drop. Instead, lock in a rate when you're ready to buy, and focus on the math: comparing the total cost of renting vs. owning over the period you'll stay in the house.
If you plan to stay 7+ years, buying is usually better than renting, regardless of rates. If you plan to stay 3–5 years, renting might be cheaper because of the transaction costs of buying and selling.
Geographic variation: HCOL vs. LCOL
Down payment targets vary wildly by location.
Low-cost-of-living (LCOL) area: House prices are $150,000–$250,000. A 10% down payment is $15,000–$25,000. Achievable in 2–3 years of saving for many people.
High-cost-of-living (HCOL) area (San Francisco, New York, Boston): House prices are $500,000–$1,500,000. A 10% down payment is $50,000–$150,000. This might take 5–10 years to save.
If you're in a HCOL area and a 10% down payment feels impossibly far away, consider: renting longer, moving to a lower-cost area, buying a smaller/cheaper home, buying with a partner, or buying with family help.
After you buy: down payment as leverage
Here's an underappreciated point: the down payment is leverage. You're controlling a $300,000 asset with a $60,000 investment. If the house appreciates 3% annually, your equity grows $9,000 per year on your $60,000 investment—a 15% return.
This is not an investment return (you're not selling the house); it's a leverage effect. It's why real estate is powerful for wealth building, especially after you've paid down the mortgage.
But this doesn't change the allocation for down-payment savings. You're still saving for a medium-term goal, and your allocation should reflect that timeline, not the long-term leverage of the asset.
Rent vs. buy and the down payment
The rent-vs.-buy decision is complex, but the down payment timing matters.
If buying requires saving 20% down and that takes 10 years, you're paying rent for 10 years while your peers are building equity. Worse, house prices might appreciate during those 10 years, pushing the target further away.
If buying requires only 5–10% down and you can save it in 2–3 years, you start building equity sooner, even with PMI.
The math is usually: buy when you can save the down payment (even if small) plus 6 months of mortgage payments as an emergency fund. Don't wait for 20% if it means renting for years longer.
