How to Save for a House Down Payment

The median first-time homebuyer in the US puts down 6% to 8%, not 20%. On a $350,000 home, that is $21,000 to $28,000 in down payment plus $7,000 to $17,500 in closing costs. The fastest path to that number is to set a specific target, pick a savings account that matches your timeline, and automate a monthly transfer the same day. Most savers reach a first-home down payment in 2 to 5 years.

Step 1: Set a Realistic Home Price Target

Saving without a price target leads to under-saving. Start by back-calculating from what you can afford.

The classic affordability rules:

• 28/36 rule: Housing costs (mortgage, taxes, insurance) under 28% of gross monthly income. Total debt under 36%.
• Mortgage lender DTI ceilings: 43% to 50% depending on loan program

Run your scenario through the mortgage payment calculator. Plug in your gross income, current debts, and a target interest rate. The output is the price range you can responsibly buy.

Round to the high end of comfort, not the low end. Underestimating the home price now means oversaving by 20% three years out. Overestimating by 10% costs you little.

Step 2: Pick a Down Payment Percentage

Down payment size shapes everything downstream: monthly payment, PMI, total interest, and how fast you build equity.

| Down payment | $350K home | PMI required? | Monthly P&I at 6.5% | |--------------|-----------|---------------|--------------------| | 3% conventional | $10,500 | Yes ($120 to $200/mo) | $2,144 | | 5% conventional | $17,500 | Yes ($110 to $180/mo) | $2,099 | | 10% conventional | $35,000 | Yes ($80 to $140/mo) | $1,989 | | 20% conventional | $70,000 | No | $1,768 |

PMI typically costs 0.3% to 1.5% of the loan per year. On a $315,000 loan, that is $945 to $4,725 per year, or $79 to $394 per month. PMI auto-cancels when your loan balance reaches 78% of original value.

Rule of thumb: If you can hit 10% to 15% down without delaying purchase by more than 12 months, do it. If hitting 20% means waiting 3+ years, take the PMI and start building equity now. House price appreciation often outruns the savings rate.

Step 3: Calculate the Full Cash-to-Close

The down payment is only part of what you owe at the closing table. Build the full number before you start saving.

For a $350,000 home with 10% down, plan for:

• Down payment: $35,000
• Closing costs (3.5% of price): $12,250
• Inspections (general, radon, sewer): $700 to $1,200
• Moving: $1,500 to $4,000
• First-month reserves (mortgage escrow + utilities setup): $3,500
• Initial repairs and immediate furniture: $2,000 to $10,000

Total cash-to-close: roughly $55,000 to $66,000 for a $350,000 purchase. Save the high end. Buying a home with no cash reserves is the number-one cause of stress in the first 12 months of ownership.

Step 4: Pick the Right Account for Your Timeline

The shorter your timeline, the more boring your account should be.

| Timeline | Recommended account | Why | |----------|--------------------|----| | 0 to 12 months | HYSA | Full liquidity, no rate risk | | 12 to 24 months | HYSA, optional no-penalty CD | APY edge with manageable lockup | | 24 to 36 months | 70% HYSA, 30% CD ladder | Lock part of the rate while keeping flexibility | | 36 to 60 months | 50% HYSA, 50% CD ladder | Capture higher CD rates on the locked tranche | | 60+ months | CD ladder, Treasury ladder, conservative bond fund | More room to optimize yield |

For HYSA picks, see Marcus, Ally, and SoFi. For CD options, see Fintiex CDs. To structure CDs across multiple maturities, see how to start a CD ladder.

Do not invest down payment money in stocks if you plan to buy within 3 years. The S&P 500 has had multiple 30%+ drawdowns inside any given 3-year window. A 30% drop on a $40,000 down payment is $12,000 of lost progress and 12+ extra months of saving.

Step 5: Automate the Monthly Transfer

Take your target cash-to-close and divide by your timeline in months. That is your minimum monthly transfer.

Examples:

• $40,000 in 36 months at 4.5% APY: about $1,036/month
• $40,000 in 48 months at 4.5% APY: about $760/month
• $40,000 in 60 months at 4.5% APY: about $594/month
• $60,000 in 48 months at 4.5% APY: about $1,140/month

Run your exact number on the savings goal calculator. Then set a recurring ACH transfer on the day after payday. Automate it once, audit it once a quarter.

If your gross savings rate today is under the required number, the realistic levers are: longer timeline, smaller down payment percentage, lower price target, or higher income. Pretending the math will solve itself is the slow path to burnout.

Step 6: Bank Windfalls Aggressively

A 36-month timeline assumes only regular savings. Windfalls compress timelines fast.

| Windfall | Months of progress (at $1,000/mo plan) | |----------|---------------------------------------| | $3,000 tax refund | 3 months | | $5,000 bonus | 5 months | | $10,000 gift | 10 months | | $20,000 inheritance | 20 months |

Route every windfall directly into the down payment HYSA before it touches checking. The mental anchoring is the entire fight. If $5,000 lands in checking, 30% to 60% of it gets absorbed into lifestyle. If $5,000 lands directly in the down payment account, 100% of it shortens your timeline.

The IRS publishes the gift tax exclusion limit each year (around $19,000 per donor in 2026), which matters if family is helping fund the down payment.

Step 7: Reassess Every 6 Months

Six-month checkpoints prevent silent drift. At each one, recheck:

• Home prices in your target zip code. If they have risen 5% to 10% in 6 months, either raise the target or adjust the down payment percentage.
• Mortgage rates. A 1 percentage point rate change moves the monthly payment on a $300,000 loan by about $180. That changes what you can afford.
• Your savings pace. Are you on or behind plan? If behind, do you raise the transfer or extend the timeline?
• Your APY. Is your HYSA still competitive? If your rate has slipped 0.50+ points behind the leader, switch.

For the bigger picture, the Federal Reserve's data on mortgage rates updates weekly, and the CFPB's homebuyer guide walks through closing-cost itemization.

Avoid These Three Down Payment Mistakes

1. Underestimating closing costs. A buyer who saves only the down payment and shows up $10,000 short at closing is in real trouble. Save the full cash-to-close number from day one.
2. Investing the down payment in equities. Tempting in bull markets, devastating in the bad year. Boring accounts win this race.
3. Draining the emergency fund to close. Closing should leave you with at least 1 to 3 months of expenses in reserve. The first year of homeownership comes with surprises.
