How to Save for a Down Payment: A Realistic Plan
Set a real savings target (down payment, closing costs and co-op reserves), choose safe places to hold it, use IRA first-home rules and see how long it takes.
6 min read · Updated
To save for a down payment, first set the full cash target (down payment plus closing costs plus any reserves a lender or co-op board requires), then automate a fixed monthly transfer into an insured savings account, CD or short-term Treasury bills. At $2,000 a month, a $100,000 goal takes about four years before interest; the table below shows other incomes and targets.
In New York City the target is usually bigger than the down payment alone, especially for co-ops. Getting that number right first saves you from finding the right apartment and being short on cash.
At a glance
- IRA first-home withdrawal
- Up to $10,000
- Lifetime, no 10% penalty (income tax may still apply)
- FDIC insurance
- $250,000
- Per depositor, per bank, per ownership category
- T-bill minimum
- $100
- Interest exempt from NY state and city income tax
- Typical co-op down payment
- 20%
- Many buildings ask more; set by each board
Step 1: Set the real target
Your cash target has three parts:
- Down payment. Loan programs set the minimum, but NYC co-op boards often set a higher one. Industry source Hauseit says 20% is the most common co-op minimum, with 25%, 35% and 50% also seen. See how much down payment you need.
- Closing costs. NYC buyers pay lender fees, title costs, attorney fees and, depending on price and property type, the mansion tax and mortgage recording tax. Estimate yours with the NYC closing cost calculator.
- Reserves. Co-op boards often want 1 to 2 years of mortgage plus maintenance left in liquid assets after closing, according to Hauseit. Lenders may also require reserves. Even with a condo or house, keep an emergency fund (try the homeowner emergency fund calculator).
| Item | Amount |
|---|---|
| Down payment (20%) | $140,000 |
| Closing costs (placeholder; estimate yours with the calculator) | $15,000 |
| 12 months of P&I ($3,540) + maintenance ($1,800) | $64,080 |
| Total cash needed | $219,080 |
The payment above assumes a $560,000, 30-year loan at an illustrative 6.5% (not a quote). The point is the shape: in a co-op, the reserve can add almost half again to the down payment.
Step 2: How long will it take?
The table below is simple math: target divided by monthly savings, with no interest or investment growth. Interest will shorten it a little; raises, bonuses or gifts can shorten it more.
| Gross income / savings rate | Monthly saving | $50,000 | $100,000 | $200,000 |
|---|---|---|---|---|
| $75,000 at 10% | $625 | 80 | 160 | 320 |
| $75,000 at 20% | $1,250 | 40 | 80 | 160 |
| $125,000 at 10% | $1,042 | 48 | 96 | 192 |
| $125,000 at 20% | $2,083 | 24 | 48 | 96 |
| $200,000 at 10% | $1,667 | 30 | 60 | 120 |
| $200,000 at 20% | $3,333 | 15 | 30 | 60 |
| $300,000 at 15% | $3,750 | 14 | 27 | 54 |
| $300,000 at 20% | $5,000 | 10 | 20 | 40 |
If the months look long, the levers are the target (a lower price, a condo instead of a strict co-op, a low-down-payment loan) and the monthly amount. Plug your own numbers into the down payment savings calculator.
Step 3: Where to keep the money
Money you plan to spend in the next few years should be safe and easy to reach. Stocks can fall right when you find the apartment. These are the usual low-risk choices:
| High-yield savings | Bank CD | Treasury bills | |
|---|---|---|---|
| Government backing | FDIC insurance | FDIC insurance | Backed by the US Treasury |
| Access | Any time | Penalty if broken early | At maturity, or sell before |
| Rate | Variable | Fixed for the term | Set at each auction |
| NY and NYC income tax on interest | |||
| Good for | Emergency fund, money needed soon | A known closing date | Rolling 4–52 week ladders |
- FDIC insurance covers up to $250,000 per depositor, per insured bank, per ownership category. If your savings and a partner's are near that amount, a joint account, separate accounts or a second bank can keep everything covered.
- Treasury bills mature in 4, 6, 8, 13, 17, 26 or 52 weeks, start at $100 and are sold at a discount or at face value; you get face value at maturity. Their interest is federally taxed but exempt from state and local income tax, which matters with NYC's city income tax. T-bills are not FDIC-insured; they are backed by the Treasury itself.
- Brokerage "cash" and money market funds are not bank deposits. The FDIC does not insure stocks, bonds, mutual funds or Treasury securities, even when you buy them through a bank. Know what you hold.
Step 4: Retirement accounts (use with care)
The IRS lets a first-time homebuyer take up to $10,000 out of a traditional IRA without the 10% early withdrawal penalty. Per IRS Publication 590-B:
- It is a lifetime limit of $10,000. If both spouses are first-time buyers, each can use up to $10,000.
- You must spend the money on buying, building or rebuilding the home (including normal closing costs) within 120 days.
- The home can be for you, your spouse, or your or your spouse's child, grandchild, parent or other ancestor.
- The person buying counts as a "first-time homebuyer" if they had no present interest in a main home during the two years ending on the purchase date. If they are married, their spouse must meet the same test.
- The exception waives the penalty, not income tax. A traditional IRA withdrawal is still generally taxable income.
- It applies to IRAs (including SEP and SIMPLE IRAs), not to 401(k)s and other employer plans, according to the IRS.
Roth IRAs work differently. Your own regular contributions can come out tax-free at any time. Earnings come out tax- and penalty-free for a first home only if the account is past its five-year holding period. Retirement money you take out now stops growing for retirement, and some co-op boards count retirement accounts toward liquidity anyway, so taking it out may not even help your application. Talk to a tax professional first.
Step 5: Put it on autopilot
- 1
Open a separate account
Name it after the goal. Money you can’t see in checking is easier not to spend. - 2
Automate on payday
Schedule the transfer for the day after each paycheck lands. - 3
Route windfalls
Send tax refunds, bonuses and raises straight to the fund. - 4
Check help programs
NYC HomeFirst offers down payment help to eligible first-time buyers. See if you qualify with the HomeFirst checker. - 5
Review every quarter
Re-run your target as prices, rates and your plans change.

Re-verified 2026-10-12. IRA first-home exception (up to $10,000 lifetime, 120-day rule, eligible relatives, 2-year no-ownership test, each spouse up to $10,000; not available from 401(k) or other qualified plans): IRS Pub 590-B (2025) and IRS early-distribution exceptions table (IRC 72(t)(2)(F)). Roth qualified distribution 5-year rule and tax-free return of regular contributions: Pub 590-B. FDIC: $250,000 per depositor, per insured bank, per ownership category; Treasury securities, stocks, bonds and mutual funds not FDIC-insured. T-bills: 4, 6, 8, 13, 17, 26 and 52 week terms, $100 minimum, sold at a discount or at par, interest exempt from state and local tax (TreasuryDirect). Fixed: T-bill pricing wording, first-time homebuyer test applies to the buyer (who may be a relative), FDIC exclusions now include Treasury securities. Months table and $700k co-op example ($560k at 6.5% = $3,539.58 P&I; $219,080 total) recomputed. Co-op: 20% most common down payment, 1–2 years post-closing liquidity typical (Hauseit; set by each building). Savings timelines are simple division with no interest or investment growth assumed; the 6.5% rate is illustrative.
