We sold our starter condo and have $120,000 in cash sitting in a 0.01% checking account. We are renting right now and plan to buy our forever family home in about 3 to 4 years.
We are completely split on what to do:
- My brother-in-law says inflation will eat it alive and we should put 100% into high-growth tech stocks / QQQ so it doubles by 2029.
- My parents say the stock market is gambling and we must lock 100% into bank CDs or a savings account.
We can't afford to lose this down payment, but sitting in 0.01% checking feels terrible.
1. For a 3–4 year timeline with a fixed goal (house down payment), what is the coarse asset allocation shape across Cash, Bonds, and Equities (conservative vs progressive)?
2. What are the trade-offs/risks of putting medium-term down payment money into high-concentration equities?
3. What concrete screening steps should we follow before committing any money?
Answer
For your stated constraint ("can't lose the down payment") on a 3–4 year fixed goal, the conservative end of the 2–5 year band is the closer fit; the progressive shape only works if you have other stable savings outside this pool. The table and the conditions for each row are below.
**Q1 — Coarse shape (2–5 year horizon)**
| | Cash | Bonds | Equities |
|---|---|---|---|
| Conservative | 30–60% | 30–50% | 10–30% |
| Progressive | 15–40% | 20–40% | 30–55% |
These are interval bands, not points. You're closer to the conservative row if a 10–15% drop would force you to delay the purchase, or if this $120k is your only cushion beyond a separate emergency fund. You're closer to the progressive row only if you have other stable savings outside this pool and a 20–30% drawdown wouldn't push your home-buying timeline out by a year.
**Q2 — isks of putting a 3–4 year down payment into high-concentration equities**
- **Time-horizon mismatch.** 3–4 years is short. Equity drawdowns have historically taken 3–5 years to recover; a 2000-style or 2008-style drawdown in year 3 could leave you buying the house with less than you started with.
- **Sequence-of-returns risk.** A bad year right before you need the money hurts far more than a bad year in year 1. Entry into the Nasdaq-100 in early 2022, for example, didn't get back to flat until late 2023.
- **QQQ specifically is concentrated, not broad-based.** Nasdaq-100 is ~100 names, heavily weighted in a handful of tech mega-caps. It's a sector-and-factor bet, not a "the market" bet. If tech underperforms for two years, you feel it disproportionately.
- **The "doubles by 2029" line is a forward prediction, not a fact.** Past QQQ returns have been strong; they aren't guaranteed. I can't verify or refute that specific number, and you shouldn't plan a non-negotiable purchase around it.
- **Inflation is real, but smaller than the downside.** 3–4 years of inflation might erode roughly 8–12% of purchasing power. A 30% equity drawdown in the wrong year erodes more. When the goal date is fixed, "don't lose the down payment" usually beats "beat inflation."
**Q3 — Screening steps before committing any money**
Each line is something you can verify yourself on a product page or your own account — not a recommendation.
1. **Account before product.** Decide where this money sits first: taxable brokerage, oth IA, 401(k), etc. Each has different tax treatment and different rules about withdrawal for a home purchase. Check the IS rules page for the account type you're considering.
2. **If you hold equities, broad-based only.** Sector, theme, or single-industry ETFs (Nasdaq-100 included) are concentrated bets. For broad equity exposure, look at total-market or S&P 500-style index funds.
3. **Don't pay three times for the same exposure.** QQQ plus a tech-sector ETF plus a handful of large-cap tech stocks is the same bet three times. Compare top-10 holdings across anything you consider.
4. **Expense ratio vs. peers.** Compare 2–3 candidates in the same category.
5. **Liquidity matches the use date.** If part of this goes into bonds or CDs, the maturity ladder should land near when you actually plan to make an offer. Early-withdrawal penalties on CDs can erase a year of interest.
6. **Currency.** USD throughout, no FX concern as written. If anything you consider is denominated in another currency, the conversion eats into the return.
7. **Single-name concentration is your call + your cost.** Going heavy on one stock or one sector ETF is a deliberate bet. The cost is the volatility pattern in Q2 above.
**On the two camps at your table**
The disagreement is really about which risk dominates — inflation over 3–4 years, or a drawdown in years 3–4. Both are real. The shape that fits "can't lose the down payment" is not 100% of either extreme; it's a mix where the bond/cash portion absorbs the inflation drag while the equity portion stays small enough that a drawdown won't sink the purchase.
**One factual note for the parents' side:** your current 0.01% checking is well below what FDIC-insured high-yield savings accounts typically pay at US banks in 2026. Not a recommendation to switch — a fact for them to verify at whatever institution they're considering. CDs and savings accounts are different products with different liquidity and penalty rules; both should be checked against the standard FDIC coverage limit on the bank's own disclosure page.
**Final call — yours**
Which mix, which account, which specific products. The screening list above is what to verify before you commit; it doesn't pick for you. The choice between "100% QQQ" and "100% CDs" is a false binary — the interval table is built exactly so you don't have to make that choice.
