Investing HOA Reserve Funds: What's Allowed and What Isn't

HOA reserve funds belong in four places: FDIC-insured high-yield savings or money market deposit accounts, insured certificates of deposit, U.S. Treasury securities, and — where state law and your governing documents allow — government money market funds. Stocks, crypto, corporate bonds, and anything else that can lose principal are off-limits, because when you're investing HOA reserve funds — other people's roof money — fiduciary duty puts safety and liquidity ahead of yield. The boring menu still pays real money right now: the best insured accounts and short Treasuries yield around 4 percent as of July 2026, while the average bank savings account pays 0.38 percent. On a $210,000 reserve balance, that's the difference between roughly $8,400 a year in interest and roughly $800.

This article covers the rules — what boards can and can't buy — compares the four vehicles, and walks through the one technique generic advice always misses: laddering maturities against your community's actual spending schedule, so the paving money matures the year the paving happens. It ends with an eight-clause investment policy your board can adopt at its next meeting. If you're still working out how much to save rather than where to park it, start with our reserve fund guide and come back.

Safety, Liquidity, Yield — In That Order

Board members are fiduciaries, and in most states that means the prudent-person standard from the state's nonprofit corporation law: handle association money with the care an ordinarily prudent person would use in a like position. California spells it out in Corporations Code section 7231, and its Civil Code section 5515 separately requires boards to exercise "prudent fiscal management" in maintaining the integrity of the reserve account. For investing, prudence collapses into a strict hierarchy:

• Safety first. Reserve money exists to replace roofs and roads on a known schedule. It cannot be exposed to loss of principal. This isn't hypothetical caution — a board that parked reserves in a diversified bond fund at the start of 2022 watched the U.S. aggregate bond index lose about 13 percent that year. Bond funds have no maturity date and no guarantee; individual insured CDs and Treasuries held to maturity do.
• Liquidity second. The money has appointments to keep. An investment that can't be converted to cash by the date your reserve plan says the roofer gets paid is the wrong investment, whatever it yields.
• Yield third. Third, not never. Once safety and liquidity are locked, leaving six figures at 0.38 percent is its own form of waste — the gap between the average account and a 4 percent insured one is thousands of dollars a year that owners otherwise pay through dues.

The test is never whether a risky investment might have worked out. It's whether a prudent fiduciary would gamble the roof money at all. No board has ever been sued for earning 4 percent in an insured account.

The Rules for Investing HOA Reserve Funds

Three layers of rules apply, and the strictest one wins.

State statute. A few states now say it directly. Florida's HB 913, effective July 1, 2025, amended Fla. Stat. §718.112 so condominium reserve funds may be deposited or invested in certificates of deposit and depository accounts at banks and credit unions without a unit-owner vote, and requires boards to use best efforts to make prudent investment decisions that weigh risk and return — part of the same post-Surfside overhaul covered in our Florida reserve study requirements guide. California has no permitted-investment list; boards fall back on the prudent-person duty above. Most other states are silent, which is not a license to speculate — it means the general fiduciary standard governs, and courts read it conservatively when the money belongs to a community.

Governing documents. Many CC&Rs and bylaws restrict association funds to federally insured accounts. Read yours before opening anything at a brokerage — a money market fund purchase can violate documents even where state law is silent.

Your own policy. The investment policy your board adopts (template below) is the third layer, and for most communities the practical one, because it's what the next treasurer actually reads.

Whatever the layers allow, the off-limits list is settled practice across the industry:

• Stocks and equity funds — a 20 percent drawdown the year the roof fails is a special assessment you caused.
• Crypto — no insurance, no principal protection, no defensible fiduciary argument.
• Corporate and municipal bonds — credit risk for a yield pickup measured in fractions of a percent.
• Bond mutual funds and ETFs — even government ones; no maturity date means no guaranteed principal on your spending date.
• Annuities and insurance products — surrender charges are the opposite of liquidity.
• Anything the board can't explain in one sentence at an open meeting.

The Four Vehicles, Compared

High-Yield Savings and Money Market Deposit Accounts

The best high-yield savings and money market deposit accounts pay roughly 4.0 to 4.2 percent APY as of July 2026 — against a national average savings rate of 0.38 percent, which is about what the default business savings account at your current bank pays. These are FDIC-insured to $250,000, same-or-next-day liquid, and variable-rate. They're the right home for your liquidity sleeve: the cushion for surprises and near-term expenses. Business accounts sometimes pay slightly less than the consumer teaser rates, so get the business rate in writing.

Certificates of Deposit

Top 1-year CDs pay about 4.0 to 4.15 percent and 2-year CDs about 4 percent right now. The rate is locked, which is the point — you're buying certainty that the paving money will be there. The trade is an early-withdrawal penalty, typically three to twelve months of interest, so a CD should never mature after the date you need the cash.

The constraint to manage is FDIC's $250,000 limit — per depositor, per bank, per ownership category. Your association is one depositor, so the operating account, the reserve savings, and a CD at the same bank all aggregate toward a single $250,000. Two workarounds: spread accounts across multiple banks yourself, or ask your bank about IntraFi's ICS and CDARS programs, which split a large deposit into sub-$250,000 pieces across a network of more than 3,000 institutions while you deal with one bank and one statement. Credit unions offer the same math under NCUA insurance, also $250,000.

U.S. Treasury Securities

Treasury bills (4 to 52 weeks) and notes (2 to 10 years) are backed by the full faith and credit of the federal government, which makes the $250,000 problem disappear entirely — there is no insurance cap because there is no insurance needed. The 2-year note yields about 4.15 percent as of early July 2026, competitive with the best CDs. Treasuries also trade on a deep secondary market, so unlike a CD you can sell before maturity if plans change (at the market price, which can be above or below what you paid), and interest is exempt from state income tax. Buy them through a brokerage account opened in the association's name; TreasuryDirect entity accounts exist but are clumsy for boards with rotating officers.

Money Market Mutual Funds

Government money market funds yield around 4 percent and hold Treasuries and government-backed paper, but they are securities, not deposits — not FDIC-insured. SIPC coverage at the brokerage protects against the broker failing, not against the fund losing value. Some governing documents and insured-only state rules exclude them, so check your layers first. Their legitimate role is as the sweep vehicle inside the brokerage account where your Treasuries live, holding coupon payments and maturing proceeds between purchases.

Ladder Maturities to Your Spending Schedule

Bank marketing will tell you to build a 12-month CD ladder with equal rungs. That's designed for a household's rainy-day fund, not an HOA. Your association owns something better: a reserve plan that already says, year by year, when money leaves the account. Ladder to that schedule — the same expenditure timeline that drives the cash-flow funding method.

Take a 90-home townhome community with $210,000 in reserves and $30,000 a year in contributions. Its component plan shows an $80,000 asphalt overlay in summer 2029, a $150,000 roof replacement in 2032, and about $15,000 of smaller items over the next two years. The ladder writes itself:

• Liquidity sleeve — $35,000 in a high-yield money market account at about 4 percent. Covers the near-term small items plus surprises.
• Paving bucket — $80,000 in a CD or Treasury note maturing March 2029, a few months before the overlay bids go out. At 4 percent, it earns roughly $9,000 by maturity — paving money that shows up on its own.
• Roof bucket — $95,000 split into rungs maturing 2028 and 2031 and rolled forward at each maturity, with a slice of each year's contributions buying new rungs, so about $150,000 lands liquid by early 2032.

Blended, the whole $210,000 earns about $8,400 a year instead of $800 — and every dollar of it is reserve funding that raises your percent funded without touching dues. Four rules keep the ladder honest:

• Mature 60 to 90 days before the projected bill. Contractors want deposits before final invoices, and projects start early more often than boards expect.
• Never buy past the need date. One broken CD penalty can erase years of yield advantage over a savings account.
• Keep 10 to 20 percent liquid — roughly a year of contributions — for the component that fails off-schedule.
• Re-run the ladder every year when the reserve study updates. If your study is stale, do a DIY update first; our reserve fund calculator will turn your component list into the year-by-year expenditure schedule the ladder needs.

This is the piece the management-company blog posts skip, because it requires knowing your community's spending timeline. But it's exactly the knowledge your board already paid for when it bought a reserve study. Use it.

Don't Forget: Reserve Interest Is Taxable

Dues are tax-exempt function income for an HOA, but interest is not. On Form 1120-H — the one-page return most associations file — interest is taxed at a flat 30 percent (32 percent for timeshares) after a $100 deduction. The example community's $8,400 of interest generates a federal tax bill of about $2,500. Filing the regular Form 1120 drops the rate to 21 percent but brings corporate-return complexity most volunteer boards shouldn't want; our HOA tax filing guide walks through the trade-off. Budget the tax as a line item and move on — keeping 70 cents of every interest dollar still beats earning nothing at all.

Write a One-Page Investment Policy

An investment policy turns all of the above from one treasurer's good judgment into an institution that survives board turnover. Eight clauses cover it:

• 1. Objectives. Reserve funds shall be invested for safety of principal first, liquidity second, and yield third.
• 2. Permitted investments. FDIC- or NCUA-insured deposit accounts and certificates of deposit; U.S. Treasury bills and notes; government money market funds if the governing documents allow.
• 3. Prohibited investments. Equities, corporate and municipal bonds, bond funds and ETFs, cryptocurrency, annuities, and any instrument with principal risk or a maturity beyond clause 5.
• 4. Insurance limits. No more than $240,000 per insured institution across all association accounts, leaving headroom for accrued interest under the $250,000 cap. U.S. Treasuries are exempt from this limit.
• 5. Maturity matching. No instrument shall mature later than the date the current reserve plan projects the funds will be needed, and none beyond five years.
• 6. Authority. New institutions and accounts require a board resolution; moving reserve funds requires the signatures of two officers.
• 7. Reporting. A schedule of all holdings — institution, balance, rate, maturity date — appears in the monthly board packet, reconciled to statements.
• 8. Annual review. The board re-adopts this policy each year alongside the budget and the reserve study update.

Put it on one page, vote on it at an open meeting, and attach it to the minutes. That 20 minutes of governance is what stands between your community and the next treasurer's brilliant idea.

Controls That Keep the Money Safe

Most HOA money that disappears isn't lost to bad investments — it's embezzled through accounts one person controlled. The investment side needs the same controls as the rest of your finances:

• Separate reserve accounts from operating. Different account numbers at minimum; several states require it, and it makes borrowing from reserves visible instead of accidental.
• Dual signatures and written approval for transfers. California's Civil Code section 5502 requires prior written board approval for transfers above the lesser of $5,000 or 5 percent of the estimated income in the annual budget for associations of 50 or fewer homes ($10,000 for larger ones). It's a sensible threshold even where it isn't law.
• Monthly reconciliation by someone who isn't a signer. Statements go to a second officer, get reconciled, and appear in the board packet — the same discipline covered in our financial reporting guide.

Put the Cash to Work This Quarter

The whole project is smaller than it looks: pull your reserve plan's expenditure schedule, open one high-yield account and one CD or Treasury position matched to your next big project, adopt the eight-clause policy, and add the holdings schedule to the board packet. A treasurer can do it in an afternoon plus one board vote. If you'd rather keep the moving parts in one place — components, balances, and the year-by-year spending schedule your ladder maturities hang on — our Reserve Planner maintains that timeline for you as costs and dates shift, though it complements a professional reserve study rather than replacing one.

Either way, stop letting six figures sit at 0.38 percent. The safest investment menu in American finance currently pays ten times that, and your community's roofs are counting on the difference.
