REITs in Your Portfolio: How Much?
REITs sit between stocks and bonds: equity-like returns with a fatter dividend and a different rhythm. Most investors land on a 5-15% sleeve. Here's how to size it.
Don't have time? Here's what you need to know:
- 1A broad index fund holds only ~2-4% real estate, so you must overweight deliberately to make REITs matter.
- 2Most investors target 5-15% of equities in REITs; Swensen's model used 15% as a core allocation.
- 3REITs are rate-sensitive and have fallen with stocks in 2008 and 2020 — they are a diversifier, not crash insurance.
- 4REIT dividends are taxed as ordinary income, so they belong in a tax-advantaged account when possible.
Why Carve Out a REIT Sleeve at All
Real estate investment trusts own income-producing property — apartments, warehouses, data centers, cell towers, shopping centers — and by law must distribute at least 90% of taxable income to shareholders. That structure is why a broad REIT fund tends to yield more than the S&P 500, often in the 3-4% range historically versus roughly 1.5-2% for the broad market.
A common objection is that you already own real estate through a total-market fund. That is partly true: REITs make up only around 2-4% of a cap-weighted index like the S&P 500. If you want real estate to actually move the needle in your portfolio, you have to overweight it deliberately with a dedicated REIT position rather than relying on the sliver baked into your stock index.
How Much Is Right: The 5-15% Range
There is no single correct number, but the practical consensus among portfolio builders lands between 5% and 15% of the equity portion of a portfolio. David Swensen, the late Yale endowment manager, famously suggested a 15% REIT allocation in his model portfolio for individual investors, treating real estate as a distinct asset class alongside domestic and foreign stocks.
A reasonable way to think about it: 5% is a light tilt that nudges your yield up modestly, 10% is a meaningful diversifier most investors are comfortable with, and 15% is an aggressive real-estate stance for someone who specifically wants property exposure and the income that comes with it. Going much beyond 15% concentrates your portfolio in one rate-sensitive sector and starts to undercut the diversification you were buying it for.
| REIT weight | Profile | What it does |
|---|---|---|
| ~5% | Light tilt | Small yield and diversification bump |
| ~10% | Moderate | Real estate becomes a genuine sleeve |
| ~15% | Swensen-style | Real estate treated as a core asset class |
| >20% | Concentrated | Sector-bet territory, less diversified |
Tip: Express your REIT target as a share of your stocks, not your whole portfolio. A '10% REIT' investor with a 60/40 split is really putting about 6% of total assets into real estate.
The Diversification Case (and Its Limits)
REITs are appealing because they have historically had less-than-perfect correlation with the broad stock market. Property values and rents respond to local supply, lease cycles, and interest rates rather than tracking corporate earnings tick for tick, so a REIT sleeve can zig when stocks zag and smooth your ride a little.
The honest caveat is that this diversification weakens exactly when you most want it. In the 2008 financial crisis and again in the COVID crash of 2020, REITs fell hard alongside stocks — correlations spike in panics. REITs are also acutely sensitive to interest rates: because they carry debt and compete with bonds for yield-seeking buyers, rising rates have historically pressured REIT prices. Treat the sleeve as a long-run diversifier, not as crash insurance.
Important: Don't expect REITs to cushion a market crash. They are equities with leverage and rate sensitivity, and they have repeatedly fallen with stocks in major downturns.

Funds to Build the Sleeve
For most people a single broad, low-cost fund is enough. VNQ (Vanguard Real Estate) is the largest U.S. REIT ETF and holds the bulk of the domestic property market at a low expense ratio. SCHH from Schwab and USRT from iShares are comparable U.S. options. If you want to round out the exposure globally, VNQI covers international real estate outside the United States.
Whichever you choose, you do not need more than one or two REIT funds — they own overlapping property sectors and stacking them just adds complexity. You can see the full list of options in our real estate ETF picks.
Mind the Tax Treatment
REIT dividends are mostly taxed as ordinary income rather than at the lower qualified-dividend rate that applies to most stock dividends. That makes a REIT sleeve relatively tax-inefficient in a regular taxable brokerage account, where those distributions get taxed at your full marginal rate every year.
The clean fix is location. Holding REITs inside a tax-advantaged account — a Roth IRA, traditional IRA, or 401(k) — shelters that ordinary-income stream from annual taxation. If you have both account types, a common move is to keep your REIT allocation in the tax-advantaged bucket and let more tax-efficient stock index funds sit in the taxable account.
Tip: If you can choose, hold your REIT sleeve in a Roth or traditional IRA so the high, ordinary-income dividends compound without an annual tax drag.

Frequently Asked Questions
Do I need REITs if I already own a total stock market fund?
You already own a little — real estate is only about 2-4% of a cap-weighted U.S. index, so a total-market fund gives you a token amount. If you want real estate to be a meaningful diversifier with a real income contribution, you need to overweight it deliberately with a dedicated REIT fund like VNQ. Owning a total-market fund alone leaves you with barely any property exposure.
What percentage of my portfolio should be REITs?
Most investors land between 5% and 15% of their equity allocation. Five percent is a light tilt, 10% makes real estate a genuine sleeve, and 15% (the level David Swensen suggested) treats it as a core asset class. Pushing much past 15% turns a diversifier into a concentrated bet on one rate-sensitive sector.
Why do REITs fall when interest rates rise?
Two reasons. REITs carry significant debt to buy property, so higher rates raise their borrowing costs and squeeze margins. They also compete with bonds for income-focused buyers, so when bond yields rise, REIT dividends look less attractive and prices adjust downward. This rate sensitivity is one of the defining features of the asset class.
Should I hold REITs in a taxable or retirement account?
Favor a retirement account. REIT dividends are largely taxed as ordinary income rather than at the lower qualified-dividend rate, so holding them in a taxable account creates an annual tax drag. Sheltering them in a Roth IRA, traditional IRA, or 401(k) lets that income compound untaxed each year.
