Stock market comparison.

A reference benchmark used in 3Y reports to give projected real estate returns familiar context against broad-market U.S. equity investing.

What the comparison shows

3Y reports plot the modeled return of the analyzed property against a simplified broad-market buy-and-hold benchmark. The benchmark is meant to answer the question every individual investor eventually asks: "Would I do better just putting this money in the stock market?"

The comparison is not a guarantee. It is not an investment recommendation. It is not a prediction of future market performance. It is a plain-language reference based on the common long-term-investing assumption that broad U.S. equity returns have historically been near the high single digits annually over multi-decade windows.

The Rule of 72

The shorthand the comparison uses is the Rule of 72: divide 72 by an assumed annual return to estimate how many years it would take a balance to double. At an 8% return, money doubles roughly every 9 years. At a 12% return, every 6 years. At a 4% return, every 18 years.

This is a useful intuition pump, not a forecast. Real returns vary year to year, sometimes substantially, and sequence-of-returns risk affects how the doubling actually plays out. The Rule of 72 gives you a feel for the magnitude of compounding; it does not give you a guarantee about your specific outcome.

Why a comparison and not an answer

The right answer to "stocks vs. real estate" depends on factors 3Y can't observe — your tax situation, your appetite for active management, your existing portfolio, your liquidity needs, your time horizon, and whether you actually enjoy operating rental property. The comparison surfaces the trade-off; it doesn't resolve it. Investors should consult licensed financial professionals before making allocation decisions across asset classes.

Important note.

3Y is a decision-support platform. The figures discussed on this page are illustrative and do not constitute investment, legal, tax, insurance, or appraisal advice. 3Y's estimates are not the same as an opinion of value developed by a licensed appraiser under USPAP and should not be relied upon for lending, tax, insurance, or legal purposes.
