What is the 1% rule in real estate investing?
In one paragraph
The 1% rule states that a rental property should generate monthly rent equal to at least 1% of its purchase price — a $200,000 property should rent for at least $2,000 per month — as a quick filter for whether a deal is worth analyzing further.
What this actually means
The 1% rule is a screening heuristic, not a valuation model. Its purpose is to quickly eliminate properties that cannot plausibly cash flow before spending time on detailed due diligence. If a property's rent-to-price ratio falls significantly below 1%, the arithmetic of financing costs, taxes, insurance, maintenance, and vacancy make positive cash flow unlikely in most markets.
The rule originated in real estate markets where properties were priced at lower multiples of rental income. In high-cost coastal markets — New York, San Francisco, Seattle, Los Angeles — the 1% rule is nearly impossible to meet. A $900,000 property would need to rent for $9,000 per month to satisfy the rule, which is far above market rents for most property types. Investors who insist on the 1% rule in these markets do not invest; investors who abandon it entirely often buy properties that consume cash rather than produce it.
The more useful framing is to use the 1% rule as a starting filter and then run a full cash-on-cash return analysis on properties that clear it. Cash-on-cash return measures annual pre-tax cash flow divided by total cash invested (down payment plus closing costs plus initial repairs). A property that meets the 1% rule in a reasonable market will often produce a cash-on-cash return in the 6-10% range — materially better than most passive alternatives.
"Set for Life" by Scott Trench covers the math behind rental property screening in detail, including how to model vacancy rates, capital expenditure reserves, and property management costs. These are the numbers that determine whether a property actually cash flows, and the 1% rule alone cannot capture them.
"Rich Dad Poor Dad" by Robert Kiyosaki provides the philosophical context: the goal of real estate investing is to acquire assets that put money into a pocket rather than pull it out. A property that fails to cash flow may still appreciate, but appreciation is not guaranteed and is not the same as an income-producing asset.
Investors in high-cost markets increasingly look to secondary and tertiary markets where the 1% rule is still achievable — accepting remote management complexity in exchange for stronger cash flow metrics.
