The 1 Percent Rule in Real Estate Investing

The 1 percent rule in real estate investing says a rental is worth a closer look if monthly rent is at least about 1% of purchase price: a $200,000 house that leases for $2,000. It is a screen from a cheaper-price, cheaper-money cycle. In many metros today, sold comps and leased comps fail it by a wide margin. That does not mean those metros have no viable rentals. It means the rule is filtering almost everything out—or, worse, sending you only to the weakest streets that still “hit 1%.”

Use it as a first-pass discard if you insist. Then replace it with cash-flow and DSCR math that a financing review can actually fund.

Census and HUD data make the gap obvious at a national level even before you open a local MLS. Median home values and median gross rents in the American Community Survey do not sit at a 1% monthly ratio in most large metros; price-to-rent has been richer than that rule for years. Treat 1% as folklore unless your submarket still prints it.

The 1 Percent Rule in Real Estate Investing as a Cycle Filter

The rule “worked” as a heuristic when prices were lower relative to rents and when a conventional or investor payment at then-prevailing rates left room after taxes and insurance. Two things moved:

• Prices rose faster than rents in many job centers, so 0.5–0.7% of price is a common leased ratio on ordinary houses.
• Rates rose, so even a house that still clears 1% of price may not clear DSCR once PITIA uses today’s constant.

So the rule now fails in two opposite ways:

1. False negative. A $420,000 house renting for $2,400 (0.57%) can still cash-flow at a 35–40% down DSCR purchase if taxes and insurance are sane. The rule said no. The ledger might say yes.
2. False positive. A $120,000 house renting for $1,250 (1.04%) in a high-crime, high-capex, uninsurable pocket can ruin you. The rule said yes. The operating statement will not.

If you still want a percentage screen, use it only to sort a large MLS pull: discard the 0.3% tourist-priced houses, then underwrite the rest. Do not use it as a close.

Replace the Rule With Cash-Flow Math

Monthly cash flow ≈ rent − vacancy allowance − operating expenses − reserves − PITIA

Cash-on-cash ≈ 12 × that remainder ÷ cash in

DSCR ≈ rent ÷ PITIA (on a dedicated 1–4 unit DSCR product; commercial files use NOI ÷ debt service)

Those three numbers, with conservative vacancy and a real insurance quote, decide the bid. What is a good cash-on-cash return sets language for the equity yield. Debt service coverage on a rental and how to increase DSCR set the loan side.

A worked contrast (educational, not a quote):

	“Hits 1%”	“Fails 1%, works on math”
Price	$150,000	$360,000
Rent	$1,500	$2,350
Rule	1.00%	0.65%
Taxes + ins + HOA	$450 (old building, coastal wind)	$380
P&I at 25% down	$720	$1,620
PITIA	$1,170	$2,000
DSCR	1.28	1.18
After 7% vacancy + $150 ops	Thin or negative if capex is real	Modestly positive if ops stay $150

The 1% column can still lose once you add a roof and a vacancy. The 0.65% column can be the better business. The table is the point: the rule never saw insurance or the payment.

What to Use Instead on an MLS Pull

1. Filter by leased rent estimates you will verify, not by list price alone.
2. Estimate PITIA before you drive by. Tax assessor + a landlord insurance ballpark + 7% vacancy.
3. Compute DSCR at the down payment you will actually write. If you need 45% down to clear a 1.20 overlay, the “deal” is a cash play. Say that.
4. Walk the capex. 1% houses are often 1% because the market already subtracted a dead furnace.
5. Drop STR-only pitches unless you operate STR and the city is stable. Price the LTR fallback. See long-term rental DSCR.

Is now a good time to buy is the timing article. This one is the screen you should retire.

Where a Percentage Rule Still Helps

• Teaching new partners why a $900,000 house at $2,800 rent is probably not a cash-flow first deal.
• Sorting 200 listings in a secondary metro that still has a fat tail of cheap stock.
• Sanity-checking a seller’s rent claim. If they need 1.4% of asking price in rent to make their story work, they are selling a dream.

It does not help you choose between two 0.6% houses. That is underwriting.

Five-to-eight-unit “1% buildings” are especially misleading: one vacancy is 12–20% of the roll, and those files typically expect experienced operators. Do not let a percentage talk you into your first apartment.

Frequently Asked Questions

Does the 1 percent rule still work?

As a close, rarely in high-price metros. As a fast discard of extreme price-to-rent outliers, sometimes. Financing decisions should use PITIA, vacancy, and DSCR or NOI coverage—not a single percentage of price.

What percent rule should I use instead?

There is no official replacement percent. Some investors talk about 0.7% or a “2% rule” for deep cash-flow markets. Those have the same blind spots. Build a PITIA-and-vacancy sheet.

Can a property fail the 1 percent rule and still qualify for a DSCR loan?

Yes. DSCR cares about rent versus PITIA, not about rent versus purchase price. A more expensive house with modest taxes and a larger down payment can qualify while a cheap, high-tax, high-insurance house that “hits 1%” does not.

Why do so many listings still mention the 1 percent rule?

It is easy to print and it sounds like a standard. It is not a GSE rule or a HUD rule. It is marketing language from an older cycle.

Should I only buy in markets that still meet 1%?

Only if you want to constrain yourself to the leftover stock those markets offer, including capex and tenant-risk you must be willing to operate. Many durable LTR portfolios were built on sub-1% price-to-rent with conservative leverage. Underwrite the business, not the slogan.
