How 1% Rule Is Calculated

1% Rule = Monthly Rent ÷ Purchase Price × 100

The 1% rule is the fastest screen in single-family rental investing: monthly rent should be at least 1% of the purchase price. A $200,000 house should rent for at least $2,000/month. If it does, the deal is worth a deeper underwrite. If it doesn\'t, move on — or you\'re buying for appreciation, not cash flow.

It\'s a screen, not a standard. A deal that hits 1.1% might still cash flow poorly after high taxes, insurance, and maintenance. A deal at 0.8% in a rapidly appreciating market might be the right buy. The 1% rule\'s value is that it kills obviously bad deals in 5 seconds so you can spend your time on the ones worth analyzing.

The 2% rule is the same idea, stricter. It\'s realistic in low-cost midwest markets (Cleveland, Detroit, Memphis) where $80k houses can rent for $1,200. In coastal or tier-1 markets, 1% is rare and 2% is nearly impossible.

In 2026, typical rent-to-price by market:

  • Low-cost midwest/south: 1.0–1.5%+ achievable
  • Growing secondary metros: 0.7–1.0%
  • Tier-1 coastal: 0.4–0.6%
  • Luxury / trophy: 0.3–0.5%

Worked Example

Inputs
Purchase $200,000 · Monthly Rent $2,100
Calculation
$2,100 ÷ $200,000 × 100 = 1.05%
Result
1.05% — passes the 1% rule. Run a full underwrite to confirm cash flow.

1% Rule FAQ

What is the 1% rule in real estate?

The 1% rule says monthly rent should be at least 1% of the total purchase price. A $200,000 rental needs $2,000/month in rent to pass. It is a quick screen, not a full underwriting standard.

Is the 1% rule still valid in 2026?

In expensive markets (coastal, tier-1 metros) the 1% rule rarely hits — 0.5–0.7% is common. In midwest and southeast secondary markets, 1%+ is still achievable, especially on value-add deals. Use it as a screen, not a pass/fail gate.

What's the 2% rule?

Same math, stricter threshold — monthly rent at least 2% of purchase. Realistic only in low-cost markets (Cleveland, Detroit, Memphis). Hitting 2% usually signals either a very low-priced market or a deal with heavy tenant/management risk.

What rule do I use if the 1% rule doesn't apply to my market?

Use DSCR or cash-on-cash instead. Target DSCR of 1.20×+ on your financing and cash-on-cash of 8–12%. The 1% rule is a shortcut for these; when it doesn't work, just compute the underlying metric directly.
