The methodology

What makes a ZIP knockable?

Five metrics, each ranked against every other scoreable ZIP in the country, weighted by how much it moves the needle at the door:

Owner-occupancy30%

Owners answer the door and can say yes. Renters can't buy what you're selling.

Ability to pay25%

High equity, free-and-clear homes, and sale prices in the financeable sweet spot.

Door density20%

Homes per square mile — more doors per hour of walking.

No-HOA share15%

Fewer gates, fewer no-soliciting boards, no exterior-approval headaches.

Aging homes10%

Homes 20+ years old need roofs, systems, and upgrades.

Grades are curved against every scoreable ZIP in the country — an A− means top 10% of America. ZIP-level aggregates only — no individual home data is ever shown. ZIPs with fewer than 500 scoreable single-family homes aren't scored.

The Score rates the ZIP. The app shows the zones inside it.

KnocKnow paints the exact neighborhoods in your ZIP where 70%+ of homes match your perfect customer — so you knock the right streets on day one.
