Door knocking prospecting: build the list, plan the route, know the rules

Who door knocking works for

Door knocking works for sellers whose prospect is a home, and whose offer is easier to judge in person. The common users are real estate agents farming a neighborhood, roofers after a storm, solar sellers, pest control and lawn companies, and other door-to-door (D2D) teams. It suits a small, dense area where the same person can return more than once.

It is a poor fit when the buyer is a business, when homes are far apart, or when the offer needs paperwork before a conversation. For those, start with direct mail prospecting or cold calling. This guide sits in the how-to hub.

Seller	Trigger	List filter that matters
Agent farming	Steady presence, listings nearby	Owner-occupied, long tenure
Roofer	Hail or wind path, home age	Owner-occupied, older homes inside the storm path
Solar	Utility area, roof fit	Single family, owner-occupied
Pest and lawn	Season, route density	Single family, clustered on one street

Build the route from a property list

Start with a list, then cut it down to a route. A homeowner list from county assessor records gives every owner and the property type. Cut it in this order:

1. Keep owner-occupied homes. Drop absentee owners, because the person who owns the home does not live there.
2. Keep the property type you sell to, usually single family.
3. Filter on home age or tenure. Roofers want older homes. Agents often want long ownership, and a high equity homeowner list is one way to find owners who can act.
4. For storm work, clip the list to the storm path using the weather service's event map.
5. Sort by street and number so each block is one walking run.

Cap each route at the number of homes you can finish in one outing. HousingWire's planning guidance is about 30 houses per outing. Counts by state are on the homeowner counts page, and the absentee counts page shows what you remove.

Hours, permits and no-knock rules

There is no federal permit for knocking. Cities and counties set the rules, so read the municipal code for each town on your route. Four things recur: a solicitor permit, daytime-only hours, a no-knock registry or sticker program, and a posted No Soliciting sign that you must honor.

The Supreme Court limited how far towns can go. In Watchtower Bible v. Village of Stratton (06/17/2002) it struck a permit rule for door-to-door advocacy and noted that residents can post a No Solicitation sign and refuse to talk. The case concerned advocacy, not sales. Commercial sellers should assume a permit is required until the town says otherwise. The door to door sales laws page has the state cancellation table and permit detail; the compliance hub collects the other outreach rules.

Never place a flyer in a mailbox. 18 U.S.C. 1725 fines anyone who puts unstamped mailable matter in a Postal Service approved mailbox to avoid postage. Use the door handle and leave the box alone.

What it costs

The costs are your time, the leave-behinds and the miles. The IRS business standard mileage rate is 76 cents per mile for 07/01/2026 to 12/31/2026. Time is the largest line, and the wage you assign to it is your own input.

Cost line	How to count it	Worked example
Mileage	Miles driven x $0.76	20 miles x $0.76 = $15.20
Time	Hours x your hourly value	3 hours x $25 (assumed) = $75.00
Leave-behinds	Pieces x your print cost	30 x $0.30 (assumed) = $9.00
Permit	Whatever the city charges	Look up per town
Total for the outing	Sum of lines	$99.20 plus any permit

At HousingWire's 2 to 3 conversions per 100 doors, 30 doors yields 0.6 to 0.9 conversions. The example outing at $99.20 then costs about $110 to $165 per conversion. Replace every assumed input with your own and rerun the arithmetic.

What the numbers look like

Published door knocking figures are thin. The one figure HousingWire gives is that 2 to 3 of every 100 houses convert, and the article does not define "convert" and links to a software vendor's blog rather than a study. Treat every band below as a starting guess until your own routes replace it.

Measure	Band	Source and status
Time per house	About 15 minutes planned, about 4 doors per hour	HousingWire author guidance, not a study
Conversion	2 to 3 per 100 doors	HousingWire, unnamed upstream source, anecdotal
Conversations per hour	No sourced figure	Measure it on your routes
Appointments per 100 doors	No sourced figure	Measure it on your routes

What good looks like on a route you run yourself:

Metric	How to measure	Use
Doors per hour	Doors approached / hours on route	Check route length
Conversation rate	Conversations / doors approached	Check script and timing
Appointment rate	Appointments / conversations	Check the offer
Cost per appointment	Outing cost / appointments	Compare with mail and phone

Log each outing for two weeks. The median of your own routes is the benchmark.

The sequence: knock, leave-behind, follow-up

One knock rarely closes. Pair the visit with a leave-behind and a second touch.

• Day 0Knock. Short script: who you are, one fact about the street, one ask. Leave a door hanger if no one answers.
• Day 2Postcard to the same address with the same name and offer.
• Day 7Second knock on homes that did not answer, at a different hour.
• Day 14Follow-up call or text only where the person gave a number and consent. See [SMS text prospecting](/how-to/sms-text-prospecting/).
• Day 30Second postcard or market note. The [multi-channel sequence](/how-to/multi-channel-prospecting-sequence/) page shows how to space it.

A short real estate script: "Hi, I'm [name] with [brokerage]. I work on this street and wanted to share what two homes nearby sold for. Can I leave it with you?" Then stop talking and listen.

Compliance notes

• Cooling-Off Rule. Under 16 CFR 429.0 and 429.1, a sale made in person at the buyer's home for $25 or more carries a three business day right to cancel. The seller must give a dated receipt, a notice and two cancellation forms in the language of the pitch. After a cancellation the seller refunds within 10 business days. The rule excludes real estate, insurance and some securities sales, and it excludes sales made entirely by mail or phone. A buyer-requested repair visit is also excluded, unless you sell more than the repair needs.
• Permits and hours. Check each municipal code. Keep to daylight hours unless the code says otherwise.
• Signs. A No Soliciting sign ends the visit. Do not argue and do not return.
• Licensed agents. State real estate advertising rules apply, and your brokerage name usually must appear on leave-behinds.
• Records. Keep a do-not-return list from each outing.

This page is not legal advice. Confirm the rules for each town before you knock.

Pull counts for the zip codes on your route to see how many owner-occupied homes remain after you remove absentee owners. Ask for counts for your exact area.

Questions people ask

Q01Is door knocking legal?

Yes in most places, with local limits. Cities set permit, hours and no-knock rules, and a posted No Soliciting sign ends the visit. The Supreme Court struck a blanket permit rule for canvassing in Watchtower v. Stratton (06/17/2002), but sales permits still stand in many towns.

Q02What is the Cooling-Off Rule?

It is an FTC rule. When a seller solicits in person and the buyer agrees to buy at home for $25 or more, the seller must give a written notice and two cancellation forms. The buyer may cancel until midnight of the third business day.

Q03Can I leave a flyer in the mailbox?

No. Federal law, 18 U.S.C. 1725, bars putting unstamped mailable matter in a mailbox approved by the Postal Service. Use the door handle, the door itself or a porch, and still honor any No Soliciting sign.

Q04What counts as a good result on a route?

Track conversations per hour and appointments per 100 doors on your own routes for two weeks. Published figures vary and mostly come from coaches, so your own median beats any outside number.

Q05Which homes should I skip?

Skip absentee-owned homes, because the owner does not live there. Skip any address with a No Soliciting sign, any address on a local no-knock list, and any home outside the hours your city allows.
