Where to Buy Homeowner Data and Filter It by ZIP Code

If you sell anything to homeowners — roofs, solar, HVAC, windows, insurance, mortgages, or a listing presentation — you have two ways to get in front of them. You can rent attention from a lead marketplace at $50 to $400 a pop, shared with three competitors who got the same phone number you did. Or you can buy the underlying homeowner data once, own it, and market to it on your own schedule.

This guide covers the second path: where homeowner data comes from, which fields are worth paying attention to, how to filter it down to the ZIPs you actually service, and what the math looks like next to per-lead pricing.

Where homeowner data comes from

Almost every homeowner file in the United States traces back to the same raw material: public records.

• County assessor rolls. Every county assesses property for tax purposes. Those rolls carry the owner of record, the mailing address, the situs (property) address, lot and building characteristics, and assessed value.
• Recorder and deed filings. When a property changes hands, the deed is recorded. That is where purchase date and sale price come from.
• USPS address data. Used to standardize and validate deliverable addresses.
• Commercial compilers. Aggregators pull all of the above across thousands of counties, match it, de-duplicate it, and sell access.

That is the honest version. Nobody is handing you a secret file. The difference between vendors is coverage, how current the file is, how cleanly it is matched, how it is filtered, and what you pay per record.

You will generally see four kinds of sellers:

1. Lead marketplaces. They generate a form fill or inbound call and resell it, often to several contractors at once. Highest cost per contact, fastest intent.
2. Enterprise data providers. Deep files, strong filters, annual contracts and seat minimums. Great if you have a data team.
3. List brokers. They source from the same compilers and mark it up. Fine, but you are paying for a middleman and often renting the list for one use.
4. Self-serve data platforms. You pick your filters, see the count, pay for what you select, and download a CSV you own. That is the lane US Data Connect operates in.

What is actually in a homeowner record — and which fields matter

A bloated file with forty columns is not better than a tight file with eight columns you will actually use. Here is how to think about it.

Fields that drive revenue

• Owner name. You need it for personalized mail and for sounding like a human on the phone.
• Property address and ZIP. Your routing, your service area, your mail drop.
• Owner-occupied flag. Renters do not buy roofs. This single filter removes a large share of wasted spend for home services.
• Purchase date / ownership recency. New owners spend. Someone three years into a house is thinking about the kitchen, the HVAC system they inherited, and the roof the inspector flagged.
• Property type. Single-family detached is the buying unit for most of the trades. Condos and multi-unit buildings have different decision makers.
• Square footage. A rough proxy for system size, job size, and ticket value.

Fields that sound useful and usually are not

• Assessed value, which lags the market badly in many counties.
• Estimated income models, which are modeled at the block level rather than observed.
• Long lists of demographic appends that make a file look impressive and rarely change who you call.

US Data Connect's inventory is built around the fields above: single-family, owner-occupied homes, generally purchased in the last 0 to 5 years, 1,000+ square feet. That is a deliberately narrow definition. It leaves out rentals, tiny parcels, and owners who bought a decade ago and have already been marketed to a hundred times.

Filtering by state and ZIP without over-filtering

The most common mistake is slicing the file so thin that nothing is left. The second most common is buying a whole state when you only service nine ZIPs.

A workable sequence:

1. Start with the state. Current US Data Connect inventory includes 5,616,052 homeowner records available across 50 states, with coverage concentrated in some markets more than others — 1,978,934 homeowner records available in Washington, 1,801,076 in California, 801,463 in Oregon, 581,119 in Texas, 179,583 in Florida, and 120,309 in Pennsylvania.
2. Add your ZIPs. Pull your last 50 closed jobs and list the ZIPs they came from. Those are your core. Add the ring of ZIPs you would happily drive to.
3. Check the count before you buy. If your ZIP set returns a few hundred records, widen the radius. If it returns 40,000, you have a sequencing problem, not a data problem — buy it and work it in waves.
4. Split by recency if you need to prioritize. Newest owners first is a reasonable default for home improvement, insurance, and real estate follow-up.

One practical note: a ZIP code is a postal routing unit, not a neighborhood. Some ZIPs straddle very different housing stock. If a ZIP underperforms, look at whether you are hitting two different markets with one message before you blame the data.

The cost comparison that matters

Industry estimates put shared home-improvement and solar leads anywhere from the low tens of dollars to several hundred for exclusive appointments, and many marketplaces charge in that range regardless of whether the homeowner ever answers. Compare that with buying the underlying records.

	Shared marketplace lead	Exclusive marketplace lead	Owned homeowner list
Typical cost per contact	Industry estimates suggest roughly $50–$150	Industry estimates suggest roughly $150–$400	$0.009 per record on the $59/mo Premium plan
Exclusivity	Sold to multiple contractors	Exclusive for that one lead	You own the file outright
Reuse	One lead, one shot	One lead, one shot	Mail, call, text, retarget, re-contact
Who controls the message	The marketplace	The marketplace	You
Who owns the relationship	The marketplace	Shared	You
Intent at first touch	Higher	Higher	Lower — you create the demand
Volume control	Whatever they send you	Whatever they send you	Every matching homeowner in your ZIPs

At $0.009 per record, 5,000 homeowners in your service area costs $45 in data. That is less than the price of a single shared lead in most verticals. The trade is real and worth stating plainly: marketplace leads come with intent attached, and a cold list does not. You are buying reach and ownership, and you supply the offer, the creative, and the follow-up.

What tips the math is reuse. A marketplace lead is consumed the moment you call it. A list you own can be mailed in March, called in April, and mailed again in September. The cost per record does not change; the cost per conversation drops every time you touch it.

Compliance: what to do before you dial

Be clear-eyed about what this data is. These are homeowner and property records compiled from public and commercial sources. They are not opt-in marketing lists, they carry no consent, and nobody asked to hear from you.

Practical housekeeping before you run a campaign:

• Scrub against the National Do Not Call Registry and any applicable state registries before calling. Maintain your own internal do-not-call list and honor it immediately.
• Understand TCPA rules for automated dialing and text messaging. Texting cold records carries meaningfully more risk than mailing them, and the rules change. Get your own legal read on your specific program.
• Direct mail is the low-friction entry point. Mail does not require consent in the way calls and texts do, and a well-targeted postcard into a tight ZIP set is a clean first touch.
• Identify yourself honestly on every channel and make opting out easy.

None of this is legal advice. It is standard operating hygiene, and it is the difference between a durable outbound program and a problem.

How different buyers use the same file

• Roofers and storm restoration. Pull ZIPs in the hail or wind footprint, mail within days, door-knock the same list.
• Solar and HVAC. Filter for recent purchase and larger square footage, then sequence mail plus a call campaign on the scrubbed subset.
• Insurance agents. New owners are rate-shopping. Recency is your best filter.
• Real estate agents and investors. Ownership tenure and neighborhood-level saturation mailing still work; see Real Estate Seller Leads: Source Them From Property Data.
• Loan officers. Purchase date tells you who may be approaching a refinance or HELOC conversation — more on that in Mortgage Leads for Loan Officers: Own the Homeowner Data.

Closing

Buying homeowner data is not complicated once you stop shopping for magic. The records come from public sources, the fields that matter are few, and the real leverage is in filtering tightly to the ZIPs you service and then working that list more than once.

Start narrow, test a message, measure response by ZIP, and expand into the ZIPs that paid. When you are ready to see counts for your area, build your list and pull a CSV you own.
