How investors find owner phone numbers, emails and mailing addresses — how it works, what it costs, whether it’s legal, and when you actually need it.
Skip tracing in real estate is the process of finding a property owner’s current phone number, email and mailing address by matching public records and other data sources against the owner’s name and property address. Investors and wholesalers use it to contact owners who are otherwise hard to reach — absentee landlords, heirs to inherited houses, owners of vacant properties — so they can make an offer before the property ever hits the market.
In this guide:
Skip tracing is the practice of locating a person — and their current contact information — when the information you have on file is missing, outdated or incomplete. In real estate, the starting point is almost always a property. You know the address and, from the county record, the owner’s name. What you usually don’t know is how to actually talk to that owner: their cell number, their email, or where they live if it isn’t the property itself.
A skip trace fills in those blanks. You (or a data provider) take the owner’s name and the property address, run them against large identity databases, and get back the contact details that match. The output of a good trace is a set of phone numbers ranked by confidence, one or more email addresses, and the owner’s current mailing address — which matters a lot for absentee owners, whose mailing address is different from the property address by definition.
Skip tracing has been used for decades by debt collectors, private investigators, process servers and repossession agents. Real estate investors adopted the same techniques because they face the same problem: the person they need to reach doesn’t want to be found, has moved, or simply has no public phone listing. The difference is intent — investors aren’t collecting a debt, they’re trying to open a conversation about buying a property.
The name sounds technical, but its origin is plain English. Someone who left town to avoid debts or obligations was said to have “skipped town.” The person was the skip, and the work of tracking them down was tracing the skip — hence, skip tracing. The professionals who did this work, long before databases existed, were called skip tracers, and they worked from phone books, city directories, courthouse records and interviews with neighbors and relatives.
Modern skip tracing is the same job with better tools. Instead of driving to the courthouse, a skip tracer — or an investor with a $20 budget — queries aggregated databases that already link billions of records: names to addresses, addresses to phone numbers, phone numbers to relatives. What took a professional days in 1980 now takes a batch upload and a few minutes. That collapse in cost and effort is why skip tracing went from a specialist trade to a routine step in nearly every real estate investor’s workflow.
Every skip trace is a matching problem: connect the identity on a property record to the freshest contact data available for that same person. The inputs are simple — owner name, property address, and sometimes a mailing address from the assessor file. The provider then matches those inputs against several categories of data:
The provider’s matching engine weighs all of these, resolves conflicts (two people with the same name, an owner who moved twice in three years) and returns the best candidates. A typical result for one property looks like: two or three phone numbers with type flags (mobile vs landline) and confidence scores, one or two emails, the owner’s current mailing address, and sometimes ages and relatives to help you confirm you’ve found the right person.
Quality varies with the freshness of the underlying data. A provider that re-verifies numbers against live telecom activity will cost more per record than one reselling a stale aggregate file — and the difference shows up immediately in how many of your calls connect to the actual owner.
Investors skip trace because the best off-market opportunities belong to owners you can’t reach any other way. The lists investors pull — covered in depth in our guide to how to find motivated sellers — are full of owners whose situations make direct contact both harder and more worthwhile:
Across all of these, the pattern is the same: the county record tells you the property has potential, and skip tracing turns that record into someone you can actually call or text. Whether you should call is a separate question — we cover the legal side and the direct mail alternative below.
Here is the workflow most investors follow when they trace a list of properties:
The honest caveat: steps 5 and 6 are where most of the labor lives. Buying the data is the cheap, fast part. Dialing hundreds of numbers, eating hang-ups and wrong numbers, and staying compliant is the expensive part — which is why the skip tracing vs direct mail comparison below matters.
Skip tracing providers advertise match rates, and the numbers deserve context. A match rate is the share of records the provider returns any data for — typically 70–90% on a reasonably clean residential list. That is not the same as accuracy. A “match” can be a disconnected landline or a number that now belongs to someone else; what you actually care about is the right-party contact rate: how often a call reaches the true owner.
Three realities to plan around:
The practical takeaway: treat 70–90% as the ceiling for getting data back, assume a meaningfully lower share of that data connects you to the right person on the first attempt, and buy the tier that matches how much your time on the phone is worth.
Skip tracing is priced per record, and the spread is wide:
The sticker price is only part of the cost. Add the hours spent cleaning lists, dialing wrong numbers and logging attempts, plus dialer software and compliance scrubbing if you’re calling at volume. When investors compare channels honestly, the fully loaded cost of a cold-calling operation often surprises them — which is worth keeping in mind before you buy data for thousands of records. For a sense of how Farmrix prices the alternative, see pricing; plans start at $97/mo.
Yes — skip tracing itself is legal in the United States when used for legitimate purposes, and contacting a property owner to make an offer is a legitimate purpose. The industry operates inside a framework of federal law:
Two rules of thumb keep you safe. First, buy data only from established providers who source it lawfully — if a vendor won’t say where their data comes from, walk away. Second, remember that the regulatory risk lives almost entirely in the outreach, not the trace: mailing an owner a letter or postcard carries none of the DNC/TCPA exposure that calling and texting do. This guide is general information, not legal advice; if you’re building a calling or texting operation at scale, spend an hour with an attorney first.
Here’s the part of the skip tracing conversation most guides skip: you don’t need skip tracing to send direct mail. The owner’s mailing address is already sitting on the county assessor record — it’s public, it’s free, and for absentee owners it already points to where the owner actually lives, not the rental they own. Skip tracing exists to get you phone numbers and emails. If your outreach channel is mail, the trace is an unnecessary expense.
So the real question isn’t “how do I skip trace?” — it’s “which channel do I want to work?”
Many successful investors run mail as the primary channel and reserve skip tracing for the narrow cases where it clearly earns its keep: a vacant property whose owner’s mailing address bounces, a probate case where the heir needs to be located, or a high-value target worth a personal phone call. That’s a few dozen traces a year, not a few thousand.
Farmrix is built around the direct mail side of this equation. Instead of buying a list, tracing it and dialing for weeks, Farmrix finds the owners in your market most likely to sell and reaches them with mail automatically:
If your goal is off-market deals rather than phone-bank hours, that pipeline — score the market, mail the best owners, answer the phone when sellers call you — replaces the entire trace-and-dial workflow. Plans start at $97/mo; see pricing for details, or get started and see your market scored.
The data points a trace appends to each property record.
Mobile and landline candidates, flagged by type and ranked by confidence.
Appended from consumer files, useful as a secondary touchpoint.
The owner’s current home — key for absentee owners and heirs.
Age, relatives and previous addresses to confirm the right person.
