How can I find every property owned by the same person, LLC, or company?

Every later match gets compared with this first property, so record it carefully. Copy the owner's name exactly as the deed writes it, punctuation included. Add the APN, the county, the deed's recording date and document number, and the mailing address on the tax bill.

Then open a spreadsheet and give each candidate parcel its own row. For each one, note the search that found it, the owner name as written, the latest transfer with its document number, and the outcome. That record lets you say later which searches you ran and which document settled each parcel.

The name search is the broadest one. PropertyRadar's lookup takes a city, county or ZIP and then a person's or company's name. Its owner portfolio view lists the properties tied to a person, LLC or company across a market or nationwide, drawing on records normalized across more than 3,000 counties. One search there covers counties you would otherwise query one at a time.

Run the name more than once. PropertyRadar's criteria glossary defines Owner Name as each person or entity extracted as an owner from assessor or recorder documents, so the field carries whatever spelling each deed used. Try LLC and L.L.C., with and without the comma. For a person, try the name with and without a middle initial, and paired with a spouse.

The mailing address finds what the name search misses. San Bernardino County's assessor, for example, takes the owner's mailing address from the change-of-ownership report the buyer signs at recording, and keeps it until the owner files a change. An investor who buys ten houses through one office gives the county the same address ten times, whatever name is on each deed. So a search on that address surfaces parcels held under names you haven't tried.

The address search also returns parcels that have nothing to do with your owner. A property manager or an accountant can receive tax bills for many unrelated clients, and all of those parcels share the address. And a parcel still billed to an address the owner used years ago won't appear at all.

An LLC's formation filing can give you more names to search. Texas requires the certificate of formation to name each initial manager, or each initial member when there are no managers, with an address. Add each of those people to your search list, along with any company named as a governing person. Delaware asks for less. Its certificate of formation has to state only the company's name and its registered office and agent, so a Delaware filing can add no names at all.

A shared registered agent doesn't connect two companies. It shows only that both receive legal papers through the same agent. Keep an agent's name when it also appears among the governing persons or on a recorded signature. Reaching the person who can negotiate is a separate job, covered in finding the decision-maker behind an LLC or trust.

Each new name, company and address then gets its own name search and address search. Keep going until a full pass turns up nothing new.

Suppose the known parcel is a Harris County fourplex owned by a Texas LLC. The tax bill goes to a Houston office suite, and the certificate of formation names one manager. Your searches return parcels in three counties.

Some of them resolve quickly. A duplex in Harris County carries the exact name and the same suite. Its latest deed names the LLC as grantee, and the index shows no later deed out, so it goes on the list as confirmed as of that search date. A house in Fort Bend County shows the name with L.L.C. and a comma, at an older mailing address. The deed describes the grantee as a Texas limited liability company, and the Secretary of State's search returns one entity for both spellings. That is the same owner, and the older address becomes a new search key. A triplex shows the exact name too, but the index holds a 2023 deed to another buyer. The LLC sold it, so it comes off the list.

Two results are harder, and they show the two kinds of collision. The first is a house billed to the same suite and owned by a different LLC. Its filing names a different manager, and the suite turns out to belong to a property management firm. Only the address ties it to your owner, so it stays a lead. Even a shared manager or loan signer would leave it a related lead, because the deed names a different company. The second is a lot held under the identical name, where the deed describes the grantee as a Delaware limited liability company. The state of formation is what separates companies here. A company formed in Delaware is a different legal entity from one formed in Texas, even when the names match. A Texas LLC that has registered to do business in another state is still the same Texas company, so read which state formed the grantee before deciding. The same person may be behind both companies, and the name alone can't show that. The lot stays unresolved until you check Delaware's records. After that it is a related lead, unless a recorded correction shows the deed meant the Texas company.

A different mailing address, by contrast, is no reason to reject a match. Owners change addresses between purchases.

The last row of that table matters when an investor holds each property in its own company. Suppose one more result is a fourplex owned by a second Texas LLC whose filing names the same manager. That fourplex has a different legal owner, so it stays off the list of what the first LLC holds. If you are tracing everything connected to that manager, it starts a second list of related leads. The filings support one fact about that list: the same person was named manager of both companies at formation. Who manages either company now, and who owns them, are questions the formation filing leaves open.

Platform data tells you which document to pull. PropertyRadar's glossary defines Buyer Name as the grantee, the party receiving title, and Seller Name as the grantor. Each transfer carries a date and a document number, and the Most Recent Change of Ownership criterion isolates the latest ownership transfer on a parcel. Check that the grantee on that transfer is your owner, and note the date you looked.

Then look for a deed out. The deed that put an owner in title can't show whether they have since sold, so search the county's grantor index under the owner's name. The Harris County Clerk's real property search takes a grantor or grantee name and returns documents recorded with that clerk. Each neighboring county is its own search, with its own name variants.

An online index can trail the recorder's office. Harris County says a document can take one to two business days to appear after processing, and that the online database is not the official repository. For a parcel that decides a deal, order the recorded deed and rerun the grantor search shortly before you make the offer. An index with no deed out shows what had been recorded and indexed when you searched. Current title is a question for a title search on that parcel, which any purchase still calls for.

The search is finished when every name, alias, address and related entity has been run in every county in scope, and the last full pass added nothing. Each row should carry one of four outcomes: confirmed, related lead, rejected or unresolved. A row stays unresolved while a county index, an older deed or a layer of entities is still unsearched.

Report the result with its boundaries. State the names, addresses, entities and counties you searched, the date of the latest records you read, and the count in each outcome. A property held in a company that shares no name, address or filed person with your starting parcel gives these searches nothing to match, so it won't be on the list.

PropertyRadar offers one cross-check. Its glossary describes Number of Properties Owned as an estimated count. Compare it with your confirmed total. Because the count is an estimate, a difference is a reason to recheck the rejected and unresolved rows, and it doesn't mean the sheet is wrong.

Owners keep buying after the list is built. PropertyRadar lets you save a lookup as a dynamic list and turn on monitoring, which updates the list automatically. An unmonitored dynamic list refreshes only when you open it. A new match on the monitored list enters the sheet as a candidate and gets the same county check as the rest.
