How to Find the Owner of a Vacant House

To find the owner of a vacant house, start with the property’s street address and look up its parcel in the county assessor or property appraiser’s records. Check the recorded owner and mailing address, then compare the parcel and deed information with the county recorder if you need to confirm what public documents show. DealMachine can help you search the address and review available property and owner details; records and contact matches vary by property.

1. Confirm the property address

Write down the full street address, including the city and state. If you found the house while driving, verify the street number and spelling before searching; a nearby parcel or unit can point to a different owner.

2. Look up the parcel in local public records

Search the county assessor or property appraiser website by address. If the search does not find it, try the county parcel map or search by parcel identification number (APN), if you can get that from the map. Review the parcel address, owner of record, tax mailing address, and last-sale or deed references when shown.

County records are not a guarantee of current title or a person’s identity. A tax mailing address different from the property address can be a useful clue, but it does not prove the home is vacant, that the owner wants to sell, or that the listed person is the only person with an interest. For recorded deeds and other filings, use the county recorder or clerk and check the document date. For legal questions about title, consult a qualified local professional.

3. Search the address in DealMachine

Search the verified property address using DealMachine's supported property-search workflow and compare the matching result with the county record. AI Search turns plain-language descriptions into property filters; current guidance does not describe it as a direct address lookup. Do not treat a nearby result as an exact match.

If the address is not an exact match, use the county parcel number or map to identify the right parcel, then search the verified address again. Do not assume a nearby result is the same property.

4. Review available owner contact details

When the property result includes owner contact information, review it against the recorded owner name and mailing address. A contact match is a lead to verify, not proof that a phone number or email is current or belongs to the recorded owner. If no contact details appear, use the county’s public-record process or another appropriate, lawful source; do not treat missing data as evidence that no owner can be found.

Worked example

Suppose you find a vacant-looking house at 123 Oak Street in Sampletown. You confirm the street number on the parcel map, then search the county assessor’s site for 123 Oak Street. The county record identifies a parcel and an owner of record, with a tax mailing address elsewhere. You search the verified address in DealMachine and compare the result’s address and parcel details with the county record. If owner contact details are shown, you treat them as unconfirmed leads and verify before relying on them. The different mailing address may suggest the owner receives mail elsewhere, but it does not prove vacancy or motivation to sell.

What does it cost?

Browsing and searching are free. The published data-credit guide says revealing owner phone numbers or emails, exporting chargeable details, and enriching records can use credits; included amounts depend on your plan. Check the current pricing page and the in-app cost estimate before requesting chargeable data. See Understanding Data Credits for details.

Can I use an AI agent?

DealMachine also offers an MCP server for connecting compatible AI agents. See the MCP server and its setup instructions to connect it to your agent. You can also create a DealMachine account to search properties yourself.

Common questions

Can I find the owner from the address alone?

Often you can begin with an address, but the county’s search options and the records available vary. If an address search fails, try the parcel map or parcel number.

Does an out-of-area mailing address prove the property is vacant?

No. It only shows where tax mail may be sent. Verify occupancy separately and do not infer that an owner wants to sell.

Will DealMachine always show a phone number or email?

No. Available property and contact information varies. Treat contact matches as unverified until you confirm them.

What if a company or LLC owns the property?

County records may identify a company as owner. State business filings may provide information about that entity, but they may not identify the individual behind it. Disclosure varies, so do not assume a filing reveals the actual person who controls or benefits from the company.
