Assessor's Office Records Online
Many assessor's offices are putting their indexes of property ownership records online.
But in many cases you can't find ownership information online because of privacy concerns. Instead you'll only get basic information like the assessed value of a piece of property, and you'll have to go to the assessor's office in person to look up the owner of the property.
One Web site that tracks assessor's offices that have put their indexes online is:
A private real estate research and information company, NETR has a map of the United States on its home page you can click on to bring up a list of all the county agencies in a particular state that handle property sales and ownership. These include assessor's offices.
Agencies that have web pages are noted, and, if an index of their records is available online, that is flagged with a Go to Data Online link.
