Locate the county name for that city...by going to the city's website for instance. Then go to that particular county's appraisal district website and look up by address. Once you locate the owner's name, you can go to whitepages.com and lookup owner phone number.
In Texas we search by county, in mine it is BCAD.org. First find the county, then do a tax records search. If you have difficulty with that, then call a Title company or a local realtor. I have one I can refer if you want. She's top banana in Phoenix!
