can I find online plat maps that show landowners names in a certain county anywhere on the web?
Many of the larger and richer counties do have all of their tax maps available on the internet, but many of the smaller and poorer counties do not. Tax maps show ownership, but in the form of parcel numbers, not names. To learn the name of the owner, you inform the county tax assessor of the parcel number you are interested in, and the assessor will provide you with the name of the property owner.
