Check some of the larger, more popular title companies in your area. Determine which ones you think you will want to have a working relationship with. If you're an agent, your broker might already be working with one.
The bigger ones will give you an online account that gives you access to public tax data, from which you can get the farm data you need, and some of them even allow you to print out mailing labels for your farm. You might even have complimentary number of accesses that has a monthly limit, for which you have to pay if you go over.
It's good to get one of these accounts, anyway, because it gives you a lot that you need to know about a property.
Also, check what your local MLS board has to offer. Some MLS give you public tax data access, too.
