Mostly yes, but what you can put on the land will vary by state/county. It's easy enough to call up a county office ahead of time and tell them what you plan to do. They are usually happy and accommodating to take in new property taxes. Taxes are not too bad if not building a permanent structure. Some counties have rules about things like mobile homes, water tanks, septic requirements and some of them have ways to get around the rules. Some places have next to no rules and are happy to get more people spending money at the local businesses. There isn't really a generic answer to your question. That's how much it varies by location.
