Hi Skyler, welcome to Permies!
What part of the country are you looking at? Narrowing down your search area can really help you figure things out. I did a quick search in one of the cheaper parts of my state and came up with this lot to tempt you with...
5 acres for $6,000 in northern WI
If you don't like snow, it may not be the best fit though. Based on a few searches on Realtor.com it should be pretty doable to get 2-5 acres for under $10K. If I can find them here, I'm sure there are other extremely rural places of the country with them as well. Especially in the countryside where regulations are usually more lax. Do you need to be near a bigger city for a day job? If so, that will clearly limit your "cheap land" options.
I guess I'd start with figuring out what location specific characteristics you need for your homestead, then see what's available for cash or owner financing.
Some things might be:
4 seasons
Need some snow
Need some desert
Need mountains
Near a city of XX population
Distance you'd be willing to commute if you have a job in that city
Take it from there and enjoy the search!
