good luck to you!
if you're thinking of doing this, as one pp suggested, if you have an income already, when you do start looking at properties, etc. it might frighten you depending on where you're moving from if you compare salaries in different areas. consider the cost of living where you're looking first!
for example, i woh while dh is a sahd. i make WAY less doing the same job than i would if we lived elsewhere; however, we have a great piece of property and a large-ish house that would have cost many times what we paid for it because it's so far out.
also, if you are looking, in rural areas, the houses seem to have been for sale for a lot longer.. it's hard to commute, and there are fewer jobs, so you may be able to find something much less expensive.
here's another thing to consider:
we had been saving for a while and had a good bit to put down, and decent credit, etc. we initially found an awesome undeveloped piece of land that i had my heart set on, but the way mortgage lending works made it nearly impossible for us to purchase it. we were much better off finding a property with an existing home... i would advise you to compare interest rates and rules for borrowing on land and building vs. finding a property with existing home. it was eye-opening for me.
otherwise, it's not much different affording where we're living than when we lived in town. we're striving for self sufficiency, and on a tight budget, so saving everything you can will give you a nice cushion for when you do move. bartering is pretty fun out in the sticks, too
