This has been an awesome read.
I am in a similar situation with little in the way of resources/cash and with debt I am trying to get rid of.
Gives me hope that my plans at least have a chance of working.
In the area I live in there is a ton of land available.
Some of it easily attainable (5-10 acre lots @$250 down/$250 month) but you are paying a premium per acre (nearly $10k/acre).
There are other plots of varying size that come up for sale at better prices but not always a owner financed situation which is what we need.
My goal, for whatever land we buy, will be to have it paid off within a 5-6 year period.
So still looking, praying and hoping.
