The first rule is usually location. It is hard to find cheap land in a urban area that has already grown tremendously. However this does not mean which you go for a land that has is located in a place without a lot as good road access. All is here taking your time and choosing the best listing with cheap land available that is conveniently located. At the very least, make sure the land you are interested in is at a location which is likely to grow. Also consider the geography of the area, and also the climate. Whether it gets hot or freezing in some seasons, it will not be a worthy purchase, way more if you plan on building in the land.
Second factor to take into consideration is the profitability associated with a cheap farm or hunting land on the market. While land is hardly proven to depreciate, normally it takes time before it comes from any profit. You need to find land in a area which is likely to grow, because growth will probably be associated with a land price increase. Although you may don't want to sell immediately, it really is comforting to learn that you can get good benefit from selling the budget land available that you spend money on.
Stick with proven markets, as opposed to buying some cheap farm land for sale in an area which is hardly known. This doesn't make much sense when you purchase a piece of land outside in the country, in places you know decades will pass prior to the area ever grows. Instead, buy land in a area that already has a spark for growth, before other people seize the opportunity.
When buying cheap land available, keep in mind that the owner will have a sales page ready, and can try to allow you to buy the piece of land. But take the time and look at the buying decision. For those who have any doubts, don't ignore them. Regardless, you can always look someplace else.
