Can you provide more details on this? By "little cottage", I assume this was meant for one (you), and $130K might be a bit steep for a single-person, experimental venture. 10 AC is hardly a small area, though, and suggests potential to expand it to, say, a 3-10 person number. If the marginal costs required to increase water, electricity, etc, to support such levels don't add to the final price tag dramatically, it could be quite interesting.
