We looked into an OWB but ruled against it pretty much out of the gate. Neighbors are too close in our little industrial revolution-era village, now in the middle of nowhere. We heat with a stove that keeps the oil furnace pretty quiet, even on a -5° morning like today. The old wood furnace is still down in the cellar and rehabbing it is a project I'd like to take on, However, some structural work to the chimney would need to be done first.
Not wanting to scare you off, but before you start thinking too much that those 75 acres are $$$ in the bank, please do be aware that NH's tax system is very regressive. With no sales or income taxes, virtually the whole tax burden of funding education falls on local property owners.
If you go ahead with the purchase and move, try to lay some groundwork to put the wooded acres into current use and possibly obtain tree farm status. Both would mitigate some of the sting of your semi-annual property tax bill.
