That much underground would be awful for mold allergies. And IDK how much time and money is needed to deal with nothing ever getting permits

Very unusual unfinished, unpermitted concrete bermed home with unpermitted septic system and no power on 4.97 secluded, wooded acres. Individual well. 4-1,000 in ground propane tanks, 500 gal water storage tank. Used to be powered by a solar system & a generator, both of which were stolen (and other equipment) but electric nearby. Owner was working on a self-sufficient home but passed during construction having spent over $400K on the project. Current best use may be to bring in power, do engineering calculations & permit this structure as a shop/ag building & build another home/manufactured home. Owners have some construction photos. Great buy at the list price. There is still a lot of value there. Located in the country East of Olympia.
