Nathan's house in Vernon, Vermont sold in February for $152,000. The listing includes 36 photos.
I don't think the house has been occupied since Nathan was arrested. I doubt it was rented in the condition it's in, and it doesn't look like a squatter lived there. But there are some personal belongings in the real estate photos, including an unmade bed, a few pieces of furniture, and some toiletries. Nathan's estate may have been in probate all this time, which could have restricted access to the house. Or maybe Nathan's father or other relatives didn't want anything in the house.
Nathan bought the house for 70K in 2014. Nathan was renovating it. He added 2 stories. He put the house on the market for $149,000 in March 2018. The listing was removed and relisted a few times in the following months. It was listed at $80000 when it was taken off the market in October 2018.
