I saw a video of the snakes under the house- it’s either a mobile home or a modular home. Very common around here (Albany is about 30 miles from my town).
Oh we have some really beautiful modular homes out here in CA. places like Acton where they have acreage, I totally forgot about modular homes, Silvercrest makes a gorgeous modular home with massive amounts of square footage they are NOT inexpensive as many would assume!!!
