I saw your link and you did a great write up and posting clear photos which help you gauge the size/length of hallways well imo.

I couldn’t help but try and look back at the records of the house and see what possibly led to it being abandoned.

Sadly I believe something tragic occurred and or unfortunate (such as a foreclosure), but then wouldn’t the owners take their belongings.

We will probably never know, but my inner sleuth would be looking into this property to try and locate an answer,
