Am sorry, but that house
Is one step up from trailer park trash. Don't meant to offend but just cannot see appliances in that condition and the state of surroundings being "unused".
That house does not look as if they sent things out, and or had another set stashed away somewhere. Presence of a child's bicycle means there are or were children in the household, that means laundry, and lots of it, so where and how was it done?
Even being generous and believing the set was truly "unused" since installation. They've been sat sitting in that environment for so long who knows what the interior looks like, and or has set up housekeeping over the years.
