Fallout 3 locations project
As with all houses in Tranquility Lane, it has 2 stories with the front door entering into the lounge. The other ground level rooms are a bathroom and a kitchen. Upstairs, the house has another bathroom, and 2 bedrooms; Timmy's containing a single bed, and George and Pat's with a double. A military school brochure can be found here.
Timmy runs a lemonade stand out the front.
The Neusbaum residence contains one special item that can be interacted with to complete Betty's tasks, namely the military school brochure.
If you make Timmy cry during the quest, he will disappear and be replaced with a gnome on the Neusbaum's porch.
The Neusbaum residence appears only in Fallout 3.
