The object with the greatest mass.
moon and sun!
House is closest to the earth at its surface, F= mGM/r2.
The one with the greatest mass that is closest to the surface of the Earth.
At the surface, it is 2.64 times its value at the Earth's surface.
About 38% of Earth's gravity.
Objects with the greatest mass will have the greatest force of gravity attracting them to the surface of the earth. Gravitational attraction is based on the mass of an object and the distance between the two "attractors" involved. For things on the Earth's surface, more mass equates to greater gravitational attraction. It's a direct relationship.

The moon's gravity is about 1/6th of the earth's.
The forces of gravity that attract the Earth and an object on its surface toward each other are greatest for the object with the greatest mass. Among the items on your list, that's probably the house.
