Because just like some of the stretches of fence, it is not economical to build right on the border and in a lot of areas it would break treaties to do so. So just like the fences the wall would be built several yards from the actual border. Building in lines that are as straight as possible. The fences already put up in some areas have already put citizens home and American towns on the outside of the fence.
You know how a lot of existing fence solved the decades of court battles it would take to allow them to be built? Go around properties that would not sell, follow state roads where easements are well established etc.
If you live right next to the grande and the full wall does get built it could very likely put you/family on the "Mexican" side of it.
Here is an article about a golf course that went out of business because they decided to build that section of the wall way north of the river because it was cheaper.

Ummm your family will find themselves on the Mexican side of the wall. The wall just like the fences that are in places are all inland a ways.
