We are looking at a new (to us) house that is more of a ranch than a split
level. The Wife says we may need an intercom so we can call out to each
other instead of screaming.

You can always carry cellphone and just call each other.

I have a Radio Shack that just plugs into a receptacle and needs no wiring.
Works well enough for our use to a detached garage. Should work in your
setup also.
