If you have a specific camera angle in mind, you could use the grouping tool and save your work and use the delete polygons option to delete enough polygons to put a hole in the wall for you to see into the home. Be careful, this may mess up the UV mapping. Or you can select everything else with the grouping tool and create a prop with it. UV maps are usually okay with this method.

A trans map would be easier, but with this way, you aren't slowing down the render by rendering through a transparency.
