Love the 'crappy bird houses'! If I could offer a few suggestions...
Please, NO exterior perches, these allow predators easy access; please ensure there is ventilation along roof sides.
Please ensure the 'floor' has drainage in all four corners (nipping tiny triangles off before inserting the bottom is ideal).
Please ensure it is easy to clean out (otherwise it just won't happen): installing front panel between side panels with screws then drill a downward sloping hole from side panel into front panel, slip in a nail and you have pegged the front closed with a nail.
Installed houses filled with several inches of wood chips makes them very appealing to house hunters!

I made a crappy birdhouse today! I used cedar boards from a deck I salvaged. The back opens up for cleaning.
