ideas covering up blank window

[John Ma]

hey guys, I am currently finishing up repairing a few things on a project that will soon be a rental.

There is a blank window that is currently boarded up and I am trying to figure out what to do with it.   The inside is already a closet so it is not visible.   The exterior however is less than attractive and I need a good solution that will not cause any water related damages.

Hopfully you guys can see this once you sign into google.

As you can see, the current siding around the old window is olive-ish aluminum siding.

 I am thinking about having my guy install some siding (most likely wont be a perfect match) where the board is and make sure it is weather sealed with caulking.

Or

Remove the window frame and install siding with caulking, sealing it in.

Does anyone have any inexpensive ideas?

I would install a closed shutter on the window.  We currently have a house we are doing this same thing to where the windows are in a master bath (after we rearrange walls). We are using the same shutters on the other windows but will have them open. To those on the street, it will just look like you have functioning shutters that you have closed.  On the inside, there is no sign of a window.
