AH! beautiful! Stain would look great, BUT if you are painting (white) I would seriously consider a bold color. Your home would look GREAT with a bold door. Search on house for front door color and you'll see a bunch of bright colored doors. If youre not an orange/red/yellow/lime green door kind of family, you could go with a Navy/dark grey?

id take a quick scan across houzz.. if you are really undecided, the doors are beautiful, so stain is the safe choice. you can always paint but I learned THE HARD WAY : o ) its definitely harder to go from paint back to stain....
