Hello there. I am a banker myself. Not on the credit side, but colleagues of mine are just a few offices away. It is absolutely common for the bank to want photos of the property. This is to document the construction progress. Usually, this is done during the construction phase. At the end, photos of the "finished" house. 1-3 photos at the beginning of the construction, then during the construction phase, and at the end after completion are enough. This is just to record in the credit file that a house was really built... consistent with the submitted documents. No one cares about your photos, floor coverings, wall colors, etc. My colleagues also have the customers take these photos themselves and then send or email them. For the credit people, it's just about "checking off" an open point on the "to do" list. None of our people drive out to the customer, no one would have time for that (Note: We are now talking about private buildings in the "normal" price range. So no construction costs over 1.5 million or commercial projects).
However, the colleague also told me: "...have a few nice hours and drive to the customer....." Just ask if it’s enough for you to take the photos and email them.
