When it comes to property releases, due to the global considerations for commercial use, we and our partners tend to reject images with a focus on single buildings, modern architecture or works of art. This would be when the property is identifiable or identifiable by its location, or when it's the main focus of the image (even if taken on public grounds). With the volume of images, a detailed check of the location/rights/legal situation of every single building usually is not possible.
If you are unable to obtain the property release, then we will not be able to sell the photo under a commercial license. However, you can still show them under an editorial license in EyeEm Community. Here's an article that can help: https://www.eyeem.com/blog/do-you-need-a-legal-photo-release/
