A subset of a set of image data is input into a trained convolutional neural network (CNN), the subset of image data including several of digital images, each image including a depiction of a real estate property at a different zoom level. By executing the CNN, a set of features is extracted from the subset of image data, a feature in the set of features being unrepresented in the subset of image data, and where the feature is derived from a depiction in the subset of image data. Using a set of node values configured at a set of nodes in a layer of the CNN, and using the set of features, a combined value of the set of features is computed, relative to the real estate property. A predicted price of the real estate property is predicted, by executing the CNN, using the combined value.
