Systems and methods for detecting image anomalies include extracting one or more detected images from a submission file received from at least one computing device and generating an image identification (ID) for each of the one or more images. One or more image quality indices are determined for the submission file based on at least one of predetermined image features, an image type of the one or more images, and submission file attributes, and one or more image anomalies associated with the one or more images of the submission file are detected based on at least one of the image ID and the one or more image quality indices.

Systems, methods, and computer-readable storage media are described for estimating real estate property values based on an adjusted repeat sales model using a regularized estimator. In one exemplary embodiment, a computer-implemented method calculates data for estimating the adjustments from an aggregated level to a first disaggregated level by marking a first transaction to a second transaction using a repeat sales house price index function at the aggregated level. The method also determines, using the calculated data, a regularized estimate of the deviation between the repeat sales house price index at the aggregated level and a repeat sales house price index at the first disaggregated level. The method further calculates the repeat sales house price index at the first disaggregated level based on the determined regularized estimate of the deviation from the aggregated level.

Systems, methods, and computer-readable media are disclosed for calculating a housing volatility index. An exemplary embodiment includes accessing stored property value data reflecting first values of real estate properties during a first time period and second values of the real estate properties during a second time period. The second time period may be subsequent to the first time period. The property value data may be processed to identify the first values and the second values, and time intervals between dates of the first values and dates of the second values may be calculated. Value changes of the real estate properties over the time intervals may also be calculated, based on the first values and the second values. A volatility measure for the real estate properties may be determined based on the value changes of the real estate properties over the time intervals, and the volatility measure may be output to a user.
