CHUM stands for "Computerized Homes Underwriting Management." This is the system the FHA uses to automate the mortgage application process from assignment of the case number to endorsement.
The CHUM number, or case number, is assigned to property addresses. Users request a case number in order to identify and follow their mortgage application.
The CHUM system collects personal information from users. This information includes address, social security number, email addresses and other identification data. The data is collected for the purpose of determining the credit-worthiness of potential borrowers.
Case numbers are required to be obtained through electronic means, specifically the CHUM system. Case numbers will be given over the phone only under specific circumstances.
