Off-market leads are updated daily, Monday - Friday. New entries are being added to the spreadsheets daily, usually at the bottom. Not every spreadsheet gets new information every day - some areas might not have new filings, or we may not get a new filing entered the first day because of a large number of filings in another area.
Most code violations are updated monthly, but at different times of the month depending on the individual city. Some are updated less often - Houston, for example, only updates their list twice a year.
