It's called a "trigger lead". A trigger lead is generated every time a credit report is run. As soon as the credit report is run by Equifax, TransUnion, and Experian, it "trigger" their lead system and they, just about instantaneously, SELL your information. It is a shady business practice but it's completely legal. To opt out of these trigger leads you can go to https://www.optoutprescreen.com/ Nothing is wrong with Quicken Loans, they seem to be a decent company... however the bottom line is you must compare your options, do not go for the first lender who offers you a loan, get good faith estimates from 3-4 different sources, and have thougrough conversations with each, before committing to one.
