Lender/Banks Pre-Approval Processes

[Marquis Williams]

Hello everyone!

I'm looking to finally start taking action towards my real estate investing career, while I save enough capital. I see a lot of different topics in regards to pre-approval, but I'm still not sure if I should give any lender my SSN # even though they say they will not run the credit. The lender did not ask, but it is on the application. Should I still give them all my personal information or what main information does a lender need in order to determine pre-approval or not? 

Thank you
