A true preapproval is based on a LO receiving and reviewing your w2s, pay stubs, bank statements, credit report, driver licenese and social security #. Upon doing so, with me at least, you can be preapproved in a little as 5 minutes or up to 24 hrs. This may be true for most other lenders as well.
So there may be a very valid reason for the delay in getting a pre-approval.
What is not acceptable,however, is an "I don't know" answer. If it's going to take a few days, then your lender should clearly explain that to you and clearly explain the process and how it works. If your lender is just too busy to handle your needs and that is what is causing the delay then I suggest you contact another lender.
Best of luck to you
