Megan,
The best thing to do is check with your lender. I think what your referring to is for conventional loans (Fannie Mae or Freddie Mac)
The intention of the last minute credit check is to prevent borrowers from buying multiple house on the same day using different lenders.
If your getting an FHA loan then your lender may choose to pull a last min. credit report for similair reasons. The scores change should be marginal
so it should not impact your ability to close your loan. The best thing to do is check with your lender, if your closing tommorrow likely all of this is already
done, The papers should be a the title company or attorney since your closing tommorrow. Worse case is you need to wait a day or two. These rules call
for a "reasonble time" to prove occupancy, so a day or two should not matter.
Thank you,
