So:Am I right in guessing that if I sell her my stake in the house and take my name off the deed, but I leave the mortgage alone (with both our names on it), my credit score would plummet?

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Right now, rates are below 7% in most cases with very low origination.
