Reader question: “I’m hoping you can settle an argument for me. I was pre-approved for a mortgage loan about 10 days ago, and we are now starting to look at houses for sale. My husband said we have to be careful what we do with our finances because we can still be denied for the loan, even though we’ve already been pre-approved by the lender. Is this true? I thought the difference between pre-qualification and pre-approval was that the latter was more set in stone.”
