It’s unlikely. Initial qualification without a full credit check may be possible with some lenders; at that point, they may be interested simply in whether you have both the income to pay back a mortgage and no credit red flags. However, to get full-scale pre-approval will likely require a credit check. It’s important to know how long pre-qualification and pre-approval will be in effect. Different lenders assign different times for which their letters of pre-qualification or pre-approval are good, from 30 to as many as 120 days. Remember that multiple checks for credit history can negatively affect your credit rating, so you don’t want to have them repeated often. For the same reason, you shouldn’t apply for it until you’re ready to start seriously home shopping. Many lenders and real estate agents can help you get a range of what you can afford in a general sense, so that you can avoid going through the pre-qualification or pre-approval process only to learn that there’s nothing in your market that you can realistically afford or want.
