It is not a problem for your Fiance to have his credit pulled for himself to be pre-approved and then again for the two of you to qualify together if necessary. Since these are for the same mortgage pre-approval and I imagine with-in a few weeks period of time, there will be no damage to his credit.
I hope this helps. Please let me know how I can be of further assistance to you and your Fiance. I have all the resources you need to get started on your home purchase and all the experience and expertise you will want to guide you through the entire process.
Thank you for inquiring.
