Your credit scores are great, and your combined income is, too. It will depend on how much you are trying to finance and how much you have to put down. If you would like to speak with a few good mortgage people, email me and I'll give you some names and phone numbers. Since you are not married, you might find that your salary will enable you to get grants, down payment assistance, etc. However, once you are married, I believe, you will have too high a combined income to qualify.
I am not a mortgage specialist, so I advise you to speak with a few to find out your best options.
