Sounds like you’re on the right track with your limited debt, congratulations on that. You don’t mention what size down payment you plan to make, and that makes a large difference in the pricing adjustments based on your credit scores. Those costs can addd up to 3% to the cost of the loan for lower down payments and credit scores (below 740), but don’t apply to 15 year mortgages if you go that route. The most lenient program credit score wise is FHA, you’ll get a great rate there with scores of 640 (perhaps a touch lower)but have to pay substantial costs to HUD. As far as co-borrowers go, lenders use the LOWER of the two borrowers' middle credit score, not an average. If you have a 700 score and your husband’s is 620, if both of you are on the loan, you’re considered 620 borrowers. Hope that answers your questions, if you have more, let me know!
