If YOU have good credit and you would qualify for better terms.... you can buy the house and then add your husband after the fact with a quick-claim-deed. It's pretty easy.
I'm not sure of the severity differential.... but with a bankruptcy that DIDN'T involve a forclosure, it was the magic 10 year mark before interest rates lower and "points" disappear due to the bankruptcy on your credit.
My question would be.... what got you into trouble in the first place and have you taken steps to clean up your credit since then? ie - yes the market was bad.... but plenty of people bought homes 5 years ago and DIDN'T forclose... what was special about your circumstances.... did you buy over your limit, lose a job, no savings plan, over spending?
These things will make a difference to future creditors. They want to see how you have changed behaviors that got you into trouble last time.
Also - only putting 3.5% down will get you upside down on a mortgage really quick. I wouldn't advise doing that.
