Can we buy a home if my girlfriend has foreclosed before?

I am in the market looking for my first home. My girlfriend has recently foreclosed on a home she owned during her previous marriage. Can we still buy a home together or will I need to seek financing by myself? Can we just use my credit but add her income as well? If we apply jointly and I'm the primary applicant will that be sufficient? I am 26 and make decent money and have a credit score of 730+.
