My advice would be to have a banker/broker/loan officer pull her full credit report and take a thorough look at everything causing the low scores.Quick fixes for just score improvement can be having a family member or a partner add you as an "Authorized User" on a credit card with a 30-40% credit balance to credit limit ratio.
