bad credit due to debit consolidation ( should I accept ?)

[Tina Lee]

Hi all, I have an applicant she has 668 credit score and her husband 800. however she explaint her late payment occur on 2017 and all because of debit consolidation company told her to stop payin for all the bill so she can consolidate them. and i was ok to give a benefit of dought 

and ask for extra last month of rent , she didn't want to pay for it. and that had me worried. so over the weekend I did not pick up her call need time to think over now she is back saying she is ok to pay extra month.

should I move on or should I still work with her, at this point i alos saw 5-6 late payment on 2017 ( as she claimed was due to debit consolidation) which I am not familiar with and she did provide me with pay off papers ( some of them show only 70% paid off and account closed.

Should I take chance or should I let it go.
