Mortgage Approval Process-Need credit advice

[Kristi Williams]

Is it a requirement to pay off all collection accounts or charge offs from years ago to get approved for a mortgage. I have 1 collection account, which shows as a collection account. I then I 3 accounts that show charge off, they said paid and closed-however they are listed under the open accounts section on my credit report and just say $0 Paid; closed. All the accounts are from 2016 and 2017 when I was laid off and then we had a major hurricane and I was unemployed for a year. I can now pay them off, but is it required? Or what is best approach to getting approved for a mortgage when it comes to charge off's and collections? One account is $500 and all the others are under $150.00. 

Thanks,

K
