How much do paid off personal loans matter?

[EaglesFan2006]

Does it matter how many personal loans you have when looking at a new mortgage loan if they're paid off?  Meaning if you have good scores, DTI, etc but a history of personal loans, would that negatively impact you?   Or does it really not matter as much if they're paid off

For majority of mortgages it has no direct impact.  Although a bunch of paid off debts (credit cards, student loans, personal loans, mortgages, automobile loans, etc.) that have positive payment history would only benefit you as it shows you've been able to manage credit. 

Scenarios where not having a lot of past credit would hurt someone is if they were qualifying for a jumbo mortgage, a non-QM loan program or their loan needed to be manually underwritten.  In those situations underwriters are looking for a minimum amount of tradelines and history, some just needing 3 tradelines for least 12 months old and on the other end of the spectrum I've seen a jumbo loan program require 5 tradelines for 48 months, including 1 installment loan with 24 months history.
