short falls on cash this month and was unable to pay four credit cards, how will this effect a commercial loan application?
Depends on how close the loan application is to being approved.
Since you just missed this month there is no way the late payments will show until the credit card companies report next month.
So if your loan application is approved before these missed payments show up your good to go. If on the other hand the missed payments show before the decision has been made and the creditor see's them your screwed.
Good luck.
slow pays do not look good at all no matter what the application is for. As for the result, cant say for sure because i'm not the underwriter, sometimes it depends how they feel that day/time or if they have had their coffee yet.
but I would say be ready to give reasons why the pmts were late.
