financing & tax debts

[Dale Cooper]

This is probably a stupid question, but please bear with me. Entity paid cash for 10 properties (4 unit rentals) a few years ago and has been operating them debt-free since. Unfortunately, taxes were not paid (since 2010).

We are now approaching banks to take out some debt on the properties before interest rates go up. Are banks going to uncover these tax issues?

In other words, will I be able to get financing and pay the old taxes with the financing proceeds? Or will I be blocked from financing until old taxes are resolved?
