Exactly. That is largely how commercial lending is underwritten: by ensuring the DSCR (debt service coverage ratio) is over 1.0.
Sure that is commercial lending.* And the acquirer owes the debt. But that's not how LBOs work. In an LBO the target owes the debt. *Coverage of 1:1 is an accident waiting to happen, but otherwise sure.
If PE firm A wants to buy company C using an LBO, it could do so by having C borrow money and then A purchase C, or by creating an entity B that borrows money and then purchases C. Whether B or C owns the debt doesn't change anything meaningful for A, and it's pretty clear that you're allowed to form company B (and really hard to imagine how you'd make that illegal without effects that would be worse than current).
