Debt Service?

Question A Qbank question about real estate valuation includes # Annual interest expense = $32,000. # Annual debt service expense = $35,000. What is Debt service? The principal on the mortgage? Or is it just breaking out the interest portion and we are to assume that debt service = 32000 interest +3000 principal = 35000 debt service? Thanks

It’s the payment you make on the loan.
