Our mortgage is still ongoing?
The mortgage of our house is still going
I have the same query
I prefer "outstanding" for "masih berjalan". "Outstanding" is a common financial term, meaning "some debts have not been paid off yet".
Looked it up online and "mortgage" is translated as "hipotek" not "kredit rumah".
Did you google the term "kredit rumah"? As far as I know, BCA is one of the major banks in Indonesia. BCA offers "Kredit Pemilikan Rumah" -- the direct translation is "house ownership credit", which is pretty much the same as mortgage.
