Is it normal to pay part of the mortgage?

Hey everyone, it seems like it’s difficult to get the full mortgage covered + cashflow while living in the other half of a multi family. With the interest rates right now it’s even difficult to just get the full mortgage covered.

Have any of you ever paid a portion your mortgage while living in your house hack? I would only do this if the numbers showed that I would cashflow after moving out. Is this a viable strategy?
