Is it possible to use a 0% APR loan to accelerate amortization?

[Austin Bright]

Say the following:

1 I live in a duplex and rent out the other side

2 I take out a 0% interest loan/credit card and pay the principle (ahead of schedule)

3 I "pause the mortgage" (ie "Mortgage Forbearance")

4 I use money from my tenant to pay off the 0% rate loan credit card while my mortgage is "paused"

5 Once the credit card is paid, continue as normal?

Is this something people have done to get equity up front? Is it even possible
