Some may call this financial blasphemy
Bought new house September 2020, used 60 day IRA rollover for down payment. 48 hours after close used a credit card with insanely huge limit and equally insane balance transfer offer of 0% for 12 month to payback IRA. IRA funds went to Roth, taxes already withheld. W4 deduction adjusted to account for tax prepayment.
Planning to sell old house in a few months.
So far it is working out. Socking away cash to pay down insane credit card transfer in case old house sale stretches longer than expected.
