Dose refinancing changes the loan origination date

[mehranariani]

In 2020 I refinanced my loan which had the origination date of 2011.  Dose this translate that from here  forward my origination date will be 2020. This has large impact for tax deduction limits.

Thanks

The mortgage origination date would be the date you refinanced in 2020. 

When you refinance a mortgage (in this case a new lender), the old mortgage ceases to exist - it becomes a new mortgage. 

A new lender, new borrowers, new term, new interest rate, or new principal balance (cash-out or pay-down) would all mean that you got a new mortgage (some minor modifications excepted).
