Converted primary to rental. Can I tax deduct primary mortgage?

[Konkova Irina]

Hi Everyone,

Last year I've converted my primary residence into a rental on July 1st, 2021. 
Can I deduct the mortgage interest that accrued while it was my primary residence? i.e the first 6 months of the year? 
I don't have any other mortgage. 

Thank you, guys! This forum is very helpful.
