Understanding Deep ITM Leaps

Hiii, I want to make sure I understand it right. I did lot of homework to understand leaps deep itm call options. Let's talk about Google stock. I want to only buy deep ITM since I feel they are less risky as a beginner. The current IV for google is historically lowest from the last 1 yr. Even the volatility is lowest in the last 1 yr. I calculated leverage and it comes out to be 2.6 which I believe is a good buy. My current understanding is that if I buy a deep itm leap call option, I plan to sell it back during high volatility season and since it's a leap I have a lot of time. I think I should try to sell it irrespective of the expiry option before 3-4 months since theta decay starts to ruin everything. I want some feedback on this strategy since this is my first time and I'm a bit nervous clicking the buy button.
