Interest deductable for cash out refinance

[Selina Gruden]

HI Real Estate friendly CPAs,  I have a question regarding to interest expense deductible for cash out refinance.

We did a cash out refinance for our primary residence in Nov, 2021, loan proceed is $755k. Paid off the original home loan 500k + 10k closing cost. Using the rest 245k cash + 55k personal cash for:
1. Primary home renovation: 55k, project won't complete until May, 2022
2. Using 100k refinance cash for the downpayment of 2nd home (short term rental), and taking another loan for the balance, closing on 2/1/22
3. Using 145k refinance cash purchase another rental property, closing on 3/1/22
How can I file my interest deductible for 2021 tax and 2022 tax?  Item 2,3 distribute from the same personal account that 245k was in, while 55k comes from another personal account.
Can I deducted interested related to 245k cash out which secured by primary home for investment interest? Or I should allocate 55K for renovation and rest 190k for investment? 
For interest related to primary residence, the loan amount is 500K+10K closing cost or just 500K?

It seems too complicated and I can't get my head around it. I would love to hear some of the suggestion.

Thank you!
