Florida v Nevada to avoid state income tax

I’m self employed and will spend the majority of my time outside of whichever state I choose to avoid paying egregious state tax elsewhere.

I’m trying to fully gauge and understand the nuance of this.

Does anyone have experience moving and spending very little time in a tax-free state? If so, any tips, tricks or suggestions?

For context, I will probably spend 9 months out of the year abroad, and maybe only 1 month if that) in whichever state I choose to buy property and get my mail sent to.

Thanks!
