Depreciable expenses vs rental revenue income tax

[Hannah Joy]

What is the magical ratio of one time capital expenditures to capture enough 100% depreciation to neutralize income taxes on rental revenue? I know it exists...

If I buy one property a year and do extensive renovations, I'd like to know the percentage of renovations to potential revenue to bake in to the plan so my taxes are low but due to the add back nature of the depreciation I still show revenue to be lendable for the next one.
