Rental upgrades 1 year write off?

[Kenneth Ginder]

We're updating the fencing, replacing a dated leaky porch entry, taking out a dead tree this year (2023). Can we business expense all of these projects in the same year. Or do these larger upgrades/updates need to be apart of a cost segergation study? We also have more projects that we plan to hire out in the next few years. ( replaces old wooden single pane windows, replace collapsing porch and updated very old plumbing). Can we write off each year we knock out a project. Or should we do a look back cost segergation study when all of our projects are completed?
