Cost Segregation Study for SFRs

[Riley Schaefer]

Has anyone ever done a cost segregation study for a portfolio of SFRs?  Is it worth it, and if so, in what circumstances?

I will likely be making more in the next 5 years than I will after that as I plan to partially retire and live mainly off of rental income in the next 3 to 5 years.  I make good income now that I want to try to maximize my tax deductions as much as possible while I have high income.  Any guidance would be appreciated!
