Ever Done Cost Segregation?

[Jason Powell]

Has anyone ever done a cost segregation without the use of a firm that charges a lot for it? I have a buddy that's doing it himself and providing an excel sheet to a legitimate accountant. Any pros and cons to this?

My motivation is a tax bill for 2018 that my accountant just told me I owe. About knocked me off my seat. My tax rate is above what depreciation recapture is, so I'm ok with whatever the end outcome is upon the property sale (aka I am aware I'm reducing cost basis more) Thanks!
