The answers are all in the previous posts. Some highlights:
A cost segregation study tells you how to segregate specific aspects of any rental property, such as appliances and carpet. You don't accelerate the building. If you made improvements after the purchase, you would automatically segregate them. If you just bought the building and wish to segregate a specific asset, then you need to determine which they are and enter them separately from the house.
You just have to find a way to allocate a reasonable amount to each asset and subtract it from the purchase price
Ok ... the assets are still being depreciated only faster ... so I am not sure where you believe this saves you from having to recapture depreciation in the future when the assets are retired or sold.
