Cost Segregation - After regular long term depreciation?

[Spencer Dixon]

I have a single family rental property that has been rented for two years. I've done the normal long term depreciation of the property.

My question: Can I do a cost segregation even though in previous years I've taken the standard depreciation

I am a real estate agent, self manage the property, should qualify for all the benefits of being full time in the business of real estate. I'm hoping to wipe out a substantial amount of my taxable income this year.

Any advice would be lovely
