Average Cost Segregation Percentage Depreciation?

[Michael P.]

For those of you who have conducted a Cost Segregation Study, what percentage did it allow you to depreciate?

Please also state what type of property you have.

For example, Single Family, Duplex, Townhouse, etc.  

I'm trying to get a ballpark % I could depreciate if I were to purchase existing or build new residential properties.  

Thank You!
