Cost Seg Tax questions

[David Frost]

I have multiple SFR properties in different states, all under my LLC. I am not a full time real estate investor and have a day job. Can I use cost seg studies to accelerate depreciation and offset my personal taxes? One CPA said no because Real estate isn't my full time job and income is passive.

Also anyone have a recommendation for a CPA in SoCal that can advise/file my personal and LLC tax returns that is familiar with real estate investors?

Thanks in advance,

David
