I need help deciding whether to take 100% depreciation in first year or spread it out over several years.

[HollyP]

By taking the depreciation all in the first year (Section 179), you'll  be able to decrease your net business income by increasing your deductions in the tax year you acquire an asset. If your business is operating at a profit, it's to your advantage to claim the Section 179 deduction.

By depreciating over a period of years, you'll be able to decrease your net business income a little bit each year. If you expect your business to continue to operate at a profit, and you want to ensure you'll have deductions in the future then its advantageous to depreciate it over time.

Can you take 100% depreciation in the 1st year with residential properties?

I thought this was only commercial or mixed use.
