investors are breaking even.

How a Cost Segregation Study Works for Multifamily

By using cost segregation for apartment buildings, you’re freeing up income in the first few years of ownership, often when investors are breaking even. Cost segregation studies allow investors to break down the tax depreciation into parts.
Typically, investors can depreciate the cost of an apartment complex over 27.5 years using the straight-line method.
But with a cost segregation study, you can depreciate certain parts of the apartment or multifamily more quickly. This includes interior finishes, cabinetry, and appliances, any assets that do not compromise the structural stability of a multi-family building
These items can be fully depreciated in as little as 5, 7, or 15 years.

Does a cost segregation study for apartments/multifamily change by state?

At National Cost Segregation Services, we are proud that our expertise serves every region of the U.S. A cost segregation study for apartments and multifamily properties identifies assets that may be eligible for a shorter depreciation schedule under the IRS guidelines. A cost segregation study is based on federal tax law, which means it’s applicable in any state.

While the method of cost segregation is the same state by state, the result varies. Some states follow the exact federal depreciation rules, while others limit or adjust certain deductions. This means one multifamily owner may see one result on their federal tax return and a different result on their state return.

Because National Cost Segregation Services works with apartment and multifamily property owners across the country, our studies are designed to support the federal depreciation strategy while providing your CPA with the detailed information needed to evaluate any state-level adjustments.

Cost Segregation Study and Remodeling

One of the strongest opportunities for a cost segregation study for apartment and multifamily properties is during renovation. 
When owners renovate units, they often add assets eligible for depreciation in a cost segregation study.One of the strongest opportunities for a cost segregation study for apartment and multifamily properties is during renovation.
When owners renovate units, they often add assets eligible for depreciation in a cost segregation study.
Depending on the asset, certain items may be moved into 5-year, 7-year, or 15-year property categories instead of staying on the full 27.5-year schedule.
For apartment and multifamily owners, renovations often include a mix of structural building costs and shorter-life assets. A cost segregation study is the best way to separate these costs, ensuring the depreciation schedule accurately reflects the property.
With the help of a cost segregation expert, owners can generate significant deductions by analyzing contractor invoices, construction budgets, purchase receipts, project timelines, and placed-in-service dates to determine which costs may be eligible for accelerated depreciation.
