Cost segregation: when it makes sense for rental owners
A cost segregation study separates personal property components of a building from the structure itself, so depreciation can be accelerated. Whether it helps depends on the property, the timing, and your income profile. It is a tool with a narrow set of good fits, not a default move.
Who it fits
Owners of rentals with meaningful building basis, investors doing major renovations or acquisitions, and 2 to 10 door owners weighing whether the timing works this year. It matters most when the depreciation actually has income to land against, which is a planning question before it is an engineering question.
What a study actually does
A residential building is depreciated over decades by default. A cost segregation study, performed by a specialist engineering firm, identifies components that can be recovered over much shorter periods: fixtures, finishes, land improvements, and certain systems. The study is the document that supports the treatment.
When it tends to help, and when to wait
It tends to fit profitable years, recently acquired or renovated properties, and owners whose income profile can use the deductions. It tends to wait when the income is not there, when a sale is on the near horizon, or when the building basis is too small for the study to pay for itself.
How Bellamy approaches it
The planning session, $1,500, about 60 minutes recorded, looks at the property, the timing, and your income picture first. When it makes sense, cost segregation coordination runs as a specific project: the firm pairs your property with a specialist study, scopes the coordination on a call, and quotes a firm number before any work starts. Prep itself runs from $650.

What does not work
Every property, every year. Treating the study as a guarantee of a deduction you can use. Running the engineering before the income question is answered.

FAQ
Cost segregation questions.
Does cost segregation work on a small rental?
It depends on the building's basis and your facts. The study has to be worth more than the benefit it unlocks, which is a numbers question before it is anything else. A planning session looks at the property and tells you plainly whether the math can work.
Do I need a study, or can I split components myself?
The standard is an engineering-based study from a specialist firm. Self-prepared splits do not carry the same support, and the study is the document an examination would ask for. The firm coordinates with specialist firms as a specific project, scoped on a call.
Can cost segregation create a loss I can use?
That depends on your income profile and on material participation, which is where REPS and short-term rental facts come in. The acceleration is one piece; whether the resulting loss offsets anything is the other. The two questions get answered together, in that order.
What does it cost?
Studies are priced by the specialist firms, and the price follows the property. The firm does not print a number here because the scope drives it. Coordination is scoped on a call and quoted at a firm number before any work starts.
