For CPAs advising residential rental clients, the most practical question is what actually gets reclassified into shorter-life property, and how to keep it defensible.
RentalWriteOff delivers engineering-level documentation depth in a cost segregation documentation package, typically in 2 business days, with a streamlined intake requiring about 5 minutes of client time. CPAs can submit through our Partner Portal, partnership programs are available, and audit support is included with every report we deliver.

The CPA mental model: 27.5-year building vs. shorter-life components
In residential rentals, the building structure generally remains 27.5-year property, while certain components and site improvements may qualify for shorter recovery periods when properly identified and supported.
Common 5-year and 7-year components in residential rentals
- Appliances and equipment (especially in furnished rentals)
- Furnishing-related items when the property is furnished
- Specialty electrical/plumbing serving specific equipment (facts and scope matter)
- Other personal property components identified through documentation and property evidence
Common 15-year land improvements
- Walkways, driveways, and hardscapes (where applicable)
- Fencing, exterior lighting, and landscaping improvements (facts and documentation matter)
- Site-related improvements supported by photos, surveys, and/or invoices
Bonus depreciation planning tie-in
Shorter-life property may increase eligibility for bonus depreciation depending on the year placed in service and applicable tax rules. RentalWriteOff includes bonus depreciation applicability analysis; the CPA controls elections and final filing treatment.
CPA note on defensibility
Appraisal support, closing documents, invoices, and photos materially strengthen basis allocation and classification support, particularly when construction-level records are unavailable.
