Organized, room-by-room property documentation prepared for your CPA and cost-segregation engineering firm. Better documentation inputs lead to more efficient studies—and potentially more accurate analysis.
When your CPA recommends a cost segregation study for your short-term rental property, the engineering firm conducting that study needs detailed property information to do their work: fixture inventories, photographic documentation, room-by-room breakdowns, appliance and furnishing lists, and more.
Most investors don’t have that documentation organized in a format that engineering firms can use efficiently. Gathering it yourself takes time, and doing it without a framework often results in gaps that slow the study down.
STR Advisors prepares that documentation file using a guided SMS-based photo intake process. You photograph the property on your phone using our room-by-room framework. We organize the output into a structured documentation file formatted for CPA and engineering firm handoff.
The One Big Beautiful Budget Act, signed into law in July 2025, restored 100% bonus depreciation under IRC §168(k) for qualified property placed in service after January 19, 2025. This reverses the annual phase-down that had reduced bonus depreciation to 60% in 2024.
For STR investors, this restoration may have significant implications. Cost segregation studies reclassify components of a real property into shorter depreciation life categories (5, 7, or 15 years under MACRS). When combined with 100% bonus depreciation, the reclassified components may be fully deductible in the year the property is placed in service—rather than over 27.5 or 39 years.
What we can do is prepare the property documentation that your CPA and the engineering firm will need to conduct that analysis efficiently. Better documentation leads to a faster and more accurate study.
Fill out the Cost Seg Packet intake form. Tell us about the property—type, size, when it was placed in service, and whether it’s already operating as an STR.
We send you a guided room-by-room photo intake framework via SMS. Walk through each room of the property photographing fixtures, appliances, land improvements, and structural components per the framework.
Your photos and notes are compiled into a structured documentation file. We catalog fixtures room by room, note appliances and personal property, and identify any land improvement features photographed.
The completed documentation package is delivered in a format ready for your CPA’s review and for the engineering firm conducting the cost segregation study. You can share it directly or we can coordinate the handoff.
