STR Tax loop hole and Tiny Homes

Want to create an Airbnb. Thinking about purchasing land and placing a prefab tiny home on it. There are higher end ones that start at about 100k. Am I able to do cost segregation on a tiny home and if so what % would I expect to get from it.

    Hi @Patrick Howarth, owner of Maven Cost Segregation here.

    Yes, cost segregation applies very well to STRs like your prefab tiny home. These properties, especially new builds, typically yield excellent results due to the significant amount of personal property (5-year assets) and potential land improvements (15-year assets) often included.

    For a new high-end tiny home, it's common to see 25-30% or more of the depreciable basis reclassified to shorter depreciation lives, qualifying for bonus depreciation, but it depends on a lot of factors. This is especially powerful if your STR activity qualifies as non-passive, allowing those accelerated deductions to offset ordinary income. A detailed study is key to maximizing this.

    If you want, happy to run a quick free estimate on a property you’re looking at so you can sanity-check the numbers before committing.

    Yes Patrick, a tiny home can qualify for cost segregation if it’s used as an income-producing rental (not a personal residence).

    If it's operated as a short-term rental (average stay of 7 days or less), it may qualify for the "STR loophole." That allows rental losses to be treated as non-passive if you materially participate (commonly 500+ hours per year, or 100+ hours and more than anyone else). If you qualify, accelerated depreciation from cost segregation can potentially offset W-2 or other active income.

    In a typical cost segregation study, roughly 15–30% of the property’s basis may be reclassified into shorter-life assets (5, 7, or 15 years), which can significantly increase first-year depreciation.

    Under the OBBBA, 100% bonus depreciation for qualifying short-life assets is now permanent for eligible property placed in service after Jan. 19, 2025. That makes cost segregation even more powerful since those reclassified assets can potentially be fully deducted in year one if you qualify.

    Key considerations:

    • Land is not depreciable.
    • Passive activity and recapture rules still apply.
    • The STR rules themselves did not change, you still must meet average stay and material participation requirements.
    • For a $100,000, I would highly recommend online cost segregation software to keep your costs down.

    Whether it’s worthwhile depends on purchase price, income level, and how actively you manage the property.

      Completely agree with @Gian Pazzia. For a $100,000.00 property, online cost segregation software is a smart, cost-effective solution. It allows owners to capture accelerated depreciation benefits without the higher fees of a full engineering study, making it a practical option for lower-priced assets where keeping costs down is key.

    You can absolutely cost segregate a tiny home used as an STR, as long as it qualifies as depreciable real property and is placed in service as a rental.

    For STRs, the key factors are:

    First, the average stay rule. If the average guest stay is 7 days or less , the activity is not treated as a traditional rental under the passive activity rules.

    Second, the 100-hour material participation test. If you materially participate and work at least 100 hours — and no one else works more than you — the activity can be treated as non-passive. That’s what allows losses to offset active income.

    Now that 100% bonus depreciation is back, cost segregation becomes even more powerful. If, for example, 25–40% of a $100,000 tiny home (excluding land) is reclassified into 5-year or 15-year property, that portion could potentially be written off immediately in year one, assuming you qualify and materially participate.

    Yes, you can potentially do cost segregation on a tiny home, but it depends on how it’s set up. If the tiny home is permanently affixed to the land with a proper foundation and utilities, it’s generally treated as real property and eligible for depreciation, including accelerated components like electrical, plumbing, and certain fixtures.

    That said, on a $100K structure, you’ll want to weigh the benefit against the cost of a formal cost segregation study. On smaller properties, sometimes partial acceleration without a full study can still create meaningful front-loaded deductions.

    If you're operating it as a short-term rental and you materially participate, you may be able to avoid passive loss limitations. That's what many people refer to as the STR "loophole," but it only works if you meet the participation and average stay requirements.

    Also remember that land is not depreciable, so proper allocation between land and structure matters. The strategy can absolutely work, just make sure the numbers and structure support it before moving forward.

    Your best bet is to go to 2-3 cost segregation firms and ask for a free analysis.
