Cost Segregation and the Short-Term Rental Strategy

What a cost segregation study does

Buildings are normally depreciated over a long period. A cost segregation study breaks the purchase into components — fixtures, appliances, flooring, land improvements — some of which carry much shorter depreciable lives, and some of which may be eligible for accelerated or bonus treatment.

The effect is to pull a large amount of depreciation forward into the early years of ownership, which commonly produces a substantial paper loss in year one.

Why the loss is not automatically useful

A large rental loss that is passive can only offset passive income. For a high-earning owner with no passive income, it sits suspended — real, but not currently useful.

This is the join. The short-term rental position, if it applies, can make that loss non-passive so it can offset ordinary income. Cost segregation creates the loss; material participation determines whether you can use it now. Doing the study without the hours to support the participation position is how people spend real money on a deduction they then cannot take.

The sequencing that matters

The hours are earned across the whole year, and a study commissioned in December cannot retroactively create participation you did not have. Owners who intend to rely on this generally decide early, start logging from the first day of ownership, and keep the average-stay figure under watch all year.

There are also downstream consequences — depreciation recapture on sale among them — that belong in a conversation with your CPA before anything is commissioned, not after.

The unglamorous prerequisite

A cost segregation study is a professional engagement with a real cost. The hours log costs nothing but consistency, and it is the part that decides whether the study pays for itself. Start the log first — from the free template or from STR Tracker — and let the study follow the decision, not the other way round.
