What happens after the period of cost segregation study completes?
Hey folks,
I have a fun question on cost segregation study, around which I am trying to build a house hack thesis.
Scenario
Lets say, we have a $1M property ==> Building cost : $800k, land cost : $200k
Now we do a cost segregation study, with following outcome
- $100,000 of interior fixtures and finishes that can be depreciated over 5 years
- $100,000 of interior fixtures that can be depreciated over 7 years
- $100,000 of land improvements that can be depreciated over 15 years
Using a straight line depreciation on cost segregation data, we get
- Building ($500,000 / 27.5 years): $18k
- 5-year property bucket ($100,000 / 5 years): $20k
- 7-year property bucket ($100,000 / 7 years): $14k
- 15-year property bucket ($100,000 / 15 years): $5k
Total first-year depreciation : $57k
Questions
- Do my 5, 7, 15 year property materials cease to provide depreciation after their relevant cost segregation depreciation period is over? (For example in Year 6, I cannot use any depreciation from 5 year bucket)?
- After year 15, am I just depreciating the building?
- Is the attached screenshot a correct way to understand the cost segregation study?
- Is cost segregation study performed only once in year-1 and its values used over and over until 29.5 yrs OR can I perform the study every year? Does it even make sense to perform every year if there's no material change in artifacts used in 5/7/15 yr buckets?

Many thanks!

You're missing the very concept of depreciation. It is deducting the cost of something.
If you have $10,000 worth of something, say appliances and carpets, you can deduct it immediately or over 5 years. But once it's deducted, it's gone. Nothing left to depreciate. You can eat the entire pizza right away or one slice every hour. After that, there's no pizza left, and you need to buy a new one. You cannot cut it again into slices, because it's gone.
Also, it may not work at all on a house hack, which is a completely different conversation.
Please read this post and don't get seduced by tax hype podcasts:
