Quote from @Melanie Baldridge: In 2025 the bonus depreciation rate is 40%.This means that if you bought a property for $1M in 2025, did a cost seg study and found $300K in eligible assets that you could depreciate, you could take 40% of that $300K as bonus depreciation to offset your income in the first year.40% of $300K = $120K.You then apply that $120K to the owner’s personal tax rate to find the final amount that they can defer in year 1.If your tax rate is 37%, you can defer $66.6K.This is a big deal even at the 40% bonus depreciation rate this year.It’s a massive benefit 

They also get a small bonus on every review they generate.

Looking to talk to someone who’s had experience adding a bonus room/sunroom in San Diego.

Here is a newly created resource on BiggerPockets, which touches out cost segregation, accelerated depreciation, bonus depreciation, depreciation recapture, Real Estate Professional Status (REPS), STR Loophole / STR Strategy, example properties, and more.Cost Segregation 101 Author: Sean GrahamHappy to answer questions :)

@Jonathan B.Assuming you pass the "material participation" test for 2023 and did not use the property yourself (or used very little), you should be able to treat it as an STR for 2023, including bonus depreciation.  

Bonus depreciation recapture is based on the year that is placed into services.As of right now, the bonus depreciation for 2024 is 60%.It is not likely that they will change the bonus depreciation retroactively to 2024.If they change the bonus depreciation for properties purchased in 2025, it will have no impact on a property you placed into service in 2024.

I have  a W2 job and look forward to the losses this year to offset some of my income (Not my 'WHY' for running an STR, but a nice bonus).

Assets identified in this study include:Standard windows and doorsInterior ceilings and wallsBasic plumbing and electrical systemsBuilding structural elements and roofingBasic HVAC componentsWater heatersFire protectionThis engineering-based cost segregation study included the following methodology:Physical Inspection through a site visitDocumentation review including architectural plans, accounting records and construction documentsA cost analysis which utilizes engineering principles in order to allocate costs to their applicable asset classificationsCalculation of the depreciation schedule using MACRSAs a reminder, bonus depreciation started to phase out in 2023.

It's all speculation at this point, but we are very hopeful to have 100% bonus depreciation or some form of it reinstated.

Any neighbor that can throw you on a stretcher and take you to the hospital is a bonus.
