cost segregation study for real estate investors

[Room42 @GetRoom42]

Section 179 doesn't work on residential rentals the way it works for a business's equipment. Rentals get bonus depreciation instead — same 5- and 7-year property, different door. If your CPA says 'just 179 it,' ask which door they're using.

Inherited a rental? The step-up resets your depreciable basis to fair market value at death. A cost seg on that stepped-up basis often pencils where it wouldn't have for the original owner. Run it by your CPA.

Office furniture, appliances, and most fixtures in a rental aren't 27.5-year property. A cost seg usually reclassifies them to 7 years — and 100% bonus applies if acquired after Jan 19, 2025. Run the numbers with your CPA.

In a triple-net lease, the landlord can't depreciate improvements the tenant paid for — basis follows who paid. A cost seg study only covers the landlord's own costs, so check who actually paid before counting the deduction. Run it by your CPA.

Big first-year cost seg deduction? If you're a noncorporate taxpayer, the §461(l) excess business loss cap can limit how much of it you can use this year — the excess carries forward as an NOL. Model the cap before you celebrate it. Run it by your CPA.

@FitUFinance That $100Ks moves a lot by property type — an office reclasses a very different share than a warehouse. And it only helps if you can use the loss that year; passive and excess-business-loss limits trap a lot of first-year paper losses. Worth modeling with your CPA first.

Placed a rental in service in 2026 and haven't done a cost seg yet? You haven't missed it. The study can finish after year-end — the depreciation still belongs to 2026. Run it by your CPA.

Parking lots, sidewalks, fencing, landscaping — on a rental these aren't 27.5-year building. They're usually 15-year land improvements, and that shorter life is where a cost seg finds a lot of its value. Run it by your CPA.

[Room42 @GetRoom42]

@LaAppraiser1 Land allocation is the part people rush past. Get it wrong and you're either depreciating land or under-depreciating the building. A defensible number at purchase saves a lot of arguing later.

[Room42 @GetRoom42]

Cost seg doesn't pay on every rental. Low basis, cheap purchase price, or a property you'll sell in a year or two — the study fee can eat the benefit. Run the math before you pay for one.

[Room42 @GetRoom42]

In a rental, 5-year property isn't just appliances. Carpet, vinyl plank, window treatments, ceiling fans, and dedicated outlets usually qualify too. A cost seg study is mostly about finding that stuff.

[Room42 @GetRoom42]

Buy a rental with a 1031 exchange and your depreciable basis carries over from the old property — you don't get a fresh step-up to the new price. That changes the cost seg math. Run it by your CPA.

[Room42 @GetRoom42]

The $2,500 de minimis safe harbor lets you expense small rental items instead of capitalizing them — but you have to elect it on your return, every year. Miss the election, miss the deduction. Run it by your CPA.

[Room42 @GetRoom42]

A cost segregation study doesn't change what you paid. It re-sorts parts of the building — carpet, fixtures, site work — into shorter lives so depreciation lands earlier. Same total, different timing. Run it by your CPA.

[Room42 @GetRoom42]

Residential rentals depreciate over 27.5 years, commercial over 39. Same building cost, very different annual deduction — that's why property type matters before you buy. Run it by your CPA.

[Room42 @GetRoom42]

@ImperialAssets7 Close, but that $10k only works if the full $300k is the building. Land isn't depreciable, so the depreciable basis on a $300k purchase is less. And a paper loss is usually passive — it may not offset other income unless you qualify. Run it by your CPA.

[Room42 @GetRoom42]

@PolyPup @MidwestCowboy6 Worth adding: 750 hours is only half the real estate professional test — it also has to be more than half your total working time. And a cost seg doesn't create deductions, it pulls them forward. Both matter before counting on offsetting other income — run it by your CPA.

[Room42 @GetRoom42]

If you renovate the inside of a nonresidential rental — new flooring, lighting, HVAC inside the building — that's usually 15-year qualified improvement property, not 39-year building. Same renovation, very different depreciation clock.

[Room42 @GetRoom42]

100% bonus depreciation didn't expire. It's permanent now for property acquired after Jan. 19, 2025. The Dec. 31 deadline that matters is your tax year — the property has to be placed in service in 2026 to count for 2026.

[Room42 @GetRoom42]

@get2hans @Fl0ridaGators @rahul_bijlani @TripleNetInvest This is the part cost seg sellers skip. The 5- and 7-year property you bonus in year 1 comes back as ordinary §1245 recapture at sale — the building portion is the only piece capped at 25% under §1250.
