There is no IRS minimum property value for cost segregation — it's purely economic. At traditional pricing ($5K–$15K), the break-even historically sat around $500K. At modern pricing ($495), a $200K single-family rental produces ~$2,100 in first-year tax savings — a 2.6x ROI. A $300K property returns ~$3,200 (4x ROI). Cost segregation produces positive ROI on virtually any investment property above $150,000 at today's pricing.
The minimum property value for a cost segregation study depends primarily on the cost of the study itself. Traditional engineering firms charge $5,000 to $15,000, which historically made cost segregation impractical for properties below $500,000 to $750,000. At those prices, a $300,000 rental property might generate only $5,000 to $8,000 in Year 1 tax savings from accelerated depreciation -- barely covering the study fee. However, at modern tier-based pricing (starting at $495 for properties under $300K, $795 for $300K–$1M), the break-even drops dramatically. A $200,000 single-family rental with 18% reclassification, 80% depreciable basis, and a 37% tax rate generates approximately $5,300 in first-year tax savings -- a 10x return on the $495 study. A $300,000 property returns roughly $8,000 in savings against a $795 study -- a 10x ROI. There is no IRS minimum property value requirement; the question is purely economic. At these prices, cost segregation produces positive ROI on virtually any investment property above $150,000.
The Old Math: Traditional Firms
Here is how the traditional cost segregation industry works. A firm sends an engineer to your property for a site visit. They spend 4-8 weeks writing a report. They charge $5,000 to $15,000. Then they hand you a PDF and disappear.

At those prices, the break-even math is simple:
- A $300K rental might generate $8,000-$12,000 in Year 1 tax savings from cost seg
- If the study costs $7,500, you keep $500-$4,500
- The ROI is 1x-1.6x. Not terrible, but not exciting
That is why every traditional firm tells you cost segregation "makes sense" starting at $500K+. They are not lying. At their prices, it does not make sense below that. But their prices are the problem — not cost segregation itself.
The New Math: $495
Cost Seg Smart is the modern cost segregation company. Same IRS-aligned methodology. Same component-level engineering analysis. Same CPA-ready reports. $495 for properties under $300K, $795 up to $1M. Under an hour.
Watch what that does to the break-even:
| Property Value | Est. Year 1 Tax Savings | Traditional Study ($7,500) Net | Traditional ROI | CSS Study Fee | CSS Net | CSS ROI |
|---|---|---|---|---|---|---|
| $200,000 | $5,328 | -$2,172 | 0.7x | $495 | +$4,833 | 10.8x |
| $300,000 | $7,992 | +$492 | 1.1x | $795 | +$7,197 | 10.1x |
| $400,000 | $10,656 | +$3,156 | 1.4x | $795 | +$9,861 | 13.4x |
| $500,000 | $13,320 | +$5,820 | 1.8x | $795 | +$12,525 | 16.8x |
| $750,000 | $19,980 | +$12,480 | 2.7x | $795 | +$19,185 | 25.1x |
| $1,000,000 | $26,640 | +$19,140 | 3.6x | $1,195 | +$25,445 | 22.3x |
Assumes SFR, 18% reclassification rate, 80% depreciable basis, 37% tax bracket. CSS study fee varies by tier: $495 under $300K, $795 for $300K–$1M, $1,195 for $1M–$2M. Furnished STRs would be significantly higher.
Key takeaway: At $495, cost segregation generates positive ROI on a $200K rental property. At traditional pricing, you would lose money on that same property. The "minimum value" is a pricing problem, not a cost segregation problem.
When Cost Segregation Actually Does Not Make Sense
Let's be real — there are situations where cost segregation is not worth it, even at $495:
- Properties under $100,000: The depreciable basis after land allocation might be $60K-$70K. At an 18% reclassification rate, that is $11K-$13K accelerated, generating roughly $4,000-$4,800 in tax savings. Still positive ROI at $495, but barely. And if you are in a lower tax bracket, it gets tighter.
- Properties you are about to sell: If you are selling within the next year, cost segregation creates depreciation recapture that gets taxed at sale. The timing does not work.
- Properties that are not placed in service: You cannot depreciate a property that is not in use as a rental or business property. A vacant lot or a flip that has never been rented does not qualify.
Outside of those edge cases? If you own rental property and you have not done a cost segregation study, you are leaving money on the table. Period.
The Real Answer
There is no meaningful minimum property value for cost segregation anymore. Not at $495.
A $250K rental generates roughly $6,600 in Year 1 tax savings from cost seg. That is an 8.3x return on a $495 study. You spend more than $495 on a single plumbing call.
A $400K rental generates roughly $10,600 in Year 1 tax savings. A 13.4x return. You would not turn down a 1,340% return on any other investment, so why are you turning it down on your taxes?
The old "minimum value" was never about cost segregation. It was about an industry that charges $5,000-$15,000 for something that should cost $495. Traditional firms have offices to rent, engineers to fly in, and overhead to cover. That is their problem — not yours.
What About Bonus Depreciation?
It gets better. The One Big Beautiful Bill Act (OBBBA), signed in July 2025, permanently restored 100% bonus depreciation. That means every dollar of 5-year, 7-year, and 15-year property identified in your cost seg study is deductible in Year 1. All of it. No phase-down, no spreading it out.
During 2023-2024, bonus depreciation had phased down to 80% and 60% respectively. Those days are over. The full deduction hits your return the year you place the property in service.
This makes cost segregation more valuable at every property value level — especially for lower-value properties where every dollar counts.
STRs and Furnished Properties: Even Better
If your rental is furnished — short-term rental, vacation rental, furnished mid-term rental — the reclassification rate goes up significantly. Furnished properties typically see 22-28% of the depreciable basis reclassified, compared to 15-20% for unfurnished long-term rentals.
That means a $300K furnished STR might generate $12,000+ in Year 1 tax savings. On a $795 study (the $300K–$1M tier). That is a 15x return.
And STRs get the bonus: if your average guest stay is under 7 days and you materially participate, your rental losses are not limited by passive activity rules. Those depreciation deductions can offset your W-2 income. For high-income earners, that changes the math entirely.
Bottom line: If you own a rental property worth $150,000 or more and you have not done a cost segregation study, you are paying more in taxes than you need to.

Frequently Asked Questions
Is there a minimum property value for cost segregation?
There is no IRS-imposed minimum. The practical minimum depends on the cost of the study relative to the tax savings generated. At traditional pricing of $5,000-$15,000, cost segregation only made sense for properties above $750K-$1M. At Cost Seg Smart's pricing starting at $495, the study generates positive ROI on properties as low as $150,000-$200,000. A $250K rental typically produces approximately $6,600 in Year 1 tax savings -- a 13x return on the $495 study cost.
When does cost segregation not make sense?
Cost segregation may not be worth it in a few specific situations: properties under $100,000 (the depreciable basis and resulting tax savings may be too small), properties you plan to sell within the next year (creates recapture that gets taxed at sale before you benefit from the time value), and properties not placed in service as rentals or business use (vacant land and personal-use homes do not qualify for depreciation). For most rental properties above $150K, the study pays for itself many times over.
Do furnished STRs have a lower effective minimum than unfurnished rentals?
Yes. Furnished properties typically see 22-28% of depreciable basis reclassified into accelerated categories, compared to 15-20% for unfurnished long-term rentals. The furniture, appliances, electronics, linens, and outdoor amenities all qualify as 5-year personal property. A $300K furnished STR might generate $12,000+ in Year 1 tax savings from cost segregation. Additionally, STR owners who materially participate can use rental losses to offset W-2 income, which amplifies the benefit at every property value level.
Why did cost segregation used to require a $500K+ property?
The minimum was never about the tax strategy -- it was about the cost of the study. Traditional engineering firms charge $5,000-$15,000 per study because of overhead: physical site visits, travel, office space, and weeks of manual analysis. At that price, a property needed to generate at least $15,000+ in tax savings to justify the cost, which required a purchase price of $500K or more. Cost Seg Smart uses the same RSMeans construction cost data and IRS methodology but delivers reports in under one hour at $495, eliminating the pricing barrier that kept smaller properties from benefiting.
