- The median Miami STR generates ~$53,000 in Year-1 federal tax savings on a $725K Wynwood townhouse at the 37% bracket with 100% bonus depreciation under OBBBA (2025+). Engine-truth reclassification: 28.2% of depreciable basis into 5/7/15-year MACRS classes — slightly above national STR median due to year-round international tourism FF&E demand and Florida hurricane-code premium systems.
- Miami land allocation runs 18%–38% depending on neighborhood, per Miami-Dade Property Appraiser records. Premium urban-core (Coconut Grove luxury) hits 38%; Brickell tower-density runs 36%; Wynwood post-redevelopment runs 28%; inland workforce neighborhoods (Doral, Kendall, Hialeah) run ~18%.
- Miami Beach STR ban does NOT affect federal cost segregation eligibility. Miami Beach Section 142-905 restricts STR operations to specific RM zones, but federal depreciation depends on the property generating rental income — not on the rental's permit class. Owners pivoting from STR to LTR still capture cost-seg benefit at LTR (~19%) reclassification.
Cost segregation is a 25-year-old US tax strategy with most of its industry data locked behind paid reports or major-firm marketing claims. Miami's massive 2010–2024 condo and mid-rise boom plus year-round international tourism create a particularly clean dataset: a city with consistent property-type composition (Brickell/Edgewater high-rise, Wynwood mid-rise, Coral Gables luxury SFR, Miami Beach historic) and well-documented Miami-Dade Property Appraiser records.
This page publishes Miami-specific cost-segregation benchmarks as an open dataset. Numbers are engine-truth outputs from the Cost Seg Smart cost segregation engine, calibrated against RSMeans 2024 construction cost data, MACRS classification per Rev. Proc. 87-56, and the IRS Cost Segregation Audit Techniques Guide (Pub 5653). Land allocation reflects Miami-Dade Property Appraiser typical ratios. CC-BY 4.0; cite with attribution.

Land allocation by Miami neighborhood
Land is non-depreciable, so the share of purchase price allocated to land directly determines what's available to reclassify. Miami runs a wide range — luxury Coconut Grove pushes 38%; inland Hialeah and Doral stay ~18%. These ratios are Miami-Dade Property Appraiser-typical based on 2024–2026 records:
| Neighborhood / area | Typical land % | Notes |
|---|---|---|
| Brickell (33131) | 36% | Tower-density financial district, condo-heavy |
| Wynwood (33127) | 28% | Post-2010 warehouse-redevelopment art district |
| Edgewater (33137) | 32% | Bayfront condo + townhome corridor |
| Coconut Grove (33133) | 38% | Luxury established, large lots, mature canopy |
| Coral Gables (33134) | 35% | Luxury established, City Beautiful master plan |
| South Beach / Miami Beach (33139) | 34% | Historic Art Deco district, STR-restricted zones |
| Little Havana (33135) | 22% | Older inland residential, Calle Ocho corridor |
| Other Miami (Doral, Kendall, Hialeah) | 18% | Suburban / workforce baseline |

Why Miami produces above-national-average cost-seg ROI
- No Florida state income tax. Federal cost-seg savings are the entire benefit. No decoupling math, no state addback, no parallel state schedule. Compared to California or New York, where state-level §168(k) decoupling requires a parallel state schedule, Florida is among the cleanest cost-seg jurisdictions in the country.
- Year-round international tourism. Art Basel (December), Ultra Music Festival (March), Formula 1 Miami GP (May), Miami Open (March-April), Latin American + European seasonal tourism. Premium FF&E loadouts compete on event-week and high-season pricing — designer furnishings, premium audio, hurricane-rated outdoor amenities — all 5-year personal property under MACRS. Miami STR FF&E density typically runs $40,000–$80,000 per property.
- Sweet-spot construction era. Brickell tower density 2010-2024, Edgewater bayfront 2010-2024, Wynwood warehouse redevelopment 2010-2020, Mid-Beach 2008-2020. Modern construction with code-current HVAC, electrical, fire suppression, smart-building systems all classify as 5/7-year property — not 27.5/39-year structural shell.
- Hurricane-code premium systems. Florida's 2002+ Building Code mandates impact-rated glazing, premium HVAC with surge protection, hardened electrical, continuous-load roofing. While the structural shell stays 27.5/39-year, the premium mechanical systems push 5/7-year reclassification 1-2 percentage points above non-coastal markets.
Florida tax context
Florida has no state personal income tax. The federal Year-1 cost-seg deduction is the entire Year-1 tax benefit — there's no parallel state schedule to maintain. Property tax in Miami-Dade is moderate (effective ~1.0% of market value for non-homestead residential), and Save Our Homes 3% cap + 10% non-homestead cap limit annual property-tax growth. Property-tax level doesn't change federal depreciable basis.
Compared to Nashville and Austin: similar tax structure (no state income tax), but Miami's year-round international tourism drives higher consistent STR FF&E demand. Compared to Atlanta: Miami is materially better for cost-seg ROI because Georgia has 5.49% state income tax. For cross-state comparison, see Cost Segregation Benchmarks 2026.
Miami Beach STR context (and why it doesn't break cost seg)
Miami Beach Section 142-905 governs short-term rental operations, restricting STR to specific RM-1, RM-2, RM-3 zones (essentially banning STR in single-family residential zones since 2018, with limited exceptions). The City of Miami proper has different, less restrictive rules. Miami-Dade County has its own framework.
However: Local STR zoning eligibility does not affect federal depreciation. The IRS depreciable basis is your acquisition cost from the closing disclosure plus subsequent capital improvements minus land value — none of these change based on local STR permit status. Even owners forced to convert from STR to LTR or annual lease still capture cost-seg benefit. The FF&E that no longer functions as STR personal property gets reduced (you'd remove non-affixed furniture from the next study), but 5/7/15-year structural component reclassification stays intact. LTR cost seg in Miami reclassifies 19% of basis vs 28% for STR — meaningfully different, but still a positive return on the study cost.

Frequently asked
What's the typical Year-1 federal tax savings on a $700K Miami short-term rental?
Approximately $52,500 at a 37% federal bracket with 100% bonus depreciation under OBBBA (2025+). The math: $700K × 72% (after typical 28% Wynwood land allocation) = $504K depreciable basis × 28.2% accelerated reclassification = $142K reclassified into 5/7/15-year MACRS classes × 100% bonus × 37% bracket = $52,540.
What's the average land allocation in Miami for cost segregation?
18% to 38% depending on neighborhood, per Miami-Dade Property Appraiser records. Brickell ~36%, Wynwood ~28%, Edgewater ~32%, Coconut Grove ~38%, Coral Gables ~35%, South Beach ~34%, Little Havana ~22%, Other Miami ~18%.
How much does a cost segregation study cost in Miami in 2026?
$495 (under $300K), $795 ($300K–$700K), $895 ($700K–$1M), $1,295 ($1M–$2M), $1,595 ($2M–$5M), $1,895 ($5M–$15M) for residential. Multifamily 2–4: $995–$1,995. Commercial: $995–$2,995. Most Miami residential lands in the $895 or $1,295 tier.
Why does Miami produce above-average cost-seg savings?
Florida no state income tax + year-round international tourism (Art Basel / Ultra / F1 / Miami Open) drives STR FF&E density + Brickell/Edgewater 2010-2024 condo boom hits sweet-spot construction era + Florida 2002+ Building Code mandates premium hurricane-resistant systems classified as 5/7-year property.
Does Miami Beach's STR ban affect cost segregation?
No. Miami Beach Section 142-905 restricts STR operations to specific RM zones, but does not affect federal depreciation. Owners forced to convert from STR to LTR still capture cost-seg benefit at LTR (~19%) reclassification rather than STR (~28%).
Does Miami-Dade reassessment affect cost segregation?
No. Miami-Dade Property Appraiser annual reassessments affect property tax (your TRIM notice and tax bill), not the IRS basis used for federal cost segregation. Your cost-seg basis is your acquisition cost from the closing disclosure plus subsequent capital improvements minus land value.
