MEDICAL CORRIDOR
Wash U + BJC: 30K+ Employees

Washington University School of Medicine is consistently ranked top-10 nationally, and BJC HealthCare is the region's largest employer. This medical corridor generates a permanent pipeline of physicians, researchers, nurses, and medical students who need quality rental housing.

FORTUNE 500 DENSITY
9 Fortune 500 HQs at Small-City Prices

Centene, Emerson Electric, Edward Jones, Reinsurance Group, and five more Fortune 500 companies are headquartered here. This institutional employment base would command $500K+ median prices in most metros — but St. Louis delivers it at $220K, creating outsized cash flow and cost seg returns.

BRICK CITY ADVANTAGE
Older Brick Stock = Higher Cost Seg Rates

St. Louis is famous for its brick construction — and older brick homes with modern updates often yield above-average cost seg reclassification rates. Identifiable components from renovations (HVAC, electrical, plumbing, landscaping) on a low-cost basis create exceptional ROI on cost seg studies.

Cost Segregation & Tax Rules in St. Louis, MO

What Gets Reclassified

A cost segregation study identifies building components that can be depreciated over 5, 7, or 15 years instead of the standard 27.5 or 39 years. In St. Louis, typical reclassification rates are 22-35% of building value.

Avg. ROI
10-40x

The math: A $220,000 property with 75% building value and 28% reclassification yields ~$17,094 in Year 1 federal tax savings at the 37% bracket — significantly more ROI than traditional studies costing $5,000-$10,000+.

Housing Stock Advantage

With a median build year of 1980, St. Louis's housing stock has identifiable components (HVAC, electrical, plumbing, landscaping) that are strong candidates for accelerated depreciation.

Full Conformity
Missouri Bonus Depreciation Conformity

Missouri fully conforms to federal bonus depreciation under Section 168(k). The state allows the same accelerated depreciation deductions as the federal government, meaning investors receive both federal and state tax benefits from cost segregation studies.

What This Means for St. Louis Investors: Full conformity means Missouri investors benefit twice — once at the federal level and again at the state level. With a top rate of 4.8%, state savings add a meaningful layer on top of federal deductions. No addback, no modification, no phase-out differences from federal rules.

PeriodFederal TreatmentMO State Treatment
Year 1100% bonus depreciation100% bonus depreciation (full conformity)
Years 2+Standard MACRS schedulesFollows federal MACRS schedules
Section 179 Expensing
State ConformityLimited

Missouri follows federal Section 179 expensing rules. Combined with full bonus depreciation conformity, investors can choose the most advantageous depreciation strategy without worrying about state-level differences.

Key Takeaway

A $230K property with a $179,400 depreciable basis and 28% cost seg reclassification yields ~$18,582 in federal tax savings plus ~$2,412 in Missouri state tax savings in Year 1. Total Year 1 savings: ~$20,994 with full state conformity.

Bottom Line

Missouri is one of the simplest states for cost segregation planning. Full conformity with federal bonus depreciation means one study, one set of calculations, and tax savings at both levels. The recently reduced 4.8% top rate adds ~$1,400–$3,500 in state savings on a typical residential property.

Coverage Recommendations
Wind/hail coverage with appropriate deductible — critical across the state given severe storm frequency
Flood insurance essential near Missouri and Mississippi River corridors and low-lying areas
Replacement cost coverage rather than actual cash value to protect against tornado total loss
Umbrella liability policy ($1M+) for rental properties given storm-related liability exposure
Cost Seg + Insurance Connection

Missouri's severe storm risk makes accurate building valuation essential. A cost segregation study provides component-level documentation that supports precise replacement cost estimates — helping you substantiate insurance claims after tornado or hail damage while ensuring adequate coverage.
