The Opportunity You May Be Missing

Most multifamily investors pay more tax than they need to

If you own multifamily real estate and you're not actively combining depreciation, cost segregation, mortgage interest deductions, Section 199A, and exit-side strategies like 1031 exchanges and the step-up in basis — there's a strong chance you're leaving real money on the table every year.

"After-tax returns are what build wealth. Pre-tax returns just look good on paper."

The U.S. tax code is unusually generous to multifamily real estate. Depreciation alone can transform a cash-flowing property into a paper-loss generator. A cost segregation study can pull a decade of deductions into year one. A properly structured 1031 exchange can defer gain indefinitely. And the step-up in basis at death can eliminate that deferred gain forever.

This 64-page educational guide gives you the conceptual foundation and strategic vocabulary to ask sharper questions of your CPA, evaluate syndications more rigorously, and ensure no significant strategy goes unconsidered in your portfolio.

Key Strategies Covered

Ten strategies that compound across your portfolio

The most powerful tools in the multifamily tax toolkit, explained with worked examples and the rules that govern them.

Cost segregation acceleration

Reclassify 20–40% of depreciable basis into 5-, 7-, and 15-year buckets — turning a flat depreciation schedule into a front-loaded one.

Bonus depreciation stacking

Combine cost segregation with bonus depreciation to deduct large portions of property in year one — even when the bonus percentage is phasing down.

Real Estate Professional Status

Convert otherwise-passive losses into ordinary-income offsets, unlocking the largest available shelter for high-income real estate families.

The Section 199A bonus

Layer a 20% pass-through deduction on top of every other deduction by qualifying your portfolio under the rental real estate safe harbor.

1031 like-kind deferral

Roll capital gains and depreciation recapture forward indefinitely by exchanging one investment property for another within the statutory windows.

Opportunity Zone exclusion

Defer outside capital gains and — with a ten-year hold — permanently eliminate all appreciation on a Qualified Opportunity Fund investment.

Tax-free cash-out refinance

Access trapped equity without triggering tax. Refinance proceeds are not taxable income, and the interest on the new debt remains deductible.

Roth SDIRA real estate

Hold direct real estate or syndication interests inside a Roth IRA for tax-free growth and tax-free distributions for life.

Suspended loss release

A fully taxable disposition frees up every dollar of suspended passive loss accumulated on that property — including against non-passive income.

Step-up at death

The basis of inherited real estate resets to fair market value, permanently eliminating all accumulated capital gain and depreciation recapture.

Real Numbers, Real Math

A worked first-year example

Just one of several detailed walk-throughs included in the book — illustrating the combined power of cost segregation and bonus depreciation on a typical mid-size multifamily acquisition.

Hypothetical Property Profile

$1,000,000 Multifamily Acquisition

Purchase price: $1,000,000 Land allocation: $200,000 Depreciable basis: $800,000 Investor bracket: 37% federal
ComponentWithout StudyWith Cost Seg + Bonus
5-year personal property ($140,000)$0$140,000
15-year land improvements ($80,000)$0$80,000
27.5-year structural property ($580,000)$29,091$21,091
Year 1 depreciation deduction$29,091$241,091
Additional first-year deduction+$212,000
Estimated First-Year Federal Tax Savings
~$78,400

At a 37% marginal rate, the additional first-year deductions translate into real federal tax savings — cash that can be redeployed into the next acquisition. This is hypothetical and illustrative only; actual results depend on countless variables specific to your situation.
