Cost Segregation Can't Save a Bad Real Estate Deal (Here's What It Actually Does)

<p>Can a cost segregation study rescue a bad real estate deal? No. But cost segregation can turn a marginal rental property into a genuinely good one for the right investor, and this episode shows exactly where that line sits, with real numbers.</p><p></p><p>It started with a Reddit post: close on the deal, do a cost seg study, and let the depreciation bail you out. Hundreds of upvotes. It's wrong, and believing it can cost you real money. David Wiener, Mr. Cashflow, breaks down what a cost seg study actually does, who can use the losses it creates, and the bill that shows up later that nobody online mentions.</p><p></p><p>What's covered:</p><p>Why cost segregation is a timing tool, not free money. It moves write-offs you were always going to get from year 15 up into year one. Useful, yes. The same as creating value, no.</p><p>How 100% bonus depreciation changed the math, and why a 27.5-year versus a 39-year depreciation schedule catches short-term rental owners off guard.</p><p>Depreciation recapture, the part that never makes the Reddit thread. Building write-offs come back at a rate capped around 25%. The pieces a study carves out come back at ordinary income rates as high as 37%, plus net investment income tax in some cases.</p><p>Passive loss rules. By default these losses get parked until you have rental income to offset or you sell. Two ways to use them now: qualifying as a real estate professional, or the short-term rental rules for properties with an average stay of seven days or less that you actively run.</p><p>A full worked example on a $500,000 short-term rental. $100,000 land, $400,000 building, a study that finds 25%, roughly $97,000 of extra year-one write-off and about $36,000 in tax savings at the top bracket. Same study, two deals. On a marginal property it flips an $8,000 annual loss into roughly $28,000 in your pocket. On a property bleeding $40,000 a year, you're still underwater, and by year two the cushion is gone.</p><p>The five-step test to run before you sign a contract, including the zero benefit question that settles it in ten minutes.</p><p>Cost segregation studies referenced here are engineering-based and delivered through CSSI.</p><p></p><p>⏱️ CHAPTERS</p><p>00:00 [Add chapters after upload]</p><p>Want to know whether a specific property belongs in the cost seg pile or the walk-away pile?
