Five Myths About Cost Segregation That Are Costing Investors Money

Cost segregation has been around for decades, but a surprising number of property owners still avoid it based on things they have heard that are simply not accurate. Here are the five most common myths, and the reality behind each one.

Myth 1: Cost Segregation Is Only for Commercial Properties

This is the most persistent myth, and it has probably cost residential investors more collectively than any other misconception.

Cost segregation works on any depreciable real property, including residential rentals. Single-family homes, condos, duplexes, short-term rentals, and small multifamily properties all have personal property components, like flooring, cabinetry, and fixtures, and land improvements, like driveways and landscaping, that qualify for shorter recovery periods.

The methodology is the same whether the property is a warehouse or a three-bedroom rental house. The specific components and their values differ, but the fundamental analysis is identical. Short-term rental investors in particular tend to benefit from higher reclassification amounts because furnished properties have more 5-year personal property (furniture, electronics, kitchen equipment, decor). And for STR owners who meet the material participation and average-stay requirements, those deductions can offset W-2 income — making cost segregation even more impactful.

Myth 2: It Is an Aggressive Tax Strategy That Triggers Audits

Cost segregation is not aggressive. It is the correct application of IRS depreciation rules to a property's components. The IRS has explicitly recognized cost segregation methodology since the 1990s and publishes a detailed Cost Segregation Audit Techniques Guide outlining exactly how it should be done.

A properly prepared study with complete documentation is audit-ready and entirely defensible. Every Segonomics study includes audit protection because we stand behind the methodology. Learn more in our article on what cost segregation actually is.

Myth 3: The Depreciation Recapture Makes It Not Worth It

This one has a kernel of truth that gets taken too far. Yes, when you sell a property, depreciation recapture applies to the accelerated portion at up to 25% under Section 1250. But this does not make cost segregation a bad deal.

First, standard 27.5-year depreciation is also subject to recapture at sale. You are not escaping recapture by avoiding cost segregation; you are just delaying the deductions that get recaptured.

Second, the time value of money matters enormously. A dollar of tax savings in year one is worth more than a dollar of recapture in year fifteen. The difference, invested or used productively in the intervening years, consistently outweighs the cost of paying the recapture tax later.

Third, many investors defer both capital gains and recapture indefinitely through 1031 exchanges.

Myth 4: It Is Too Expensive for a Residential Property

Traditional cost segregation firms charge $5,000–$10,000 per study, which made the math difficult for residential rentals. But that pricing reflects the old model: physical site visits, slow turnaround, and commercial-scale overhead.

Modern flat-fee providers have changed the economics. At a fraction of the traditional cost, with no site visit and delivery in 2 business days, the ROI math now works clearly in favor of residential and short-term rental investors. Read more about when to order a study.

Myth 5: It Requires an Expensive Engineer and a Site Visit

Historically, cost segregation required a physical site visit from an engineer, which made it expensive and logistically cumbersome. This kept many residential investors from doing studies at all.

That is no longer the case. With detailed property photos, public records, and satellite imagery, a thorough and IRS-compliant analysis can be completed remotely at a fraction of the traditional cost. The methodology is the same; the data collection is just more efficient.

At Segonomics, intake takes about five minutes and reports are delivered within 2 business days. No appointments, no scheduling, no site visits. Learn exactly how the process works in our article on how a cost segregation study works.

The Common Thread

Each of these myths results in property owners either skipping cost segregation entirely or delaying it unnecessarily. In most cases, the analysis is straightforward and the economics are clearly favorable. The first step is just getting an estimate.
