Five Cost Segregation Myths, Explained

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 can apply to residential and commercial properties. The study must establish which components qualify for shorter recovery periods; flooring, built-in cabinetry, and general fixtures do not automatically qualify as personal property.

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.

Documentation helps support review, but neither a study nor audit support guarantees acceptance by a taxing authority. Our support covers methodology and documentation under the engagement terms.

Myth 3: The Depreciation Recapture Makes It Not Worth It

Recapture depends on the asset. Section 1245 property may generate ordinary-income recapture, while unrecaptured Section 1250 gain may be taxed at up to 25%. It is incorrect to apply a universal 25% cap to the accelerated portion.

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.

Earlier deductions can have value, but that value must be compared with study costs, usable losses, holding period, and expected sale taxes.

A Section 1031 exchange generally covers qualifying real property. It does not automatically defer recapture on personal property identified by the study.

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.

Standard residential studies can use a flat fee. Commercial and complex engagements need an individual scope and quote; compare their expected benefit with the fee before proceeding.

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.

Standard residential studies target two business days after complete intake and payment. Commercial and complex properties have individually agreed requirements and timelines. Learn exactly how the process works in our article on how a cost segregation study works.

The Common Thread

A useful first step is to evaluate the property and the owner’s tax position together. A study should follow that assessment, rather than an assumption that every property produces an immediate saving.
