MOST ACCOUNTANTS MISS THESE TWO TAX WRITE-OFFS — AND IT’S COSTING INVESTORS THOUSANDS

For real estate investors, taxes are often the single biggest expense—and also the greatest opportunity.

Yet according to tax strategist Toby Mathis and cost segregation expert Chris Streit, two of the most valuable write-offs in real estate are routinely missed, even by competent accountants.

The result is not just a missed opportunity, but permanent tax dollars lost forever.

Those two strategies are Partial ᴀsset Dispositions (PAD) and Qualified Improvement Property (QIP).

While they sound technical, their real-world impact is simple: faster deductions, larger write-offs, and dramatically improved cash flow.

The reason they’re missed so often is timing.

Most investors—and many accountants—think tax benefits begin and end at purchase.

You buy a property, depreciate it, maybe do a cost segregation study, and move on.

But as Chris Streit explains, the story doesn’t end when the ink dries on the closing documents.

Properties evolve.

Roofs get replaced.

HVAC systems wear out.

Interiors are modernized.

Each of those changes creates tax events that many never capture.

Let’s start with Partial ᴀsset Dispositions.

When you purchase a property, the IRS requires that the cost be depreciated over time—27.5 years for residential rentals and 39 years for commercial properties.

That initial purchase price includes everything inside the building: the roof, plumbing, electrical systems, flooring, and more.

Now imagine six years later you replace the roof.

Most investors simply capitalize the new roof and continue depreciating both the old and new roofs simultaneously.

That’s the mistake.

The old roof no longer exists, yet it’s still sitting on the depreciation schedule.

A Partial ᴀsset Disposition allows you to identify the value of the old roof, remove it from the depreciation schedule, and expense it immediately.

That write-off is permanent.

There’s no recapture.

It’s as if the IRS finally acknowledges that you threw the old roof away—and lets you deduct it.

PADs don’t apply only to roofs.

They can apply to flooring, electrical systems, plumbing, windows, and more.

The key requirement is having a cost segregation study, which breaks the building into individual components and ᴀssigns each a value.

Without that segregation, you can’t dispose of what was never identified.

This is where many accountants hesitate.

Without engineering-backed documentation, the deduction becomes risky.

With it, the deduction becomes defensible and powerful.

Then there’s Qualified Improvement Property, or QIP—a provision that many investors still don’t realize now allows 100% bonus depreciation.

QIP applies to improvements made to commercial property interiors, excluding structural elements, elevators, escalators, or building expansions.

Paint, non-structural walls, flooring, lighting, electrical upgrades, and interior remodels often qualify.

Here’s where it gets interesting for real estate investors: short-term rentals—such as Airbnbs and Vrbos—are treated as commercial property for tax purposes.

That means an investor can convert a long-term rental into a short-term rental, place it into service, and then make improvements that qualify for QIP.

Those improvements can often be written off entirely in the year they’re made.

Timing is critical.

The property must already be in service as a short-term rental before the improvements occur.

If improvements are made beforehand, they simply increase the basis and lose the bonus depreciation benefit.

For investors sitting on older rentals with little depreciation left, this can be transformative.

A property held for ten or twenty years may feel “tax exhausted,” but QIP resets the game.

A $50,000 or $100,000 renovation can become a near-immediate deduction instead of a decades-long write-off.

Commercial properties such as restaurants, H๏τels, retail centers, warehouses, and even shopping malls often benefit even more.

Streit describes cases where landlords depreciated tenant improvements over 39 years when they should have been expensed immediately under QIP.

Across large portfolios, the missed deductions can reach into the millions.

Why does this matter so much right now? Because depreciation is not just about saving money—it’s about when you save it.

Every dollar deducted today is a dollar you can reinvest, especially in an inflationary environment where holding cash becomes increasingly expensive.

The fear many investors have is audits.

But according to Streit, fewer than 0.

1% of returns are audited.

When they are, proper documentation makes audits straightforward.

Problems arise only when deductions are taken aggressively without substantiation.

The real risk, he argues, isn’t scrutiny—it’s ignorance.

PAD and QIP are not loopholes.

They are explicit provisions written into tax law to encourage reinvestment, modernization, and housing supply.

When used correctly, they reward investors for maintaining and improving properties that people live and work in.

For investors serious about scaling, these strategies are not optional—they’re foundational.

Missing them doesn’t just hurt this year’s return.

It permanently reduces lifetime wealth.

And that’s the real shock: the money you don’t deduct today is gone forever.
