The real estate market that once felt unstoppable has hit a wall. Across virtually every segment, multifamily, long-term rentals, short-term rentals, single-family purchases, and large-scale development, owners and investors are feeling the squeeze. Higher interest rates, softening rents, rising operating costs, and economic uncertainty have reshaped the landscape almost overnight.
But for those who own or are considering income-producing residential properties, there’s a proven tax strategy that can meaningfully offset the pressure: cost segregation.
Let’s set the stage first.
Multifamily: The Demand Is There, the Math Isn’t
Multifamily was the darling of real estate investment for the better part of a decade. But the same factors that once made it attractive, rising rents, strong occupancy, and cheap debt, have either reversed or evaporated. Cap rates compressed to historic lows just as borrowing costs shot up, leaving many investors holding properties that barely pencil out or, in some cases, don’t.
New supply is flooding markets like Austin, Phoenix, and Nashville, cities that overbuilt during the boom. The result? Concessions are back. Free months, waived deposits, gift cards. Effective rents are falling even as asking rents stay nominally stable, and that gap is eating into NOI.
Owners who refinanced at peak valuations are now facing a reckoning at maturity. And those looking to sell are finding a bid-ask spread wide enough to stall the entire transaction market.
Long-Term Rentals: Margin Compression Is Real
Single-family and small multifamily rental owners, the “mom and pop” landlords who make up the backbone of the rental market, aren’t faring much better. Insurance premiums have skyrocketed, particularly in the Sun Belt and coastal markets. Property taxes are catching up to inflated 2021–2022 assessments. Maintenance costs have followed inflation up and haven’t come back down.
Meanwhile, rent growth that once averaged 10–15% annually has fallen to low single digits in most markets, and in some metros rents are declining outright. The tenant who once tolerated a rent hike because they couldn’t afford to move is now pushing back, or moving.
For investors who leveraged up expecting continued appreciation and rent growth, the monthly cash flow that was supposed to justify the deal is now thin, or gone.
Short-Term Rentals: The Airbnb Gold Rush Is Over
The short-term rental market had its moment in the sun during the post-COVID travel boom. Revenue per available rental shot up, and investors piled in, often paying prices that only made sense at peak occupancy rates.
That environment is gone. Occupancy rates have normalized. Supply in popular markets has exploded. At the same time, municipalities across the country have tightened regulations, imposed permit caps, or outright banned new short-term rentals in residential zones. Platforms like Airbnb and Vrbo are more crowded, and the race to the bottom on nightly rates in competitive markets has accelerated.
Operators who were clearing strong margins in 2021 and 2022 are now fighting to cover their mortgages, especially those who bought at the top.
Home Purchases: Buyers Sitting on the Sidelines
The for-sale market is in a peculiar stalemate. Would-be buyers are priced out or unwilling to trade a 3% mortgage for a 7% one. Sellers with locked-in low rates have no incentive to list. Inventory remains thin, prices have held stubbornly high in most markets despite eroded affordability, and transaction volume is near multi-decade lows in some regions.
First-time buyers are waiting. Move-up buyers are waiting. Investors are waiting. Everyone is waiting for rates to drop, and rates aren’t dropping fast enough.
Large Developments: The Projects That Won’t Get Built
At the institutional level, the pullback is even more pronounced. Ground-up development, multifamily, mixed-use, and build-to-rent, has slowed dramatically. Construction costs remain elevated. Financing is expensive and harder to secure. Pre-leasing targets that once gave lenders comfort are harder to hit in oversupplied markets. Many projects that made sense on a 2021 proforma simply don’t work today.
Permitting activity is down. Groundbreakings are down. And the developers who pushed forward on projects started at the peak are now delivering into a softer market with debt service that assumed a better environment.
So What Can Property Owners Actually Do?
You can’t control interest rates. You can’t manufacture tenants or force appreciation. But you can control your tax position, and for income-producing residential property owners, that’s where a real opportunity exists.
Cost segregation is one of the most powerful and underutilized tools available to real estate investors, and in a compressed-margin environment, it matters more than ever.
How Cost Segregation Works and Why It Matters Right Now
When you purchase or construct a residential income property, the IRS requires you to depreciate the building itself over 27.5 years. That’s a long, slow tax benefit, useful, but not optimized.
A cost segregation study changes that. Performed by engineers and tax professionals, the study breaks your property down component by component, identifying assets like flooring, cabinetry, specialty wiring, landscaping, land improvements, and other elements that qualify for much shorter depreciation lives of 5, 7, or 15 years.
The result is a significant acceleration of depreciation deductions into the early years of ownership, when you need cash flow most.
For example, a property purchased for $1.5 million might have $300,000 or more in components that can be reclassified and depreciated rapidly. In an environment where bonus depreciation is still available for qualified property, a meaningful portion of that could flow through to your return in year one. For an investor squeezed by rising expenses and softening rents, that kind of tax offset is real money.
It’s Not Just for New Purchases
One of the most common misconceptions about cost segregation is that it only applies to properties you just bought. That’s not the case.
If you’ve owned a residential rental property for years and never had a cost segregation study performed, you can still capture those missed deductions. A look-back or catch-up study allows you to claim the cumulative depreciation you could have taken in prior years, all in a single year, without amending previous returns. It’s a straightforward process that has put meaningful refunds and tax savings in the hands of property owners who didn’t even know they were leaving money on the table.
Who Should Be Looking at This?
If you own or are planning to purchase an income-producing residential property, a rental home, a small multifamily building, a vacation rental, or a larger residential investment, and the purchase or construction cost was $500,000 or more, a cost segregation study is worth exploring.
It’s especially timely now, when cash flow is under pressure and every dollar of tax savings has real impact, when bonus depreciation provisions still allow for significant first-year deductions on qualifying assets, and when property values have moderated, giving investors who buy today a strong opportunity to structure ownership efficiently from day one.
The CSSI Difference
Not all cost segregation studies are created equal. The quality of the study, and its ability to hold up under IRS scrutiny, depends entirely on the methodology and experience behind it.
CSSI has been performing engineering-based cost segregation studies for over 23 years, with more than 65,000 completed studies across the country. Our approach is grounded in detailed, site-specific analysis rather than estimates or software shortcuts. Every study is built to be defensible, designed to deliver maximum legitimate benefit without inviting audit risk or future disallowance.
In a market environment where every dollar matters and risk tolerance is lower, working with a firm that prioritizes accuracy and compliance isn’t just smart, it’s essential.
The Bottom Line
The housing market is in a difficult period, and there’s no simple fix for rising costs, compressed margins, or a frozen transaction market. But property owners who take a proactive approach to their tax strategy can meaningfully improve their financial position, even in a down cycle.
Cost segregation won’t solve every challenge, but for the right property and the right owner, it can generate tens or even hundreds of thousands of dollars in accelerated deductions. In a market where cash flow is king and every advantage counts, that’s not a small thing.
If you own or are considering an income-producing residential property, a no-cost analysis from CSSI can show you exactly what’s on the table, with no obligation and no guesswork.
