What Are EBIT and EBITDA? Understanding the Fundamentals

For real estate investors, understanding EBIT and EBITDA starts with recognizing their calculation differences. EBIT represents your property’s operating income after deducting all operating expenses, but before interest and tax payments. Think of it as the pure operating profit your rental property generates each month.

EBITDA expands this concept by adding back depreciation and amortization. Depreciation is the non-cash deduction you claim on your tax return each year as your building slowly loses value. Amortization spreads loan origination costs over time. By adding these back, EBITDA attempts to show what your business would look like without \”accounting adjustments.\”

The Simple Calculation Method

Here’s how the math works for a typical rental property with $120,000 in annual rental income:

• Gross Rental Income: $120,000
• Minus Operating Expenses (insurance, maintenance, property tax): -$35,000
• Equals EBITDA (before depreciation): $85,000
• Minus Depreciation Deduction: -$18,000
• Equals EBIT (operating profit): $67,000

This simple example shows why EBITDA appears higher than EBIT. Yet depreciation represents a real economic cost: your building ages and eventually requires replacement. Lenders often use EBITDA to assess loan capacity, but savvy investors know this metric masks important realities.

Why Real Estate Investors Must Know These Metrics

Lenders and investors frequently compare properties using EBITDA multiples. A property with $85,000 EBITDA might be valued at $425,000 (5x multiple). However, if depreciation is understated or future capital expenditures are ignored, the actual cash available to investors drops significantly.

How Section 163(j) Limits Your Interest Deductions

Section 163(j) represents one of the most important tax limitations real estate investors face. This IRS rule directly reduces your tax deductions if you carry high levels of mortgage debt. Understanding how this limitation works is critical for debt structuring decisions.

For 2025, the IRS allows you to deduct interest expense equal to 30% of your adjusted taxable income, which approximates EBITDA. If your interest payments exceed this 30% threshold, the excess amount cannot be deducted in the current year. Instead, it carries forward indefinitely until future years when your income is higher relative to interest expense.

Real-World Section 163(j) Calculation Example

Consider a real estate investor who owns a $2 million apartment complex financed with a $1.5 million loan at 6% interest:

• Annual Interest Expense: $90,000 ($1.5M × 6%)
• Adjusted Taxable Income (EBITDA): $150,000
• 30% of EBITDA Limitation: $45,000
• Deductible Interest in 2025: $45,000
• Excess Interest Carried Forward: $45,000

In this scenario, the investor loses $45,000 in tax deductions during 2025. This amount carries forward to 2026 and beyond. If income increases next year, or interest expense decreases, some of this carryover becomes deductible.

How to Calculate Your 30% Limitation Threshold

Calculating your Section 163(j) limitation requires identifying your adjusted taxable income. For real estate businesses, this generally equals EBITDA. Take your gross rental income, subtract operating expenses (property tax, insurance, maintenance, utilities), and subtract depreciation.

Why EBITDA Can Overstate Real Estate Earnings

Real estate investors often fall into a dangerous trap: accepting EBITDA as the primary measure of profitability. This metric became popular in corporate finance where businesses have minimal depreciation. But real estate is fundamentally different. Buildings decay. Roofs need replacing. HVAC systems fail. EBITDA ignores all of this.

A property generating $85,000 in EBITDA might have $18,000 in depreciation, $12,000 in roof reserves for eventual replacement, and $8,000 in HVAC maintenance costs. The true economic profit available to the owner is far lower than EBITDA suggests.

The Aggressive EBITDA Adjustment Problem

In competitive lending environments, some lenders enable property sellers to make aggressive EBITDA adjustments. They add back expenses that management claims are \”non-recurring\” or \”one-time.\” While some adjustments are legitimate (one-time lawsuit settlements), others obscure ongoing reality.

A landlord might add back $25,000 in \”one-time\” painting costs, claiming they won’t recur. Yet every five years, the entire property requires repainting. This is not a one-time expense—it’s a recurring capital expenditure that EBITDA adjustments conveniently ignore.

Expense Category	Included in EBITDA?	Real Reality for Real Estate
Depreciation	No (added back)	Buildings truly decline; replacements required
Capital Expenditures	No	Roofs, HVAC, plumbing must be replaced regularly
Vacancy Factor	Sometimes ignored	Real properties experience turnover and vacancy periods
Interest Expense	No (it’s in EBIT)	Debt service is a real cash outflow that reduces owner equity

Valuation Risk from Overrelying on EBITDA

When investors or lenders overpay based on inflated EBITDA multiples, properties fail to deliver promised returns. An investor might purchase a \”5x EBITDA\” property expecting strong cash flow, only to discover that actual maintenance costs consume half the profit.

This is precisely why real estate investor tax strategies must include comprehensive financial analysis beyond simple EBITDA metrics.

FFO and AFFO: Better Metrics for Real Estate Analysis

Professional real estate investors and REITs rely on Funds From Operations (FFO) and Adjusted Funds From Operations (AFFO) because these metrics address EBITDA’s fatal flaws. FFO starts with net income and adds back the depreciation that was deducted. This reveals cash available from operations more accurately than EBITDA.

AFFO goes further. It subtracts capital expenditures (the real cash you spend replacing roofs and HVAC systems) and other adjustments. AFFO shows what cash is truly available for distribution to owners after maintaining the property in proper condition.

FFO vs AFFO: Practical Example for Your Analysis

Using our $2 million apartment complex example, let’s calculate both metrics:

• Gross Income: $120,000
• Operating Expenses: -$35,000
• Interest Expense: -$45,000
• Depreciation: -$18,000
• Net Income: $22,000
• Add Back Depreciation: +$18,000
• FFO: $40,000
• Subtract Capital Expenditures (roof, HVAC): -$12,000
• AFFO: $28,000

Notice the dramatic difference. While EBITDA was $85,000, actual funds available for you after maintaining the property is only $28,000. That’s a 67% reduction. This reveals why EBITDA multiples can be dangerously misleading.

Maximizing Depreciation While Managing EBITDA Limitations

For 2025, the IRS extended significant depreciation benefits for real estate investors. Bonus depreciation at 100% is available for depreciable assets placed in service after January 19, 2025. This means you can immediately write off the full cost of eligible property improvements, dramatically reducing your tax liability in the year acquired.

However, aggressive depreciation strategies require careful coordination with Section 163(j) limitations. By accelerating depreciation deductions, you reduce your current-year EBITDA, which simultaneously reduces your Section 163(j) interest deduction limit. This creates a tradeoff: more depreciation deductions today mean fewer interest deductions available.

Cost Segregation: Unlocking Hidden Depreciation

Cost segregation studies identify components of your property that depreciate faster than the standard 27.5-year residential or 39-year commercial timeframe. Parking lots, landscaping, certain equipment, and tenant improvements often depreciate over 5 or 15 years instead.

A $1 million property might generate $25,000 in regular depreciation annually. A cost segregation study could identify $150,000 in assets qualifying for 5-year depreciation, generating additional $30,000 annually in accelerated deductions. Combined with 100% bonus depreciation available in 2025, you could eliminate years of tax liability.

Section 179 Deductions: $2.5 Million for 2025

The Section 179 deduction limit increased to $2.5 million for 2025 (doubled from prior years). This allows real estate businesses to immediately deduct the cost of qualifying equipment and improvements, rather than depreciating them over multiple years.

For a rental property owner, qualified Section 179 property might include appliances, flooring, fixtures, or outdoor equipment. Taking the full $2.5 million Section 179 deduction in 2025 could eliminate taxable income for multiple years, deferring tax liability.

Smart Debt Structuring to Navigate EBITDA Limitations

Real estate investors with high-leverage portfolios must structure debt strategically to avoid exceeding Section 163(j) limitations. This requires coordinating interest-bearing debt with income generation, understanding carryforward rules, and timing property acquisitions.

Multi-Entity Structuring: Segregating Properties

Section 163(j) applies on an aggregate basis to all businesses you own. However, holding properties through separate entities—LLCs taxed as S-Corps, for example—can optimize your overall limitation. High-income properties can fund interest deductions for leverage-heavy properties.

An investor with a stabilized office building generating $200,000 EBITDA and modest debt might have substantial unused Section 163(j) capacity. By separating this property from a highly-leveraged development project, the office building’s excess deduction capacity remains available.

Timing Strategies: Strategic Acquisition Sequencing

When acquiring multiple properties, timing matters. If purchasing a stabilized property with high EBITDA in 2025, you increase your Section 163(j) capacity for the entire year. Acquiring a development property or value-add deal later improves your interest deduction availability.

Additionally, timing large renovations and depreciation recapture can influence EBITDA in specific years, optimizing your overall tax position across a multiple-year investment plan.

Uncle Kam in Action: Real Estate Investor Saves $28,500 Annually

Client Snapshot: Marcus, a real estate investor managing a portfolio of five rental properties totaling $4.2 million in value, was using simple EBITDA analysis to evaluate new acquisitions. He tracked gross income and operating expenses but ignored depreciation, capital requirements, and Section 163(j) limitations in his decision-making.

Financial Profile: Annual rental income across the portfolio: $420,000. Outstanding mortgage debt: $2.4 million at average 5.5% interest rate. Existing taxable income: $85,000 annually before considering tax-planning strategies.

The Challenge: Marcus had identified an $800,000 apartment building with $95,000 in EBITDA (looking like a great 8.4x multiple). His broker assured him this was a \”cash flowing\” deal. However, Marcus was losing $28,000 annually to interest expense limitations under Section 163(j). He didn’t understand why his additional income wasn’t fully deductible despite high mortgage debt. Moreover, he was missing depreciation planning opportunities that could offset his rental income.

The Uncle Kam Solution: We implemented a comprehensive EBIT vs EBITDA limitation analysis using FFO and AFFO metrics. First, we recalculated his existing portfolio using AFFO, revealing that capital expenditure reserves and maintenance costs reduced distributable cash by 35% compared to EBITDA. This informed his acquisition decision.

Second, we performed a cost segregation study on his five existing properties, identifying $420,000 in assets eligible for accelerated 5-year depreciation. Combined with 100% bonus depreciation available in 2025 for any new improvements, we generated $62,000 in additional depreciation deductions for 2025.

Third, we restructured his debt across his properties, optimizing which mortgages belonged in separate entities to maximize Section 163(j) capacity. By doing this, he recovered $28,000 of the previously-disallowed interest deductions and eliminated his entire tax liability for 2025.

We advised Marcus to pass on the $800,000 building (which lacked the FFO quality he needed) and instead focus on a $950,000 stabilized property generating $110,000 EBITDA with $65,000 in proven AFFO. This strategic alternative acquisition positioned him better long-term.

The Results:

• Tax Savings: $28,500 in recovered interest deductions and $18,700 from accelerated depreciation = $47,200 annual federal tax savings (at combined 37% rate)
• Investment: $8,500 one-time cost for cost segregation study and financial restructuring
• Return on Investment: 5.5x return in the first year alone, plus multi-year depreciation benefits and ongoing structural optimization

This is just one example of how our proven tax strategies have helped clients achieve significant savings and financial optimization while managing EBIT vs EBITDA limitation rules effectively.

Frequently Asked Questions

What happens to interest deductions that exceed the 30% EBITDA limitation?

Excess interest that exceeds your 30% Section 163(j) limitation does not disappear—it carries forward indefinitely to future tax years. If your income increases or interest expense decreases in a future year, you can deduct carried-forward interest. This creates a valuable asset that many investors overlook when evaluating their tax positions.

Can I avoid Section 163(j) limitations through entity structuring?

While you cannot fully eliminate Section 163(j), strategic multi-entity structuring can optimize your overall limitation. Holding different properties through separate entities, especially when combined with S-Corp elections, can segregate high-income operations from leverage-heavy ones, preserving unused deduction capacity where needed most.

Should I prioritize depreciation deductions over maintaining lower debt?

This depends entirely on your specific situation. If you have substantial taxable income from other sources and limited debt, aggressive depreciation deductions reduce your overall liability. If you have carried-forward interest deductions, preserving EBITDA capacity might be more valuable. Professional analysis of your complete financial picture is essential.

Does the 100% bonus depreciation for 2025 apply to all real estate improvements?

Bonus depreciation applies to qualifying depreciable property placed in service after January 19, 2025. This includes equipment, fixtures, and certain structural improvements, but not the building itself. Cost segregation studies maximize bonus depreciation by identifying component assets that qualify. Consulting a tax professional ensures you’re capturing all available opportunities.

What is \”real estate professional\” status and how does it affect EBIT vs EBITDA limitations?

Real estate professional status under Section 469 exempts qualified investors from passive activity loss limitations and, importantly, from Section 163(j) interest deduction limitations. To qualify, you must spend more than half your professional time in real estate activities and more than 750 hours annually. This status transforms your tax position dramatically but requires careful documentation and substantiation.

How do I know if I should refinance to take advantage of lower rates while managing EBITDA limitations?

Refinancing reduces your monthly interest expense and also reduces your Section 163(j) limitation in future years. Lower interest payments mean less carried-forward excess interest. However, you must also consider refinance costs and the timing of when you’ll need deduction capacity. A comprehensive analysis comparing your current position to projected future income is critical.

Are there any alternatives to traditional depreciation for real estate tax planning in 2025?

Beyond standard depreciation and cost segregation, opportunities include opportunity zone investments (which defer and reduce capital gains), 1031 exchanges (which defer gain recognition entirely), and cost basis step-up strategies through estate planning. Each requires careful analysis but can provide substantial additional tax benefits.
