Deal numbers
What you're paying for the property.
Loan-to-value — loan ÷ value. E.g. 25% down = 75% LTV.
Your loan interest rate. Estimate is fine.
Expected gross rent per month.
Property taxes per year.
Homeowners insurance per year.
HOA dues per month. Enter 0 if none.
Ownership and sale assumptions
How long you plan to own the property before selling. The model runs schedules to 50 years.
Estimated land value as a percent of purchase price. Land is not depreciable — lower land % = larger depreciation deduction. Typical range: 15%–30%.
A fee some loans charge if you pay the loan off or refinance early. Expressed as % of loan balance. Enter 0 if your loan has no prepayment penalty.
Personal tax situation
Modified adjusted gross income. Determines whether passive-loss rules limit your deductions and whether NIIT (3.8% extra tax) applies.
Your state income tax rate. Enter 0 for states with no income tax (TX, FL, etc.).
Filing Status
Eligibility rules for these choices

Real estate professional status (750hr test + 50% of work time in real estate) — status alone is not enough. With material participation in the rental as well (the box that appears below), the rental's losses become deductible against ordinary income and its sale gain stays out of the 3.8% NIIT. If you don't meet both tests, leave this unchecked.

Material participation in this rental (500+ hours a year on this property's rental activity) — for a real estate professional, this is what makes the rental's losses non-passive (Treas. Reg. §1.469-9(e)(1)) and keeps its sale gain out of the 3.8% NIIT (Treas. Reg. §1.1411-4(g)(7)). Leave unchecked unless you can document the hours.

Short-term rental with material participation (average guest stay of 7 days or less) — such a rental is not a "rental activity" under §469 (Treas. Reg. §1.469-1T(e)(3)(ii)(A)), so if you materially participate its losses are non-passive, as for a real estate professional. Leave unchecked for a long-term rental.

Active participation — you own at least 10% and take part in management decisions such as approving tenants, rents and repairs. The up-to-$25,000 passive-loss allowance requires it (§469(i)(6)). Uncheck if someone else makes those decisions without you.

Lived apart all year — married filing separately, you and your spouse lived apart for the entire tax year. Only then is a passive-loss allowance available (up to $12,500, phasing out above $50,000 MAGI); otherwise it is $0 (§469(i)(5)).

How to read your return

After-tax IRR of 6.2% is acceptable but the -1.7 pts tax drag is meaningful. The depreciation shield is built on the building, not the land — a cost-segregation study accelerates it, and a land allocation on the low end of what your assessor ratio or appraisal actually supports leaves more basis to depreciate.

These layers build the year-one cash flow the 6.2% after-tax IRR above is solved from. Bars are sized against gross scheduled rent. The three tax-ledger lines — the principal add-back, depreciation, and taxable income — are marked: they change what you are taxed on, not what lands in the account, which is why the cash running total picks back up at pre-tax cash flow. Principal is added back because it is real money out but is never a deduction, so without it the rows above would not reach taxable income.

Tax calculation details

Each line is a component of the calculation, not a verdict on its own — the after-tax IRR above is the number that judges the deal. The difference between pre-tax and after-tax IRR is your total tax drag.

Depreciation deduction, whole hold — the total amount of building value you write off over the years you own it. This is the deduction, not the cash you save: your saving is roughly this figure times your tax rate.$123,636
Depreciation shield as % of NOI — annual depreciation deduction divided by net operating income44.0%
Effective tax rate (combined federal + state) — blended rate across all operating years0.0%
Total tax on exit — depreciation recapture + capital gains tax owed when you sell$36,723
§1250 recapture rate — the tax rate on depreciation you claimed (capped at 25%)23.5%
Long-term capital gains rate — applied to the remaining profit above your basis18.8%
NIIT (3.8% net investment income tax) — applies if MAGI exceeds $200K single / $250K jointYes — adds 3.8% to investment income
Compare cash flow year by year
Year-by-year cash flow — before and after taxes

Pre-Tax = net operating income minus debt service. Dep. = depreciation deduction (reduces your taxable income each year). Tax Shield = value of dep. deduction (dep. × effective tax rate). Fed+St Tax = federal plus state tax owed. After-Tax = what you actually keep. Green = positive; red = negative cash flow that year.

Cost segregation and bonus depreciation

The depreciation shield, and what the 2025 tax law changed.

The depreciation shield is built on the building, not the land. A cost-segregation study accelerates it by moving parts of the building into shorter depreciation lives, and the 2025 tax law (OBBBA) changed the bonus depreciation that can apply to those parts. This estimate depreciates the building straight-line and does not include a cost-segregation study.

Tax-law changes and real estate models: questions to verify — then confirm with a tax advisor.

Tax rules and model limits

The sections of the tax code this estimate applies, and what it leaves out.

Tax rules applied: IRC §167 straight-line depreciation over 27.5 years · §469 passive-activity-loss rules (a $25K allowance for an actively participating owner, phased out between $100K and $150K MAGI — $12.5K for a married-filing-separately filer who lived apart all year, $0 otherwise; losses beyond it are suspended and carried forward, unless you qualify as a real estate professional and materially participate in the rental, or materially participate in a short-term rental) · §1250 recapture at your ordinary rate, capped at 25%, on depreciation claimed · §1(h) long-term capital gains rates · §1411 net investment income tax 3.8% (not on the sale gain of a real estate professional who materially participates in the rental) · 2026 brackets, capital-gain thresholds and standard deduction from IRS Rev. Proc. 2025-32.

Tax figures are estimates dependent on investor federal bracket, MAGI, REP status, filing status, entity type, state tax law, and cost segregation election. Confirm with a CPA before any financing or disposition decision.
