How the math works
Annual savings = (current − target) × mill rate. Consultant = max(min, year-1 savings × pct).
($22M − $18.5M) × 1.85% = $64,750/yr × 3 = $194,250 gross − $21,368 consultant = $172,882 net.

How this calculator works
What this page estimates
This Multifamily Property Tax Appeal Calculator is built to give a quick, browser-based estimate for multifamily property tax appeal. Successful property tax appeals can drop assessment 5–25% with strong comp evidence. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the multifamily property tax appeal result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this multifamily property tax appeal estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions
Why appeal?
Mass appraisal often inaccurate at property level. Multifamily commonly over-assessed: 10-25% high in many markets. Sales comparable approach + income approach (rent + cap rate) often shows lower fair value. Filing window: typically 30-90 days after assessment notice. Skipping = paying inflated tax for next 1-3 years until next assessment. Annual appeal in some states.
Process?
Stage 1: informal review with assessor (free, 30-60 day window). Stage 2: formal hearing before board of equalization or tax board (filing fee $25-500). Stage 3: state appeals board or court (legal counsel $5-25k). 60-80% of properly-supported appeals win some reduction. Typical timeline: 6-18 months. Reduction averages: 5-15% of assessment when successful.
Consultant fees?
Property tax consultant: 25-50% of first-year savings, contingent. Typical: 33% of savings. Some have minimum fee ($1-10k). National firms: Marvin F. Poer, Ryan, Altus, RSM. Boutique local firms: similar contingent model. Annual retainer model less common (used for very large portfolios). DIY appeal possible but requires comp + income data + presentation skill.
Multi-year impact?
Reassessment cycles vary: TX annual, FL annual, CA Prop 13 limits to 2%/yr until sale, IL triennial, NY annual. One successful appeal compounds over reassessment cycle. 15% reduction on $20M assessment = $3M lower base × 1% mill = $30k/yr. Over 3-5 year cycle: $90-150k cumulative savings net of consultant. ROI: 200-500% on consultant fee typical.
