Assessment Intelligence, Not Guesswork
The same assessment analysis methodology used by tax attorneys and professional appraisers -- accessible to every homeowner. IAAO-standard ratio studies meet modern appeal probability modeling.
Assessment Ratio Analysis
Compare your assessed value against estimated market value using IAAO methodology. Compute coefficient of dispersion (COD) to measure assessment fairness within your jurisdiction.
Comparable Sales Regression
Hedonic pricing model using sqft, lot size, bedrooms, bathrooms, year built, and condition to estimate your fair market value from recent comparable sales in your jurisdiction.
Appeal Success Probability
Logistic regression on historical appeal outcomes by jurisdiction, assessment deviation, property type, and representation status. Know your odds before you file.
Net Savings Calculator
Expected value of appeal: probability of success times expected reduction times tax rate times holding period, minus appeal costs. NPV over your ownership horizon with tax rate escalation.
Cross-Jurisdiction Comparison
Compare total property tax burden across counties and states. Normalize for assessment ratios, homestead exemptions, millage rates, and rate cap structures like Prop 13.
Relocation Tax Impact
Moving? Compare property tax burden for an equivalent home across target jurisdictions, factoring in assessment frequency, rate caps, homestead exemptions, and SALT deduction impact.
