How the math works

Effective exemption reduces $1 for each $1 above threshold. Tax impact = reduction × millage/1000.

$550k − $500k = $50k over threshold. $50k − $50k = $0 effective. Phase-out $50k × 1.8% = $900 tax impact.

Frequently Asked Questions

Homestead exemption?

$25-100k exemption off assessed value for primary residence. Florida: $50k + $25k senior. Texas: $40k + senior/disability additions. Michigan: $60k. Each state's own structure. Dollar savings = exemption × millage.

Phase-out mechanics?

Some states phase out at higher property values. Some eliminate at non-primary residence status. Rental conversion of homestead triggers loss + potential rollback. Timing matters for planning.

Save on property tax?

Maintain primary residence status. Don't rent for 183+ days. Keep driver's license at address. Keep tax return address. Each state has rules — follow strictly to preserve exemption.

How often should I rerun this?

Rerun this calculator whenever inputs change materially — new rent roll data, rate moves, loan balance updates, or quarterly operating data. For active deals, monthly refresh is typical. For stabilized assets under monitoring, quarterly is fine. Treat the output as a decision tool, not a one-time answer — market conditions evolve and so should your analysis.
