California Mello-Roos CFD Tax Calculator

Project the lifetime cost of a California Mello-Roos Community Facilities District (CFD) special tax on a parcel under the Mello-Roos Community Facilities Act of 1982 (Cal. Gov. Code §§ 53311–53368.3). Walks the current-year special tax forward at the supplied annual escalator (typically 2%, set by the CFD's Rate and Method of Apportionment under § 53321(d)) across the remaining bond term, reports the nominal lifetime total and the present value at a 6% discount, expresses the special tax as an effective ad-valorem-equivalent percentage of purchase price, and combines it with the parcel's Prop 13 base property tax to surface the true first-year property-tax burden. The Mello-Roos special tax is layered on top of Cal. Const. Art. XIIIA § 1(a)'s 1% base rate cap — it does NOT count toward the 1% cap because it is a special tax, not an ad-valorem tax. Disclosure is REQUIRED at every sale under Cal. Civ. Code § 1102.6b via the separate Notice of Special Tax and Assessment Lien.

California Documentary Transfer Tax + City RPTT Calculator

Compute the two-layer California real-estate transfer tax stack — the statewide County Documentary Transfer Tax under Cal. Rev. & Tax Code § 11911 (the $0.55 / $500 = 0.11% county base) plus any city-level Real Property Transfer Tax authorized by Cal. Gov. Code § 37101 and the local charter (Cal. Const. Art. XI § 5). Models the eight most-impactful 2026 city schedules: San Francisco's 0.5%-6.0% Prop ULA mansion-tax ladder (highest in the United States at the $25M+ tier), Los Angeles's 0.45% base + 4.0% / 5.5% Measure ULA surtax, Oakland's Measure X four-tier 0%-2.5% ladder, Berkeley, San Jose's Measure E schedule, Santa Monica's Measure GS schedule, Culver City's Measure RE schedule, and the catch-all 'other California city' case where only the county 0.11% applies. Each city tier applies FLAT to the whole sale price (not marginally) and the cliff effect at $5M / $10M / $25M is dispositive.
