Cal. Civ. Code § 1950.5 (security for rental of residential property)

California Tenant Security Deposit Calculator

Evaluate a California residential security deposit under Cal. Civil Code § 1950.5, as amended by AB 12 (Statutes of 2023, Ch. 689; effective July 1, 2024). Computes the lawful maximum deposit under the post-AB-12 one-month cap (§ 1950.5(c)(1)), the small-landlord two-month exception for natural persons owning no more than two residential properties comprising no more than four units (§ 1950.5(c)(4)), and the active-duty servicemember one-month protection (§ 1950.5(c)(5)). Surfaces the § 1950.5(g)(1) 21-day return deadline, the § 1950.5(g)(2) itemized statement and $125 receipt threshold, the § 1950.5(f) pre-move-out walkthrough right, and the § 1950.5(l) bad-faith retention exposure of up to two times the deposit.

IRC § 121 (full section)

Federal Section 121 Primary Residence Exclusion Calculator

Compute the IRC § 121 primary-residence capital-gains exclusion — $250,000 single / $500,000 married-filing-jointly — on the sale of your principal residence, with the depreciation-recapture carve-out under § 121(d)(6), the non-qualified-use proration under § 121(b)(5), the partial-exclusion safe harbor under § 121(c), and the NIIT stack under IRC § 1411. Surfaces the realized gain, eligibility-test status, effective exclusion, taxable gain, depreciation-recapture liability, and the NIIT-subject base in a single planning view. Federal-pure mechanics: applies in any jurisdiction.

F.S. § 201.02

Florida Mortgage Calculator

Compute the real cost of a Florida home — not just the principal-and-interest payment. Layers in property tax under F.S. § 200.001, hurricane-loaded homeowners insurance under F.S. § 627.4133, HOA dues, and the Florida-specific closing-cost stack other mortgage calculators miss: deed documentary stamps (F.S. § 201.02), mortgage documentary stamps (F.S. § 201.08), the non-recurring intangible tax (F.S. § 199.133), and OIR-promulgated title insurance (F.S. § 627.7825). Surfaces cash to close, monthly all-in (PITI + HOA), affordability against the 28/36 rule, and total cost of ownership over the full loan term.

F.S. § 201.08 (mortgage documentary stamp)

Florida Mortgage Refinance Break-Even Calculator

Compute the break-even month on a Florida mortgage refinance — the point at which monthly P&I savings recoup the new note's closing costs. Florida-specific because every Florida refi triggers a fresh round of the mortgage-side closing-cost stack other states do not impose: documentary stamps on the new mortgage under F.S. § 201.08 ($0.35/$100), the non-recurring intangible tax under F.S. § 199.133 ($2 per $1,000), and a new lender's title insurance policy under F.S. § 627.7825 / OIR Rule 69O-186.003. The standalone lender's policy on a refi is NOT eligible for the simultaneous-issue $25 flat rate; it is rated at the full promulgated schedule on the loan amount, with a 30% reissue credit available if the prior owner's policy was issued within 3 years. Surfaces monthly savings, total Florida refi closing costs, break-even month, 5- and 10-year cumulative net savings, and a refi-worth-it verdict against your expected holding period.

IRC § 121

Florida Primary Residence Capital Gains Calculator

Compute the federal capital gains tax on the sale of a Florida primary residence after the IRC § 121 exclusion ($250K single / $500K MFJ). Surfaces realized gain, the § 121 exclusion applied, depreciation recapture at the flat 25% rate under IRC § 121(d)(6) and § 1250, the 3.8% Net Investment Income Tax under IRC § 1411, and the partial-exclusion proration under Treas. Reg. § 1.121-3. Florida has no state personal income tax (Florida Constitution Art. VII § 5), so the federal-only math is the entire picture.

F.S. § 201.08 (mortgage documentary stamp tax

Florida HELOC vs Home Equity Loan vs Cash-Out Refinance Calculator

Compare the three ways to tap home equity in Florida — a HELOC, a fixed-rate home equity loan, or a cash-out refinance — side by side on monthly payment, Florida statutory closing costs, and 10-year total cost. Florida-specific because the mortgage documentary stamps (F.S. § 201.08) and the non-recurring intangible tax (F.S. § 199.133) apply to each option's new lien face amount, and the math diverges sharply: the cash-out refi taxes the FULL new first lien (old balance plus cashed-out amount), not just the cash-out portion, while a HELOC or HE loan only taxes the second-lien face. Surfaces the maximum line available under the typical 85% combined-LTV cap, monthly payment shape for each option (HELOC interest-only during the 10-year draw, HE loan fully amortizing, refi P&I), Florida-typical non-statutory closing-cost line items, 10-year cost comparison, and a recommendation based on lowest total cost and stated use of funds. Includes an IRS Pub 936 / TCJA 2017 deductibility check on the stated purpose.

24 CFR Part 206 (HECM regulations

Florida Reverse Mortgage / HECM Calculator

Compute the principal limit, available cash at closing, monthly tenure payment, and line-of-credit growth on a Florida HUD Home Equity Conversion Mortgage (HECM) — the federally-insured reverse mortgage available to homeowners age 62 and older through HUD-approved lenders. Florida-specific because the new HECM lien triggers Florida mortgage doc stamps (F.S. § 201.08) at $0.35/$100 of max claim amount plus the non-recurring intangible tax (F.S. § 199.133) at 2 mills per dollar — a meaningful add-on to the federal HECM closing-cost stack (2% Initial MIP, capped origination, counseling, third-party costs). Surfaces the HUD PLF lookup by age and expected rate, the $1,209,750 HECM national lending limit, the four HECM payment-option structures (lump sum, tenure, line of credit with growth, hybrid), and the projected balance at years 10 and 20. Includes the Florida homestead nuance: the constitutional homestead shield (Art. X § 4) does not survive a mortgage default, but HECM is structured so that non-payment cannot trigger default because payments are deferred — meaning the homestead protection remains meaningfully intact for HECM borrowers who keep current on property charges.

F.S. § 83.49 (Florida Residential Landlord and Tenant Act — security deposits)

Florida Tenant Security Deposit Recovery Calculator

Evaluate a Florida residential security deposit dispute under F.S. § 83.49 (Florida Residential Landlord and Tenant Act): holding requirements under § 83.49(1) (separate non-interest-bearing account, separate interest-bearing account at 5% or 75% of the annualized average rate, or a Florida surety bond), the 30-day disclosure of holding method under § 83.49(2), the 15-day no-claim return obligation under § 83.49(3)(a), the 30-day written-claim-notice deadline under § 83.49(3)(b) (certified mail required), and the 15-day tenant-objection window under § 83.49(3)(c). Surfaces the statutory forfeiture rule — a landlord who misses the 30-day claim-notice deadline forfeits the right to claim against the deposit by operation of statute — and computes the tenant's recoverable amount, the timeline status, and the procedural-compliance verdict.

CFPB Regulation Z / Ability-to-Repay rule (12 CFR § 1026.43)

Florida Mortgage Pre-Approval DTI Calculator

Compute front-end and back-end debt-to-income (DTI) ratios for a Florida mortgage pre-approval using the lender's PITIH housing line — principal, interest, property tax, hazard insurance, and HOA. Surfaces the 28% / 36% / 43% / 50% caps that conventional, QM, FHA, VA, and jumbo lenders apply under CFPB Regulation Z / Ability-to-Repay (12 CFR § 1026.43). Florida-specific: bakes in non-homesteaded property tax estimation, hurricane-loaded HOI defaults under F.S. § 627.4133, and the post-Surfside condo HOA reality under F.S. § 718.112(2)(g). Outputs maximum loan amount and maximum purchase price by loan type so a buyer knows exactly which programs they pre-qualify for before the lender pulls credit.

F.S. § 201.08

Florida Mortgage Doc Stamp + Intangible Tax Calculator

Compute the two distinct Florida taxes that hit at the recording of a mortgage — the $0.35-per-$100 documentary stamp tax under F.S. § 201.08 and the 2-mill non-recurring intangible tax under F.S. § 199.133. Surfaces the § 199.143 modification and new-money rules that determine which portions of a refinance, HELOC, or assumption are taxable, and which are exempt.

RCW Chapter 82.87 (Washington Long-Term Capital Gains Tax)

Washington State Capital Gains Tax Calculator

Estimate Washington's 7% long-term capital gains tax under RCW Chapter 82.87 — the stand-alone state excise enacted by SB 5096 in 2021 and upheld by the Washington Supreme Court in Quinn v. State, 200 Wn.2d 1 (2023). Washington has no state personal income tax (Article VII of the Washington Constitution); this 7% levy sits alone on long-term capital gains in excess of a $270,000-per-individual standard deduction (RCW 82.87.060, inflation-adjusted). Surfaces the broad RCW 82.87.050 exemptions (real estate, retirement accounts, qualified family-owned small business, agricultural assets meeting the 51% farming-income test, timber and timberland under the Forest Excise Tax of Chapter 84.33, commercial fishing privileges), the $100,000 qualified charitable deduction for contributions to Washington educational institutions (RCW 82.87.070), and the April 15 Form 41 0050 filing deadline.
