概覽

AI 產生的概覽

附引用與回執的美國購屋計算器與資料:真實持有成本、可負擔性、費用、利率、頭期款補助與租買比較。

可以做什麼
  • 估算購屋完整的每月持有成本,並與貸款機構的「核准」月付額對照
  • 依收入與債務計算前端與後端 DTI 預算,以及受上限約束所對應的房價
  • 查詢各州的過戶費用與利率價差百分位分布,以及最新基準房貸利率
  • 依州別與購屋者類型尋找頭期款補助方案
  • 依 CFPB 章節與管控類別解讀貸款估算費用,並試算月付額跳升、放棄交易的壓力與租買損益兩平
  • 驗證帳本回執雜湊,確認底層資料未被竄改
適用情境
適合在考慮美國購屋時取得有來源、教育性質的數字:總持有成本、可負擔上限、過戶費用基準、補助方案、費用說明或租買比較。
執行需求
位於 candidcost.com 的遠端 streamable HTTP 端點;未宣告套件、環境變數或標頭。輸入為美元,且以美國為主(州別、CFPB HMDA、FRED 利率)。

true_cost_estimate

True Cost of Ownership Estimate

Estimate the full monthly cost of owning a home — principal & interest, property tax, insurance, PMI, HOA, and maintenance — and contrast it with the lender "approval" payment (PITI+PMI) to reveal the hidden monthly gap. Dollar inputs are US dollars; all money in the response is integer cents; rates are fixed-precision percent strings.

affordability_estimate

Affordability / DTI Estimate

Compute front-end (housing) and back-end (total debt) DTI budgets from income and debts, and the home price implied by the binding limit. Reports the standard 28/36 thresholds without ever telling the user what they "can afford". Dollar inputs are US dollars; money in the response is integer cents.

fee_benchmarks

HMDA Fee & Rate-Spread Benchmarks

Return closing-cost and rate-spread percentile distributions (p25/p50/p75 + mean) for a US state, computed from the row-level CFPB HMDA LAR for originated, first-lien, home-purchase loans. Cells with fewer than 25 records are suppressed. Dollar metrics are integer cents (…Cents); percent metrics are fixed-precision strings (…Pct). Each distribution carries a ledger receipt hash for verification.

輸入參數state必填metric

benchmark_rates

Current Benchmark Mortgage Rates

Return the latest benchmark mortgage rates (e.g. 30-year and 15-year fixed) from the Federal Reserve (FRED), each with its observation date and ledger receipt. Rates are fixed-precision percent strings.

無需輸入參數。

search_dpa_programs

Search Down Payment Assistance Programs

Find down payment assistance (DPA) programs by US state and/or buyer type. Includes national programs. Each result links to its official government source and carries a ledger receipt and last-verified date.

decode_loan_estimate_fee

Decode a Loan Estimate Fee

Classify a mortgage Loan Estimate fee by CFPB section and control class (set by lender, shoppable, third-party, government, or prepaid), with a plain-language explanation and an educational question a buyer could ask. Omit "fee" to list the full catalog.

輸入參數fee

payment_shock_estimate

Year-2 Property-Tax Payment-Shock Estimate

Estimate why a mortgage payment often jumps in year two: escrow at closing is sized from the seller's current tax bill, but the county reassesses at your purchase price, and RESPA spreads the resulting escrow shortage over 12 months. Given the purchase price, the seller's current annual tax (from the listing), a state (or county FIPS) for the reassessment rate, and insurance, returns the year-1 escrow, the year-2 ongoing escrow, the temporary catch-up peak, and the jump. Money is integer cents. This decomposes the mechanics; it is not a prediction of your specific bill.

pressure_check

Pressure Check — Walk-Away Math

Decompose the tradeoff a rushed buyer faces: the earnest money at risk by walking away versus what overpaying to "win" costs over the life of the loan. Given the earnest money at risk, the overpay amount over your walk-away price, down-payment percent, rate, and term, returns the cash and financed shares of the overpay, the extra monthly P&I, the lifetime cost of overpaying, and its ratio to the earnest money. Money is integer cents. Educational decomposition — it names the two numbers so they can be compared; it never tells the user to walk or stay.

rent_vs_buy_estimate

Rent vs. Buy Net-Cost Estimate

Compare the net cost of owning against renting over a holding period and find the break-even year. Owning nets upfront cash and recurring carrying costs against sale proceeds (appreciated value − selling costs − remaining loan); renting nets rent paid against the investment gain on the cash a buyer would tie up. Dollar inputs are US dollars; money in the response is integer cents. Appreciation, rent growth, and investment return are user-set assumptions. Tax deductions are excluded (documented simplification). Educational decomposition — it reports both net costs and the break-even year; it never says rent or buy.

verify_receipt
