概览

AI 生成的概览

有引用与回执的美国购房计算器与数据:真实持有成本、可负担性、费用、利率、首付援助和租买对比。

可以做什么
  • 估算购房的完整月度持有成本,并与贷款机构的“批准”月供对比
  • 按收入与债务计算前端和后端 DTI 预算,以及受约束上限对应的房价
  • 查询各州过户费用与利率价差的百分位分布,以及最新基准房贷利率
  • 按州和购房者类型查找首付援助项目
  • 按 CFPB 章节与管控类别解读贷款估算费用,并测算月供跳涨、放弃交易压力与租买盈亏平衡
  • 校验账本回执哈希,确认底层数据未被篡改
适用场景
适合在考虑美国购房时获取有来源、教育性质的数字:总持有成本、可负担上限、过户费用基准、援助项目、费用解释或租买对比。
运行要求
位于 candidcost.com 的远程 streamable HTTP 端点;未声明软件包、环境变量或请求头。输入为美元,且面向美国(州、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.

输入参数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.

无需输入参数。

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.

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

Verify a Data Receipt

Verify a CandidCost ledger receipt hash (full sha256 or short "3f9a…c21e" form). Confirms the receipt exists and that its dataset hash chain is intact, proving the underlying data has not been altered since ingestion.
