Overview

AI-generated overview

Cited, receipt-backed US home-buying calculators and data: true cost of ownership, affordability, fees, rates, DPA programs and rent vs. buy.

What you can do
  • Estimate the full monthly cost of owning a home and compare it with the lender's approval payment
  • Compute front-end and back-end DTI budgets and the home price implied by the binding limit
  • Look up closing-cost and rate-spread percentiles by state, plus latest benchmark mortgage rates
  • Find down payment assistance programs by state and buyer type
  • Decode Loan Estimate fees by CFPB section and control class, and model payment shock, walk-away pressure and rent vs. buy break-even
  • Verify a ledger receipt hash to confirm the underlying data has not been altered
When to use it
Useful when someone is weighing a US home purchase and wants sourced, educational numbers: total ownership cost, affordability limits, closing-cost benchmarks, assistance programs, fee explanations or a rent-versus-buy comparison.
Requirements
Remote streamable HTTP endpoint at candidcost.com; no packages, environment variables or headers declared. Inputs are US dollars and US-specific (state, CFPB HMDA, FRED rates).
Before you install
Education-only, not financial advice; results are estimates, not approvals or quotes. Some tools take personal financial figures such as income, debts, purchase price and earnest money, which are sent to the remote service. Fee and program data are sourced from public datasets and may lag current conditions.

Installation

In SourceWeft

  1. Open Candidcost in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.candidcost%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.

Parametersstaterequiredmetric

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.

Takes no parameters.

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.

Parametersbuyerstate

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.

Parametersfee

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.
