Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

amortization_summaryread-onlyExact month-by-month amortization: monthly payment, number of payments, final payment, total interest, total paid and the remaining balance after chosen years. Supports an interest-only period followed by amortization over the remaining term, as many DSCR loans use. Interest is rounded half up to the cent each month, like a lender schedule.
calculate_dscrread-onlyDebt service coverage ratio for a DSCR (investor) mortgage: qualifying rent / PITIA. Computes exact principal and interest with the annuity formula (monthly compounding, half-up cents) or the interest-only payment, adds tax, insurance, HOA and other housing costs per the Fannie Mae PITIA definition, and places the result in the common lender bands (1.25+, 1.00-1.24, 0.75-0.99, under 0.75) with sourced notes that minimums vary by lender. Returns JSON plus a plain summary and a dscrradar.com link.
compare_scenariosread-onlyCompares 1 to 5 financing scenarios (rate, down payment, term, interest-only) on one property: loan amount, P&I, PITIA, DSCR, lender band, rent minus PITIA and total interest over the term. Names the scenario with the highest DSCR.
max_loan_for_target_dscrread-onlySolves for the largest whole-dollar loan whose PITIA keeps the DSCR at or above a target (default 1.25), given rent, rate, term, interest-only choice, tax, insurance and HOA. Optional purchase_price and max_ltv_pct give the minimum down payment and which limit binds. Exact cents arithmetic, checked against the rounded payment.
rent_needed_for_target_dscrread-onlySolves for the smallest monthly rent (to the cent, and rounded up to whole dollars) that reaches a target DSCR (default 1.25) for a given loan, rate, term, tax, insurance, HOA and vacancy. Also returns the rent for 0.75, 1.00 and 1.25. Rounds up, never down, so the rent always meets the target.

Schemas: list_tools.
