Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
rates
get_rates
Today's indicative rate for every commercial mortgage program that has a published spread: the live index (Treasury, SOFR or prime, with its date) plus the program's spread range from a named, dated source, lowest first. Filter by property type, purpose or program family. Programs with no public spread are listed as such instead of guessed.
get_rates_by_lender_type
Indicative commercial mortgage rate ranges for banks, life companies, CMBS, agency and debt funds: each lender type's index today (Treasury or 30-day SOFR, with its date) plus its spread range from a named, dated public source. Banks have no public spread source, so no range is given for them.
compare
compare_programs
Two or three commercial mortgage programs side by side: today's indicative rate, loan size range, maximum LTV and LTC, minimum DSCR and debt yield, term, amortization, rate type, recourse, prepayment and timeline, each figure dated and sourced, plus the site's head-to-head comparison page when one exists.
index
get_index_rates
The latest 5-, 7- and 10-year Treasury yields, overnight and 30-day average SOFR, and the bank prime rate that commercial mortgages price from, each with its observation date, the value a week earlier, the change in basis points and its publisher.
match
match_programs
Rank the commercial mortgage programs (agency, FHA/HUD, bank, credit union, life company, CMBS, bridge, debt fund, DSCR, construction and more) that fit a deal, with the reasons and cautions for each, today's indicative rate (live index plus the program's published spread), and an estimate of the largest loan each program's published LTV/LTC, DSCR and debt-yield limits allow. Programs that do not fit are listed with the reason. Same rules as the site's /find-your-loan/ matcher.
prepayment
prepayment_estimate
Estimate the prepayment premium on a commercial mortgage: Fannie Mae-style yield maintenance (Form 6104.01, annual discounting), Freddie Mac yield maintenance (monthly), CMBS yield maintenance, a defeasance cost estimate, a Fannie Mae declining (step-down) schedule, or an SBA 504 debenture premium. Treasury yields default to today's readings, interpolated to the time left. Same math as the site's prepayment calculator; schedules and minimums come from the verified loan-document facts.
program
program_rules
Everything published about one commercial mortgage program: eligible property types and loan purposes, minimum and maximum loan, maximum LTV and LTC, minimum DSCR and debt yield, term, amortization, rate type, recourse, prepayment, timeline, today's indicative rate, who it fits and who should look elsewhere, and the programs to compare it with. Every figure carries its as-of date and primary source (Fannie Mae, Freddie Mac, HUD, SBA, eCFR, SEC filings and others). Limits that are not published say so.
size
size_loan
The largest commercial mortgage a property supports under a lender type's loan-to-value, DSCR and debt-yield limits, which test binds, the monthly payment, and the resulting LTV, DSCR, debt yield and cap rate. Same math and defaults as the site's loan sizer; omit lender_type to size the deal under all five lender types.
spreads
get_spreads_by_property_type
Permanent-loan spreads over the 10-year Treasury by property type (multifamily, industrial, retail, office) on 60 to 65% LTV loans, from CRED iQ as of March 31, 2026, plus the indicative rate at today's 10-year yield. Hotel, self storage, medical office and mixed use have no public source and say so.
