analyze_cash_out_refinance

Full cash-out refinance waterfall: the largest new loan the property supports across LTV, DSCR and debt-yield, then down through payoff, prepayment penalty and closing costs to net cash in hand. Includes NY CEMA savings when applicable. prepaymentPenaltyPercent is REQUIRED — omitting a penalty overstates the borrower's proceeds by its entire amount, so state 0 explicitly when there is none.

ask_cre_question

Ask a plain-English question about commercial real estate lending and get a short answer grounded in Relendi's knowledge base, with citations. For loan math prefer size_loan or run_scenario, which are exact.

calculate_metrics

Compute the standard commercial real estate underwriting metrics from raw figures: NOI, cap rate, DSCR, debt yield, LTV, LTC, operating expense ratio, break-even occupancy and yield on cost. Supply whatever you have — each metric is returned only when its inputs are present, with the formula used. Use this instead of computing CRE ratios yourself.

read-only

Argument	Type	Description
rate	number	DECIMAL (0.0725 = 7.25%), used to derive debt service
loanAmount	number
annualRevenue	number	Gross/effective annual revenue
propertyValue	number
purchasePrice	number
annualExpenses	number	Annual operating expenses (excl. debt service)
totalProjectCost	number	For LTC and yield-on-cost
amortizationYears	integer
annualDebtService	number

calculate_payment

Amortizing and interest-only payment math for a commercial loan: monthly and annual debt service, total interest over the term, and the balloon balance at maturity when the term is shorter than the amortization (the normal CRE case — a 10-year term on a 30-year schedule).

compare_loan_offers

Rank competing loan offers by true cost of capital, not headline rate. Accounts for origination, exit and other fees over the actual term, and returns an effective rate, total cost and fee burden in basis points for each — so a 'cheaper' rate with heavy fees sorts correctly.

estimate_closing_costs

Itemize commercial closing costs for a New York or Florida transaction — lender, title, government (mortgage recording tax, transfer taxes) prepaid and third-party lines. Returns every line item plus totals. For New York you MUST say whether the property is in New York City: the city's recording and transfer taxes are several times the upstate rates and one of them does not exist outside the five boroughs.

read-only

Argument	Type	Description
isNYC	boolean	REQUIRED when state is NY. True = five boroughs (NYC recording tax + Real Property Transfer Tax). False = anywhere else in New York State.
state*	string
loanAmount*	number
cemaEnabled	boolean	NY refinance only. CEMA assigns rather than discharges the existing mortgage so recording tax applies to new money only. Defaults to FALSE because it requires the existing lender's cooperation, which is not guaranteed — assuming it understates costs.
isRefinance*	boolean
interestRate	number
propertyValue*

prepare_deal

Prepare a Move this deal to Relendi link from the user's CRE scenario. Use when the user wants to keep a deal, continue in Relendi, or carry property details beyond a calculator. Include only facts the user supplied, not guessed values or calculated loan limits as a requested amount. This does not save or submit anything: the user follows the link, reviews the inputs and signs up or signs in to save a private draft. Do not include personal or account information.

run_scenario

Run what-if loan sizing across a range of assumptions: a rate ladder, an NOI sensitivity table, or the feasibility of a target loan amount against each constraint. Deterministic — same math as size_loan, swept.
