Feature & Specification Comparison
Tools & Capabilities Breakdown
Mortgage Tools by Jenny Tools (6)
diagnose_mortgage_comparison
Use this first when a user wants a Canadian mortgage renewal, extra-payment, break-or-stay or debt-consolidation comparison but has not yet given the key figures. From the facts already supplied, returns the missing ones in priority order and up to three questions to ask (balance, rate, remaining amortization, term, switching costs, lender-quoted penalty). Flags a request to borrow additional cash (cash-out refinance) as unsupported. Do not use when the figures are already supplied: call the matching calculator. Does not calculate, rank, check qualification or search rates.
compare_renewal_offers
Use this when a user has two or three Canadian mortgage offers for the same balance, such as a renewal letter from the current lender and a quote to switch lender at renewal, and wants them compared. Compares the user-supplied rates, terms, amortizations, cashback and switching costs over a common horizon. Returns payments, interest, debt left, modeled borrowing cost and missing facts. Do not use for leaving a mortgage before the term ends (use compare_break_or_stay). Does not search or predict rates, confirm qualification or recommend a lender. An unknown cost is never treated as zero.
plan_mortgage_prepayments
Use this when a user asks what paying extra on one Canadian mortgage would do: a higher regular payment, recurring extra payments, or up to 50 lump sums. Compares the supplied mortgage with and without the extras: interest, debt left and modeled payoff period. Checks the extras against prepayment-privilege limits only when the user supplies them; otherwise reports the limits as not checked. Do not use to find a prepayment penalty or the cost of breaking a mortgage: no tool calculates a penalty, the lender quotes it. Results beyond the term need explicit monthly continuation assumptions.
