Lender comparison

Choose the rung that solves the current problem without trapping the next move

Bank, B and private mortgages are not three versions of the same product. They solve different underwriting problems and carry different costs. The right comparison starts with what must be solved today and what the borrower can realistically improve next.

Three lender channels, three different risk models

A prime institutional lender typically wants the cleanest combination of verifiable income, credit, ratios and property. An alternative/B lender accepts a wider range of evidence and risk for higher pricing and often fees. A private lender can place greater weight on equity/property and transaction structure but usually at materially higher cost and shorter terms.

The channels overlap. The goal is not to move “down” the ladder. It is to use the lowest-cost channel that can responsibly complete the transaction, then move to a lower-cost channel when the limiting factor has actually improved.

Bank / B / private comparison
DimensionPrime / AAlternative / BPrivate
IncomeStandard verifiable methods; program-specific self-employed/variable incomeBroader stated-income, bank-statement and contributory methodsCan be more equity-focused but affordability and exit still matter
CreditStronger history usually expected; exceptions limitedMore tolerance for recent events depending on equity and storyCredit can be secondary to security, but serious issues affect terms and exit
RatiosMainstream policy and insured limits where applicableExtended ratios may be available by productOften not driven by standard GDS/TDS, but payment affordability is still relevant
PropertyMainstream marketability and product rulesCan accept some non-standard property within policyProperty/equity is central; lender-specific geography and security appetite matter
Rate / feesUsually lowest costHigher rate; lender/broker fees may applyHighest rate/cost; lender/legal/broker fees common
TermBroad term menuOften shorter transitional termsCommonly short term
Exit importanceNormal renewal/switch planningImportant if borrower intends to return to primeCritical—repayment or refinance must be realistic before maturity

The route should be chosen by the problem being solved

If the issue is a different but still institutionally supportable income method, moderate credit impairment, extended ratios or a property that fits an alternative program, B lending can be appropriate. If the transaction involves urgency, active arrears, a very recent event, a property/security issue or a temporary problem that institutions cannot presently accept, private capital may be necessary.

Use Lender Assessment to identify the route-changing fact rather than starting with a lender label.

Compare the full cost of moving one rung

There is no universal spread. Pricing changes by lender, property, LTV, credit, term and market. The correct method is to model the actual commitments including fees, legal/appraisal costs, payment, penalty exposure and the next refinance.

Real lender-ladder examples

Yes. HopeWell funded files include a private-to-A refinance, private-to-B bank-statement refinance, and private mortgage used as a short bridge before institutional exit. The sequence works only when the factor blocking the cheaper lender is expected to improve.

The most dangerous route is the one with no next step

A higher-cost mortgage becomes dangerous when the borrower can afford the payment only temporarily but the file has no credible path to refinance or repay. The cost of repeated renewals can consume the equity that made the original approval possible.

For any transitional mortgage, read Exit Strategy Assessment before comparing the headline rate.

A practical routing tree

Start with the reason prime lending fails. If the problem can be solved by another prime program or lender, stay in prime. If it requires a recognized alternative income/credit/ratio method and there is enough time for institutional underwriting, test B lending. If the problem is urgency, active arrears, severe recent credit, property/security, or a short-lived event institutions cannot accept, test private.

Then reverse the question: what must change to climb back toward lower-cost capital? If there is no measurable answer, the higher-cost route may be treating a symptom rather than solving the financing problem.

Lower monthly payment can coexist with higher borrowing cost

Yes. A debt-consolidation refinance can replace credit cards, car loans, tax debt and private mortgages with one secured payment, producing a large monthly cash-flow improvement even if the mortgage rate is higher than a prime bank rate. That cash-flow benefit can be economically valuable.

But reducing the monthly payment by stretching debt over a longer amortization can increase lifetime interest. Measure monthly relief, total cost and debt-free timeline separately.

Private lending changes what drives the decision

Private lenders often place much more weight on property value, mortgage ranking and equity than institutional lenders. That does not mean income and credit are irrelevant. They affect payment affordability, default probability, pricing and—most importantly—the borrower’s ability to exit into institutional financing.

A private lender may fund a borrower whom a bank cannot currently approve, but the brokerage still has to assess whether the mortgage is suitable and how it will be repaid.

Worked ladder scenario

Consider a self-employed borrower with strong business deposits but only six months of operating history, high unsecured debt and substantial home equity. Prime income history may be insufficient today. A B lender may still require more business history. A short private second mortgage could consolidate the debt while preserving the first mortgage—but only if the borrower’s business history will be long enough for a B or A refinance before maturity.

The private mortgage is justified by the time it buys to reach a specific institutional threshold, not merely by available equity.

Time can force a lender-channel change

There is no permanent speed ranking. A clean bank file can move quickly; an exception-heavy bank file can take much longer. A B lender with a complete package may be faster than prime. A private lender can sometimes close very quickly, but legal, appraisal and title work still have to be completed.

The correct question is how much underwriting remains unresolved and how much time does this lender need for this exact file?

Sometimes the best higher-cost mortgage is the one that preserves a cheap first

If the borrower has a large first mortgage at a low rate with a large break penalty, a smaller B or private second mortgage can sometimes solve a short-term need without repricing the entire first mortgage.

The comparison must include the second-mortgage rate and fees and the interest/penalty saved by preserving the first. HopeWell’s Richmond Hill secured-line case illustrates this structure.
