How US lenders underwrite a Canadian non-resident
A US lender quoting a Canadian non-resident solves for three numbers: the down payment, the qualifying ratio, and the reserves. Everything else (rate sheets, program names, marketing) is decoration on those three. The channel you pick decides how each number is computed.
Channel one: the Canadian-bank US subsidiaries. RBC Bank, BMO Bank N.A., TD Bank N.A., CIBC Bank USA and Desjardins Bank underwrite Canadians as a home franchise: they read your Canadian credit bureau, accept Canadian income documents, and need no US credit score. Typical range: entry down payments around 20 to 25 percent and pricing close to US conforming rates, with program details by bank compared in the manual's non-resident mortgage guide.
Channel two: US foreign-national lenders. Private and portfolio lenders serve any non-resident through Florida mortgage brokers. Typical range in 2026: 30 to 35 percent down, a rate premium of roughly 0.5 to 1.5 points over conforming (the 7.75 to 8.75 percent band on a 30-year fixed), 1 to 2 percent of the loan in foreign-national fees, and around 12 months of PITIA in reserves. The deep dive, channel by channel, sits in the same non-resident mortgage guide, group 2.
Channel three: DSCR. For rental property, DSCR programs qualify the building, not the borrower: gross monthly rent divided by PITIA, with 1.00 the usual floor and better pricing above 1.20. No T1s, no employment verification. Mechanics, parameters and traps are in DSCR loans for Canadians, and the refinance variant in DSCR cash-out for BRRRR investors.
Two adjacent routes complete the map: borrowing in Canada against home equity and arriving in Florida as a cash buyer (the HELOC route, weighed against US financing in cash versus financing), and the credit-building shortcuts (Nova Credit imports your Canadian file; an authorized-user card seeds a score) that move you from channel two pricing toward channel one over time.
The ratios behind the quote
US underwriting tests a debt-to-income ratio: all monthly obligations, including the new PITIA, divided by gross monthly income. Typical range: full-doc programs cap DTI near 43 to 50 percent depending on compensating factors; foreign-national files usually price assuming the conservative end. Canadian lenders test the same idea twice (GDS on housing costs, TDS on all debts) but against a stress-tested rate under OSFI's Guideline B-20: you qualify at the higher of your contract rate plus 2 points or the qualifying floor. Verified fact: B-20 is a federal Canadian guideline applying to federally regulated lenders; the US has no equivalent stress-test add-on, your quoted rate is your qualifying rate. That single difference explains why the same Canadian buyer can carry more nominal mortgage in Florida than at home on paper, and why the calculator above lets you test payment shock manually instead: re-run it at your rate plus two points and see whether the CAD payment still fits.
Reserves are the quiet third test. Typical range: foreign-national programs ask for 6 to 12 months of PITIA in liquid assets after closing; cross-border bank programs are lighter. Reserves can sit in Canadian accounts, documented and converted on paper at the prevailing rate.
The document stack a Canadian should assemble
Every channel starts from the same folder: passport; proof of Canadian address; two to three months of bank and investment statements covering down payment and reserves, with a paper trail for large transfers; Canadian credit bureau consent (channel one) or an international credit report request (channel two); income proof, either employment letter and pay statements or, for the self-employed, accountant-prepared financials and the last two T1 Notices of Assessment; and for DSCR files, the lease or a market-rent appraisal instead of income proof. Add an ITIN only where the program requires US tax identification, the application path is in the ITIN and Form W-7 guide. Opinion: assemble the folder before rate-shopping, because a complete file turns a 60-day foreign-national closing into a calendar item instead of a cliffhanger.
A US mortgage is a different animal than a Canadian one
The structural differences matter more than the rate sticker. A US loan fixes its rate for the full 30 years and amortizes over the same 30; a Canadian mortgage fixes a 5-year term over a 25-year amortization and renews at market every term. The US borrower buys certainty and pays for it in rate; the Canadian borrower rolls renewal risk every five years. US loans allow free prepayment in the mainstream market, while Canadian fixed terms carry interest-rate-differential penalties. US closings escrow property taxes and insurance into the monthly payment by default; Canadian loans mostly leave them to the borrower. And the US quote arrives on federally standardized TRID paper (a Loan Estimate within three business days of application, a Closing Disclosure three business days before signing), which makes lender-to-lender comparison mechanical rather than rhetorical.
| Dimension | Federal CA | Federal US | State (FL) |
|---|---|---|---|
| Qualifying test | OSFI B-20 stress test: contract rate + 2 pts or floor (federally regulated lenders) | DTI on actual contract rate; program caps, no stress add-on | n/a |
| Standard structure | 5-year term, 25-year amortization, renewal risk | 30-year fixed or ARM, no renewal | n/a |
| Quote disclosure | Lender-specific formats | TRID: Loan Estimate and Closing Disclosure (CFPB, 12 CFR 1026) | n/a |
| Taxes on the loan itself | None | None federal | Doc stamp on the note: 0.35 USD per 100 USD (Fla. Stat. 201.08); intangible tax: 2 mills on the mortgage (Fla. Stat. 199.133) |
| Default insurance | CMHC regime for high-ratio resident loans | PMI for resident low-down loans; not offered on foreign-national programs, hence the 25 to 35 percent down | n/a |
Worked example: the calculator's default scenario, written out
Take the tool's defaults as of June 2026 and label them honestly: a 500,000 USD purchase, 30 percent down (150,000 USD), a 350,000 USD loan, and the tool's placeholder rates of 7.25 percent on the 30-year fixed, values you replace with your own quotes. At 7.25 percent over 360 payments, principal and interest run about 2,388 USD per month; at the tool's default 1.38 CAD per USD, roughly 3,295 CAD before property tax, insurance and HOA. Lifetime interest on the fixed structure at that rate is on the order of 510,000 USD, which is the price of never facing a renewal. Florida's two loan taxes land at closing: 1,225 USD of documentary stamps on the 350,000 USD note and 700 USD of intangible tax, items the doc stamp and intangible tax guide breaks down and the doc stamps calculator computes for any amount. Model your full cash-to-close, taxes and all, with the total purchase cost calculator. Opinion: on these inputs the 7/1 ARM at the tool's 6.75 percent default saves about 116 USD per month for seven years; it is the right trade only if your realistic horizon for selling or refinancing is shorter than the fixed period, a judgment the ARM section above frames.
Where this tool fits in the buying sequence
The calculator earns its keep twice in a purchase. Before the offer, it converts a listing price into a monthly CAD reality and tells you whether the financing contingency you are about to sign is realistic for your channel: a foreign-national underwrite that needs 45 to 60 days should never sit inside a 30-day loan approval window. After the Loan Estimate arrives, the tool becomes a verification instrument: enter the quoted rate and your actual down payment and the payment line should reconcile with page one of the Estimate to the dollar, before taxes and insurance. The wider sequence (offer, contingencies, escrow, closing) is mapped step by step in the manual's 12-step buying diagram, and the contract mechanics that protect your deposit while financing is pending are in the earnest money deposit guide. Opinion: run the stress pass (rate plus two points) the same evening you get a quote; it is the single cheapest piece of underwriting discipline a Canadian buyer can self-administer.
Common mistakes
Rate-shopping before assembling the file, then watching a 45-day contract clock beat a 60-day underwrite. Comparing a US 30-year fixed to a Canadian 5-year rate as if they were the same product; they price different risks. Ignoring the two Florida loan taxes and discovering nearly 2,000 USD of closing-day charges on a 350,000 USD note. Assuming a US credit score is required: channel one reads your Canadian bureau, and DSCR reads the rent roll. Letting the bank's posted FX rate price your down payment instead of a planned conversion route. Forgetting reserves, the quiet test that fails otherwise-qualified files. Quoting one lender only, when TRID paperwork makes three quotes trivially comparable.
Actionable checklist
- Pick your channel: cross-border bank, foreign-national lender, or DSCR for a rental.
- Assemble the document folder before the first application.
- Run this calculator with your real quotes; re-run at rate plus two points as a personal stress test.
- Collect three Loan Estimates and compare line by line.
- Budget the Florida note taxes (0.35 percent doc stamp plus 2 mills intangible) into cash-to-close.
- Plan the down-payment conversion with a real FX route, not the wire-day posted rate.
- Confirm reserve requirements in writing and where the funds may sit.
- Calendar the closing against your contract's financing contingency dates.
FAQ
Can a Canadian get a US mortgage without a US credit score? Yes. Canadian-bank US subsidiaries underwrite on your Canadian bureau, and DSCR programs underwrite the property's rent. Pure US foreign-national lenders price the absence of a score into the rate and down payment.
What down payment should I plan for? Around 20 to 25 percent through a cross-border bank program, 30 to 35 percent at a foreign-national lender, and program-specific floors on DSCR. Below those numbers there is no PMI-style rescue for non-residents.
Why is my quoted US rate higher than my neighbour's conforming rate? The foreign-national premium, typically 0.5 to 1.5 points, prices the missing US file. Moving your banking and credit history south over a season or two usually migrates you to better pricing.
Is there a stress test like Canada's B-20? No. US lenders qualify you at the contract rate under their DTI caps. The discipline is yours: re-run this calculator at a higher rate before you commit.
What taxes does Florida charge on the mortgage itself? Documentary stamps at 0.35 USD per 100 USD of note and intangible tax at 2 mills of the secured amount, both due at recording.
Do ARM products make sense for a snowbird buyer? A 7/1 ARM prices below the 30-year fixed and fits a genuine sub-seven-year horizon; it reintroduces the renewal-style risk Canadians know. Match the structure to your exit plan, not to the teaser gap.
Does the calculator give me a quote? No. It models payments and CAD conversion on the numbers you enter. Quotes come from lenders on a Loan Estimate, which is the document to compare.
