Six routes for foreign buyers in Mexico: cash, US or Canadian HELOC, USD non-resident mortgage from a Mexican specialty lender, Mexican peso mortgage, seller financing, self-directed IRA. Cash and HELOC usually win; peso mortgages rarely do for non-residents.
The route fits the buyer. Cash works if you have the savings and don't need the capital invested elsewhere. HELOC works if you have meaningful US or Canadian home equity. USD non-resident mortgages from Intercam, Hipotecaria Casa Mexicana, or Banco Sabadell México work if you want leverage and have no HELOC capacity. Mexican peso mortgages mostly work for Mexican tax residents. Seller financing is opportunistic. A self-directed IRA is for pure-investment US buyers only.
Route 1: Cash purchase
Cash is what most foreign buyers actually do. The Mexican mortgage market for non-residents is small, the rates are higher than US conventional, and the documentation drag is real, so for buyers with the savings to do it, cash usually wins on simplicity.
What it looks like in practice:
- A single wire from your foreign account to the notario público's escrow
- No lender appraisal, no underwriting clock, no second institution to coordinate with the notario
- Closing in roughly 60-90 days instead of 90-150 days
- No monthly payment, no peso/USD exposure on payments, no mortgage lien on the title
The cost is the leverage you give up: that capital is not earning a return elsewhere. For buyers without substantial non-registered savings, or for buyers who want their cash deployed in US or Canadian markets, financing is the right move.
If you're funding cash from the sale of a US investment portfolio, the capital-gains hit on the portfolio sale is a real number. Model the all-in cost including that tax exposure before you commit.[IRS, capital gains framework on investment sales, 2026-04]
Route 2: Mexican peso mortgage
Mexican banks (BBVA México, Santander, Banorte, HSBC México, Scotiabank) offer mortgages to foreign buyers, but the terms are tough on a non-resident:
- Loan denominated in pesos
- LTV typically 50-65% for non-resident foreign buyers; higher for Mexican tax residents
- Rates roughly 10-13% for non-resident applications, varying by bank, applicant profile, and where Banxico's overnight rate is sitting[Banco de México, Reporte de Estabilidad Financiera (semi-annual housing credit and mortgage market data), 2026-04]
- Documentation: foreign passport, 12+ months of bank statements, a foreign credit report, and an RFC (Registro Federal de Contribuyentes, the Mexican tax ID)
The case against, for a non-resident:
- Payments are in pesos. If your income is in USD or CAD, you eat the FX spread on every payment, and a 10-15% peso move against your home currency rolls straight into your monthly nut
- Rates run several points above US conventional
- Underwriting for foreign buyers often takes 90+ days
- LTV ceilings are lower than what you can get from a USD specialty lender
If you've already established Mexican tax residency and can document Mexican-source income, the math can flip. For a non-resident with USD or CAD income, this route rarely wins.
Route 3: USD non-resident mortgage from a Mexican specialty lender
A handful of Mexican lenders originate USD-denominated mortgages to foreign buyers. Intercam Banco, Hipotecaria Casa Mexicana, and Banco Sabadell México are the most commonly cited names; MoXi (Global Mortgage) brokers across the set.[Global Mortgage (MoXi), Mexico Mortgage Rates for U.S. Buyers — published USD rate and LTV ranges for non-resident foreign buyers, 2026-04]
What you typically see:
- USD-denominated loan, USD payments, no peso exposure on debt service
- LTV 60-70% depending on lender, property type, and borrower profile
- Rates roughly 8-10%, well below Mexican peso rates and a few points above US conventional. Closer to 8% on a strong file, closer to 10% on tougher ones
- 15-25 year amortizations
- For coastal restricted-zone property, the lien is recorded against the fideicomiso interest, so your lender needs to know how to work with a bank-trustee fideicomiso
This route is a smaller market than US conventional. The lender pool is concentrated, and not every US loan officer can originate one. Expect to work with a cross-border specialist or a broker who covers these lenders.
Route 4: HELOC against your US or Canadian home
A home equity line of credit on your existing primary residence is often the single best financing route for cross-border buyers. The rate is the cheapest in the stack, the underwriting is in your home country, and the Mexican closing looks like a cash deal from the notario's perspective.
- US HELOC: rates track US prime plus a margin, typically running 7-9% for borrowers with strong credit; combined LTV with the first mortgage usually capped at 80-85%[Bankrate, current HELOC rate tracker (national average and prime-plus-margin framework), 2026-04]
- Canadian HELOC: similar mechanics, usually tracking Canadian prime plus a margin
- Funds wire to the notario's escrow as cash; the Mexican title closes clean with no mortgage lien
- Interest deductibility: under US tax law, interest on a HELOC used to buy a foreign personal-use property is not deductible against ordinary income; if you trace the proceeds to a rental, interest may be deductible against rental income, subject to the tracing rules in Pub 936[IRS Publication 936, Home Mortgage Interest Deduction, 2026-04]
The cost: you're using up US or Canadian home-equity capacity that could fund something else later, and you're carrying a variable rate that moves with prime.
Route 5: Seller financing
On a meaningful share of private-party sales, especially in expat-heavy markets like San Miguel de Allende, Lake Chapala, and parts of the Riviera Maya, sellers will carry paper. Typical terms run 30-50% down, 6-9% interest, 5-10 year amortization or balloon, and the note can be denominated in either pesos or USD depending on the seller's preference.
Two cautions: the lien needs to be properly recorded with the notario (not a private side agreement), and you want a Mexican real estate attorney reviewing the contrato de compraventa con reserva de dominio or whatever instrument the seller proposes. A handshake deal in another country is just an unsecured loan with extra steps.
Route 6: Self-directed IRA (US buyers, investment use only)
If you're a US buyer and the property is a true investment (no personal use, ever), a self-directed IRA can hold Mexican real estate. The IRA owns the property through an LLC, all income and expenses run through the IRA, and you can never stay in the home yourself without triggering a prohibited transaction.
This is a narrow tool. It works for pure rental investors who want to deploy retirement capital tax-deferred. It does not work for anyone who wants a place to use, even one weekend a year. Consult a CPA familiar with self-directed IRAs and IRC Section 4975 before going down this path.
How to choose between the routes
A few questions usually settle it.
Do you actually need leverage? If non-registered savings cover the purchase comfortably and you don't need that capital working elsewhere, cash wins on simplicity. If leverage is required to make the purchase feasible or to preserve capital you need invested, financing is in.
Do you have meaningful home equity in the US or Canada? If yes, a HELOC is almost always the lowest-friction route. Cheaper than anything originated in Mexico, and the closing in Mexico runs as a cash deal.
Is the property in the restricted zone? Coastal property within 50 km of any coast or 100 km of a land border requires a fideicomiso, which complicates the lien structure for any Mexican-side mortgage. Some lenders work with this fluently; others don't.[Mexican Constitution, Article 27 (foreign-ownership restricted zone: 50 km coastal, 100 km border), 2026-04]
Are you a Mexican tax resident, or planning to become one? Tax residency unlocks better terms on a Mexican peso mortgage. Without it, a non-resident faces the worst pricing in the market.
How is your income denominated? If you're paid in USD or CAD and your monthly mortgage is in pesos, a 10-15% peso move against your home currency hits your monthly payment directly. USD-payment products (HELOC, USD non-resident mortgage) keep this out of your life.
For most foreign buyers, the order of preference looks like this: cash if you have it, US or Canadian HELOC if you have the home equity, USD non-resident mortgage from a Mexican specialty lender if you need leverage and don't have HELOC capacity, seller financing if it's offered and the terms are real, Mexican peso mortgage only if the others are unavailable. Self-directed IRA is a separate track for pure-investment US buyers.

What a financed purchase actually costs
The all-in number includes:
- Purchase price
- Mexican closing costs of roughly 5-9% of purchase price (notario fees, transfer tax, registry, fideicomiso setup if coastal). See /mexico/closing-costs/ for the breakdown
- Financing-side closing costs of roughly 2-4% of the loan amount (lender origination, appraisal, mortgage recording at the Registro Público, optional title insurance)
- Ongoing principal and interest, plus servicing
- Fideicomiso annual fee if coastal ($500 USD–$750 USD)
- Annual predial (property tax) and other carrying costs
For a $400,000 USD coastal property with a $250,000 USD USD non-resident mortgage at 8% over 20 years:
- Cash at closing: $150,000 USD down + $28,000 USD closing (7%) + $7,500 USD financing-side (3% of loan) ≈ $185,500 USD
- Monthly P&I: ~$2,090 USD
- Annual carrying cost (mortgage + fideicomiso + predial + insurance): ~$28,000 USD–$32,000 USD
Run these against expected rental income if it's an STR, or against the use-value you actually get out of it if it's personal use.
Where buyers commonly stumble
A few recurring failure modes worth flagging.
Defaulting to a Mexican peso mortgage because the local agent suggested it. The agent is recommending what they know, not what's optimal. For a non-resident with US or Canadian income, a HELOC or USD non-resident mortgage almost always wins on rate and FX exposure. Compare before you commit.
Underestimating the financing-side closing costs. The 2-4% on the loan amount sits on top of the 5-9% Mexican-side closing costs. On a $250,000 USD loan at 3%, that's $7,500 USD in fees most buyers haven't budgeted for.
Misjudging how a lender handles fideicomiso. For coastal property, the lien gets recorded against the fideicomiso interest, and not every lender knows how to do that cleanly. Ask the loan officer to walk you through fideicomiso lien recording before you submit an application; if they can't, find another lender.
Ignoring FX risk on a peso-denominated loan. The peso has moved 15-20% against the USD inside a single year more than once over the last decade. If your income is in USD and your mortgage is in pesos, your effective monthly payment can swing meaningfully without notice. The /newsletter tracks the rate moves and FX prints worth watching.
