When the Seller Is the Bank: Seller Financing in Mexico

If you are weighing seller financing for Mexico property — a payment plan offered by the person selling the land rather than by a bank — the first thing to know is that it barely resembles a mortgage. No loan officer, no credit check, no standard form. A seller owns the lot, a buyer cannot or will not pay the full price today, and a contract holds them together until the balance is paid.

Bank mortgages on raw land are rare on this coast and rarely reach foreign buyers; most sales close in cash. So when a payment plan appears, it is a private arrangement between you and the seller. The structures are few, the terms follow patterns, and the paperwork that protects a buyer is well understood by every honest notario on the coast — as is the paperwork that protects no one. For the wider process, start with our complete guide to buying land in Oaxaca.

Key facts

Bank mortgages for raw lots are rare — especially for foreign buyers, so seller financing here means a private arrangement, not a bank product.
Three structures exist — the promesa with title at the end, the immediate deed with a hipoteca, and the informal apartado; knowing which you are in is the whole game.
Title held until paid is the common one — the seller keeps the escritura in their name until the final payment; your protection is the registered contract.
The notario must be involved — have one draft or review the contract before you sign.
Receipts and registry filings protect you — register the contract or hipoteca and keep a dated receipt for every payment.
Default clauses deserve a lawyer's read — the cost of missing a payment is written before you sign.

None of this is exotic. Sellers here have long carried balances for buyers they trust, and the notario and registry have always had ways to make it safe. What varies is how carefully the deal is built.

The seller as bank

When the person selling is also the lender.

Why would a seller act as a bank? A payment plan widens the pool of buyers to anyone who can pay a large share now and the rest later — and where cash buyers are a short list, that can mean selling this year instead of next. Sellers who carry a balance also hold closer to asking price, because they are being paid for waiting.

Buyers choose it because the alternative is usually not a bank loan — it is waiting. Mexican banks rarely lend on vacant land: an empty lot produces no income, so it is weak collateral, and foreign buyers seldom have the credit history a Mexican mortgage would require. A payment plan lets you buy now, lock today's price, and keep part of your cash for the build. On a raw lot in a small town, seller financing almost always means one of three structures.

Promesa, hipoteca, apartado

Three ways a payment plan is built.

Each structure answers three questions: who holds the title, what the public registry shows, and what happens if the payments stop.

Structure	Who holds title	What the registry shows	Risk for buyer	When you see it
Promesa de compraventa — payments now, deed at the end	The seller, until the final payment	Seller as owner; your promise recorded if you register it	Medium — strong if registered, weak if not	Most raw-lot payment plans on the coast
Immediate deed with a hipoteca — title now, lien for the balance	You, from signing	You as owner; the seller's hipoteca recorded as a lien	Lower on ownership; default can still cost the lot	More common in towns and formal developments
Apartado strung into a "plan" — receipts only	The seller, always	Seller as owner; nothing recorded	High — you own receipts, not land	Informal sales — avoid or convert

The first structure dominates. A promesa de compraventa is a purchase promise: both sides commit to a sale at a fixed price, you pay in installments, and when the balance is complete you go to the notario, where the escritura — the public deed — is signed into your name. Until that day the seller remains the owner of record; your protection is the contract, and the note it leaves in the public registry if you register it.

The second structure is closer to a classic mortgage. The seller transfers the deed now and registers a hipoteca for the unpaid balance: you own the lot from day one, and the seller holds a secured claim against it. It is less common here, because foreign buyers inside the restricted zone acquire through a bank trust — the fideicomiso — and few sellers build financing on top of that trust paperwork.

The third needs care. An apartado is a reservation receipt that holds a lot briefly while you arrange the real purchase — the difference is covered in our guide to option agreements and reserving lots. It is not a financing plan. When a seller takes installments for years and gives you nothing but apartado-style receipts, you are not buying land on time; you are lending the seller money against a promise.

The price of time

What sellers actually ask.

Terms vary wildly — every seller sets their own. These are patterns we see on the coast, not a price list, and any seller's numbers deserve the same scrutiny you would give a bank's.

Down payment. When a seller carries the balance for a year or more, expect to put down a substantial share — commonly 30–50% of the price, sometimes more. A smaller deposit, often 5–10%, may bind a short promise that closes within months, but that is not a multi-year plan.
Length. Terms are usually short — one to three years is the common range — with payments monthly, quarterly, or in agreed lumps. Longer plans exist on larger prices, and the longer the term, the more the seller wants in return.
Interest. Some sellers charge none, because the full price already includes the wait. When interest is charged, it is often in the high single digits or more: this is an unregulated lender taking real risk, not a bank competing on rates. Sometimes the cost hides in a firmer price; know which one you are agreeing to.
Default. The clause that decides everything. Expect a grace period and late fees; the harder question is what the seller may keep. Some contracts retain payments made as compensation; the harshest say you lose everything paid and the lot returns to the market. Courts do not always enforce the harshest version, but you do not want to be the test case — have a lawyer read it before you sign.

Where the deal breaks

Where buyers get hurt.

Seller financing concentrates risk in a handful of places. Knowing them is most of the defense.

Default is the big one. Miss enough payments and the contract collapses; depending on the clause you signed, you can lose payments already made, sometimes all of them.
The seller sells again. An unregistered promise does not stop a seller from selling the lot twice, and where two buyers claim the same land, the one who registered first is stronger. Our guide to registering your deed shows how the filing works.
The seller's own troubles. While the title stays with the seller, their debts can reach the lot, and if the seller dies mid-plan, heirs inherit the obligation to transfer it. A registered contract binds the property; a handshake binds no one.
Your own troubles. If you die before the balance is paid, your heirs inherit the right to finish the purchase — if they can find the contract. Cross-border succession is slow, and undocumented deals tend to become abandoned payments.
Vague receipts. A stack of receipts that do not name the lot, the price, or the schedule is not evidence of a purchase; it is evidence that money changed hands.
Weak title underneath. A payment plan does not fix a title problem; it makes it more expensive. If the land is an acta de posesión or communal, financing adds years of exposure to a title that was already informal.

The risks run both ways. A seller who carries a balance has capital tied up in a promise, keeps the lot in their name, and may watch you stop paying, leaving them to restart a sale after months off the market.

Proof, in writing

The paperwork that protects you.

The structures above are only as strong as the paper under them. Six pieces of paper do most of the protecting.

The notario, from day one. A notario público is a state-appointed lawyer who authorizes property transfers. Have yours draft or review the contract before you sign — our guide to the notario explains what they check. The same notario prepares the escritura and files the deed at the end.
A registered contract or hipoteca. Filing the promesa — or the hipoteca — in the Registro Público de la Propiedad makes your interest visible to anyone who searches the lot. That filing is the difference between a private dispute and a right that binds the property and any later buyer.
The pagaré. Sellers often ask you to sign pagarés — promissory notes — for each installment, giving them a fast enforcement route if you default. They must mirror the schedule exactly, be returned as each is paid, and never be signed blank.
A receipt for every payment. Dated, signed, naming the lot and the contract. Pay by bank transfer where you can, so the trail survives even if paper is lost.
An early-payoff clause. Ask for the right to pay the balance ahead of schedule without penalty. Some sellers even discount for early payment.
The closing clause. The contract should state who chooses the notario, who pays the closing costs — commonly 5–8% of the price — and how long the seller has to deliver the deed once the final payment clears.

A fair trade, done fairly

The honest verdict.

Seller financing can be an excellent tool for the right lot and the right seller. It works when you have most of the price but want to keep cash for building; when the title is clean; when the contract is drafted or reviewed by a notario, registered, and backed by receipts; and when the seller is someone you can verify. In those conditions, a payment plan is simply a slower closing.

It is not a discount hack. A seller who finances you is giving up the cash alternative and prices that in — through a firmer price, interest, or both. If terms undercut every cash price on the coast, ask what you are actually signing; the discount may be living in the default clause.

And one rule covers the rest: if a deal feels designed to avoid the notario — if the registry never comes up, if the receipts are handwritten, if the paperwork is "not necessary between friends" — treat that as the answer.

When a deal is built to avoid the notario, you are not buying land. You are buying a promise — and so far, only the seller has been paid.

Our role

How we handle payment plans.

Every lot we list carries its real price and its title type, stated plainly — and the same goes for terms. When a seller on this coast offers a payment plan, the listing says so, with the down payment, schedule, and structure named up front. When a seller has no plan, we do not invent one; financing is a feature of a deal, not a trick to make one affordable.

We keep our role narrow on purpose: we introduce buyers to licensed Mexican brokers and notarios, and we never hold buyer money or collect installments — deposits and payments go directly to the seller or their broker under a written agreement, and every closing runs through a notario. That separation is what lets us tell you plainly whether a payment plan is built well or built to fail.
