The order a Vietnamese purchase actually happens in, start to certificate.

Three conditions, all of them ahead of price. The project has to be an approved commercial housing project that appears on the relevant province’s eligible list. It cannot sit in a national-defence or security-restricted zone. And the building has to have room left under the 30% foreign-ownership cap. Those conditions come from the Housing Law 2023 and the Land Law 2024, both effective 1 August 2024.

Two things a foreigner cannot buy follow from the same frame: a standalone land plot, because land-use rights are not available to foreigners, and a house from a private seller outside a commercial project. The category is fenced before you start looking, which is why the first question on a Vietnamese listing is not what it costs. It is whether a foreigner is permitted to own this specific unit at all. The cap, the ceiling and the eligibility gate, in full.

Nothing here is a criticism of the Vietnamese system. The rules are published and knowable, and every loss in this market belongs to a buyer who did not read them before wiring. The tourist starts at the balcony. The operator starts at the fence.

By asking the developer for the building’s current foreign-ownership count against the cap, in writing, on letterhead, dated to the purchase. The Housing Law 2023 sets the ceiling at no more than 30% of the apartments in any single building, and no more than 250 landed houses inside a ward-equivalent area.

The detail that decides the outcome is when the count is tested. The quota is checked at registration, not at deposit. A building that had headroom in March and none by the time your dossier reaches the registry will not issue a certificate in your name, and the money you have already paid does not change that arithmetic. A verbal “there is room” from a sales desk is a sentence; a dated letter is a document. The pre-wire checklist runs this as a binary gate.

On off-plan stock the Law on Real Estate Business 2023 caps the deposit a developer may take at 5% of the sale price, and that deposit counts inside the first installment, which may not exceed 30% of contract value. The deposit may only be collected once the project meets the conditions for the sale of future housing.

What the agreement commits you to is whatever it says about the refund, and that is the clause to negotiate before anything moves. Write the eligibility and quota position into it as a condition of the deal, so a gate that fails returns your money instead of starting a conversation. A deposit agreement that survives a failed quota check is a deposit agreement written for the seller.

Under the Housing Law 2023 a housing sale contract takes effect from the date it is notarised or authenticated. The same law carves out cases where one party to the transaction is an organisation, which is the shape of a purchase made directly from a developer.

In practice that splits the market in two. A resale between two individuals goes through a notary office, and the notarised contract is what the registry and, later, the bank will want to see. A first-hand purchase from a developer usually does not, and the contract itself fixes the payment schedule and the handover terms. Confirm which of the two you are in with your own Vietnamese lawyer before you sign, because the document that makes the deal effective is not the same one in both cases.

Whichever side you are on, the contract is still a claim, not the asset. A contract is a promise; the certificate is the thing you own.

Through the licensed banking system, as foreign currency converted inside Vietnam. Cash is not the channel, and buying dong overseas and sending dong in destroys the origin story before you have closed.

Vietnam issues no single foreign-exchange certificate equivalent to the Thai FET form. What it runs instead is capital controls, and that makes the inbound record load-bearing rather than administrative. Wire foreign currency to a Vietnamese bank, convert it there, and keep every inward-remittance confirmation and every foreign-exchange conversion slip. On a staged off-plan purchase the discipline has to hold across every tranche, not just the first: one payment made outside the channel is the gap that surfaces years later. The money-in trail, and why it decides whether money can come out.

Statute puts it at not more than 10 working days after a complete dossier reaches the registry. The word carrying the weight is complete.

The certificate issues only after the developer has discharged its own land-use and financial obligations for the project. On completed stock from a developer that has cleared those obligations, issuance is a documentary process and the statutory window is a reasonable expectation. On off-plan stock where the obligations are unresolved, no buyer’s dossier in the building is complete, no certificates issue, and the wait runs from months into years while you occupy a unit you cannot yet registrably own.

So the question to put to a developer is not whether the building will be finished. Plenty are finished. The question is what stands between the current state of the project and issuance, and whether this developer has actually delivered certificates to foreign buyers on its earlier completed phases. What the pink book grants, and the timing gap behind it.

Foreign ownership of the dwelling runs up to 50 years from the issuance of the certificate, extendable one time by up to a further 50 years on an application filed before expiry. A foreigner married to a Vietnamese citizen may hold long-term, like a citizen.

Two consequences follow for the underwriting. The clock starts at issuance, not at contract, so a long off-plan wait does not eat the term but does delay the point at which you hold anything registrable. And a later foreign buyer inherits the years that remain rather than a fresh term, so the asset you sell is shorter than the one you bought. Treat the extension as upside rather than as the plan, and model the slice you can actually sell. The wasting-asset math on the 50-year term.

You get the keys. You do not yet get the title. Under the Law on Real Estate Business 2023 the total paid before handover may not exceed 70% of contract value, and the final 5% may be withheld until the ownership certificate issues in your name. That retention is the only real leverage a buyer holds over the last step, so do not sign it away.

Handover is also when money changes hands in ways the brochure price does not always show. The one-time 2% maintenance fund falls due at handover; the 0.5% registration fee is triggered when the certificate registers; and on a new unit from a developer 10% VAT is usually already inside the quoted price, which is worth confirming in writing rather than assuming. Every tax a foreign owner meets, buy to sell.

Once the unit is let, the tax that matters is charged on the top line: a flat 10% of gross rent, 5% VAT and 5% personal income tax, above an annual rental threshold of ₫100 million. There are no deductions against it, so it is a haircut on revenue rather than on profit.

Four things, in roughly the order they bite. The building was already at the 30% cap when the dossier arrived, so the certificate cannot issue whatever you paid. The developer’s land-use and financial obligations are unresolved, so no dossier in the building is complete and nobody gets a certificate. A payment moved outside the banking channel, which breaks the inbound record the repatriation right rests on. Or the project stalls before completion and a contractual claim against a developer entity is all you are holding.

None of those four requires anyone to behave badly. Three are the published structure doing exactly what it says, and the fourth is the generic off-plan pattern that exists in every off-plan market on earth. The off-plan risk, stated plainly.

The defence is sequencing, not optimism. Clear the fence, get the quota count in writing, cap what you pay before handover, keep the bank file complete from the first tranche, and hold the last 5% until the certificate carries your name. The exit is priced at entry: the term, the quota and the paperwork you kept all decide who can buy the unit off you later. What the exit looks like from the other end.
