Due Diligence on the Developer, Project & Agent: The Buyer-Protection Checklist Before You Wire a Dong

Step 1 - Confirm this specific project is legally cleared for foreign sale

Foreign eligibility is project-specific and capped. Under the Housing Law 2023 and Decree 95/2024/ND-CP (effective 1 August 2024), foreigners may own up to 30% of the apartments in a single building (per block where blocks share a base), and up to 250 landed houses within one ward-equivalent area. A project in a national-defence or security zone is entirely off-limits to foreigners. Verify these four things on paper before you fall in love with a unit:

1. The provincial Department of Construction (So Xay dung) 'eligible to be put into business' notice for THIS project and THIS phase - this is the master gate; no notice means the developer cannot legally take a deposit.
2. Confirmation in writing that the building still has foreign quota left under the 30% / 250-house cap - ask the developer for the current foreign-ownership count, not a verbal 'plenty available'.
3. The Investment Registration Certificate (IRC) / in-principle investment approval and the Land Use Right Certificate (So do / So hong) for the land parcel, in the developer's name.
4. The 1/500 master-plan approval and the construction permit - and, for off-plan apartments, the certificate that the building foundation is complete. Cross-check the project name and parcel number against the Ministry of Construction / provincial portal listings, not just the brochure.

Step 2 - Verify the off-plan safeguards: bank guarantee and the 5% deposit cap

The Real Estate Business Law 2023 added hard buyer protections for off-plan (forming-in-future) property - use them as a checklist. The developer must have been approved for a bank guarantee (bao lanh) from a licensed Vietnamese commercial bank covering its financial obligation to refund you if it fails to hand over. Ask to see the guarantee commitment letter naming the project, and note you are entitled to choose whether a per-buyer guarantee is issued. The off-plan deposit is capped at 5% of the sale price, and the deposit agreement must state the price and the unit area. The first installment (deposit included) must not exceed 30% of contract value, and total pre-handover payments to a foreign-invested developer are capped (commonly 50% before you receive the unit). If a salesperson pushes you to pay 30-50% 'to lock the price' before any DoC notice exists, walk away.

Step 3 - Confirm the agent or 'developer rep' actually has authority to sell

This is where most ZH/TW buyers get burned: a 'zhong jie' you met only on WeChat or Zalo takes a deposit to a personal account and disappears. Authority must be documented. Before paying anyone:

1. Ask for the developer's written Sales & Purchase Authorization, OR the brokerage's distribution/agency contract with the developer naming this project - read the dates and the project name, do not accept a screenshot.
2. Confirm the brokerage is a registered company (check the enterprise registration / tax code) and that, under the 2023 law, it trades through a licensed real-estate trading floor or registered brokerage - individual free-agent brokering is being phased out.
3. Insist that the deposit and all payments go to the DEVELOPER'S named corporate bank account shown on the official price list and SPA - never a personal account, never a third-party 'collection' account, never crypto or cash to a courier.
4. Get the SPA (sale & purchase contract) issued by the developer in the buyer's name; a real transaction is notarized and registered, not settled on a chat app. If the 'agent' resists notarization or video-verification of the developer's office, treat it as fraud.

Step 4 - Vet the developer's track record and financial strength (the stalled-tower test)

After the 2023-2024 credit crunch, a large stock of projects across Vietnam stalled, with substantial capital trapped - exact counts are disputed and in flux, so treat any single figure as indicative and confirm current status with your advisor. The practical lesson: a beautiful brochure does not mean a delivered building. Pressure-test the developer:

1. Delivery history - how many projects has this developer actually handed over, on time, with pink books issued to foreign buyers? Ask for a named, visitable completed project.
2. Land status - is the project land mortgaged to a bank? Mortgaged collateral land can block your title. Ask whether the specific units have been released from any bank mortgage (giai chap) before sale.
3. Construction reality - visit the site or get dated progress photos/independent verification; match progress against the payment schedule so you are never paying far ahead of build.
4. Corporate health - check the developer entity's enterprise registration, any litigation or bond-default news, and whether group affiliates have stalled projects. A reputable co-developer or a foreign joint-venture partner is a positive signal, not a guarantee.

Step 5 - Red flags that signal a scam (stop and verify)

Any one of these should halt the transaction until independently cleared:

1. No physical office you can visit, or refusal to do a live video walk-through of the developer's sales gallery.
2. The seller works only through a personal social account (WeChat/Zalo/Facebook), uses a personal or mismatched bank account, or asks for crypto/cash.
3. Refusal or 'delay' in showing the DoC eligibility notice, the bank guarantee, the IRC, or the land title - or only ever sending cropped screenshots.
4. Pressure tactics: 'last unit', 'price rises tomorrow', or demands for a 20-50% deposit before any legal file is shown.
5. A price suspiciously below market, a 'guaranteed rental return' or 'guaranteed buyback' in writing (often unenforceable hype), or a contract only in a language you cannot read with no bilingual notarized version.
6. The unit is sold as foreigner-eligible but the project is in a restricted zone or the building's 30% foreign quota is already full.

Step 6 - Protect the money trail and your future exit

How you pay determines whether you can prove ownership and later take your money out. Route the purchase funds into Vietnam through official banking channels and keep every record - the inbound transfer evidence, the notarized SPA, tax receipts, and the pink book. When you eventually sell, Vietnamese rules require you to repatriate proceeds through a licensed bank using a designated account, and you must show that the original purchase funds came from abroad. Buyers who paid cash to a personal account, or who never documented the inbound transfer, struggle to remit proceeds out later. Bank-channel discipline at the deposit stage is also your fraud firewall: a legitimate developer is always paid into a verifiable corporate account. FX, remittance and tax rules change - confirm the current State Bank and tax circular details with your bank, advisor or lawyer before transferring.

A 10-minute pre-wire checklist

Run this before any money moves. If you cannot tick every box with a document in hand, do not pay:

1. DoC 'eligible to be put into business' notice for this project/phase - seen and matches the project name.
2. Foreign quota confirmed available (30% per building / 250 houses per area not exhausted) and project not in a restricted zone.
3. IRC + land title (So hong) in the developer's name; land not blocking title via unreleased mortgage.
4. Bank guarantee (bao lanh) commitment letter from a licensed Vietnamese bank, naming the project.
5. Seller's written authority (developer authorization or registered distribution contract) verified, and brokerage's tax code checked.
6. Deposit <= 5% of price, first installment <= 30%, paid ONLY to the developer's named corporate account, against a notarized agreement.
7. Inbound funds documented through official banking channels for your future exit.
