The lease already contains the answer: a notice period, a deposit to offset arrears, and exit terms. What matters is hearing about the missed month immediately. That comes from your statement, not from a silence you notice later.
A missed payment is a bad month. Finding out about it in month three is a bad year, and that difference is operational, not legal.
The statement flags it before it grows
Rent that did not arrive shows in the monthly statement for that month, marked as what it is. Judge any reporting system by exactly this case: when the news is bad, the statement should say so on schedule. Reporting that goes quiet when something is wrong reads as fine from Hong Kong, and that is how one missed month becomes three.
That visibility rule is the same one we apply to ourselves at property management: rent received, itemized expenses, and anything waiting on your decision, every month, whether the month was good or not.
The sequence that follows a missed month
What happens next runs on the lease, in order:
- The reminder. Late payments come in two shapes. One is the tenant who simply forgot: a transfer delay, a travel week, fixed with a message. The other is the tenant who has already decided to leave and is stretching the last week or two while the lease still says the tenancy is running. That second one is not a payment problem at all. It is a notice problem wearing a late transfer as a disguise, and it is why the first reminder should ask what they intend to do at renewal, not only when the money is coming.
- The formal notice. If reminding fails, the lease’s notice mechanics start, in writing. Find that clause before you need it — the notice period and the definition of default usually sit in the same paragraph, and those two lines decide how fast you are allowed to move.
- The deposit offsets. Arrears net against the deposit, with amounts documented against the record, the same deposit record a clean handover file establishes. One to two months’ rent is the normal deposit in Hanoi, per expat.com’s Hanoi housing guide updated April 2025, and no statutory figure is set for you. Do that arithmetic once: a deposit at that level absorbs one missed month and does not absorb three. This is where the paperwork discipline earns its keep, because an offset against a written record closes in a message and an offset against memory opens an argument.
- The exit terms. If the tenancy has to end, it ends on the grounds the lease sets out, inside what the law allows. Article 172 of the Law on Housing 2023 (No. 27/2023/QH15, in force 1 August 2024) lets a landlord terminate unilaterally once rent has gone unpaid for three months or more without a justifiable reason, and requires at least 30 days’ written notice from whichever side ends it.
Put those two numbers next to the deposit and the case for acting early makes itself. A one-to-two month deposit is exhausted well before month three, and the statutory notice adds another month on top. By the time you are clearly entitled to end the tenancy, the deposit has already stopped covering anything. That is the whole argument for treating month one as the decision point.
None of the steps needs you in Vietnam. All of them need someone in Hanoi who answers, documents and follows through, and a lease that was written with these clauses in the first place. What stays with you is the decision at each gate: whether to remind again, when the formal notice goes, and whether the tenancy is worth saving. The manager brings you the file; the call is yours.
When is it cheaper to end the tenancy?
Churn arithmetic cuts both ways. One vacant month plus a re-letting fee costs roughly 17% of a year’s rent (one month of twelve, plus one month’s rent payable when the next tenant signs), which argues for saving a good tenancy that hit a bad month. It argues just as hard against dragging out a dead one: a tenant who has stopped paying and stopped answering costs more each month than a clean exit and a re-let does.
Screening is the real answer
Every step above is damage control. The tenancy that never misses a month was mostly decided earlier, at screening: how long they expect to stay, who the employer is, whether a company signatory stands behind the lease, and whether the answers hold together.
Tenant quality shows up as maintenance load, message volume and vacancy — payment behavior belongs on that list too. It is why tenant sourcing screens for stability rather than for the highest headline rent, and why the fee only bills when a tenant actually signs.
One more case belongs here because it looks identical from abroad: the rent is fine, but the reporting stopped. If the person you cannot reach is the manager rather than the tenant, that is a different problem with its own playbook: switching property managers without losing the tenant.
Common questions
Can I keep the whole deposit if the tenant stops paying?
The lease decides, not the mood. Arrears offset against the deposit with documented amounts, and deductions beyond arrears — damage, unpaid bills — stand on records: the condition baseline, meter readings and invoices.
How quickly would I find out my tenant missed a month?
In the statement for that month, marked as what it is. A statement that goes quiet exactly when something is wrong is the bigger warning sign than the missed payment itself.
Does a corporate tenant reduce the risk?
It changes who stands behind the rent: a company signatory rather than an individual's cash flow. Screening still asks the stability questions — how long the posting is, who approves the lease — because a transferred employee ends a tenancy as surely as a missed payment.
