Put police registration (Form NA17) in the lease
Make your landlord's Form NA17 registration a written condition before you pay a deposit.
Your landlord is legally required to register you with the local police. Get that obligation in writing before money moves: an unregistered address complicates visa paperwork, bank accounts and any dispute you later have with the landlord.

Insist on a bilingual lease
It should spell out the electricity rate, deposit terms and notice period.
The Vietnamese column governs in a dispute, so read both. Three lines cause almost every argument: the per-kWh electricity rate, exactly what the deposit may be withheld for, and how much notice each side owes.

Check flood history, construction and noise
Do it before you sign anything — ask neighbours, not just the agent.
Look at the street rather than the apartment. Da Nang floods, and a ground-floor unit two blocks from a canal behaves very differently in October. Also check what is being built next door: sites start at six in the morning.

Don't accept a flat electricity rate
Overcharging above the official EVN tariff is now a fineable offence.
Landlords routinely quote a round number per kWh well above the state tariff, and on a year-long lease with air conditioning that is real money. Ask to see the meter and the EVN bill, and pay the tariff.

Don't pay a finder's fee or a remote deposit
Never send a deposit before an in-person viewing or a live video walkthrough.
Listings are free to browse and agents are paid by the landlord, so a fee charged to you is a fee invented for you. Photo sets get recycled between units — insist on seeing the actual apartment, live, before any transfer.
