When buying a Grand Marina Saigon branded residence to let, the key question is not "which unit is the prettiest" but "which unit fills fastest and keeps the most stable cash flow". In Ba Son, District 1 — where the tenant pool is dominated by foreign professionals (expats), senior managers and international families — each layout serves a different renter. This guide ranks the unit types by their real rental appeal, using market-reference data, so you can weigh your options before deciding.
Which Grand Marina unit rents best?
The one-bedroom (1BR) is usually the "safest" rental play thanks to its lower entry price, deep pool of single and couple expat tenants and high letting liquidity, while the 2BR delivers larger absolute cash flow and longer-staying tenants.
There is no single right answer for everyone: "best" depends on your budget, risk appetite, and whether you prioritise percentage yield or absolute cash flow. That said, based on how the luxury rental market behaves in District 1, a rough ranking looks like this:
- 1BR (~50–60 m²) — highest letting liquidity, lowest capital outlay, typically the best percentage yield.
- Dual-Key — most flexible: live in one part and let the other, or split into two separate tenancies.
- 2BR (~70–90 m²) — high absolute cash flow, family expat tenants, stable long-term leases.
- 3BR (~110–140 m²) — a narrower tenant pool, but when matched (executive families, business leaders) the rent and tenant loyalty are strong.
How to read this ranking: if you want an easy-to-let unit at a moderate price, lean toward the 1BR; if you want a larger rent cheque with fewer tenant turnovers, lean toward the 2BR; and if you want to live in part and let part, the Dual-Key is the option most worth a serious look.
Why does the 1BR usually deliver the best rental yield?
The 1BR has the lowest entry price yet still carries the full Marriott brand and services, so its rent-to-price ratio (yield) tends to be higher than that of larger units.
The core 1BR tenants in District 1 are single foreign professionals or child-free couples working in the financial centre, the Thu Thiem area, or multinational firms. They value location, security and service over floor area, so a 1BR of roughly 50–60 m² right beside Ba Son Metro station (only ~250 m from the project) is a very well-sized product.
Because the indicative entry price for a 1BR starts from around VND 20 billion — far below a 2BR (from ~35 billion) or 3BR (from ~60 billion) — the same budget can buy more 1BR units and spread your vacancy risk. If you are still weighing the two most popular layouts, read our deeper comparison in Grand Marina 1BR vs 2BR: Which Unit Should You Buy? to understand each one's strengths and trade-offs.
When should you choose a 2BR to let?
The 2BR fits when you prioritise larger absolute cash flow and want family expat tenants on long-term leases who turn over less often.
Foreign families with one young child, or couples who need a home office, typically look for a 2BR of around 70–90 m². This group tends to stay longer (over a 2–3 year posting), pays reliably and causes less wear. In return, the 2BR's absolute rent is higher than a 1BR's, though its percentage yield is often a touch lower because the entry price is larger.
A real plus for the 2BR at Grand Marina is its family-friendly amenity set: the river-facing Sky Infinity Pool, a kids' pool, the Kids Club, an outdoor playground, and nearby international schools (BIS, ISSP, AIS). These help retain expat families longer and reduce vacancy.
The Dual-Key — a flexible tool for buy-to-let investors
A Dual-Key unit lets you live in one portion and let the other, or split it into two independent tenancies, making it very flexible on cash flow.
A Dual-Key is essentially two zones with separate entrances inside a single apartment. For a buy-to-let investor, that opens several scenarios:
- Live in the larger zone and let the smaller studio/1BR to offset your carrying costs.
- Let both zones to two different expat tenants to maximise total rent.
- Switch flexibly: combine the zones when the family needs more space, or split them to rent out when you need income.
Investors are increasingly drawn to this layout for its "multi-tasking" ability. To understand exactly how it works, see Grand Marina Dual-Key Units: How They Work & Who They Suit. Note that Dual-Key counts per tower are limited (for example, Lake has 44, Cove has 18), so supply is often tight.
Because Dual-Key and prime rental units sell through quickly, it's worth asking early which ones are still open.
Reference table: indicative rent & yield by unit
Per market-reference data, monthly rents run roughly VND 25–40 million for a 1BR, 40–70 million for a 2BR, and 70–120 million for a 3BR, with overall yields around 3.5–5% per year.
| Unit type | Indicative area | Indicative rent (VND million/mo) | Typical tenant |
|---|---|---|---|
| 1 bedroom | ~50–60 m² | 25–40 | Single expats, child-free couples |
| 2 bedroom | ~70–90 m² | 40–70 | Expat families with one child, couples needing a home office |
| 3 bedroom | ~110–140 m² | 70–120 | Executive families, business leaders |
| Dual-Key | Varies by configuration | Flexible (two rent streams) | Varies — depends on how you operate it |
These are market-reference figures, not commitments. The overall indicative yield is around 3.5–5% per year — actual results depend on the tower, floor, orientation, letting timing and market policy at the time. You should check the latest rental price list before modelling your cash flow.
What drives rent besides the unit type?
The tower, floor, view and fit-out quality affect rent and how fast a unit lets just as much as choosing a 1BR over a 2BR.
For the same 2BR layout, a high-floor unit facing the Saigon River or the new Thu Thiem urban area will command a clearly higher rent than a low-floor unit facing the interior. Choosing the right floor and orientation is therefore part of the rental-investment equation — see How to Choose the Right Floor & Orientation at Grand Marina so you don't pay a "view premium" your tenants won't pay back.
A major advantage of Grand Marina is that every unit is handed over fully fitted to Marriott standard: marble/engineered-wood floors, Poggenpohl/Boffi kitchens with Miele/Gaggenau appliances, Toto/Duravit/Hansgrohe bathrooms, Daikin VRV air conditioning and app-based smart home control. Expat tenants particularly value this standard, making units easier to let with lower refurbishment costs between leases.

How does the "branded residences" factor affect rent?
As Vietnam's first Marriott & JW Marriott branded residences, Grand Marina enjoys a brand-and-service advantage that helps position rents above comparable ordinary apartments in the same area.
Per market researchers such as Knight Frank and Savills (updated over 2023–2025), branded residences are typically priced around 25–35% above comparable non-branded products. This is a market reference, not a promise of any specific appreciation or return.
For expat tenants, features such as 24/7 concierge, in-residence dining from the JW Marriott kitchen, housekeeping & laundry, multi-layer security and Marriott Bonvoy benefits are genuine draws when choosing where to live.

Can foreigners let out a Grand Marina unit?
Yes — foreigners own units on a 50-year tenure (renewable under the law) and may lease and transfer them, within the cap of 30% of units per building reserved for foreign buyers.
Vietnamese buyers receive a long-term pink book with full rights to use, transfer, lease and inherit, and can borrow up to 70% from a bank. Foreigners hold a 50-year tenure (renewable under Vietnamese law), with leasing and transfer permitted and bilingual paperwork support available. This is general information; before deciding, you should review the legal documents and the specific price list for each unit.
