Why do studios gross 8.70% while three-bedrooms gross only 4.15%?

Rent is priced more by the room than by the area: an extra bedroom adds far less rent than price, so the larger the unit, the thinner the yield. Investors crowding into small units is the result of that slope — and it also means small-unit prices already capitalise yield-chasing, so 8.70% is a pre-purchase ratio, not a post-purchase promise.

Against the Vietnam serviced-apartment entry (No. 8), where does Bangkok win?

On title and exit: foreign freehold in your own name plus a deep resale market. It loses on net yield (the Vietnam entry's basis runs higher, with higher friction and management intensity to match). If the goal is pure cash flow, neither belongs ahead of the listed REITs; if the goal is "asset plus own-use option", Bangkok condo title quality is something Vietnam cannot match.

Why single out juristic fees?

Because they are charged per sqm regardless of occupancy: in a vacant month rent is zero and the fee is still due, worst in small units in high-fee buildings. When computing net yield, annualise the fee and divide by price first — in buildings where that exceeds about 0.8 points, the net yield rarely looks good.

Bangkok condo buy-to-let, taken apart: 5.93% gross, about 4% net — and the serviced-apartment money is not yours

The Thailand chapter of this site's gross-versus-net series. The gross figure is real: Bangkok condos average a 5.93% gross rental yield (Q3 2026, Global Property Guide with DDproperty), with a steep unit-size gradient — studios 8.70%, one-bedrooms 7.26%, two-bedrooms 6.26%, three-bedrooms just 4.15%. The net figure, on the same research house's guidance (vacancy, juristic fees, about a month's rent of agent commission, repairs), is about 3.9–4.4% for the city average before personal tax. The agent version pastes serviced-apartment numbers onto single units: downtown serviced apartments run 84.8% occupancy at Grade A rents of THB 1,261/sqm/month (CBRE) — but those are earned by licensed whole-building operators (Ascott-grade) employing housekeeping and brand systems; a single condo owner letting for under 30 days without a hotel licence breaches the Hotel Act and most juristic-person rules, so that money is neither earnable nor legal for them. Against this site's Vietnam serviced-apartment entry (No. 8): gross yields are similar on paper, Bangkok's net is lower but cleaner; Bangkok's real advantages are not yield but title (foreign freehold in your own name within the 49% quota) and exit liquidity. Verdict: below the bar as an explainer — about 4% net plus all the burdens of physical property does not clear a cash-flow board's bar — but worth a page for why small units show high gross yields, and why serviced numbers must never be annualised onto a single unit.

Why we think it makes money

It is the only physical property a foreigner can hold in Thailand in their own name: land no, villas no (lease or company structures only), condos yes — within quota and with FET-documented remittance. That title advantage deserves a page that also maps its limits.

The unit-size gradient is the best yield lesson available: the slope from 8.70% (studios) to 4.15% (three-bedrooms) shows that "yield" is never a city attribute but a product attribute — anyone buying a large unit for yield bought the wrong product on day one.

The serviced-apartment transplant is a regional sales script (the Vietnam entry has the same disease): whole-building operator rents annualised onto single owners. Bangkok's data — CBRE's whole-building basis beside GPG's single-unit basis — is enough to puncture it on one screen.

How to actually get in

Direct purchase for long-term letting: one-bedrooms around Rama 9/Ekkamai run about THB 3–6M, Sukhumvit-core THB 6–12M (portal compilations, broker basis). Check three things: the building's remaining foreign quota (written juristic confirmation), the FET remittance path, and the juristic fee per sqm.
The short-let/serviced route is closed to single-unit owners: no letting under 30 days without a hotel licence — any short-let assumption inside a yield model should simply be deleted.

What it costs, what it earns

Costs & taxes, item by item:

Juristic (common) fees: charged per sqm regardless of letting — vacant months hurt twice.
Agent commission of about a month's rent per letting, plus re-letting vacancy; furniture and appliance depreciation is material in high-turnover small units.
Tax and transfer: rental income tax (non-resident withholding at source is commonly applied around 15% in practice — verify); purchase-side transfer fee, stamp duty and specific business tax commonly total about 5–6% (split negotiable case by case).

Basis: this site uses full-cost net returns only — income minus vacancy, management, maintenance, taxes and insurance, then financing interest, with entry costs in the denominator. See the methodology。

Risks: what could go wrong

This entry is itself the risk statement: about 4% net (pre-tax) with all of physical property's burdens (vacancy, repairs, juristic-fee inflation, baht) does not rank into this board's actionable zone. Its surviving justifications are title and the own-use/exit option — consumption decisions, not cash-flow investments. If these happen, our take changes: If Bangkok net yields rise structurally above 5.5% (research basis, two consecutive years), this entry is re-based.

Quota risk crystallises at exit: in popular buildings whose foreign quota is exhausted, your buyer pool shrinks to Thais (or discounted leasehold buyers) — the liquidity discount is invisible at purchase and collected in full at sale. If these happen, our take changes: None (per-building check).

Supply keeps landing along new transit sections: small-unit completions press both rents and prices at once, so the studio gross yield of 8.70% (a ratio of standing rents to standing prices) can hold while absolute income falls. If these happen, our take changes: None (tracked by district).

What we have not verified yet

The following key figures have not yet been verified; the reason is noted for each item.

The 3.9–4.4% net is a modelled range on the research house's deduction guidance: per-unit juristic fees and vacancy vary too widely for a case figure.
Portal-compiled district prices (about THB 125,000/sqm median asking) are asking bases, not registered transactions, and are labelled as such wherever used.
