OneHousing review: services, fees, pros and cons

OneHousing is a Vietnamese real estate technology platform launched in November 2020 by One Mount Group, a joint venture formed a year earlier that originally brought together Vingroup, Techcombank and Masan — three of Vietnam's largest conglomerates — under a single digital-ecosystem strategy. The platform is headquartered at One Mount Building in Times City, Hanoi, and describes itself as an online-to-offline marketplace covering the full buying and selling journey, from listings and financing calculators through to paperwork support. Its ownership has shifted since launch: Vingroup fully divested its stake in March 2022, and OneHousing today operates within a group closely tied to Techcombank, its financing partner. On the product side, its best-known differentiator is a proprietary automated home-valuation tool — Vietnam's first, according to its own materials — with results it says are accepted by partner banks as a basis for loan limits, and a secondary-market broker network that has grown to over 2,000 agents since launching in October 2023, focused heavily on reselling Vinhomes and Masterise Homes units. Vietnam's proptech sector has not been without casualties — Propzy, an earlier venture-backed platform, ceased operations in 2022 — which is worth keeping in mind when weighing a newer platform's long-term durability against its current institutional backing.

For a foreign buyer, OneHousing's relevance comes mostly through its inventory rather than a dedicated service line: because it is closely tied to Vinhomes and Masterise Homes, much of what it lists and resells sits inside the property types foreigners are permitted to buy — condominium units in large, developer-run townships, exactly the segment most likely to sit within the 30% foreign quota per building set out in the Housing Law 2023. Its home-valuation tool could, in principle, be a useful sanity-check on a resale asking price in Ocean Park or Smart City before you sign a Sale & Purchase Agreement — though we would treat it as one data point, not a substitute for your own due diligence on the title and the building's remaining quota. Where the platform is less useful for most readers of this review is financing: its headline tool calculates loan eligibility against Techcombank credit lines, but local mortgages remain largely inaccessible to non-resident foreign buyers, so the benefit realistically applies to Vietnamese residents and, potentially, Việt Kiều buyers rather than to a typical European purchaser paying in cash or financing from abroad. We also found no publicly documented desk, contact point or process specifically built for a foreign buyer working through the standard reservation-to-Pink Book sequence, which means you should expect to coordinate your own English-speaking lawyer or agency alongside anything sourced through OneHousing.
