Undersun Estate Co., Ltd., a full-service real estate agency in Phuket, works with international buyers across the full island market, from studio condominiums to ultra-premium villas. Around half of its clients complete the purchase without travelling to Thailand. Every property the agency offers passes a five-stage verification, and the agency runs the transaction end to end, from shortlist to registration at the Land Department.
Remote buyers handle reservation, contract signing by power of attorney and payment coordination from home, with recorded walkthroughs and live tours standing in for site visits. The five-stage verification covers developer corporate documents, developer track record, project and unit documentation, a physical inspection of the construction site or showroom, and review of the transaction documents.
Foreign buyers have two routes, freehold and leasehold. A condominium unit can be bought freehold within the 49% foreign quota: under Thailand’s Condominium Act, foreign owners may collectively hold up to 49% of the total saleable floor area of a registered condominium building. The alternative is a registered lease. Thai law caps a registered lease at 30 years, and agreements commonly carry contractual options for two further 30-year terms, which bind the original lessor without a statutory guarantee behind them. A villa can be held either way, and the building itself is registered in the buyer’s name, while the land beneath it is available to foreign buyers on a lease. A lease can be assigned on resale and passed to heirs where the agreement provides for it and the terms are registered accordingly. Undersun Estate sets out the applicable route before the buyer commits.
The agency also maintains a proprietary pricing archive on Phuket projects dating back to 2018. It uses the archive to track how prices have actually moved across market cycles, which areas and projects appreciated, at what pace and on what drivers, and applies that history when assessing which projects carry the stronger upside.
“We hold price data on Phuket projects going back to 2018, so we can see how the market actually moved through several cycles, which locations appreciated, which projects lagged, and what drove it,” said Bogdan Dyachuk, CEO of Undersun Estate. “That is what tells a buyer where the upside is.”
Undersun Estate’s transaction volume has grown at an average of 50% a year since 2022. Repeat buyers and client referrals account for 30% of its deals. The Thaiger, one of Thailand’s largest English-language news outlets, ranks the agency fourth in its guide to Phuket real estate agencies.
The agency holds more than 500 new-build developer properties and over 200 resale listings at any given time. Developer condominiums run from 2.52 million baht for a studio, about $76,000, to 339 million baht for a penthouse, about $10.3 million. Developer villas run from 13 million baht, about $394,000, to 265 million baht, about $8 million. Houses and townhouses start at 4.75 million baht, about $144,000. Dollar figures are approximate conversions at July 2026 exchange rates.
The largest single transaction to date is 15 units bought by one client in one deal.
“Buying a large block of units in a single development is a strong investment strategy,” said Bogdan Dyachuk. “It lets us negotiate a significant discount from the developer for the client, and that noticeably raises the projected ROI on the portfolio.”
Full deal support runs from shortlist to registration at the Land Department, covering property selection against the client’s budget and investment goals, projected ROI calculations, property viewings, review of title documents and contracts, and payment support. The team works with clients in English, Russian, Ukrainian and Thai. On the seller side, the agency syndicates listings to more than 110 property portals in over 80 countries. Current listings and market guides are published on Undersun’s website.
