Is Silom a good place to buy a condo? For rental income, yes. For a fast resale profit, less so. Silom has two rail lines, blue-chip tenants and a settled expat base, and a one-bedroom yields about 5.1% net. This guide uses our own building, Ashton Silom, to show the real numbers.
Short Answer: Yes—for rental income, but not for rapid capital appreciation.
Silom is a strong choice for condo buyers seeking stable rental income rather than short-term capital gains. The area benefits from two rail lines, a large base of professionals working for established companies, and a long-term expat community that supports consistent rental demand. One-bedroom condos typically deliver attractive rental yields, while larger luxury units generally offer lower yields and are better suited to owner-occupiers. Overall, Silom is best for investors looking for reliable rental returns from a prime CBD location.
Why Silom is Bangkok’s most connected address
Silom sits in Bang Rak, Bangkok’s original business district. What makes this location unique is its exceptional connectivity.
Two rail lines, one address
Silom is one of Bangkok’s most connected condo locations, with access to two major rail lines: the BTS Silom Line and MRT Blue Line. BTS Chong Nonsi and BTS Sala Daeng are located along Silom Road, with Sala Daeng providing a direct interchange to MRT Si Lom. From this central address, residents can easily reach Sathorn, Siam, Sukhumvit, and Bangkok’s old town without relying on a car. For tenants who prefer convenient urban living, strong transport connectivity is one of Silom’s biggest advantages.
What is within walking distance
A condo is only as good as its walk to the station. Ashton Silom is at 166 Silom Road, on Soi Silom 12, about 350 metres to BTS Chong Nonsi. That is a five-minute walk via Exit 3, so this is a condo near BTS Chong Nonsi you can use daily without a car. Banks, food and offices sit within the same short radius.
What residents actually say
On Reddit, residents describe it plainly. It is “very LGBTQ friendly” and a “10-minute bike ride to ICONSIAM and Lumpini.” The most useful comment we found: “most of the foreigners living in this area have been living here for years.” That tells you more than any yield figure. Silom tenants settle, so turnover stays low. For a landlord, low turnover is quiet money.
Who rents in Silom, and why demand holds
Three groups keep demand steady.
The financial district tenant
Silom is where the banks are. Bangkok Bank, HSBC, Standard Chartered and Bank of China sit nearby, with office towers like CP Tower and United Center. These employers bring salaried professionals who want a short commute and can pay for it. Around 155 units are listed for rent nearby, so the market is liquid, not thin.
The Japanese corporate cluster
Silom is quietly one of Bangkok’s Japanese hubs. Thaniya Street is known as Little Tokyo, Don Don Donki opened here in 2023, and Ashton Silom is a joint venture with Mitsui Fudosan, a Japanese developer. None of that is a coincidence. Japanese firms post staff to Silom, who need homes near the office.
Why the expat base is stable
Put those together and you get an unusually settled foreign community, rare in a city where expat areas turn over fast. Long tenancies beat a higher rent that ends in a year.
Understanding Condo Prices and Rental Potential in Silom
Silom is one of Bangkok’s premium CBD locations, where condo prices are shaped by more than just unit size. Location, connectivity, building quality, and unit characteristics all play an important role in determining value.
Prime CBD Location
Silom benefits from being one of Bangkok’s established business districts, surrounded by offices, financial institutions, hotels, restaurants, and lifestyle destinations. This creates consistent demand from both residents and tenants.
Transport Connectivity
Access to BTS and MRT stations is one of the strongest value drivers in Silom. Condos within walking distance of mass transit typically attract stronger demand because residents can enjoy convenient car-free living.
Unit Type and Size
Smaller units, especially one-bedroom layouts, often appeal to investors because they match the demand of professionals, expatriates, and urban renters. Larger units tend to attract buyers seeking more space and lifestyle value.
Building Quality and Position
Factors such as building age, facilities, floor level, views, and maintenance standards can significantly influence pricing within the same location.
Rental Potential: Why Silom Continues to Attract Tenants
Silom remains a strong rental market because it serves multiple tenant groups with different lifestyle needs.
Corporate Professionals
Silom and nearby Sathorn are home to many multinational companies, financial institutions, and business headquarters. Professionals working in the area often prioritize convenience and shorter commute times.
Expats and Long-Term Residents
Silom has an established international community, supported by international schools, hospitals, restaurants, and lifestyle amenities. This creates stable demand from tenants who prefer well-connected central locations.
Urban Lifestyle Renters
Young professionals and city residents are attracted to Silom because they can easily access workplaces, shopping areas, dining destinations, and entertainment without depending on a car.
Silom condos are attractive for buyers seeking stable rental demand and long-term value. While smaller units often provide stronger rental potential, larger luxury residences are better suited for buyers prioritizing lifestyle and space. The best investment choice depends on whether the goal is rental income, personal living, or long-term asset value.
Can a foreigner buy in Silom?
Yes, with one rule to check. Thai law lets foreigners own condo units outright on a freehold basis, meaning you own the unit itself for good, not a lease, but only up to 49% of the floor area of any single building. This cap, called the foreign quota, comes from Thailand’s Condominium Act (Section 19), and the other 51% stays in Thai ownership. Ashton Silom is freehold, so a foreign buyer can hold the unit in their own name. Before you commit, confirm the building’s foreign quota still has room. Ask the seller or the juristic office (the building’s management office) for the current percentage. If it is full, you would buy through a Thai leasehold or company structure instead. Our foreign ownership rules guide covers the paperwork, and many units here are sold furnished, which suits an overseas buyer.
Will the price go up? Capital appreciation
Here is the honest part. As a Bangkok CBD address, Silom is a mature, built-out district. That is good for rent and less exciting for capital growth. Do not expect the fast price jumps you see in newer Asian markets, or on Bangkok’s outer lines where a new station can reprice an area. Silom is already connected, central and expensive per sqm. Most of that growth has happened. You are buying stability and reliable rent, not a quick flip. If you need a big gain in three years, Silom is the wrong bet. If you plan to hold and collect rent from a central address in lasting demand, it is one of the safer ones.
Silom vs Sathorn: which should you buy?
Silom and Sathorn sit side by side and get lumped together, but they are not the same buy. Sathorn is more corporate and often a touch cheaper per sqm, which is why some Silom yield figures are really Sathorn numbers. Silom has the retail, the food, the nightlife and the Japanese cluster, which gives a landlord a broader, more settled tenant base. Ananda does not build in Sathorn, so if you like this side of town, our nearest project is Culture Chula , a short ride toward Samyan. If you see a headline yield of 5 to 6%, check it is not really a Sathorn unit first.
Case study: Ashton Silom
We use our own building as the worked example, with real data. It sits among Ananda’s luxury condominiums.
The building
Ashton Silom was completed in 2018. It is 48 storeys, 428 units and 309 parking spaces, at 166 Silom Road, See current units and floor plans on the Ashton Silom page.
What is different about it
It is a joint venture between Ananda and Mitsui Fudosan of Japan, with a design the architects call “Vertical Interlocking” and ceilings up to 3.6 metres in places. That partnership is not just branding. It ties the building to the Japanese tenant base above.
Who it suits, and who it does not
It suits a buyer who wants a central, freehold unit with a stable tenant and accepts a modest yield for a blue-chip location, including Japanese or long-stay expat owner-occupiers. It does not suit someone chasing fast capital growth or the highest yield, who would do better in a cheaper outer-line building.
For those seeking a condo investment in Silom, Ashton Silom offers an opportunity to own a residence in a prime CBD location with strong rental demand and long-term value potential.
