The shift: how international investors now research NYC real estate

For most of the last two decades, an investor in Singapore or Riyadh who wanted to buy a Manhattan condominium relied on one of three channels: a private bank or wealth manager referral, a luxury real estate broker with international offices, or a direct relationship with a developer’s sales team. All three are relationship-mediated, slow, and limited in reach.

That is changing. AI chatbots are now the first stop for a growing segment of high-net-worth international buyers. Roughly three-quarters of wealth management firms now report using some form of AI in their operations (up from approximately half just two years prior), and investors themselves are adopting the same tools their advisors use. Perplexity AI has become the preferred real-time research tool for commercial real estate professionals specifically because it retrieves current, source-cited data — not just pattern-matched responses from training data.

The consequence for the NYC luxury condo market is significant. A buyer in Dubai who opens ChatGPT and asks “what are the safest NYC condo buildings for international investors” is conducting pre-purchase due diligence via AI — often before contacting any broker, developer, or wealth manager. The buildings and firms that appear in those responses have an enormous first-mover advantage. Those that don’t appear have lost consideration entirely, without ever knowing a prospect existed.

This shift is accelerating. The NAR 2025 International Transactions report found that international buyers purchased $56 billion worth of US existing homes in the 12 months ending March 2025 — a 33.2% year-over-year increase and the first year-over-year uptick since 2017. The Manhattan luxury segment is a disproportionate share of that number. And the buyers driving the rebound are exactly the tech-forward, research-driven investors who use AI first.

Which NYC condos AI recommends to international investors

We queried ChatGPT, Perplexity, Claude, and Gemini with buyer-intent prompts representative of what an international investor would actually type: “safest NYC condo buildings for foreign buyers,” “best luxury condominiums New York City foreign nationals 2026,” “New York City condo no board approval international buyer,” and variations in the context of EB-5 program planning and pied-à-terre use. The table below maps which buildings appear, how often, the typical buyer-origin countries the AI associates with each, and a tested AI mention rate.

Building Neighborhood Starting Price (approx.) Typical Foreign Buyer Origin AI Mention Rate *
Central Park Tower (217 W 57th) Billionaires’ Row ~$7M China, UAE, South Korea ~70% of responses
432 Park Avenue Midtown ~$8M China, Middle East, Brazil ~65% of responses
220 Central Park South Billionaires’ Row ~$10M UK, Canada, Selective global ~55% of responses
One57 (157 W 57th) Billionaires’ Row ~$5M China, UAE, Singapore ~60% of responses
56 Leonard (Jenga Tower) Tribeca ~$2.5M France, UK, Australia ~40% of responses
30 Park Place (Four Seasons) Tribeca / Downtown ~$3M Middle East, Asia, Europe ~35% of responses
15 Central Park West Upper West Side ~$8M UK, Canada, Brazil ~50% of responses
70 Vestry Tribeca ~$5M Europe, Hong Kong, Australia ~20% of responses
520 Park Avenue Upper East Side ~$16M UK, Europe, Canada ~15% of responses
111 W 57th (Steinway Tower) Billionaires’ Row ~$7.75M China, UAE, South Korea ~25% of responses

The pattern is clear: the buildings with the most press coverage, Wikipedia articles, and media citations dominate AI responses. Central Park Tower, 432 Park, and One57 benefit from years of record-setting sale coverage in The New York Times, Bloomberg, and the Financial Times. Buildings like 70 Vestry and 520 Park — which are legitimately excellent choices for international buyers — appear in a fraction of responses because they generate less volume in AI training corpora.

This is not a ranking of the “best” buildings. It is a map of what AI thinks is best — and the gap between those two things is where marketing opportunity and buyer mismatch both live.

Why most new NYC condos are invisible to foreign-buyer AI queries

1. The language corpus gap

AI language models train primarily on English-language web content. A buyer researching NYC real estate from Singapore reads English fluently, but the sources they trust — regional financial press, wealth management newsletters published in Chinese, Arabic-language investment blogs — are systematically underweighted in AI training data. The result: AI’s recommendations to international buyers reflect what US English-language media wrote about, not what international high-net-worth buyers actually value or discuss. A Tribeca building that is regularly featured in South China Morning Post or The National (UAE) benefits not at all from those citations in its AI mention rate — because those publications are a small fraction of training data compared to US outlets.

2. No international source corpus

The authoritative third-party sources that most influence AI recommendations in US real estate are US-based: Zillow, StreetEasy, The New York Times real estate section, Curbed, and The Real Deal. International buyers researching Manhattan condos from abroad are funneled to generic US portals rather than to international-buyer-focused resources, EB-5 specialist legal directories, or global private wealth publications that would surface more nuanced building and developer information. Developers who publish exclusively in US outlets are invisible to buyers whose AI agent is scanning for sources their home-country wealth ecosystem recognizes.

3. US-centric training data excludes buyer-relevant context

Foreign buyers have specific concerns that domestic buyers don’t share: FIRPTA implications, LLC vs. direct ownership structures, mansion tax treatment at various price points, estate tax exposure under non-domiciliary rules, EB-5 visa eligibility, and pied-à-terre versus primary residence tax classification. AI responses to international buyer queries rarely address these topics accurately because the training data that would ground those responses — tax law updates, USCIS policy bulletins, cross-border estate planning discussions — is scattered, technical, and frequently updated in ways that outpace model training cycles. Developers and brokers who publish structured content on these exact topics create a citation opportunity that competitors are almost entirely ignoring.

4. New developments launch faster than AI learns

Manhattan’s luxury condo pipeline is active. In Q1 2026, new development contracts were up 87% year-over-year — the highest for any period this decade (Compass / The Real Deal, April 2026). New buildings entering the market cannot rely on years of accumulated media coverage to reach AI training data. If a building launched in 2024 or 2025, it is substantially underrepresented in most AI models’ training corpora, regardless of its actual quality, amenities, or foreign-buyer suitability. Without a deliberate AI-visibility strategy, new developments are nearly invisible to international buyers who ask AI first.

What AI gets wrong when a Dubai or Singapore buyer asks about NYC real estate

The errors AI makes for domestic US buyers are consequential. The errors it makes for international buyers can be financially dangerous, legally misleading, and expensive to unwind. Here are the most common categories of failure we document in Metricus testing:

Outdated prices not converted to buyer-origin currencies

AI models frequently cite listing and sales prices from training data that is months or years out of date — which creates false anchoring for any buyer doing preliminary research. For international buyers, this is compounded by currency conversion: a price cited in USD is not automatically converted to AED, SGD, GBP, or BRL, and exchange rates fluctuate materially. A unit that appeared to be priced at X AED based on a training-data USD price may be substantially different at current exchange rates. We have seen AI responses to Middle Eastern buyer queries cite Manhattan prices from 2022–2023 with no caveat about market movement or currency context.

Wrong FIRPTA guidance

FIRPTA (the Foreign Investment in Real Property Tax Act) requires a buyer to withhold 15% of the gross sale price when purchasing from a foreign seller, which is remitted to the IRS. This is a seller-side imposition, not a buyer cost — but AI frequently conflates it, framing FIRPTA as a buyer tax or misquoting the withholding rate. The current rate is 15% of gross sale price (reduced to 10% only for sub-$1M properties where the buyer will use the property as a primary residence). AI systems trained on older documents sometimes cite the previous 10% rate as the standard, or omit FIRPTA entirely when describing foreign buyer costs.

Pied-à-terre tax confusion

No pied-à-terre tax is currently enacted in New York as of April 2026. The proposals that circulated in the New York State legislature — which would have imposed annual taxes on high-value non-primary-residence condos — did not pass. AI models trained on 2019–2021 web content, which included substantial coverage of these proposals, sometimes tell international buyers that a pied-à-terre tax exists and would apply to their purchase. This directly and incorrectly raises the perceived holding cost of Manhattan real estate for international investors.

Co-op vs. condo confusion

Approximately 75% of Manhattan residential units are co-ops — a legal structure involving share ownership in a corporation, not individual property title. Co-op boards routinely reject foreign nationals, non-primary-residence buyers, and LLC purchasers. Condominiums, by contrast, allow foreign nationals to purchase with no board approval and no restrictions on pied-à-terre use. This distinction is fundamental to any international buyer’s NYC strategy. AI responses frequently blur the line, recommending buildings without distinguishing whether they are co-ops or condominiums, or providing inaccurate characterizations of which buildings allow foreign ownership.

Estate tax exposure understatement

The US federal estate tax exemption for resident US persons is $13.99 million in 2025 (rising to approximately $14.6 million in 2026 under TCJA adjustments). For non-resident foreign nationals, the exemption is only $60,000. A foreign national who owns a $5 million Manhattan condo at death faces estate tax exposure on approximately $4.94 million at rates up to 40%. AI responses rarely surface this disparity. International buyers who rely on AI for estate planning context — without independent tax counsel — are exposed to a materially underestimated risk.

The AI accuracy problem for international buyers: Every error above represents a category where a developer, broker, or legal firm that publishes accurate, current, structured content on international-buyer tax and legal topics gains a durable citation advantage. The gap between what AI says and what international buyers need to know is a content opportunity that is almost entirely unclaimed.

The foreign-buyer market in 2026: numbers and trends

The NAR 2025 International Transactions in US Residential Real Estate report — covering April 2024 through March 2025 — is the most comprehensive recent data on foreign buyer activity. Key findings:

  • International buyers purchased $56 billion worth of US existing homes in the 12-month period, a 33.2% year-over-year increase and the first such increase since 2017.
  • Buyers purchased 78,100 properties, up 44% from the prior year.
  • The median purchase price for foreign buyers was $494,400 — a record high.
  • 47% of international buyers paid cash, compared to 28% among all buyers.
  • China was the top country of origin by purchase volume in 2025, with Chinese buyers holding the highest average purchase price at approximately $1.2 million (NAR 2025).
  • China, Canada, Mexico, India, and the United Kingdom together accounted for nearly half of all foreign purchase volume nationally.

Manhattan is a disproportionate draw within that national picture. In the first half of 2025, international buyer activity in NYC doubled on a sales-volume basis year over year (The Real Deal / Miller Samuel). Q2 2025 saw a record 69% of Manhattan transactions close as all-cash — a figure driven substantially by international buyers, for whom USD-denominated cash purchases represent both capital preservation and currency diversification (Miller Samuel / Douglas Elliman Q2 2025 report).

In Q1 2026, Manhattan’s broader market saw total residential sales fall 3.2% year over year to 2,279 closings — but the luxury segment diverged sharply. Contracts for homes priced between $10 million and $20 million jumped 47.4% from a year earlier. Ultra-luxury condo sales rose 30.0%. The $3M–$5M tranche saw 456 sales, surging 76.7% year-over-year — the highest total in over a decade (Compass Q1 2026 Manhattan Market Report). New development contracts signed in Q1 2026 were up 87% from Q1 2025, the highest new-development period this decade (The Real Deal, April 2026).

Buyer origin countries active in NYC in 2025–2026 include China (highest volume), Canada, United Kingdom, UAE and broader Gulf region, Singapore, Taiwan, Hong Kong, Brazil, South Korea, and Australia. Middle Eastern buyers posted an 85% increase in luxury real estate inquiries globally in 2025 (James Edition / Panorama Marbella buyer data). For Manhattan specifically, Asian buyers — particularly Chinese, Taiwanese, and Hong Kong nationals — are concentrated at the ultra-luxury end, with average per-transaction prices substantially above the national foreign-buyer median.

The EB-5 visa program remains an active driver of high-value condo purchases. As of 2025–2026, the minimum investment is $1,050,000 for standard projects and $800,000 for projects located in a Targeted Employment Area (TEA) — either a rural area or a high-unemployment census tract. The program requires creation or preservation of at least 10 full-time jobs for US workers. Crucially, these investment thresholds are scheduled for an inflation adjustment on January 1, 2027, making 2026 a strategic filing window for investors who want to qualify at current levels. The EB-5 program is authorized through September 30, 2027. Several Manhattan residential developments have structured EB-5 regional center offerings, making the underlying real estate project — and its AI visibility — directly relevant to how international investors discover EB-5 investment opportunities.

The buildings breaking through in 2026

The table below focuses on buildings that are actively marketed to international buyers, have the infrastructure to support foreign ownership (no co-op board, LLC-compatible, pied-à-terre friendly), and reflect the Q1 2026 market picture.

Foreign buyer share estimates based on brokerage reports and industry sources. All buildings are condominiums (not co-ops) and permit LLC, trust, and foreign-national ownership. Data current as of Q1 2026.

A note on 220 Central Park South: developed by Vornado Realty and designed by Robert A.M. Stern, 220 CPS achieved the highest residential sale price in US history when a penthouse sold for $238 million in 2019. It is technically a condominium but is known for development-level selectivity in its sales process — brokers have reported that the developer has at times declined to sell to buyers of certain nationalities regardless of financial qualification. International buyers should verify current sales policies before targeting this building specifically.

What actually works: the AI-visibility playbook for foreign-buyer marketing

Developers, brokers, and legal and advisory firms serving NYC’s international buyer market have a large and almost entirely unclaimed AI-visibility opportunity. Here is what moves the needle:

1. Publish international-buyer-specific structured content

AI systems cite content that contains structured claims, current statistics, and specific factual answers to specific questions. The GEO research from Princeton and Georgia Tech (2023) found that content with statistical citations was up to 40% more likely to be cited by generative AI systems. For the NYC international buyer market, this means:

  • Current FIRPTA guidance with the correct 15% withholding rate and applicable exceptions, linked to IRS source documents
  • NYC closing cost breakdowns for foreign buyers at key price points ($5M, $10M, $25M), itemizing mansion tax, transfer tax, and title costs
  • Comparison of LLC vs. direct ownership vs. trust structures with specific estate tax exposure numbers for non-domiciliary buyers
  • EB-5 program eligibility guides tied to specific developments, with current TEA investment thresholds ($800,000 vs. $1,050,000) and job creation requirements

2. Build citations in international-market sources

Domestic US sources dominate AI training data, but international-buyer-focused publications can still influence AI visibility if they have sufficient authority and English-language content. Priority targets include:

  • South China Morning Post real estate section (substantial readership among HNW Chinese buyers considering US property)
  • The National (UAE) property coverage
  • Financial Times Alphaville and global luxury property coverage
  • Mansion Global (a Dow Jones property with strong international HNW readership)
  • Juwai IQI (the leading cross-border Chinese property platform) and their editorial content
  • EB-5 Investors Magazine and related investment immigration publications

3. Implement FAQPage structured data answering international-buyer questions

The FAQPage schema type is directly readable by AI systems when crawling for content. A developer or brokerage website that implements structured FAQ markup answering: “Can a non-US citizen buy a condo in NYC?”, “What is FIRPTA and how does it affect foreign buyers?”, “Are there pied-à-terre restrictions on Manhattan condos?”, and “Can I buy a NYC condo through an LLC?” becomes directly citable for those exact queries — the same queries international buyers ask AI chatbots.

4. Correct AI errors at their source

If ChatGPT or Perplexity is telling international buyers that a pied-à-terre tax exists in NYC, that FIRPTA withholding is 10%, or that a specific building requires board approval from foreign nationals — those errors are coming from specific source documents that the AI learned from. A Metricus report identifies which source documents are generating incorrect AI responses about your building or firm. Fixing the source — updating an old legal blog post, correcting a stale listing description, adding accurate content to an authoritative reference page — propagates corrections into future AI responses as models retrain.

5. Create multi-language citations (English-anchored)

International buyers often use AI in English even when English is not their first language, because English-language AI responses are more accurate and comprehensive for US real estate topics. However, the sources that influence AI can include international publications that are indexed in English. A developer who issues a bilingual press release (English + Mandarin, English + Arabic) in an international media outlet creates a citation in an authoritative source that AI can index. The English content makes it citable; the bilingual context makes it relevant to international buyer intent signals.

6. Audit what AI says to buyers in each origin market

A Metricus AI visibility audit tests queries as a buyer in specific markets would ask them — including market-specific terminology, currency framing, and local regulatory context. The AI response a buyer in Dubai receives for “best NYC condo for UAE investor” is different from what a Singapore buyer receives for “New York luxury condo Singapore buyer safe investment.” Understanding those differences, what errors exist in each, and which competitors appear in each buyer’s AI responses is the foundation of a data-driven international AI-visibility strategy.

The case for auditing your international AI visibility now

The NYC luxury condo market in 2026 is defined by two converging dynamics. The first: foreign buyer volume is at its highest since before the pandemic, with international buyers now accounting for 15–18% of Manhattan high-end condo transactions and quarterly luxury volumes at decade-level highs. The second: the buyers driving that rebound are the most AI-reliant generation of international investors ever. They research on Perplexity before calling a broker. They ask ChatGPT about tax structures before engaging a lawyer.

The buildings and firms that will capture outsized share of this buyer flow are not necessarily the ones with the best properties or the most experienced teams — they are the ones whose answers appear when those buyers ask AI questions. And right now, the AI-visibility landscape for international NYC buyers is dominated by a small number of well-publicized buildings while the rest of the market is essentially invisible.

That invisibility is not permanent. It is a content problem, a citation problem, and a structured-data problem — all of which are solvable, and all of which compound in favor of early movers. Every authoritative content asset you build today enters the data that AI systems cite tomorrow. The developers and brokers who establish that citation footprint now will find that the gap between their AI visibility and their competitors’ only widens over time.

The bottom line: If you are marketing NYC luxury condos, condo developments, or professional services to international buyers in 2026 — you need to know what AI is telling those buyers about you, your buildings, and your competitors. Not next quarter. Now, while the market is active and the competitive window is open.
