The Non-US Buyer's Complete Guide to Purchasing Luxury Real Estate in Miami

Miami's luxury market is fundamentally international — roughly 60% of buyers at the $3M+ price point are foreign nationals. But the process of buying US real estate as a non-citizen is meaningfully different from domestic acquisition: FIRPTA withholding, treaty elections, entity structuring for asset protection, and the FBAR reporting obligations that many foreign buyers discover only after closing. This is the guide we wish existed when we started working with international clients.

South Florida's luxury market does not move on national-headline cycles. It moves on family-office allocation decisions, foreign-buyer currency flows, and the specific micro-supply of branded residences coming on line in any given quarter. The Santiago Group tracks all three weekly because the decisions our clients make at the $5M-and-up price point hinge on local data, not national narratives.

For international buyers, the most reliable framing is to start with absorption rate — how many months of inventory exist at the current sales pace — then layer in the days-on-market trend for the last 60 days, then look at the spread between list and close. National "luxury index" reports rarely slice the data this way, and they routinely miss the inflection points that matter for clients positioning over a 12-month horizon.

"The Non-US Buyer's Complete Guide to Purchasing Luxury Real Estate in Miami" is a question that surfaces frequently in our consultations with prospective buyers and sellers. The honest answer depends on three inputs: where you are in the buy/sell cycle relative to your own life events, what specific submarket you are exposed to (Fisher Island and Bal Harbour do not move together), and how patient your capital is. Generic market advice fails most clients at this price point — granular, micro-level analysis does not.

Our practice is built around what we call the "informed buyer" thesis: the clients who do best long-term are the ones who treat real estate as an investment-grade asset with relationship-driven access, not a transaction. We protect that thesis with a strict client-count cap, a research desk that reads every comp closing within 48 hours, and a private network of off-market introductions we built twenty years of representing this segment.
