CFIUS real estate rules can affect a transaction before the parties reach the closing table. On July 29, 2026, the U.S. Department of the Treasury launched a redesigned website for the Committee on Foreign Investment in the United States, including a portal intended to support earlier engagement with the Committee. The update does not change CFIUS jurisdiction, but it is a timely reminder that foreign-investment screening belongs in acquisition planning, not only in final legal review.
For foreign buyers, U.S. sellers, developers, joint-venture partners, and capital providers, the consequence can be material. A purchase, lease, or concession involving certain real estate near covered ports or military installations may fall within CFIUS jurisdiction. Entity acquisitions can follow a different regulatory path, and a transaction that was not filed can still receive scrutiny after closing.
The central thesis is practical: an address search is necessary, but it is not a complete CFIUS analysis. Parties need to examine the investor, property, rights conveyed, asset use, ownership structure, applicable exclusions, and filing strategy early enough to protect pricing, timing, and execution.
What the CFIUS Real Estate Rules Cover
CFIUS is an interagency committee authorized to review certain foreign investments for national-security risk. The real estate regulations in 31 CFR Part 802 address certain purchases and leases by, and concessions to, foreign persons involving covered real estate. The rules are location-specific and transaction-specific. Foreign participation alone does not make every U.S. property transaction a covered real estate transaction.
Covered locations can include real estate within, or functioning as part of, specified airports and maritime ports. The regulations also cover defined areas around military installations listed in Appendix A. Depending on the installation, the relevant area may involve close proximity or an extended range. The exact definitions, installation list, boundaries, and exclusions control the analysis.
Rights matter as much as title. Part 802 identifies four property rights: physical access, the ability to exclude others from physical access, the ability to improve or develop the property, and the ability to attach fixed or immovable structures. A transaction can be covered when a foreign person receives at least three relevant rights, including through partial ownership, a lease, a concession, or a later change in contractual rights.
This means a development lease can require attention even when permits have not been issued and construction has not started. It also means that allocating rights across a joint venture or lease does not automatically remove the transaction from review.
Why a Map Result Is Only the First Screen
Treasury provides a Part 802 Geographic Reference Tool to help users evaluate an address in relation to listed military installations and other geographic features. The tool is valuable for preliminary screening, but Treasury states that it is for reference only. It is not guidance or an advisory opinion for a particular transaction.
A property inside a displayed area is not necessarily covered. Part 802 contains exclusions based on the foreign person, the transaction, and the real estate. The regulations address matters such as excepted real estate investors, certain single housing units, specified commercial-space leases, and some real estate in urbanized areas or urban clusters. Each exclusion has conditions, and urbanized-area treatment can differ when property is very close to a listed installation or involves a covered port.
A property outside an apparent Part 802 area is not the end of diligence either. Part 800 governs certain transactions involving U.S. businesses. The regulatory examples distinguish the acquisition of an empty warehouse from the acquisition of a warehouse together with personnel, customer relationships, equipment, and operating systems. The first may be analyzed as real estate, while the second can constitute the acquisition of a U.S. business.
Parties should therefore test both the geography and the transaction perimeter. Primior’s broader guide to real estate compliance across federal, state, and local rules provides a useful companion framework. CFIUS is one federal screen within a larger approval, ownership, tax, land-use, and operating environment.
Five CFIUS Due-Diligence Questions for a Real Estate Deal
1. Who is the foreign person and who ultimately controls the capital?
Identify the direct buyer, lessee, concession holder, fund, joint-venture member, parents, ultimate owners, and parties with governance rights. The analysis should not stop at the name on the purchase agreement. Ownership chains, board rights, veto rights, management authority, and contractual influence can affect how counsel evaluates the transaction.
Source-of-funds work and sanctions screening serve different purposes from CFIUS review, but the information should reconcile. Conflicting ownership charts, incomplete investor records, or unexplained capital sources can delay diligence and weaken the reliability of transaction representations.
2. What exactly is being acquired?
Separate bare land or a stand-alone building from an operating business. Inventory the property, leases, personnel, permits, licenses, customer relationships, intellectual property, data, equipment, and operating systems included in the deal. An entity interest that appears to be a property acquisition may carry business assets that shift the CFIUS framework.
Primior’s real estate due-diligence checklist for limited partners covers the financial, physical, title, environmental, zoning, and sponsor evidence that remains necessary. A CFIUS analysis supplements those tests. It does not establish asset quality, cash flow, or a defensible purchase price.
3. Which property rights transfer at signing, closing, and later stages?
Map access, exclusion, development, and attachment rights across the purchase agreement, lease, development agreement, easements, licenses, management arrangements, and joint-venture documents. Include rights that arise after approvals, funding milestones, default, or exercise of an option.
Foreign lenders also need careful structuring. Part 802 states that a mortgage or similar financing arrangement does not by itself constitute a covered real estate transaction, but the analysis can change when default or another condition creates a significant possibility that the lender will obtain a purchase, lease, concession, or relevant property rights. Deal documents should address that possibility before distress occurs.
Owners and capital partners assembling a cross-border real estate transaction can bring the asset, ownership structure, capital objective, and execution questions to Primior while engaging qualified CFIUS counsel for the regulatory analysis.
4. What does the authoritative location record show?
Record the parcel address, legal description, coordinates, boundaries, current use, proposed improvements, relevant port or installation, and the date each source was checked. A large or split parcel deserves particular care because only part of the property may fall within a covered area.
The installation list can change. Treasury’s November 2024 final rule expanded the installation list and geographic coverage. Underwriting should use the regulations and tools in effect for the transaction, not a map saved during an earlier site search.
5. How will CFIUS risk affect the contract and capital plan?
Qualified counsel should help determine whether and how to engage with CFIUS. Treasury’s submission instructions describe real estate declarations and voluntary notices, pre-filing consultations, required certifications, formal-notice fees, and the Case Management System. CFIUS does not issue advisory opinions on whether a proposed transaction is covered or raises national-security concerns.
The transaction documents should allocate responsibility for diligence, filings, information production, costs, timing extensions, mitigation discussions, confidentiality, and termination rights. Financing commitments, deposits, development schedules, and third-party approvals should use compatible assumptions. A regulatory condition that can extend closing should not sit beside debt or construction milestones that expire first.
CFIUS Risk Continues After Closing
Choosing not to file is not the same as receiving clearance. CFIUS states that it screens thousands of non-notified transactions each year using public tips, government referrals, media reports, commercial databases, and other information. In a subset of cases, the Committee formally requests information or a filing. Transactions identified through that process can require mitigation or other action when national-security risk is found.
That continuing authority changes the investment case. A post-closing review can affect operating plans, ownership rights, future financing, development timing, and exit strategy. U.S. sellers also retain an interest in a durable analysis because they may need to provide records, respond to inquiries, or participate in a remedy after proceeds have been distributed.
Primior’s real estate investment framework emphasizes basis, downside protection, capital structure, development execution, and durable demand. Those principles are directly relevant here. A cross-border buyer may be well capitalized and a property may have strong economics, yet the transaction still needs a structure and schedule that can withstand national-security review.
Make CFIUS Screening an Early Investment Gate
The redesigned CFIUS website makes official resources easier to reach, but it does not turn a complex jurisdictional analysis into a map lookup. A disciplined screen connects the investor, transaction structure, property rights, location, asset use, exclusions, filing path, and contract timetable.
The best time to identify a CFIUS issue is before pricing, deposits, financing, and development commitments become difficult to change. Parties should preserve enough time to verify facts, obtain specialized advice, structure conditions, and decide whether early engagement with the Committee fits the transaction.
Foreign investors, U.S. owners, developers, and capital partners evaluating a specific acquisition, lease, joint venture, or financing can work with Primior to assess the real estate and capital plan alongside their independent legal and regulatory advisors.
