A commercial property microsite is a website built to market one listing: its own URL, its own photography, the rent roll, and an offering memorandum sitting behind a form. Should you build one? Nobody has published evidence that they work, and almost every guide recommending one was published by a company that sells them. We build them too, which is why everything below is sourced to a document you can open.
The honest answer splits in two, and the split is not the one the vendor guides make. If you are selling a building, a microsite is a marketing decision with no measurable case behind it in either direction, and your state's advertising rules follow you onto it. If you are selling an interest in the entity that owns the building, whether that page can be publicly reachable is not a design question at all. SEC staff answered it in 2015, and the answer disqualifies the gate most deal rooms ship with.
What a commercial property microsite is
One listing, one address, one site. The same thing is sold as a single property website, a listing microsite, a dedicated listing page, or a deal room, and no standards body defines any of those terms.
The reason it is a different proposition in commercial than in residential is structural. In residential, listings flow into a cooperative feed and out to every portal and brokerage site in the market. In commercial there is no MLS, submission to a Commercial Information Exchange is voluntary, and there is no IDX to syndicate anything. Your listing reaches the market because you paid a portal to show it.
So a commercial microsite is not competing with a cooperative feed the way a residential one is. It is the only copy of the listing you control outright. That is a real argument, and it is close to the only one in this post that survives contact with evidence.
Who says they work?
Nobody, in the sense that matters.
We looked for any study connecting a dedicated property website to inquiries, qualified buyer count, time on market, price achieved, lease-up speed, or transaction probability. Across three research passes we searched SSRN, NBER, RePEc, and by name the Journal of Real Estate Research, Real Estate Economics, the Journal of Real Estate Finance and Economics, and the Journal of Property Investment and Finance, plus the research libraries of NAR, CCIM, SIOR, NAIOP and ULI. No study surfaced where we could look. The peer-reviewed journals sit behind paywalls we did not search directly, so this is not proof that no such work exists. It is that we could not find any, and neither, apparently, can the people selling the product.
That last part is the interesting bit, and it did not go the way we expected.
We loaded the marketing pages of seven companies selling single property or commercial property websites and counted quantified performance claims. One page out of seven made a quantified claim of any kind, and it was about the vendor's own scale rather than a client outcome: Buildout's "Trusted by 50,000+ brokers who run their deals in one place," with no source attached. Not one of the seven claimed a measurable result for a client. No percentage lift, no reduction in days on market, no price improvement.
We went in expecting a wall of invented statistics. What is actually there is quieter and harder to argue with: claims that cannot be checked because they are not really claims. "Capture leads." "Measure your success." "You will never lose a listing." None of it is false, because none of it is falsifiable.
The exception is Luxury Presence, whose page states that "Dedicated listing websites can drive 55% more traffic to a property compared to portal-only marketing" and attributes 38 closed deals worth $250 million plus a 30% increase in listing engagement to one agent's use of custom property websites. The page cites no study, dataset or methodology for any of those three numbers. We checked a second page on the same site and those figures do not appear there, so this is one page making three uncited claims rather than a house style.
Then there is the result that sits near the top of the search for most of these queries. The Forbes piece on single-property websites, published 25 September 2020, is not Forbes journalism. Forbes labels it in its own words on the page: "COUNCIL POST," then "Expertise from Forbes Councils members, operated under license. Opinions expressed are those of the author," then "Membership (fee-based)." The byline is Ray Pressley, described on the page as "Co-founder at Brevitas.com, Commercial Real Estate Marketplace and Platform Partner of the National Association of REALTORS®."
None of that is hidden. Forbes discloses all of it. The point is only that the most authoritative-looking source on the topic is a paid contributed post by someone who sells commercial real estate listing technology, and the disclosure sits in the line readers skim past.
We sell these too. Which is why this section is a count of what we could open rather than a claim about what works.
The rule that decides whether your page can be public
Here is the part no vendor guide mentions.
If the interest you are marketing is an interest in the entity that owns the property rather than the property itself, it may be a security. Our post on the offering memorandum covers when that line gets crossed and what it does to the document. This post is about what it does to the website.
Most private real estate raises rely on Regulation D. Rule 506(b), the traditional path, requires compliance with all of Rule 502, and 502(c) says that "neither the issuer nor any person acting on its behalf shall offer or sell the securities by any form of general solicitation or general advertising." The rule then lists what it means: advertisements "published in any newspaper, magazine, or similar media or broadcast over television or radio," and seminars whose attendees were invited by general solicitation.
Read that list again. Newspapers, magazines, television, radio, seminars. The rule that governs whether your listing website can be public never mentions websites, because it was written before there were any.
SEC staff filled the gap. Securities Act Rules C&DI 256.23, dated 6 August 2015, asks whether an unrestricted public website used to offer or sell securities is a general solicitation, and answers:
Yes. As the Commission stated in Securities Act Release No. 7856 (Apr. 28, 2000), the use of an unrestricted, publicly available website constitutes a general solicitation and is not consistent with the prohibition on general solicitation and advertising in Rule 502(c) if the website contains an offer of securities.
The qualifier at the end is the whole architecture of this decision. If the website contains an offer of securities. A page marketing a building for sale is not offering a security, and none of this reaches it. The same page offering units in the LLC that owns the building is a different object under federal law, and its public reachability becomes a condition of the exemption.
The alternative is Rule 506(c), and how it works is worth understanding rather than memorising. Rule 506(c) requires compliance with 230.501 and with 230.502(a) and (d). It does not list 502(c). The permission to advertise publicly is granted by omission, not by any clause saying you may advertise. What you accept in exchange is that every purchaser must be an accredited investor and the issuer must take reasonable steps to verify it, which is a materially heavier burden than 506(b) imposes.
There is no partial credit
Regulation D has a safe harbour for honest mistakes, and it specifically excludes this one. Rule 508(a)(2) preserves the exemption where a failure to comply "was insignificant with respect to the offering as a whole," then adds:
provided that any failure to comply with paragraph (c) of § 230.502, paragraph (b)(2) of § 230.504 and paragraph (b)(2)(i) of § 230.506 shall be deemed to be significant to the offering as a whole
Paragraph (c) of 230.502 is the general solicitation rule. The drafters named it as one of three things the forgiveness provision cannot forgive.
If the exemption fails, the offering was an unregistered sale of securities, and 15 U.S.C. 77l(a)(1) gives each purchaser the right to sue "to recover the consideration paid for such security with interest thereon, less the amount of any income received thereon, upon the tender of such security." Every investor gets the option to hand back their interest and take their money back with interest, which in a falling market is the same as saying every investor holds a free put on your deal.
That is the cost of getting the website wrong. Not a fine. The capital stack.
The checkbox does not work
This is the finding most likely to describe something you already have in production.
The way to keep a 506(b) offering off the wrong side of 502(c) is to offer it only to people you already have a relationship with. Staff has spelled out what counts. C&DI 256.31 defines a substantive relationship as one where the issuer "has sufficient information to evaluate, and does, in fact, evaluate, a prospective offeree's financial circumstances and sophistication," then closes the obvious door:
Self-certification alone (by checking a box) without any other knowledge of a person's financial circumstances or sophistication is not sufficient to form a 'substantive' relationship.
The standard deal room gate is a checkbox reading "I certify that I am an accredited investor." On its own, staff says that is not enough.
Three more from the same series shape what a gate has to do. The relationship must be pre-existing, formed before the offering commenced (256.29). There is no minimum waiting period, so nobody can tell you a fourteen day cooling-off period makes it fine (256.30). And staff is explicit that this is harder online than off: absent a prior business relationship or a recognised legal duty, it is "likely more difficult for an issuer to establish a pre-existing, substantive relationship, especially when contemplating or engaged in an offering over the Internet" (256.32).
None of that makes a gated online deal room impossible. The Citizen VC no-action letter of 6 August 2015 describes a platform that got there, and staff agreed that "the quality of the relationship between an issuer (or its agent) and an investor is the most important factor." The path exists. It runs through a real qualification process that evaluates each person before they are shown anything, not through a form field.
The Commission said much the same a quarter of a century earlier. Release 33-7856, effective 4 May 2000, described a password-restricted page that "would become available to a prospective investor only after the affiliated broker-dealer determined that the investor was 'accredited' or 'sophisticated'," and stated flatly that an issuer's "unrestricted, and therefore publicly available, Internet web site would not be consistent with the restriction on general solicitation and advertising."
Two cautions about relying on any of this. These staff interpretations are live documents: the series was revised in March 2025 and edited again on 23 January 2026, when the SEC's own update page records the withdrawal of three questions in the Rule 502 series without stating a reason. And none of it is a court speaking. Across three research passes we found no SEC enforcement action, no-action letter, or federal decision applying these rules to a real estate listing website or a portal listing specifically. This is settled guidance applied to an unlitigated fact pattern, which is a reason for care rather than comfort.
What a public page can safely carry
The same interpretations answer the practical question, and the answer is more generous than most brokers assume.
C&DI 256.24 states that "information not involving an offer of securities may be disseminated widely without violating Rule 502(c)," and that "factual business information that does not condition the public mind or arouse public interest in a securities offering is not an offer." C&DI 256.25 then draws the boundary: factual business information "generally does not include predictions, projections, forecasts or opinions with respect to valuation of a security."
Applied to a property page, that is a workable split. The building, the location, the square footage, the current tenants, the photography, the submarket, and how to reach the broker are facts. The five year pro forma, the projected internal rate of return, and the stabilised value are predictions, projections and valuation opinions, which is to say the exact contents of the sponsor deck. Facts in front of the gate. Projections behind it.
If you are only selling a building
Then almost none of the above applies, and the federal government has very little to say to you.
The one federal statute that reaches land marketing, the Interstate Land Sales Full Disclosure Act, exempts what you are doing twice over. 15 U.S.C. 1702(a)(2) exempts "the sale or lease of any improved land on which there is a residential, commercial, condominium, or industrial building," and (a)(8) exempts real estate "zoned by the appropriate governmental authority for industrial or commercial development" where the buyer is "a duly organized corporation, partnership, trust, or business entity engaged in commercial or industrial business." The regime was built for subdivided lots sold to consumers, and a commercial asset sale sits outside it.
Your state real estate commission is a different matter, and this is where a microsite quietly picks up obligations. We checked six states' advertising rules against the rule text. None of them carves commercial transactions out, and most reach a standalone property site on its face.
Texas
Florida
New York
Colorado
North Carolina
California
| State | Rule | Does it reach a single property site? |
|---|---|---|
| Texas | 22 TAC 535.155 | Yes, explicitly. "Advertisement" includes "all electronic media including email, text messages, social media, the Internet" |
| Florida | 61J2-10.025(3)(a) | Yes, and it dictates layout. The brokerage name "shall be placed adjacent to or immediately above or below the point of contact information" |
| New York | 19 NYCRR 175.25 | Yes. The definition names "websites" outright |
| Colorado | 4 CCR 725-1 Ch. 1 | Yes. Websites are Advertising, and the URL carve-out applies only where the URL is not "directly used to promote or solicit" |
| North Carolina | 21 NCAC 58A .0105(b) | Yes, through the blind ad rule. An advertisement may not be "confined to publication of only contact information, such as ... internet web address" |
| California | Bus. & Prof. Code 10140.6 | Unclear. Solicitation materials include "advertisements on television, in print, or electronic media," but the statute never says website |
Florida is the one to read closely if you build these, because it is the only rule in the set that tells you where on the page something goes. Colorado is the one people misread, because the URL exemption looks like a loophole until you notice it is conditioned on the URL not promoting anything, which a dedicated listing site does by definition.
California is a genuine ambiguity rather than a permission. The statute is broad and predates the question. We are not going to tell you it does not reach your microsite.
What we could not find out
Two questions we could not answer after three passes, stated plainly because the absence is part of the picture.
Nobody publishes independent data on how commercial buyers and tenant representatives actually find property. We went to NAR, CCIM, SIOR, NAIOP and ULI directly. The only figure that surfaced anywhere came from a company selling application software, quoted on NAR's own partner page with no methodology attached. Everyone holding a number is selling the channel that number flatters.
No trade body or bar association we could reach documents the confidentiality agreement practice. Gating the offering memorandum behind a signed confidentiality agreement is close to universal in commercial real estate, and we could not locate a single non-brokerage authority describing it as standard. It is custom, not rule, which matters if you assumed a form somewhere specified what the gate must do.
What to actually do
Decide what is being sold before you decide what the page is. Real property, or an interest in an entity. That question determines whether your only obligation is a licence disclosure or whether the page's public reachability is a condition of a federal exemption.
If any part of the deal is an entity interest, settle the exemption before the site is built. 506(b) and 506(c) produce different websites. Retrofitting a public page into a private offering is not a settings change.
Do not treat an accredited investor checkbox as a gate. Staff says self-certification alone does not create a substantive relationship. If your deal room's front door is a tickbox, it is a user experience, not a control.
Split the content the way the interpretations do. Facts about the building in front. Projections, forecasts and valuation opinions behind the qualification step.
Put the firm name and licence details on it. Every state we checked requires identification in advertising, several name websites specifically, and none exempts commercial. It costs nothing and closes the question.
Do not buy the microsite because of a number someone published. There is not one. Buy it because you want a copy of the listing that a portal cannot reprice, deprioritise or restrict, which is the argument that actually holds up in commercial.
That is the line for us as well. We build the commercial real estate websites and gated deal pages these listings live on, and we can make a qualification gate behave like a real one. Whether your deal is an asset sale or a securities offering, and what your qualification process has to evaluate, is a question for your securities counsel. If you want the build side done properly, tell us about the deal.
The short version
A commercial property microsite is a website for one listing. There is no evidence that one works. We searched the economics literature and five industry research libraries across three passes and found no study measuring any outcome, and of seven vendor pages we loaded, one made a quantified claim and none cited a source for it.
The strongest honest argument for building one is not lead generation. It is that commercial has no cooperative feed, so the microsite is the only copy of the listing you fully control.
If you are selling the building, federal disclosure law does not reach your marketing, but your state's advertising rules almost certainly reach your microsite, and none of the six states we checked exempts commercial.
If you are selling an interest in the entity, Rule 502(c) bans general solicitation, its list of examples predates the web, and SEC staff has said an unrestricted public website is a general solicitation where it contains an offer of securities. Rule 506(c) lets you advertise, by leaving 502(c) off its list of conditions, in exchange for verifying every purchaser.
Rule 508 names 502(c) as one of the failures it cannot excuse, and a failed exemption hands every purchaser the right to their money back with interest.
And the checkbox on your deal room does not create a relationship. Staff said so in 2015, in one sentence, and it is still there.
