On the morning of September 30, SEC Chairman Paul Atkins opened a public meeting of the Commission with a clear message about private markets. In his statement, he said access to private offerings should not be limited only to people who meet financial thresholds, and the Commission considered notices on new ways for individuals to qualify as accredited investors. Those include passing an exam developed by FINRA or holding a CPA license, a CFA charter or a CFP certification. None of these is final yet, because the SEC first wants public feedback, but the direction is plain. More Americans may soon count as accredited investors, and that makes a sponsor's choice of offering rule more important than it has been in years.
Most private real estate syndication deals rely on one of two SEC exemptions, Rule 506(b) or Rule 506(c). They sound almost identical, yet they lead to very different ways of raising capital. The right choice depends on one question, which is where your next investors will come from. If they already know you, 506(b) often fits. If you need to reach people who have never heard of you, 506(c) is the rule built for that job. Our guide to 506(c) accredited investor verification covers the verification side in depth, while this post focuses on the decision itself.
506(b) vs 506(c) in Plain English
Both rules sit inside Regulation D, the set of exemptions that lets a company sell securities without registering them with the SEC. Both allow a sponsor to raise an unlimited amount of money, and both require a short notice filing with the SEC called Form D. The differences come down to who can invest, how the sponsor finds them and how much proof of wealth the sponsor collects.
Rule 506(b) is the quiet route. A sponsor may accept any number of accredited investors and up to 35 investors who are not accredited but are financially sophisticated. In exchange, the sponsor may not advertise the deal to the public, which the SEC calls general solicitation. Sponsors using 506(b) usually raise from people with whom they already have a relationship, such as past investors, colleagues and personal contacts.
Rule 506(c) is the open-marketing route. A sponsor may advertise openly on a website, on LinkedIn, in email campaigns or at industry events. Every investor must be accredited, however, and the sponsor must take what the SEC calls reasonable steps to verify that status. Under 506(b), by contrast, a sponsor needs only a reasonable belief that an investor is accredited, which is often based on a questionnaire.
Here is how the two rules compare at a glance:
- Public advertising: not permitted under 506(b), permitted under 506(c).
- Who can invest: accredited investors plus up to 35 sophisticated investors who are not accredited under 506(b), accredited investors only under 506(c).
- Standard for accredited status: reasonable belief, often a questionnaire, under 506(b), and reasonable steps to verify each investor under 506(c).
- Typical source of investors: people the sponsor already knows under 506(b), new investors reached through marketing under 506(c).
When Rule 506(b) Fits Your Real Estate Syndication
Rule 506(b) remains the workhorse of private capital. According to the SEC's Office of the Advocate for Small Business Capital Formation, companies raised about $170 billion under 506(b) in fiscal year 2024, compared with about $12 billion under 506(c), as reported by Fox Rothschild. That gap reflects how many sponsors raise capital, which is through trust built over many deals.
A 506(b) offering suits a sponsor whose investor base is loyal and large enough to fill the raise. It also suits a sponsor who wants to include a few sophisticated investors who fall short of the accredited thresholds, such as a longtime colleague or a family member with deep business experience. Sponsors who take that path should plan for extra disclosure, because investors who are not accredited must receive more detailed offering information, and securities counsel will shape those documents.
When Rule 506(c) Fits Your Real Estate Syndication
Rule 506(c) suits a sponsor whose next deal is bigger than their current network. It lets a sponsor publish the deal on a website, share it on LinkedIn, speak about it at a conference and run digital ads, all without the careful silence that 506(b) requires. For a growing sponsor, that reach can be the difference between filling a raise and extending the closing date.
The cost used to be paperwork, because verifying each investor meant reviewing tax returns, bank statements or letters from accountants and lawyers. That burden eased in March 2025, when SEC staff said a sponsor could rely on a high minimum investment, starting at $200,000 for individuals and $1 million for entities, together with written statements from each investor. As a result, many sponsors now find 506(c) far more practical than it was a few years ago.
Five Questions to Choose Between 506(b) and 506(c)
The decision becomes clearer when a sponsor works through five questions in order.
- Where will most of the capital come from? If your existing investors can fill the raise, 506(b) keeps things simple. If you need new investors, 506(c) gives you the tools to find them.
- How do you plan to market the deal? Any public promotion, including a LinkedIn post about an open offering, points to 506(c).
- Do you want investors who are not accredited? Only 506(b) allows them, up to 35, with fuller disclosure.
- What minimum investment makes sense? A minimum of $200,000 or more makes 506(c) verification fast, while a lower minimum means collecting documents or professional letters from smaller investors.
- Will you raise from investors outside the United States? A 506(c) raise can run alongside an offshore raise under Regulation S on the same deal, which suits sponsors building a global investor base.
Pairing a 506(c) Raise with International Investors
Many sponsors who choose 506(c) do so because they want to grow beyond their home market, and some take the next step abroad. Regulation S is the SEC exemption for offers and sales made outside the United States, and it can run next to a 506(c) raise on the same property. U.S. investors come in through the 506(c) track, while investors in places such as Dubai, Singapore or London come in through the Regulation S track. Our Regulation S guide explains how the two tracks work together.
Raveum runs both tracks on one sponsor platform, with investor onboarding, eligibility checks and tax reporting from the same records. U.S. investors receive K-1s, and offshore investors, who invest through a U.S. C corporation blocker, receive Form 1042-S. See how the Raveum Sponsor Program works.
Choose the Rule That Matches Where Your Investors Are
The choice between 506(b) and 506(c) is less about legal detail than about the shape of a sponsor's investor base. A sponsor with a deep circle of repeat investors can keep raising quietly under 506(b). A sponsor who needs new capital, whether from across the country or across the world, gains more from the reach of 506(c), especially now that verification is simpler and the SEC is signaling a wider definition of who counts as accredited. Start with where your next investors will come from, and the right rule usually follows.

Frequently Asked Questions
What Is the Main Difference Between Rule 506(b) and Rule 506(c)?
Rule 506(b) prohibits general solicitation and lets a sponsor accept an unlimited number of accredited investors plus up to 35 sophisticated investors who are not accredited. Rule 506(c) permits general solicitation, such as a public website, LinkedIn posts and digital ads, but every investor must be accredited and the sponsor must take reasonable steps to verify that status. In short, 506(b) trades marketing freedom for flexibility on who can invest and a lighter verification burden, while 506(c) trades that flexibility for the ability to reach new investors publicly. Both rules allow a sponsor to raise an unlimited amount of capital, and both require a Form D filing.
Can a Sponsor Advertise a 506(b) Offering on LinkedIn?
No. Public promotion of a specific offering, including a LinkedIn post, a public webinar or a paid ad, is general solicitation, which 506(b) prohibits. A 506(b) sponsor generally relies on a pre-existing, substantive relationship with each person it approaches, such as past investors or contacts known before the offering. Sponsors who want to market a deal publicly should use 506(c), and they should have securities counsel review posts, decks and web pages before anything goes live. Educational content that does not promote a specific offering is treated differently from a deal announcement, so where that line falls is a question for counsel.
How Does a Sponsor Verify Accredited Investors Under Rule 506(c)?
Under 506(c), the sponsor must take reasonable steps to verify that each investor is accredited, and the right steps depend on the facts of each investor. Common methods include reviewing tax documents such as Forms W-2, 1099 or K-1 and Form 1040 for the past two years, reviewing recent bank or brokerage statements together with a credit report, or obtaining written confirmation from a registered broker-dealer, an SEC-registered investment adviser, a licensed attorney or a CPA. In March 2025, SEC staff also said a sponsor may treat a high minimum investment, starting at $200,000 for individuals and $1 million for entities, together with written statements from the investor, as a reasonable step. Sponsors should confirm their approach with counsel.
Can Non-Accredited Investors Join a 506(b) or 506(c) Offering?
Only under 506(b). Rule 506(b) allows up to 35 non-accredited purchasers, but each one must be financially sophisticated, alone or with a purchaser representative, and the sponsor must give them additional disclosure, including financial statement information. Securities counsel shapes those documents, and the extra work is one reason many sponsors choose to raise only from accredited investors. Rule 506(c) does not allow any non-accredited investors, so a sponsor using 506(c) should confirm every investor is verified before accepting funds.
How Would the SEC's New Accredited Investor Proposals Affect Sponsors?
On September 30, 2026, the SEC voted to propose amendments that would add new ways to qualify as an accredited investor: passing an exam developed by FINRA, or holding a CPA license, a CFA charter, a CFP certification or certain FINRA licenses. These are proposals only, and the 60-day comment period starts after publication in the Federal Register, so nothing has changed yet. If adopted, more individuals could qualify, which could widen the pool of eligible investors under both 506(b) and 506(c). The SEC announcement did not describe changes to the Rule 506 conditions themselves, so sponsors should watch for the final rule and speak with counsel.
Do Both Rules Require a Form D Filing?
Yes. Both 506(b) and 506(c) offerings require the sponsor to file a short notice, Form D, with the SEC within 15 calendar days after the first sale of securities. Most states also require a notice filing and fee for Rule 506 offerings, and both rules apply bad actor disqualification standards to the sponsor and other covered persons. Sponsors usually calendar these deadlines and run the bad actor check with securities counsel before the raise begins.
Can a 506(c) Offering Include International Investors?
Yes, in two ways. A non-U.S. investor can join a 506(c) offering if the sponsor verifies that the investor is accredited, using the same reasonable steps standard that applies to U.S. investors. Alternatively, a sponsor can run a separate Regulation S offering beside the 506(c) raise on the same deal. Regulation S covers offers and sales made outside the United States and follows its own conditions, including limits on directed selling efforts in the U.S. Sponsors should have counsel design how the two tracks fit together.
