506(b) vs 506(c): what it means for you as an investor

Why some deals are advertised and others aren't, what accreditation verification involves, and what changed in 2025.

Short answer

Most private real estate deals use Rule 506(b) or 506(c) of Regulation D. In 506(b) deals the sponsor can't advertise publicly, can accept up to 35 sophisticated non-accredited investors, and usually relies on your self-certification. In 506(c) deals the sponsor can advertise, but every investor must be accredited and the sponsor must take reasonable steps to verify it. Since March 2025, SEC staff have said a $200,000 minimum investment plus written representations can count as reasonable verification for individuals.

Key takeaways

  • Seeing a deal advertised publicly almost always means it's a 506(c) offering.
  • 506(c) requires verification; expect tax documents, a CPA or attorney letter, or (for higher minimums) written representations.
  • About 94% of Rule 506 capital still goes through 506(b).
  • The exemption doesn't make a deal safer or riskier. The sponsor and terms do.

  • You confirm in writing that you're accredited and that no third party is financing your minimum investment.
  • The sponsor must not know of facts suggesting otherwise.
  • For lower minimums, expect traditional verification: tax returns, bank or brokerage statements, or a letter from a CPA, attorney or broker-dealer.
  • This is SEC staff guidance, not a rule change.

What this means for your diligence

  • A publicly advertised deal isn't a scam by default; 506(c) allows it. Vet the sponsor the same way.
  • Be wary of 506(b) sponsors cold-pitching you a specific deal with no prior relationship.
  • Keep verification documents ready to speed up 506(c) investments, and share them securely.

Frequently asked questions

Sponsors using Rule 506(c) can advertise publicly but must verify every investor is accredited. Sponsors using 506(b) cannot generally solicit and must have a pre-existing relationship with investors.

Typically recent tax returns or W-2s for the income test, or bank and brokerage statements plus a credit report for the net worth test, or a verification letter from a CPA, attorney or broker-dealer. For $200,000+ minimums, written representations may suffice under 2025 SEC staff guidance.

No. The exemption affects marketing and verification, not investment quality. Evaluate the sponsor, terms and business plan.

Only in some 506(b) offerings, up to 35 sophisticated non-accredited investors, and the sponsor must provide extensive disclosure. Many sponsors choose to accept only accredited investors.
