The direct answer
Rule 506(b) and Rule 506(c) are different Regulation D pathways for private securities offerings. Rule 506(b) generally does not permit general solicitation, while Rule 506(c) permits general solicitation only if all purchasers are accredited investors and the issuer takes reasonable steps to verify accredited status. Real estate syndications using either exemption must follow the actual securities-law requirements and offering documents.
Start with solicitation and purchaser rules
The biggest practical distinction is how the offering is marketed and who can purchase. Rule 506(b) can permit a limited number of qualifying non-accredited purchasers subject to additional conditions, while Rule 506(c) requires every purchaser to be accredited.

Verification standards are different
For accredited investors in a 506(b) offering, the issuer generally needs a reasonable belief that the investor is accredited. Under 506(c), the issuer must take reasonable steps to verify accredited status; self-certification alone should not be treated as the universal standard.
Keep securities compliance separate from deal economics
A syndication can have an attractive modeled waterfall and still have separate legal, disclosure, filing and investor-eligibility obligations. Regulation D does not remove anti-fraud rules or make a private offering risk-free.
Worked example
A sponsor that wants to advertise a real estate offering broadly on public channels cannot simply label the deal 506(b). A 506(c) structure may permit general solicitation, but all purchasers must be accredited and the issuer must follow the applicable verification requirements.

Common mistakes and limitations
Do not treat 506(b) and 506(c) as marketing labels. The exemption affects solicitation, investor eligibility, verification and compliance duties.
Basic illustrative waterfall only. Actual operating agreements may include accrued/catch-up pref, return-of-capital tiers, IRR hurdles, fees, clawbacks and tax allocations.
Frequently asked questions
Can a Rule 506(c) offering accept a non-accredited investor?

Does Rule 506(b) allow public advertising?
Generally no. Rule 506(b) does not permit general solicitation, subject to the actual securities-law framework and facts of the offering.
