Switch From 506(b) to 506(c) on Your Next Deal

Yes, a sponsor can raise one deal under Rule 506(b) and the next under Rule 506(c). The exemption is chosen offering by offering, not once for a sponsor. What changes on the 506(c) deal is who can invest (only accredited investors, and you must take reasonable steps to verify it), how you may find them (general solicitation is allowed) and the paper trail you keep. DoorRaise supports both exemptions, and this post covers the switch.

This post is part of our guide to real estate syndication. For the first-time choice, read 506(b) vs 506(c). This one is for sponsors who already raised under 506(b). Rules are as of October 2026.

When does switching make sense?

You want to...	506(b)	506(c)
Post the deal publicly, run ads, speak at events	No general solicitation	Allowed
Take non-accredited investors	Up to 35, who must be sophisticated and receive added disclosure	None
Rely on a questionnaire alone	Yes, if you reasonably believe the investor is accredited	No, you must verify
Reach new people with no relationship	Hard to do	Yes

The usual reasons to move to 506(c) are a bigger raise than your network can fill, a plan to run webinars or ads, or a wish to stop screening for "substantive relationship." The usual reasons to stay on 506(b) are a base of existing investors, including some non-accredited, and a wish to avoid verification friction. For the rule text, see 17 CFR 230.506.

Can I change an offering from 506(b) to 506(c) after I have started?

Be careful. General solicitation under 506(b) can destroy the exemption, and the safe way is to decide before you speak publicly. Moving an offering that is already open is a question for your securities attorney, because what you have said and to whom matters. For a new deal, the clean answer is to choose 506(c) from the start and keep your communications consistent with it. Our post on what counts as general solicitation lists the activities that matter.

What happens to your existing investors?

Your past investors can still invest if they are accredited, but each one must be verified for the new deal. How to verify:

Documents. Tax returns, W-2s, bank or brokerage statements, or a credit report, depending on the basis for accredited status.
A third-party letter. From a registered broker-dealer, SEC-registered adviser, attorney or CPA. See the CPA accredited investor letter.
High minimum plus statements. In March 2025 SEC staff said a minimum investment of $200,000 for a person (or $1,000,000 for an entity) plus written representations that the money is not borrowed for the purpose can count as reasonable steps. That is staff guidance, not a rule, and it has conditions. See accredited investor verification.

The non-accredited friend who invested last time is the hard case. They cannot join a 506(c) deal. Plan how you will explain that to them, or keep a separate 506(b) offering for them, with the integration rule in mind.

How does the integration rule affect the timing?

Offerings can be treated as one if they are close in time and similar. Rule 152 lays out a general principle and safe harbors. One of them covers offerings that are at least 30 calendar days apart, and it carries a condition when the earlier offering barred general solicitation and the later one allows it: the issuer must reasonably believe each purchaser in the later offering was not solicited through general solicitation, or had a pre-existing substantive relationship before the offering started. Read 17 CFR 230.152 with your attorney. Our post on integration of offerings explains it in plain terms.

What changes in the documents and the investor experience?

Offering documents. The subscription agreement and the offering summary must say which exemption applies. A 506(c) subscription agreement has the investor represent that they are accredited and that they provided verification.
Marketing. Anything you say publicly becomes subject to the antifraud rules, which apply to every offering. See what you can say about a deal and Rule 10b-5.
Form D. You check the 506(c) box. See how to fill out Form D.
Timeline. Verification adds a step before money moves. Build it into the schedule, and let investors start it as soon as they commit.

A short decision checklist

How many investors do you need, and can your network supply them?
Are any of your likely investors not accredited? If so, 506(c) excludes them.
Are you willing to run verification for every investor?
Do you want to advertise? If yes, 506(c).
Is another offering open, or planned within 30 days? Check integration.
Have you written down why you chose the exemption?

The 506(b) or 506(c) guide walks through the first three questions in a few clicks.

How DoorRaise fits in

DoorRaise is a technology platform, not a law firm, broker-dealer, investment adviser or funding portal. For each deal it generates the offering documents for the exemption you pick, runs accredited investor checks on every investor, handles e-signatures and tracks wires into escrow at Enterprise Bank & Trust. Fees are $1,500 to set up (non-refundable), $5,000 at closing (only if the deal closes) and $3,500 a year. DoorRaise takes verified accredited investors only, so non-accredited investors are covered here as general law, not as a feature. Investing can lose money, and no exemption makes a deal safer.

Raise your apartment deal from the people who already follow you.

DoorRaise is built for apartment buildings with 5 or more units: one link for the deal, escrow until closing and a standard fee card.

FAQ

Can I use 506(b) for one deal and 506(c) for the next?

Yes. Each offering relies on its own exemption. Keep the offerings separate and mind the integration rule if they overlap in time.

Do I have to re-verify investors who already invested with me?

For a 506(c) deal, you need reasonable steps to verify each purchaser in that offering. Whether an earlier verification can be relied on is a question for your securities attorney, and it depends on how recent it is.

Can a non-accredited friend invest in a 506(c) deal?

No. Every purchaser in a 506(c) offering must be accredited.

Can I advertise a deal and still call it 506(b)?

No. If you use general solicitation, the 506(b) exemption is not available. You would need 506(c) or another exemption.

The exemption has different obligations, and the sponsor carries the burden of verifying. Antifraud liability applies equally to both.
