The answer is: it depends. Due to the ERISA regulations and other IRS-prohibited transaction rules, sponsors may or may not allow investment through your 401k. It will depend on the offering and the sponsor. CrowdStreet cannot make the determination of whether an investor can or should invest in a particular offering as it relates to retirement plans.
We advise investors or prospective investors to contact a financial advisor, tax advisor, and/or attorney prior to investment and should also gather information from the sponsor as to whether or not they will accept it.
