I am an investor and want to help a searcher acquire a business. My solo 401(k) will invest a certain amount in exchange for 35% of the business. Since the searcher will be using an SBA loan, anyone holding 20% or more of the shares is normally required to provide a personal guarantee. However, since my 401(k) is the entity that will be investing, 401(k) rules prohibit any personal guarantee. So, in this case, will the SBA waive the requirement? If not, what is the solution to these conflicting requirements?
