However if the campus buys some land and then ends up selling it before the year is over to a non-profit or some other entity it is not subject to UBIT.One is an occurrence.

I'd choose option 4, which goes along with what @Tara G. is saying:Call the county/city entity and ask them about it, or maybe even have them come out and tell you if it's in code or not.

I put these words in quotes because the IRS and Dept of Labor and several other Govt entities will see your "contractor" as an employee of your company if you "track" them in the way I think you're referring to.

The benefit here is that you’re a known entity and have the proven relationship.

Those are two separate entities and can't be using the same EIN.

A self-directed 401k is sponsored by your company, not the other way around.You could create an LLC (or any other type of entity) and set up an SD401k under it.

Im going to assume you are doing this personally not under a entity, since your buying Multi's Id suggest an entity, but talk to a lawyer.The Insurance company giving you the BR policy will have Min Ins limits of liability for your subcontractors.

If you have a reasonable expectation of moving forward I would form the entity first so that you could write all the contracts in that entities names, etc from the beginning.

Since if I buy a property it would be with my LLC or LP or a Trust set up with a business entity as the beneficiary.

They will likely be a new type of regulated entity once Title III of the JOBS act is finalized by the Securities and Exchange Commission, but today there is no such thing as a portal.
