@Loren Whitney I guess I am still confused with the 50% limit.If I am reading the Internal Revenue Code Section 4975 correctly, it applies to a partnership formed by an IRA holder and other non-IRA holders (such as father, brother...) and the IRA holder cannot hold more than a 50% interest in the joint venture or it would be a prohibited transaction.What about a case of say husband and wife, two partners, both participating from their own SDIRA (or Solor-401K), in a 70%-30% or 60%-40% (depending on the proportion of the funds available from their respective IRAs), that should work? 

Or some are setup as a joint venture, where they share in the profits and losses.   

Hello investors,I have a potential joint venture deal in place where I would be bringing the buyer to the deal; it wouldn't be a double close so how should I proceed?

Joint venture with people but don't go into partnership with anyone.

Sam, Would you be interested in a possible Joint Venture on this home? 

To me the answer seems joint venture partnerships.  

Our understanding is that we should file income and expense for the rentals on Schedule E and that we should treat them as jointly owned. 

A healthy self-storage market will have a rental rate of around $1 per square foot.

There are other issues with Jesse's arrangement, liens can be properly set up, but if the property is in the LLC, the note should be in the name of the LLC with personal guarantees, that guarantee could be from one partner, that's not generally accepted practice, guarantees are joint and severally being up to the lender.

Houses are above $500k and I have an average credit score, a couple of thousands in a 401 k, another couple of thousands in a joint money market savings account with my boyfriend, and a salary of about $2k monthly.
