What i can contribute to someone now is my time, and my work ethic.   

I decided to build a trustworthy branded business as we've always provided quality finished products, contributing to the neighborhoods we serve.We are now buying all of our houses off market and direct from sellers through various forms of (expensive) advertising (Google AdWords, radio spots) and are starting to get direct referrals from previous happy home sellers.Now that we are currently managing 7 rehabs we've faced a ton of challenges.

That being said I have my 401k which I contribute to monthly that will provide a sufficient retirement decades from now.

However, they are almost certainly contributing to your “poor credit” if they’re carrying a balance because they’re still going to factor into your overall credit utilization.

If I partnered with you with me contributing the money and you contributing the expertise and us splitting the net from the sale I would expect your sweat would be part of your contribution. 

As an owner-only business retirement plan, the Solo 401(k) has higher contribution limits, allowing you to build your savings on the front end as well as providing investment flexibility.

The "user" member has also contributed capital to purchase the property, and pays for its expenses, including property taxes, HOA fees, insurance and repairs.

Basically you are dissolving the old partnership, and contributed property to new partnership. 

Hopefully I can not only learn but also contribute. :)

On the other hand, if the fee was just going to some "guru" who organized this meeting and didn't contribute anything more than passing around the collection plate, then I'd seriously question the need for the fee.The real benefit should be the information you guys share amongst each other in the interest of learning and helping each other out, not helping just one of the members (or supposed "guru") pad his/her pockets through the collection of fees.Just my two cents.
