@Adam A.If you take property from your Solo 401k via "in-kind distribution" you would have to appraise the property by independent third party appraisal and the value of the property will be taxable amount.

A lot of the times, those piers are independent of each other.

As for your concern with executing documents, the LLC operating agreement (or LLP partnership agreement) specifies the delegation of authority of the managing members (or partners), so you can set it up to explicitly state that each member can act independently to make decisions on behalf of the trust. 

It is slowing down my path to financial independence which is way more important to me than having a nice house.

Congratulations on embarking on the road to financial independence!

In a hot market, which we are and have been in, depending on the terms of your lease option deal, if prices back up and your tenant buyer cannot qualify in, say 2-3 years, and their is any equity in the deal for the TB and especially if they have paid you 2-5% as a "deposit" or "down-payment", this is a red flag, which could result in a lawsuit. 

You’ll simply need to focus on remediation in your own unit.If you have a local independent agent.

It's against the law every state because you're a licensed broker/agent/consultant and that is what you do for a living (you're an independent contractor) you're not working as an employee nor a contractor for the MLS. you'll have to run the fee's through your broker in order to stay legal and you may want to detail to your broker office what you'll be doing.If you own your own company then you'll know how to proceed.

Independent analysis have shown actual returns are as low as 1-2%. 

I have this Idea of taking a 20% withdraw for a down payment out of my 401k to avoid PMI costs and down the road to grow my properties to gain financial independence.
