For my rental property activity, I may not meet the material participation rules for an active activity, but I do have an active role in the operation of my rental activity. 

It comes with the Participant Loan feature allowing you to borrow from your account up to $50K tax free, which is not available with an IRA.Any investment made with your Solo 401k (you have virtually unlimited investment options) grow tax-deferred (or tax free if you chose to utilize the Roth sub-account of your Solo 401k) and do not require a custodian consent, unlike with SDIRA.

Over the course of many years, this will add up to significant savings that you can later borrow against for a project if you choose, or even withdraw from to purchase a primary residence.Now, where your $30K comes in would be only IF, by participating in the full match of the 401K plan, your paycheck is dwindled below what you can live on, use your $30K to supplement those savings funds.I hope that makes sense.

It'll only get cured if everyone participates, though.

But if you qualify, you can take up to 25k losses - active participation exception. 

When i first started, I was doing the house hacking method, then my husband and I would do flips/brrrs in places were we could regularly drive by. to date, I have only invested passively in deals that I can't physically observe/participate in - but I'm a bit of a control freak in this regard.If you decide to invest in an area where you don't live- obviously pay attention to what these other folks said about location, sunbelt, etc.

This will allow you to have the best of both worlds: investment participation on the back end plus fees along the way.

Frustrated as anyone might be, names are not appropriate.It’s fine to loan to someone who happens to be a participant on BP.

As Josh is hoping, maybe there will be some more participation from these new members.

But if you have a good deal, like a project with 60% LTV, with relative easy path to profit, the private lenders will compete to participate in your deal.In other words, you have bigger fish to fry first - finding great deals.
