If I make $10K and get to reinvest that $10K into the next deal, I will create more money than if I make that same $10K but have to give up $3K to taxes and then can only roll forward $7K to the next deal.The reason to invest a Solo 401(k) in real estate is not specifically tax savings as compared to investing in real estate personally.  

Just testing the Waters.

Get an inspection, make sure you don't need any major repairs and scrutinize the rent roll.

BRRRR the crap out of home, get the snowball formed, get the snowball rolling down hill, get the snowball velocity and momentum, HELOC just becomes a LOC for emergency use and buying quickly. 

(This is where someone would chime in if I have this wrong.)My question is: Can I roll over my existing Roth Solo 401k into a Self-directed Roth Solo 401k?

Talk to a regional bank or credit union, they can get you rolling.

I had to laugh that they did a lead dust test at the most recent house of mine that they inspected... which was built in 1991.

Enough to buy a new Rolls Royce ($450,000), or more (grossed up for inflation)?

Does that mean Rolling in Money Laughing Outloud?
