Solo401k @ The Tax Man

Hi all I have a Solo401k setup and want to use 90% of it to purchase multiple rental properties.  I also now want access to the passive rental income from the properties instead of it sitting in my 401k.   

1. Are there any roadblocks to transferring the properties from the 401k to me for ownership? 

2. Since this means the solo401k would be closed would the IRS only tax me for the 10% still remaining upon distribution?

Basically I want my rental income to use as I please but trying to ensure the IRS gets the minimal.  

Thanks in advance for feedback all.
