Self Directed IRA as well as Employer 401K

[Colin M.]

Hi there, 

I currently hold a 401k through my employer which i contribute to weekly. Im looking to do a couple things here:-

1. I already max out this 401K every year but want to put away MORE pre-tax dollars, can i set up a personal Self Directed IRA, in addition to this 401K, so i can minimize my weekly tax bit.
2. i want to buy RE through my 401k, which is not allowed, so this is a second reason for wanting to setup a Self Directed IRA personally.

With the above notes, if you do this, has your employer given you any resistance in setting up pre-tax dollars to be sent to your IRA? My 401K Financial Adviser told me that i wasnt allowed to have both, but some friends say they have both. Im assuming FA just doesnt want me shopping elsewhere! Or am I missing something bigger?

Appreciate any feedback.
