Self Storage Financing Newbie

[Justin Reinhardt]

I have always lived by the rule "Fail Fast" (without ever accepting failure). I mean this by way of I don't like to sit and over research (I don't accept the fail part). I learn best by way of Trial and Error with preparation. I like to figure out what works and doesn't work for me. 

I am looking at some possible facilities to buy but was curious what is the best form of financing my first project. I have about 300k available in my 401k and am thinking about using that to finance it completely myself. Is it better to take out an SBA / conventional loan OR is it better for me to use my personal funds? I don't plan on living off my 401K when I retire since that isn't near enough so really I would like to use that money to invest. 

Any advice is welcome! *1st post*
