Self Directed 401K Filing Requirements

If I have rolled my 401K money into a self directed 401k and then purchased a property that I rent. Do I file any taxes if I never pull any of my increase / rent money from the property/account. (Such as rent?) I'm thinking if I leave it in the account that is only used for this 401K then it not needed to be reported until I start to draw on the money or property. Or when I sell the property and cash out like a normal 401K?
