401k alternatives for professional landlords?
I'm in my 30s. Have portfolio of dozens of units. Net passive income is pretty comfy. In fact, 100% of my income is now passive.
So, this morning I suddenly became interested in starting a retirement thing for myself. Up to now, I have been treating my investment venture as my retirement. So I haven't really looked into this before.
From what I have found on the internet, you can't use passive income for contribution in something like solo401k. But most of what I have found online are of people having 1 or 2 properties while their main income is a full tome job. That is why I am asking my question here.
Those who have been doing this forever, how do I start a retirement thing with only passive income?
