Basically what I do is help and show people how to use some of their savings to create streams of income through the investment of multi-family apartments.

All it takes is one leaky tank in the ground , or a diesel spill at the pump , to cost you tens to hundreds of thousands . 

It's not bulletproof by any means but most likely one of the last income streams to fail if the economy really hits the fan. 

I listened to a podcast a while back where the interviewee stated that he had luck using the online auctions sites and he had a steady stream of properties that he was acquiring with perceived ease.

You need a business or self-employment activity that generates active income in order to be able to establish a Solo 401k plan (which is way more powerful and advantageous comparing to SD IRA), therefore SD Solo 401k plan will not work for everyone, but pretty much anyone can setup SD IRA.Passive income in itself is not bad, I think it should be goal for every investor to create an income stream to replace any active or earned income and achieve financial independence.

My income covers my expenses, but I am looking for an additional stream of income I can use to help me save for a down payment.

So during the time you flip, you are building the passive stream up so that when you decide you're tired of flipping, you may have built enough passive streams to help you financially through that transition.Another opportunity you have, if it's something of any interest (may not be for a lot), is that you can start making your flipping more passive at some point.

@Eric Black I feel the same way as you because I actually thought using the money to invest in turnkey rentals that is already producing steady streams of income was a good thing.

It took a little effort to find a deal that worked for both of us but now that this is completed we may go further and transfer some more properties by land contract.Investors who wish to adjust their portfolios, landlords who wish to curtail the management of their properties but who do not have immediate plans for the proceeds from a sale, people who would prefer a stream of income rather than a lump sum (often for tax reasons), and many others may be open to contracts for deeds.
