If I need by some chance I need extra money I can fund it with money from my side business.

I was out of college (just earned my degree in Culinary Arts) and was constantly running out of money.

The biggest question you need to ask yourself is if you are doing this to afford a property you otherwise couldn’t afford or to save money period, that will lead to very different conclusions about where/if to buy. 

As you may have found in your search, there are lenders that will lend up to 80% of the appraised value on investment properties and don't require an appraisal.Let me know if you'd like me to point you in the right direction.I have not; I'm still working on acquiring my next house hack, but when I need it, I'll probably use a combo of hard money and margin loan.

I tend to save the most money by being able to do my own stuff up to code. 

If it is a private money/ commercial style  lender, it is a relatively simple process.

I want to make money when I am sleeping or not working. 

I lost my money, Hope you don't! 

If you have a self directed account and invest pre-tax money into illiquid assets like syndication or mortgage notes they will come in at a value of less than the principal.

The same money could buy 1-2 full properties that would rent for more, depending on the market you choose.
