Can take a hard money loan option no income no doc at 30% down on the purchase getting the 100% of construction 

From a lender perspective, multi family is also a great strategy as the income of the other unit(s) will help you to qualify for a higher purchase price.

Remember you have to pay income taxes on your profit, figure 20% for that....

I want to get at least one passive income generator under my belt and then do a few flips for some active income. - my questions are: where do I start?

Accumulated over $400k a year in passive income.4.

I am not planning on quitting my day job anytime soon but rather my hope is to gradually grow the amount of income I am able to bring in over the next 5 years to be in a position to make Real Estate my full time gig. 

For me, it was my way of easing into the rental business and also a way for them to start living on their own.So I get less income than I could AND I lose tax breaks?  

You can always start off by house hacking meaning you live in one UNIT or ROOM and renting out the other vacant units/rooms to offset your monthly mortgage payment.There are several ways to run and make sure you are maximizing your rental income while keeping your living expense as low as possible.

I have no other income than from my 3 STR's. 

I have one of my guys walking a duplex today, All in should be 75k, rents will be 900/900 so about 14k- 15k NET income so 20% ish.
