You most definitely can go in on a Fourplex with 3.5% down, primary residence, living in one of the units, find out what purchase power you have, and what the rent rolls for the other units will be to determine your cash flow. 

It will roll into the new basis of your replacement property.

Essentially rolling that equity from each property into the next one, with a cash out refinance each time?

I think it would be important to look at your ROI after your move out and if its worthwhile to hold or potentially sell to roll capital into another more lucrative investment.

I would even be content with neutral or just a small positive cash flow to get it rolling.

It is hard work and takes a long time to get the ball rolling.
