using usda loan for investing

[Josh Fincher]

hello,

I'm wanting to buy a 4 plex building using a usda loan and occupy it for a year then find another one and move into it, also, for a year and, also, with a usda loan.  rinse and repeat until I feel like I have enough cash flow to live comfortably and still save for other investments.  My problem is I'm not sure if it's legal.  I've looked everywhere and even downloaded a usda guideline booklet and cannot find anything about it except to say that you must occupy the building, but does not say for how long or if you can buy another property while already having one with usda.  can anyone please help me with this?  thanks..
