Keeping first home as rental and buying another

[Don Parent]

All right so my wife and I recently bought our first home, we financed it with a USDA hundred percent financed loan. We are thinking about trying to find another home and keep this one as a rental property. My wife seems to think that we can't keep it as a rental property because we don't have enough equity built into it yet. My question is does anybody have any experience with this and can shed some light on the subject.
