Second owner occupied loan

[Remone R.]

So we bought a 4 unit as FHA owner occupied feb.2017 and just refinanced to conventional last month as owner occupied. Now my question is how long do we have to stay in the property before we can purchase another one as owner occupied? We hear different answers and are not sure. If we have a family change such as (a baby) will that warrant buying another property that may be have more bedrooms? Or do we have to wait another year before we can make another purchase.
