Manufactured / alternative housing financing and considerations

I'm looking to container housing / log cabin housing (kit) as STR/MTR/LTR and am curious how the process, permitting, zoning and financing differs from "normal" stickbuilt construction. What department(s) do I contact in the city/county? Is the land financing separate or can they be including with the house purchase & delivery. Is this a construction loan? Can I use conventional? Could I buy a property that has a lot of acreage and build / add a few of these or would I have to parcel? If it is rural land, can USDA be used?
