Buying Lot for a Prefab, What types of loan(s) is the best?

[Jesse Reese]

Okay so the setup is there are a few lots out near the Portland/Vancouver area in Portland.  It is zoned correctly for prefabs (Zoned for single/multifamily & Prefab is okay) and my thought was to purchase the lot and a prefab home for it. The sticker price not including assembly of the prefab is going to be between $80,000 and $110,000 the land is around $50,000. 

What types of financing do you need in this case? It seems to me that I might need two loans for this or some type of construction loan.  Please help!
