Building a duplex worth it?

[Jennifer Mullen]

My husband and I are new to investing and are considering building a duplex and need some advise on whether this is a good deal or not. The land purchase price is 33k, total cost to construct including hook ups, excavation etc would end up being about 400k. Each unit would be 3 bed, 2.25 bath and 1600 sq feet. We estimate we could rent each unit for at least $1600/mo. based on comparables. Our total mortgage payment would be kept at $1600/mo or less given the cash amount we would put towards the deal. We plan to occupy one side temporarily, then move out and rent both sides. Does this seem like a good idea??
