4 unit "package deal" + primary residence financing question

[Mathew Deines]

I am trying to connect some dots here. I am looking at a 4 unit package deal (out of state). I currently have a mortgage on my primary residence.

What would my options be for financing the 4 units? 

If I took out a mortgage on each one, then I would have 5 in my name. 

Do I look for a portfolio lender on this deal and then only have 2 mortgages? 

Or do I only put 2 of the 4 units in my name and 2 in the wife's name, so that we both only have 3 mortgages each?

Any thoughts?
