Investment property . rent half, live in half

[Michael A.]

Are there any special things to consider when looking at a property for both your primary residence and also to rent out the other half of the house?

I know that all the mortgage interest is still completely deductible.. and I would assume that I could write off 1/2 of the depreciation of the house. Would only half of the expenses/upkeep be deductible?

Any good rules or strategies to follow when looking at an investment property for both primary residence and also half rental would be really appreciated.

Thanks!
