I am about to buy a residencial single family in CA. The mortgage will be 50/50 with a co-signer (who is providing 40% down and to avoid the gift tax, she will co-sign) who already owns a primary residence, so we have to classify this property as investment property (per our loan co). However, I will use it as my primary residence.
