1 Can he claim property tax on his tax return without splitting with me? You each can deduct what you actually paid on the mortgage interest and RE taxes.
2 When we sell this house in the future, do we need to split real estate gain/loss? Or one person can claim all? If you sell a property that you jointly own then each of you will report the portion of the sale based on the ownership %. Before you sell consult a local RE attorney and/or a local tax pro to see what your options are in your state.
3 Is gift tax involved anytime at purchase or selling of the house? Nothing is being gifted when you buy however possibly when you sell depending on what you do with the titling prior to the sale ... again seek local professional guidance.
