You need to speak with your tax advisor in general when trying to anticipate future tax benefits or consequences. But, for the sake of discussion, if you are paying the mortgage, you are entitled to some of the tax deductions afforded homeowners. Also, are you and your husband going on the loan and on title? If not then without some sort of contract that says you are part owners, you are in fact renters and may not be entitled to any of the homeownership deductions.
Speak with a Accountant, or Real Estate attorney to make sure that you fully understand your rights and obligations in this transaction.
Feel free to contact me should you have any questions.
