Quit Claim for Income Tax Purposes

For 3 years, I have lived with my boyfriend and paid the mortgage and taxes on his place - he has equity, but no cash, I have cash, but no equity - and it is comparable to the rent I would pay in this area. (Florida Keys). I have not been able to deduct the interest for the past 2 years, but would like to deduct interest and property taxes next year. I need these deductions to lower my federal tax liability, which is high. If he quit claims the deed to the property, and we file jointly - as Florida is a common law state - will the mortgage interest and taxes then be deductible from my income? He has zero income - doesn't file taxes now - as none of his assets are liquid - it is property only.
