California home lease laws/taxes
	
	
		We sold our home in a short sale and my son purchased the home we currently live in.  Our intent is to buy it from him, but the short sale prohibits us from obtaining a mortgage for three years.
We are getting slammed in taxes because we are not able to claim the mortgage interest even though we make the mortgage payment since the loan was taken out by our son.
Is there any kind of situation or agreement (lease option or other) that would allow us to claim the mortgage interest?
Thanks
