Having joint ownership of 2 house will make you owner of 2 homes (on partial basis). Hence you will need to offer 1 home as your self occupied and another as Deemed to be let out. As suggested by Gridhar, you should offer house as DLOP on which you have taken loan. (however it will make no difference if interest per annum is below Rs. 2 Lakh)
Also i would suggest if you can transfer share of old home to your wife to make her 100% owner. Through this you will be a co owner of only 1 home which you can treat as self occupied.
Also please refer to deductions allowed under Section 80C against payment of loan (if eligible)
