Income tax dedcution benefit

Hello,

I bought an under construction flat from a bulider, took a home loan of 220000 in 2011. I kept it for around 1.5 years and paid 2 laks of pre EMI as interest. I sold it and the time I sold it was still under construction. I know the income tax benefit can be availed on the interest paid in equal amount for 5 years, but only if the possession is provided by the builder.

Need help on how to avail the tax benifit in this situation.

Thanks,

Yash
