Schedule al house property

Sir,
I am a resident Indian needing to submit AL sch as per my income slab. My query is regarding a residential flat for which I have paid an advance (by cheque) to the builder but have not got possession or registration done. The building is still under construction.

My question is
1. Should i show the flat as a residential property 
2. If not, how do i show the advance paid to the builder

Thanks in advance for the response.
