We are a unregd in GST partnership firm having a open plot, appointed a builder to construct the buliding with labour and material vide an regd agreement and paid 50% advance on agreement
According to construction agreement builder will complete the work in next 6 months which will fall in next financial year

My question is

1.when he will raise the GST invoice in our name now at the time of payment or after completion of work( We have to pay the remaining balance in 2-3 installments according to the work)
2. Is it compulsory for us to take GST registration as contract is more than 20 lakhs
3.if we take GST registration can we claim the input credit for the GST paid to the builder and if we can, in which items it is allowed like rent received or receivable in future
4.if we take GST registration should we deduct any TDS in GST LAW

Thanks in advance
