Lots of grey area in agreement which we’re going to sign

We booked apartment in 2019 and made all payments based on their milestones. Now it’s time to do registration. But there are many clauses in agreement which is really weird. Things which I am concerned. From Possession Intimation letter 1. *Maintenance amount*- This is starting from March 10 but flat is not mine. They also mentioned “if no handover is taken within the said Period, it shall be assumed that your right to take handover is waived and no grievances against them” This statement proves that flat is not mine and why should I pay maintenance. From Agreement Draft 2. *Water sources* - They mentioned there is no water source presently and it will be outsourced. But there is no writing about borewells, tomorrow they may plan to sell same water to us. Did anyone saw borewells? Are there any borewell? If only outsourced water out maintenance gonna raise to 10k 3. *Inspection of our flat* - They mentioned purchaser have inspected everything and agrees not take any concerns after handover. This is really makes me doubt as they’re not allowing us to visit and they don’t allow any third party inspection. 4. *Interior work timing *- Based on their timing we can work only 6 hours per day and it’s gonna take months to finish. Also me and my wife working we can’t visit weekdays. I prefer my workers work on weekends too. From handover manual 5. *Timing of amenities*- This is real cheating and false promise where they mentioned 24 hour amenities in all their advertisements 6. We have to pay 50k when we do interior and only 40k will be returned. 10k they will take in name of cleaning common area. What’s maintenance then? Why do we need to pay to them if i am doing something inside my home. Why do they care who is coming inside my home is it worker or guest as we’re sole responsible for all guest coming to our apartment. 7. Their employees can enter anytime inside my home to do inspections about structural change without prior notice.
