Hello /r/personalfinance

Apologies if this isn't the right place to post this. My SO and I recently signed the lease on a 2 bedroom apartment beginning September 1, and have sublet our current apartment also beginning September 1. 

The current tenant in our new apartment said they would be moving out August 7 (they did) and that we could move in earlier if we choose. As a result, building management told us  - verbally and over emai - that they would get the house cleaned up for us (they have promised to rip out the carpet, add laminate floors, change the dishwasher, stove, and blinds) by September 1. We were told that they would let us know about our potential move-in date once they could estimate how long it would take to get the work done.

Yesterday, building management emailed us and said that the current tenant who has already moved out isn't willing to give back their keys until August 31st. She asked if we could move in later than September 1 to give them time to get the work done. We said no - our apartment has already been sublet as of September 1. We provided her with three options:

- Talk to the current tenant and see if they are willing to give the keys back sooner
- Give us another apartment in the building temporarily until ours is ready
- We move in as scheduled, and get the contractors to work around us and in a piecemeal fashion

She said no to all of the above, and instead asked if we would be willing to pay the current tenant one week of rent to ask her to move out early. Or if we could move in later than Sep 1, they would prorate our rent.

What are our options? What is the best way to handle this?
<bot>: Building management is asking us to move in later than date on the lease, or pay current tenants to move out early because they promised us apartment improvements by Sep 1, which they are no longer able to provide. How to respond?
