PM allowed lease to start after 1 month - Is this normal?

[Ramon Flores]

Hello everyone I have a property management question. My SFH was listed for rent on 8/15. On 8/17 I received a notification saying that they found a tenant and the lease starts on 9/17 and ends 8/31 next year . Now I assumed this was a typo and I assumed the tenant was moving in quickly. Well today I found out that the tenant's lease really does start on 9/17.

Personally I am already upset with this PM because they took a month and a half to turn over a property that needed minor repairs. Long story short the contractor had a death in the family and it took longer. Now I am okay with this but I am unsure what to think about the PM allowing a 1 month gap before they move in. 

Is this normal for property managers? Do a lot of leases start 1 month after? I am unsure if I should be upset or not. At this point my property will be vacant for 2.5 months.

Thanks for the help!
