You needed to look at your lease very carefully before you vacated.
i.e. my original lease on the property I just vacated (signed in 4/07) asked for 30 days notice and if I was still in the property on the first day of the next month, I was liable for a full month's rent.
I signed last year's lease around the 10th of May 2008. However, when I knew I was not going to renew the lease (cheaper rents & this landlord was not going to lower rent), I sent him a notice to vacate on March 30th, 2009, a full 30 days prior to vacating & told him I would be out of the property on April 30th.
I just received a letter from landlord (certified) regarding damages. (yes, front door did get damaged on move out). He's keeping the ENTIRE security deposit for door replacement (it was an old door & had to be rushed, custom made that sort of bs) and then some. I knew this was going to happen as he's not known to give back that deposit.
Now in either my case or yours, a breakdown of costs can be requested. You or I might not like what we see.
Sh*t happens; I always go with the "don't expect the security deposit back" school of thought because that's been my experience.
Always read the lease and know what you're up against.
It might cost the landlord more to deal with you out of state as well & they might just drop it all together. Explore your options!
