Moving whoa's

So, a condition of our offer was that we wanted to start moving stuff in before the close, since the house we are moving to was empty. We asked to start 6/30 to give ourselves a month. Our offer was accepted.
6/23 they said that we would need a letter of commitment from our bank. So, we asked for one of those. That took a week instead of the could days we were told to expect, and that was a fax instead of the mail it was supposed to be.
7/3 They got the letter and said - oh, you need insurance before you can move stuff in. insurance has to wait until Monday to send someone out to the house. A nice long weekend wasted.
7/7 The insurance company says they only cover 2 weeks of pre-possession.

I'm about ready to just get an apartment and just back out of all this crap.
