I made an offer that was eventually accepted but it took about a week to hear back. They just were't getting back to the broker for no particular reason. The broker contacted them a few times before getting an answer ("yes, yes, we're happy with that offer"). The initial contract paperwork took another 5 days (broker was slow). They signed their end right away, but I was out of the country by the time the broker finally put it together and sent it to me and I didn't have access to a printer, so it was another 5 days before I got my end back. Now it's with Disney (I assume). Sometimes life just gets in the way and time flies by for some people.
p.s. I'm using the same broker. I've noticed this is much slower and less efficient than the last broker I used. A lot of my emails were answered slow, late, or not at all. Calling her has been most effective so far. I think it's one person working all this, not an office of brokers.
