Refi of Rental #1 Delayed

I got a call from my mortgage broker today. Apparently, the appraisal of Rental #1 hasn't been done yet! I had an appraisal from late last year, so we were trying to use the same appraiser to do the new appraisal, figuring it would be less work for him and it could be done quickly. That turned out not to be the case. My mortgage broker says the appraiser is not returning his calls and is just blowing him off, so we're going to use a different appraiser who should be able to get the job done in about 72 hours. I hope this whole refi can be wrapped up by the 15th of the month.
