talking to appraiser before appraisal in California

[Nathan Williams]

  Im getting an investment loan where the appraised rent amount must met or exceed the mortgage payment.  Long story short the first appraiser the lender used was horrible and gave a horrible appraisal amount of 30% lower than anything you can possibly get in literally anywhere in California (1 star yelp reviews across the board on how bad this guy is).  So now we are ordering up a second appraisal.  This time we want to take no chances and communicate with the appraiser before they come or when they arrive to do the appraisal.  

Any advice on how we should go about this?  We were thinking we have our agent relay some comps to the selling agent to give to the appraiser when he arrives or should we be a little more direct?

thanks
