I wrote a very thorough, well-researched appraisal rebuttal and the lender has accepted it and ordered a second appraisal! I was under the impression the rebuttal went right to the appraiser, and because he was such a jerk, wouldn't be worth the effort. Not so! A second appraisal is the best we could have hoped for!
Congratulations! I had this happen when I was doing a re-fi on a rental property. For whatever reason, I actually got to speak to the appraiser
before she did the appraisal. Because I was an original owner in a large development, I was able to give her some tips to look for when working in the community. For example, if the stove/oven configurations looks like
this, it's builder's standard. However, if it looks like
that, it mean's it's an upgrade, which included pullout shelves and extra cabinetry, plus better finishes. I gave her some other "tells" that she didn't know about. As a result, the comp came in amazingly high. The difference was that she used much better properties for the comps. It was a pretty fun experience. Of course, if I actually wanted to sell the house, I'd have to ask much less, but I got the LTV I needed for the re-fi, for the win.
My tip for you is if there is anything different and better about your property that isn't blatantly obvious (hmmm, or maybe even if it is), consider making a list and leaving it for the appraiser, so they don't miss anything. I would particularly concentrate on things the previous appraiser missed. That will help the second person justify the higher appraisal.
Also, I just remembered this happened with another property we purchased. They were sending an appraiser from way out of the area. Our realtor met them at the house and presented them with a file of good comps in the immediate area, which really helped a lot. You can do the same with info you pull from Zillow, or Redfin or Realtor, etc. It's not the same info as MLS, but it helps guide the appraiser, especially if they're not familiar with the area. Just like with a boss, if you make their job easier for them...
